SERVSWITCH™ MULTI  
2.1 Overview  
2. Introduction  
®
®
With the ServSwitch Multi™, multiple users at your site can operate sets of IBM PC compatible, Apple  
®
®
Macintosh , Sun Microsystems , and other computers at the same time. Each ServSwitch Multi Expansion  
Chassis (product code KV160A-R2)—the preferred “starting” model for mid- to large-scale applications—  
supports as many as 14 external connections through plug-in cards. You can connect computers,  
keyboard/monitor/mouse/etc. user stations, terminals, and other ServSwitch Multi units to the system through  
those cards. Front-panel LEDs show which of the Chassis’ card slots is “on line” (has a card installed that is  
connected to powered equipment) and, of these, which slots are currently selected by system users.  
ServSwitch Multi Base Units (KV150A-R2) are like the Expansion Chassis, but are more suited for use in  
small-scale applications such as those involving a single Multi unit that doesn’t require frequent  
reconfiguration. In the Base Units, one of the plug-in card slots is replaced with a “local console module,” a  
user-station port with dedicated front-panel connectors for a nearby keyboard, monitor, mouse, and other  
peripherals. (Unfortunately, the ServSwitch Multi’s on-screen display menus can’t be used with this local  
console.) The Base Unit has front-panel pushbuttons for card-slot selection, LEDs that show which slots are  
currently selected by system users, and a two-character alphanumeric display that shows which port is currently  
selected by the local console.  
The ServSwitch Multi MX (KV155A) is a smaller version of the Base Unit with four card slots plus a local  
console, without the alphanumeric display. It only supports two video/control pathways instead of the usual  
four. It’s intended for desk- or countertop use only in individual or local-cluster applications.  
The ServSwitch Multi SB (KV162RA) is virtually identical to the Expansion Chassis, except that it supports  
eight video/control pathways instead of the usual four, so that users can independently access as many as eight  
of the attached computers.  
The ServSwitch Multi Hub (KV170RA) is designed to be a centerpiece for the very biggest applications. It has  
nine slots exclusively for special concentrated Transmit and Receive Modules (KV1701C and KV1702C  
respectively) that have 16 ports each. Using the Hub can greatly reduce the number of regular Expansion  
Cards and expansion cables needed for Multi systems with large numbers of computers and users. The Hub can  
be controlled with front-mounted pushbuttons and a 4-x-20-character display.

CHAPTER 2: Introduction  
2.2 Features and Benefits  
Here are some of the ServSwitch Multi’s features:  
• Automatic booting of all attached computers. ServSwitch Multi’s AutoBoot feature boots all of your  
attached computers during initial power-up or after a power failure. All computers are booted transparently  
and simultaneously, eliminating the need for operator intervention. Computers may be powered up one at  
a time or all at once.  
• Built-in computer-port scanning. You can use the ServSwitch Multi’s built-in scanning feature to  
automatically monitor or scan all of your attached computer channels sequentially without intervention.  
When the ServSwitch Multi detects keyboard or mouse activity, scanning is suspended until all activity stops.  
Scanning then resumes with the next computer in sequence. The “dwell time” (the length of time each  
computer channel’s video output remains on the screen) is configurable and can be changed at any time.  
• Multiplatform support. The ServSwitch Multi adds multiplatform capabilities to your system by  
simultaneously supporting any combination of IBM PC compatible, Mac , Sun , IBM RISC System/6000  
®
®
®
®
®
®
®
®
(RS/6000 ), Silicon Graphics (SGI ), or Hewlett-Packard (HP ) computers. Now you can switch easily  
®
among your PCs, Mac computers, and workstations with the push of a button. Use any type of keyboard  
and mouse to access any computer in the system. For example, a PC keyboard and mouse can operate a Sun  
workstation almost as easily as a Sun keyboard and mouse will operate an attached PC.  
• Multiuser support. Instead of just one user having access to the attached computers, the ServSwitch Multi  
allows up to two, four, or eight users simultaneous access to different computers in the system. If two or  
more users need access to the same computer, they can “share” access to it through the switch. “Sharing”  
means that multiple users can switch to the same computer at the same time. Everyone can see that  
computer’s video, but only one can enter data at any given moment; a timeout scheme is used to arbitrate  
user contention for keyboard and mouse control.  
• Expansion capability. You can manage even large numbers of computers from a limited number of user  
stations by installing expansion transmit and receive cards in multiple ServSwitch Multis, then cabling those  
cards together to form a cascaded system. In fact, such a system with one master user station can control  
literally thousands of computers this way.  
• Multimedia and serial-communication support. With the proper peripheral equipment and cabling, every  
user in a ServSwitch Multi system can access and control the attached computer equipment not only  
through their dedicated keyboard, mouse, and monitor, but also through a dedicated microphone, stereo  
speakers, and/or RS-232 serial port. Modems, serial printers and scanners, and other serial devices are  
accessible through the serial port; if you attach a PC to this port, you can view the Switch’s system  
configuration or firmware-revision level, or download upgraded firmware into the Switch.  
• On-screen management and multilevel security. If you install User Cards with On-Screen Display (our  
product code KV2550C-R2) in your system, you can use a variety of functions through on-screen windows:  
Name your servers for easy recognition, then select them from a pop-up menu; edit channel names and  
addresses; scan; broadcast; or even implement password-based security. With the security options, you can  
assign video only, video/keyboard/mouse, or full access privileges to users, as well as setting an inactivity  
timeout.  
• Modules “Keep Alive” with interface power. The ServSwitch Multi’s CPU-Interface Card modules have  
“Keep Alive” circuitry through which they can draw power from the attached computers if they become  
detached from the ServSwitch Multi or if the ServSwitch Multi loses power. Because the modules remain  
powered in such an emergency, your computers don’t lock up needlessly.

SERVSWITCH™ MULTI  
• Modules are hot-swappable. Because the ServSwitch Multi is a component-based switch, all of its modules  
are field-replaceable plug-in boards which can be added or replaced without disassembling or even  
powering down the system. This “hot-swap” or “hot-plug” capability makes installing, configuring, and  
maintaining the unit much simpler.  
• Firmware is flash-upgradable. You can update the Switch’s firmware without having to power down the  
Switch or remove any installed Cards. The latest firmware is always available through our Web site,  
www.blackbox.com.  
• Rackmountable. All ServSwitch Multi models except the MX can be mounted in a standard 19" equipment  
rack. The SB and Hub models ship ready to mount; the Base Unit and EXP models can be mounted with  
our optional RMK19L and RMK19LE rackmount kits respectively (see Appendix F).

Figure 2-1. A three-computer, three-user-station ServSwitch Multi system.  
* All monitors are multisync types because each shared monitor in a ServSwitch Multi system must be capable of  
synchronizing with the video output of any attached computer.  
†If you use Macintosh console equipment in a multiplatform system, you must use a PC-style serial mouse. This is  
because, although the remapping functions of the ServSwitch Multi (see Section 8.4) make it possible for a Mac  
keyboard attached to the Switch to emulate the functions of a PC or Sun keyboard, at the time of this writing there is  
no way for a one-button Apple mouse attached to the Switch to emulate a mouse with more buttons.

CHAPTER 2: Introduction  
2.4 Limitations and Restrictions  
Keep these things in mind as you plan, design, install, and operate your ServSwitch Multi system:  
• The ServSwitch Multi supports these models of mice:  
®
– Microsoft serial or PS/2 mouse (including the IntelliMouse );  
– Microsoft OEM style serial mouse;  
®
®
®
– Logitech Mouseman and Trackman ;  
– IBM PS/2 style mouse;  
®
– Kensington PS/2 or ADB mouse;  
– Mouse Systems (PC Mouse);  
– Sun Microsystems Laser mouse; and  
– Apple ADB mouse.  
Other manufacturers’ mice generally operate with the ServSwitch Multi, but we cannot guarantee that any  
given mouse will. If you experience problems using an untested mouse, contact Black Box Technical  
Support with the manufacturer and model number of the mouse.  
• Monitors at all user stations must be capable of synchronizing with any attached computer’s video rate. If  
you are unsure whether your monitors have multisync capability, consult the monitor documentation or  
contact your dealer.  
• Use only Black Box supplied cable with the ServSwitch Multi. Poorly constructed or miswired cabling will  
diminish video quality and could possibly damage your equipment.  
• The ServSwitch Multi supports all externally powered speakers that use 3.5-mm miniplugs. We recommend  
that you use powered speakers with the ServSwitch Multi for best performance.  
• Use “mono” microphones with 3.5-mm miniplugs with the ServSwitch Multi. Powered microphones are not  
recommended; if a computer channel is selected that supplies power to the microphones, the microphone  
volume might be muted on that channel.  
• The ServSwitch Multi’s CPU and User Cards autosense EIA/TIA RS-232 serial devices using any data format  
and hardware, software (“inband”), or no flow control: hardware flow control up to 9600 bps, software or  
no flow control up to 115,200 bps. The ServSwitch Multi’s Serial Control Cards support user-configurable  
RS-232 connections from 1200 to 19,200 bps using 7 or 8 data bits; even, odd, or no parity; 1 or 2 stop bits;  
and hardware, software, or no flow control.

SERVSWITCH™ MULTI  
2.5 Safety Precautions  
To avoid potential video or keyboard problems with the ServSwitch Multi, take these precautions:  
• If the site has 3-phase AC power, make sure that each ServSwitch Multi and all of the computers and  
monitors attached to it are on the same phase. For best results, they should be on the same circuit.  
• Use adapter cables supplied by Black Box only.  
To avoid potentially fatal shock and possible damage to equipment, take these precautions as well:  
• Do not use 2-wire extension cords with the ServSwitch Multi.  
• Test the AC outlets that the monitors and computers are plugged into for proper polarity and grounding.  
• Plug the ServSwitch Multi and all monitors and computers into grounded outlets only. If you are plugging  
the Switch and any attached equipment into a backup power supply (BPS) or uninterruptible power supply  
(UPS), you should plug the Switch, monitor, and computers into the same supply if at all possible.  
• With the exception of adding or removing Cards, you should power down the ServSwitch Multi and all  
attached computers before you service the unit in any way. Always disconnect the power cord from the unit  
when you power it down.  
Note that the AC inlet is the ServSwitch Multi’s main disconnect.  
All ServSwitch Multi models are rated for input voltages of 110 to 240 VAC and input frequency of 50 or  
60 Hz. The ServSwitch Multi Hub (KV170RA) is rated for total load-balanced input current of 7 amps: When  
only one power supply is functioning, it will provide all 7 amps, but when both supplies are working, they will  
share the load. All other ServSwitch Multi models are rated for 1.6 amps.  
2.6 The System and Its Components  
2.6.1 THE COMPLETE SERVSWITCH MULTI PACKAGE AND OTHER COMPONENTS YOU’LL NEED  
• Each ServSwitch Multi Base Unit (KV150A-R2) and ServSwitch Multi MX (KV155A) is shipped from the  
factory with an embedded local-console module, a power cord, and a copy of this manual.  
• Each ServSwitch Multi EXP (Expansion Chassis, KV160A-R2) and ServSwitch Multi SB (KV162RA) comes  
from the factory with a power cord and a copy of this manual.  
• Each ServSwitch Multi Hub (KV170RA) comes from the factory with its two power-supply modules and two  
fan assemblies uninstalled. It also comes with two power cords and a copy of this manual.  
If you didn’t receive everything, or if anything arrived damaged, call Black Box right away.  
In addition, you’ll need other components to build a complete ServSwitch Multi system (contact Black Box  
Technical Support if you’re not sure what you’ll need for your application). With the Base Unit, MX, EXP, or  
SB, you’ll need some combination of:  
• One or more Autosensing CPU-Interface Cards (KV2000C) and one or more 8-foot (2.4-m), 20-foot  
(6.1-m), or 30-foot (9.1-m) CPU (Server) Cables to attach servers or other computers to the Switch.  
18

CHAPTER 2: Introduction  
• To attach user stations to the Switch, 1-foot (0.3-m), 10-foot (3-m), or 20-foot (6.1-m) User Cables attached  
to additional Universal User-Interface Cards (KV2500C) or User-Interface Cards with On-Screen Display  
(KV2550C-R2) as necessary—up to a maximum of:  
– one into an MX whose Local Console you’re using;  
– two into an MX whose Local Console you’re not using;  
– three into a Base Unit whose Local Console you’re using;  
– four into an EXP or into a Base Unit whose Local Console you’re not using; or  
– eight into an SB.  
• In a cascaded multi-Switch system, expansion cables as necessary to connect Switches to each other: KV1600  
for 10-foot [3-m] regular expansion cable, KV1600100 for 100-ft. (30.5-m) regular cable, or EYN737MS-MM  
for Category 5 expansion cable.  
• In order to attach terminals, hubs, routers, or other serially accessed control devices to the Switch, you’ll  
need one Serial Control Card (KV1609C) and four Category 5 patch cables (EVMSL05) for every four such  
machines, plus a single Management Card (KV1608C-R2) and a DB9 null-modem cable (EYN257H) to  
hook up a PC to manage the Serial Control Cards with.  
With the Hub you’ll need:  
• Several Transmit Modules (KV1701C) and Receive Modules (KV1702C), plus Category 5 expansion cables  
(EYN737MS-MM) to connect the Hub to the other Switches in your system.  
2.6.2 RACKMOUNTING THE SERVSWITCH MULTI (OPTIONAL)  
The ServSwitch Multi SB and ServSwitch Multi Hub can be mounted in a standard 19" equipment rack without  
any additional hardware. Just match the holes in the protruding ends of the Switch’s faceplate to an  
appropriate set of matching holes on your equipment rack, then fasten the assembly to the rack using your own  
screws, bolts, or cage nuts (not included).  
If you want to mount a ServSwitch Multi Base Unit, you’ll need a ServSwitch Multi Rackmounting Kit  
(RMK19L); to mount a ServSwitch Multi EXP, you’ll need the RMK19LE Kit. See Appendix F for instructions  
on how to rackmount either of these models.  
The ServSwitch Multi MX is not designed to be rackmounted.

2.6.3 DESCRIPTIONS OF THE SERVSWITCH MULTI BASE UNIT AND MX AND THEIR COMPONENTS  
The front panel of a ServSwitch Multi Base Unit (KV150A-R2) or ServSwitch Multi MX (KV155A) has nine  
connectors (shown in Figure 2-2), one for each of these peripheral types:  
• PS/2 keyboard  
• PS/2 mouse  
• Serial mouse  
• Macintosh (Apple Desktop Bus) mouse and keyboard  
• Sun mouse and keyboard  
• VGA video  
• RS-232 serial-port device  
• Microphone  
• Speakers  
You can use these connectors to attach a keyboard, monitor, and mouse (and optionally a microphone,  
speakers, and serial device) to the Switch’s front panel. Any peripherals attached to the front of a Base Unit or  
MX together constitute its local console (user station). Through these peripherals, you can access every  
computer attached to the Switch. (However, the local console has no on-screen display.)

CHAPTER 2: Introduction  
The front panel of the Base Unit has twelve pushbuttons labeled A through L. The front panel of the MX has  
four pushbuttons labeled A through D. You can use these buttons to select the active computer for the local  
console. The indicator lights (LEDs) over the pushbuttons reflect the type of activity, if any, that is taking place  
on each attached computer. The alphanumeric display, located in the upper right-hand corner of the front  
panel on the Base Unit only, shows which computer channel is currently selected by the local console. The local  
console is the only user station affected by the pushbuttons or whose channel is indicated by the Base Unit’s  
alphanumeric display. At Card consoles, which connect to the Base Units and MXs through their rear panels,  
you must use either the console keyboard or an on-screen display to select computer channels. As many as one  
(on the MX) or three (on the Base Unit) Card consoles can have access, as the local console does, to every  
computer on that Switch. (It can be two or four Card consoles if you don’t use the local console at all.) See  
Section 8.3 for details.  
The first slot on the far left end of the rear panels of the ServSwitch Multi Base Unit and MX (shown in  
Figure 2-3) contains the local console’s module; this slot is referred to as “channel N” on the Base Unit and  
“channel E” on the MX. On the Base Unit only, there’s an “option slot” next to the local console’s module,  
referred to as “channel M.” There is no front-panel LED or pushbutton associated with this slot, and it is best  
used for a secondary console or an expansion card. All other slots in either unit may be configured as needed.

SERVSWITCH™ MULTI  
Each Base Unit and MX comes with the local console module preinstalled. You will also need at least one  
Autosensing CPU-Interface Card (our product code KV2000C) for each computer you plan to attach to the  
Switch, as well as one Universal User-Interface Card (KV2500C) or User-Interface Card with On-Screen Display  
(KV2550C-R2) for each secondary console. The CPU-Interface Card, shown in Figure 2-4, has an HD44 female  
connector as a single composite interface for all I/O to and from the attached computer. The User-Interface  
Cards, also shown in Figure 2-4, have an HD62 female connector as a single composite interface for all I/O to  
and from the attached user station.

CHAPTER 2: Introduction  
2.6.4 DESCRIPTIONS OF THE SERVSWITCH MULTI EXP AND SB AND THEIR COMPONENTS  
The front panel of a ServSwitch Multi EXP (Expansion Chassis, KV160A-R2) or a ServSwitch Multi SB  
(KV162RA), shown in Figure 2-7, has fourteen pairs of channel LEDs, each of which corresponds to a channel  
slot in which you can install any kind of ServSwitch Multi Card. The Switch’s front panel also has POWER and  
FAIL LEDs.

Figure 2-7. The front panel of an EXP or SB.  
There are no pushbuttons and no display on the front panel, because EXPs and SBs do not have local consoles;  
they are geared more to be subsidiary expansion units than standalone units, although with a User-Interface  
Card installed they can easily perform all of the same keyboard-activated switching and command functions  
that Base Units and MXs can.  
The rear panels of the ServSwitch Multi EXP and ServSwitch Multi SB look identical to that of the Base Unit  
(shown in Figure 2-3 in Section 2.6.3). However, instead of their leftmost slot containing the local module and  
their next-to-leftmost slot having no corresponding front-panel indicator, all fourteen of the EXP’s and SB’s  
slots are empty, and all of them have a corresponding pair of LEDs on the front panel.  
You will need at least one Autosensing CPU-Interface Card (product code KV2000C) for each computer you  
plan to attach to the EXP or SB, as well as one Universal User-Interface Card (KV2500C) or User-Interface Card  
with On-Screen Display (KV2550C-R2) for each console. These cards and their cables are described in Section  
2.6.3 and are shown in Figures 2-4 through 2-6 on the previous page. You will also need at least one regular  
Expansion Transmit Card (our product code KV1601C) or CAT5 Expansion Transmit Card (KV1603C), shown  
in Figure 2-8 on the next page, if you want consoles on another ServSwitch Multi unit to be able to access  
computers on the EXP. And you will need at least one Expansion Receive Card (KV1602C) or CAT5 Expansion  
Receive Card (KV1604C), also shown in Figure 2-8, if you want consoles on the EXP to be able to access  
computers attached to other ServSwitch Multis. To connect serially accessed control devices such as terminals  
and routers, you’ll need a Management Card (KV1608C-R2) and one or more Serial Control Cards (KV1609C);  
see Chapter 5.

Figure 2-8. The ServSwitch Multi’s Expansion Cards.  
Each regular Expansion Card has two HD26 ports on it (male on the Transmit Card, female on the Receive  
Card); each of these is an endpoint for an independent expansion link. For example, if you run cables from  
both of the ports on a Transmit Card to the corresponding ports on a Receive Card in another unit, two  
different user stations on the other unit will be able to access different computers on the Transmit Card’s unit  
at the same time. Alternatively, you can run a cable from each of the ports on a Transmit Card to a matching  
port on two different Receive Cards, even if they are installed in different ServSwitch Multi units.

CHAPTER 2: Introduction  
Instead of single connectors, the two ports on CAT5 Expansion Cards consist of three RJ-45 sockets each,  
because three 4-pair cables are required to carry all of the signals necessary for expansion. The ports of the  
regular Cards and the CAT5 Cards are shown in Figures 2-9 and 2-10; the pairing of the CAT5 RJ-45 connectors  
is shown in Figure 2-11.

If you are using regular Expansion Transmit and Receive Cards, you will run a regular Expansion Cable  
(shown in Figure 2-12) between a Transmit/Receive Card pair. This cable is available in stock lengths of 10 feet  
(3 m, product code KV1600), 25 feet (7.6 m, KV160025), 50 feet (15.2 m, KV160050), and 100 feet (30.5 m,  
KV160100). If you are using CAT5 Expansion Transmit and Receive Cards, you will run three four-pair, straight-  
through-pinned, solid-conductor CAT5 twisted-pair cables (product code EYN737MS-MM, shown in  
Figure 2-13) between a Transmit/Receive Card pair. This CAT5 cable is available in stock lengths of 10 feet  
(3 m), 50 feet (15.2 m), 100 feet (30.5 m), or 250 feet (76.2 m), or you can order it in custom lengths.

SERVSWITCH™ MULTI  
2.6.5 DESCRIPTION OF THE SERVSWITCH MULTI HUB AND ITS COMPONENTS  
The ServSwitch Multi Hub (KV170RA) is a cube that fits in 9U (15.75", 40 cm) of vertical rack space. Internally,  
it will contain two power supplies and two fan assemblies (for redundancy) once you install them—they’re  
shipped uninstalled to lessen the chance that they might be damaged in transit. The most prominent features  
of the Hub’s front panel, as shown in Figure 2-14, are a 4-x-20-character LCD panel and four associated buttons  
with which you can control and configure the Hub through an internal menu system. The Hub’s front panel  
also has POWER and FAIL LEDs, as well as an RJ-45 serial port that currently has no function but might be  
enabled with future firmware upgrades. The front panel is controlled by a special internal Front-Panel Element.  
The Hub’s nine plug-in Module slots are “channel A” through “channel I.” For Flash-upgrading purposes only,  
the Front-Panel Element is “channel J”; that channel can’t be selected and is not recognized for any other  
purpose.  
POWER  
ESCAPE  
ENTER  
Figure 2-14. The front panel of a Hub.  
The Hub isn’t like the other ServSwitch Multi models. No computers or user-station consoles can be directly  
attached to it. It’s not designed to accept Interface Cards, regular Expansion Cards, or any other type of Card  
that the other models support. Instead, it functions as a central housing for as many as nine Transmit or  
Receive Modules (KV1701C or KV1702C respectively), which each channel up to 16 sets of keyboard, monitor,  
and mouse signals between cascaded ServSwitch Multi units. You’ll run two CAT5 cables from the two ports of a  
CAT5 Expansion Card in some other ServSwitch Multi model to two of the ports on one of the Hub’s Modules.  
This centralized distribution through the Hub makes it possible to assemble very large KVM-switching systems  
using fewer Expansion Cards, fewer cables, and often fewer Switch units. For more information, see Chapter 7.

3. Installing User-Interface Cards,  
User Cables, and Console Devices  
IMPORTANT NOTE  
If you are installing a cascaded ServSwitch Multi system, you should make sure your  
Expansion Cards and Cables are installed properly before you begin installing other  
types of Cards or attaching devices to the system. Refer to Chapter 6 and (if your  
cascaded system includes any ServSwitch Multi Hubs) Chapter 7.  
3.1 Connecting Local-Console Equipment to a Base Unit or MX  
As shown in Figure 3-1, the ServSwitch Multi Base Unit and ServSwitch Multi MX have a group of connectors  
on their front panels to which you can directly connect (without needing extra cables) a local console (user  
station). This console can include a keyboard, monitor, and mouse, as well as a serial device, speakers, and/or  
microphone.  
You can independently plug a single keyboard and a single mouse (each belonging to any platform the  
ServSwitch supports, in any combination) into the local console. However, do not connect more than one  
keyboard, monitor, or mouse to the local console. For example, you may use a Sun mouse and a Mac keyboard  
at the local console at the same time, but you must not connect two keyboards or two mice to the front of the  
unit simultaneously. This could cause your computers to behave unpredictably or even crash.  
The local console operates as if it were connected to a Universal User-Interface Card (KV2500C) rather than  
a User-Interface Card with On-Screen Display (KV2550C-R2)—no on-screen menus are available.

SERVSWITCH™ MULTI  
3.2 Installing User-Interface Cards in a ServSwitch Multi  
To install a Universal User-Interface Card (“UUIC” for short, our product code KV2500C) or User-Interface  
Card with On-Screen Display (“UICD” for short, our product code KV2550C-R2) in a ServSwitch Multi Base  
Unit, MX, EXP, or SB, take these steps:  
1. Position the ServSwitch Multi so that its rear panel is facing you, as shown in Figure 3-3 on the next page.  
Choose an available slot. In most cases, any slot that is covered with a blank (connectorless) panel will be  
available. However, note that on the Base Unit and MX, the local-console module on the far left end of the  
Switch’s rear panel is covered by a blank panel but is not an available slot; no ServSwitch Multi Card of any  
type can be installed in that slot. Remember that the option slot (the slot just to the right of the local-  
console module, which has no corresponding front-panel LED or pushbutton) is an available slot and  
should preferably host a User-Interface Card, Expansion Card, etc., rather than a CPU-Interface Card.  
2.Once you’ve chosen the slot, write down the letter of the corresponding channel in the “Channe Letterl”  
field of this Card’s record in a copy of the User-Interface Cards pages of the System-Configuration Chart  
(see Appendix A). At this time you should also write down what appears on the Card’s label (just to the  
right of the HD62 connector if you look at the connector from the rear) in the Chart’s “Card-Label  
Information” field, and (if the ServSwitch Multi unit is part of a cascaded system) you should write down  
the Switch’s address in the “Switch Address” field as well.  
3.Remove the panel covering the available slot by unscrewing the two Phillips-head screws that hold it in  
place. (Save these screws; you’ll be replacing them momentarily.)  
4.If you look into the open slot on the Switch, you will see “guide tracks” that the top and bottom of the Card  
should slide along when you install it. Slide new User-Interface Card gently into the slot along these tracks,  
until the Card’s HD62 connector lines up flush with the back of the unit, as shown in Figure 3-2.  
Figure 3-2. Inserting a User-Interface Card in the Switch.  
5. Secure the Card in the Switch with the screws you removed in step 3. Retighten the screws completely, but  
do not overtighten them.  
Repeat the above procedure for every User-Interface Card in your system.  
The UUIC and the UICD share the same basic features, but the UICD has a set of on-screen display features  
that the UUIC lacks. For descriptions of these features and how to use them, see Chapter 9.

SERVSWITCH™ MULTI  
3.3 Connecting User Cables and Console Equipment to Your User Cards  
Except for the local consoles on the Base Unit and MX, you’ll use User Cables to connect your consoles to the  
User Cards installed in your ServSwitch Multi. You will need one of these cables for each User-Card console in  
your system. These cables are 1 foot (0.3 m), 10 feet (3 m), or 20 feet (6.1 m) long and have an HD62 male  
connector on one end. They have different numbers of connectors on the other end, depending on the  
options you ordered (see Table 3-1 below and the corresponding subsections on the following pages). In order  
to connect a non-multisync monitor, you’ll also need a special adapter; see Section 3.3.4.  
Things to be aware of when you make User-Cable connections of any type:  
• As you attach the console equipment to each User-Interface Card, finish filling out the Card’s record in the  
System-Configuration Chart (see Appendix A).  
• The Cable’s audio-strand connectors are very similar to each other, but the microphone strand has a blue  
band around it so that you can tell the two apart.  
• Similarly, on some versions of the Cable, the mouse-strand connector is the same as the connector on the  
keyboard strand or serial-device strand, so the mouse strand has a yellow band around it so you can tell it  
apart.  
• Some speakers, headphones, and microphones have plugs and jacks different from the type that the  
ServSwitch Multi’s audio cables are designed for. If this is the situation with your audio equipment, you will  
need adapters to connect your equipment to the ServSwitch Multi system. These adapters are commonly  
available; call your local electronics-supply store for more information.  
• For serial connections, if you want to connect an Apple device or a serial device with a connector other than  
a DB9 female, see Appendix E.

To install your cabling and console equipment at each IBM type secondary console, first plug the User Cable’s  
HD62 connector into the matching connector on the User-Interface Card. When you’re sure the connection is  
firmly seated, secure it by tightening the associated thumbscrews.  
Now plug the cables from your keyboard, mouse, and monitor into the matching connectors on the User  
Cable. (You might be able to use your non-multisync RS/6000, SGI, or HP monitor instead of a VGA monitor;  
®
see Section 3.3.4.) If the User Cable is an audio type, it will have three additional connectors: two RCA jacks  
for a mono microphone and stereo speakers or headphones, and a DB9 male connector for a serial device.  
Attach any appropriate equipment as desired.

3.3.2 FOR APPLE MACINTOSH STYLE KEYBOARD AND MOUSE  
If you are using an Apple Macintosh style (ADB, Apple Desktop Bus) keyboard and an ADB or RS-232 mouse at  
a given console, the User Cable you’ll need will be labeled KV2700, KV2710, or KV2740 depending on the  
options you ordered (see Table 3-1 at the start of Section 3.3; the audio cable comes in 1-ft. [0.3-m] and 10-ft.

To install your cabling and console equipment at each Mac type secondary console, first plug the User Cable’s  
HD62 connector into the matching connector on the User-Interface Card. When you’re sure the connection is  
firmly seated, secure it by tightening the associated thumbscrews.  
Now plug the cables from your ADB keyboard and mouse and from your multisync monitor into the  
matching connectors on the User Cable. (In a multiplatform application, you’ll have to plug a PC-type RS-232  
serial mouse into the Cable’s serial-mouse connector and use that instead of the ADB mouse. This is because  
one-button Apple mice can’t perform all of the functions of two- or three-button mice. Also, note that the stock  
cable is designed to connect to a multisync monitor rather than an Apple monitor; a multisync monitor will be  
necessary in most situations, because most people who have Apple computers in their system have PCs as well.  
However, if your Mac monitor is capable of syncing to and displaying the video output of all of your computers,  
you can use the KV16MAC adapter to connect it to the system; see Section 3.3.4.)  
If the User Cable is an audio type, it will have three additional connectors: two RCA jacks for a mono  
microphone and stereo speakers or headphones, and a DB9 male connector for an RS-232 serial device. Attach  
any appropriate equipment as desired.

firmly seated, secure it by tightening the associated thumbscrews.  
Now plug the cables from your Sun keyboard, your Sun or serial mouse, and your multisync monitor into the  
matching connectors on the User Cable. (Note that the stock cable is designed to connect to a multisync  
monitor rather than a Sun monitor; a multisync monitor will be necessary in most situations, because most  
people who have Sun computers in their system have PCs as well. However, if your Sun monitor is capable of

SERVSWITCH™ MULTI  
3.3.4 CONNECTING NON-MULTISYNC MONITORS  
Most ServSwitch Multi applications that involve more than one hardware platform will require multisync  
monitors for all user stations, because PC, Mac, and Sun computers typically use sets of resolutions and refresh  
rates that differ greatly from one another. But if all of your computers are from the same platform, or if your  
platform-dedicated non-multisync monitor is nonetheless able to handle the video output of all your  
computers, we offer various adapters that will let you connect your monitor to the ServSwitch Multi. (Be aware  
that, in order to use a UICD’s on-screen display with a non-multisync monitor, you’ll probably have to change  
the display’s default synchronization. See Section 9.5.)  
To use a Mac monitor: Connect your user equipment as directed in Section 3.3.2, with this exception: Plug the  
HD15 male side of a KV16MAC adapter into the HD15 female end of the video strand of your KV27x0 cable,  
then plug the DB15 male end of your Mac monitor’s input cable into the adapter’s DB15 female side.  
To use a Sun monitor: Connect your user equipment as directed in Section 3.3.3, with this exception: Plug the  
HD15 male side of a KV16SUN adapter into the HD15 female end of the video strand of your KV28x0 cable,  
then plug the 13W3 male end of your Sun monitor’s input cable into the adapter’s 13W3 female side.  
To use an RS/6000 monitor with 13W3 connectors, an RS/6000 or other monitor with 3C3 connectors, an SGI monitor, or  
an HP or other monitor with three BNC connectors: Connect your user equipment as directed in Section 3.3.1, with  
this exception: Plug the HD15 male side of the appropriate adapter into the HD15 female end of the video  
strand of your KV25x5 cable, then plug the monitor cable into the adapter’s female side:  
• KV16RS6-1 for RS/6000 (HD15 M to 13W3 F);  
• KV163C3-1 for RS/6000 etc. (HD15 M to 3C3 F);  
• KV16SGI-1 for SGI (HD15 M to 13W3 F); or  
• KV16BNC for HP etc. (HD15 M to triple BNC F).

CHAPTER 3: Installing User-Interface Cards, User Cables, and Console Devices  
3.3.5 CONNECTING DUAL MONITORS (UICD ONLY)  
If your computer supports dual video outputs (dual monitors), you can use the User-Interface Card with On-  
Screen Display (UICD) to run video to the second monitor through the ServSwitch Multi. You must be logged  
on as the administrator (see Section 9.1.2) to configure this option (see Sections 9.3.1.A and 9.4.3.H). Here are  
the ServSwitch Multi components that you’ll need:  
• Two Autosensing CPU-Interface Cards (KV2000C), one to handle the computer’s primary video stream and  
one to handle the secondary video. These Cards must be installed side by side in the Switch chassis, with the  
Card that will be handling the secondary video having the higher address. For example, if the computer’s  
primary video output is going to a CPU Card installed in channel 1B, the CPU Card handling the secondary  
video must be installed in channel 1C. For directions on installing CPU-Interface Cards, see Section 4.3.  
• One User-Interface Card with On-Screen Display (KV2550C-R2) to send output to the primary monitor and  
one Universal User-Interface Card (UUIC, KV2500C) to send output to the secondary monitor. These two  
Cards don’t have to be next to each other, but they should be installed in the same Switch chassis. For  
directions on installing User-Interface Cards, see Section 3.2.  
• Two each of the appropriate Server Cables and User Cables for your platform and application.  
• If you’re running a PC type Server Cable (KV20xx or KV20xx-R2; see Section 4.4) between the computer’s  
secondary video output and the secondary CPU-Interface Card, you’ll also need a Loopback Mouse Adapter  
(product code KV16LOOP). This Adapter makes it possible for the ServSwitch Multi to recognize the  
secondary video connection as a valid CPU channel.  
Once you have the Cards and cabling installed, here’s how to make the dual monitor connections (refer to  
Figure 3-4 on the next page):  
1. Use your first Server Cable to connect your computer to the primary CPU-Interface Card as you would  
connect any other computer (see Section 4.4), but make sure you attach the Server Cable to the  
computer’s primary video-output port.  
2. Run your second Server Cable from the computer’s secondary video-output port to the second CPU-  
Interface Card: Attach the Cable’s HD44 male end to the Card’s HD44 female port, but at the computer  
end, attach only one strand of the Cable—the one that plugs into the secondary video port—to the  
computer. (If the cable is a KV20x0-R2 PC type, attach the Loopback Mouse Adapter to the mouse strand  
of this cable.)  
3. Run your first User Cable from your UICD to your primary monitor and other user equipment as you  
would connect any other user station (see the rest of Section 3.3).  
4. Run your second User Cable from your UUIC to the secondary monitor: Attach the Cable’s HD62 male  
end to the Card’s HD62 female port, then plug the secondary monitor’s video-input cable into the video  
strand at the other end of the cable; leave all of the other strands unattached.

Once you have all of the components of your entire ServSwitch Multi system installed, you will need to use the  
UICD to enable the dual-monitor setup. Here’s how to do so:  
1. If you haven’t yet added the dual-monitor computer to the Switch’s on-screen configuration records,  
follow the instructions for doing so in Section 9.3.1.A.  
If you have previously entered the computer into the on-screen configuration, follow the instructions  
for editing that computer’s record in Section 9.3.1.B.  
In either case, when you reach the “Dual Video” feature, press the space bar to enable it.  
2. Enter the Administrator-Controls Menu (see Section 9.4) and select the “System Configuration” option.  
Page down and highlight the “Dual Monitor Support Card Address” field (see Section 9.4.3.H). Enter the  
address of the UUIC that the secondary monitor is attached to. Until you enter a value in this field, dual-  
monitor support is still disabled regardless of what you did in step 1.

CHAPTER 4: Installing CPU-Interface Cards, Server Cables, and Computers  
4. Installing CPU-Interface Cards,  
Server Cables, and Computers  
IMPORTANT NOTE  
If you are installing a cascaded ServSwitch Multi system, you should make sure your  
Expansion Cards and Cables are installed properly before you begin installing other  
types of Cards or attaching devices to the system. Refer to Chapter 6 and (if your  
cascaded system includes any ServSwitch Multi Hubs) Chapter 7.  
Before you can connect your computers to your ServSwitch Multi system, you will need to configure and install  
Autosensing CPU-Interface Cards (our product code KV2000C) for each computer. These Cards have a set of  
jumpers that determine the type of video input from the computer (see Section 4.1) and an eight-position DIP  
switch that determines three other things: how the ServSwitch Multi handles the video signal and sync from that  
computer (see Section 4.2.1), how long that computer’s inactivity timeout is (see Section 4.2.2), and how the  
Switch maps certain keyboard keys if the computer is a Macintosh model (see Section 4.2.3).  
4.1 Setting the Jumpers to Configure the Video-Output Type  
If you hold an Autosensing CPU-Interface Card so that its HD44 connector is to the right, as shown in  
Figure 4-1, you will see a block of six jumpers labeled “JP1” through “JP6” in the lower right-hand corner of the  
Card’s circuit board. The settings of these jumpers determine what basic type of video signals the ServSwitch  
Multi should expect from the attached computer. The factory-default setting is for VGA/SVGA video. If the  
computer you’ll be attaching to any given CPU-Interface Card always outputs VGA/SVGA video, you don’t  
need to change the jumper settings for that Card.

CHAPTER 4: Installing CPU-Interface Cards, Server Cables, and Computers  
4.2 Setting the DIP Switch  
You can use the Autosensing CPU-Interface Card’s eight-position DIP switch to configure three different  
features: video-synchronization handling, keyboard/mouse timeout, and keyboard translation (mapping)  
options for Mac computers. Figure 4-3 shows this DIP switch, including the positions used to configure each  
feature and their default settings. Note that, even after you’ve installed the Card, you can change any of its DIP-  
switch settings from a console keyboard with a simple hotkey sequence; see Section 8.14. As you set each Card’s  
DIP switch, add this info to the Card’s record in the System-Configuration Chart (see Appendix A).

4.2.1 CONFIGURING VIDEO OPTIONS  
Your Autosensing CPU-Interface Card is factory-preset to pass the video signal from the attached computer  
through to any console that selects the computer’s channel. No changes are needed to DIP-switch positions 1  
through 3 unless (a) the CPU that will be attached to the Card does not output the standard video  
synchronization for its platform (separate horizontal and vertical sync for IBM PC compatible computers,  
composite sync for Apple or Sun computers), (b) not all of your console monitors will support the attached  
computer’s video sync(as will often be true for RS/6000, SGI, and HP machines that output sync on green), or  
(c) you want to fully disable the display of video signals from that computer (see the next paragraph).  
By default, a computer’s video will be displayed to users at any console that switches to the computer’s  
channel. By setting DIP-switch positions 1 through 3 all ON, you can disable the display of a computer’s video  
for security purposes, or if you are switching only keyboard and mouse through the ServSwitch Multi and  
handling video independently, or for any other reason.  
Table 4-1 shows the possible settings of DIP-switch positions 1 through 3. If you’re not sure what sort of  
synchronization a particular computer uses for its video output, consult the manual for the computer or its  
video card.

4.2.2 SETTING THE KEYBOARD/MOUSE-INACTIVITY TIMEOUT  
While multiple consoles can view a computer’s video at the same time, only one of them can have keyboard and  
mouse control over a computer at any given time. The amount of time that a console’s keyboard and mouse  
must be inactive before another console can take control is called the timeout. You can choose a 1-second  
timeout by setting DIP-switch position 4 to OFF; this is also the factory-default timeout setting. Alternatively, you  
can choose a 10-second timeout by setting DIP-switch position 4 to ON.  
4.2.3 SETTING THE KEYBOARD TRANSLATION (MAPPING) FOR MACINTOSH COMPUTERS  
When you have an Apple Macintosh compatible computer attached to the ServSwitch Multi through a CPU-  
Interface Card, any user with a PC keyboard who selects that Mac can turn on Scroll Lock to have the  
ServSwitch Multi remap (translate) some of the PC keys, so that they can perform Mac functions not normally  
accessible through the PC keyboard.  
In this mode (while Scroll Lock is ON), the Switch always maps the PC’s [F11] key to the Macintosh ᮤ  
(Power) key. If the PC keyboard is a Windows 104-/105-key type, it will also normally always try to remap the  
Windows Start key to the Mac (Command) key—but see the Caution notice below.  
Here’s where position 5 of the CPU-Interface Card’s DIP switch comes in: By default (position 5 set to OFF),  
the Switch also maps the PC’s [F12] key to the Mac (Command) key and the PC’s [Alt] key to the Mac  
[Option (Alt)] key. To use the PC’s [F12] key as the Mac [Option (Alt)] key and the PC’s [Alt] key as the  
Mac (Command) key instead, set DIP-switch position 5 to ON.  
While Scroll Lock is OFF, the PC keyboard’s [F11], [F12], and [Alt] keys function normally. For more  
information, see Section 8.4.  
CAUTION!  
This remapping is intended for input from older 101-/102-key keyboards that don’t  
have the Windows keys. If you use 104/105-key keyboards that include these keys in  
your ServSwitch Multi system, we recommend that you install UICDs for those  
consoles and enable the UICDs’ Remap WIN95 Keys option instead (see  
Section 9.4.3.E). Do not activate both types of remapping at the same time.

CHAPTER 4: Installing CPU-Interface Cards, Server Cables, and Computers  
4.3 Installing CPU-Interface Cards in a ServSwitch Multi  
To install an Autosensing CPU-Interface Card in a ServSwitch Multi, take these steps:  
1. Position the ServSwitch Multi so that its rear panel is facing you, as shown in Figure 4-4. Choose an  
available slot. In most cases, any slot that is covered with a blank (connectorless) panel will be available.  
However, note that on the Base Unit and MX, the local-console module on the far left end of the Switch’s  
rear panel is covered by a blank panel but is not an available slot; no ServSwitch Multi Card of any type can  
be installed in that slot. Remember that the option slot (the slot just to the right of the local-console  
module, which has no corresponding front-panel LED or pushbutton) is an available slot but should not  
be used to host a CPU-Interface Card except in systems with one user and 13 computers.

2. Once you’ve chosen the slot, write down the letter of the corresponding channel in the “Channel Letter”  
field of this Card’s record in a copy of the CPU-Interface Card pages of the System-Configuration Chart  
(see Appendix A). At this time you should also write down what appears on the Card’s label (just to the  
right of the HD44 connector if you look at the connector from the rear) in the Chart’s “Card-Label  
Information” field, and (if the ServSwitch Multi unit is part of a cascaded system) you should write down  
the Switch’s address in the “Switch Address” field as well.  
3. Remove the panel covering the available slot by unscrewing the two Phillips-head screws that hold it in  
place. (Save these screws; you’ll be replacing them momentarily.)  
4. If you look into the open slot on the Switch, you will see “guide tracks” that the top and bottom of the  
Card should slide along when you install it. Slide the Card gently into the slot along these tracks, until the  
Card’s HD44 connector lines up flush with the back of the unit, as shown in Figure 4-5.  
Figure 4-5. Inserting a CPU-Interface Card in the Switch.  
5. Secure the Card in the Switch with the screws you removed in step 3. Retighten the screws completely, but  
do not overtighten them.  
Repeat the above procedure for every Autosensing CPU-Interface Card in your system.

CHAPTER 4: Installing CPU-Interface Cards, Server Cables, and Computers  
4.4 Connecting the Server Cables and Computer Equipment  
Server Cables connect your computers to the ServSwitch Multi. You will need a set for each computer in your  
system. These cables are 8 feet (2.4 m), 20 feet (6.1 m), or 30 feet (9.1 m) long and have an HD44 (high-density  
44-pin D-subminiature) male connector on one end. They have different numbers of connectors on the other  
end, depending on the options you ordered (see Table 4-2 below and the corresponding subsections on the  
following pages). In order to connect RS/6000 or SGI workstations, you’ll also need a special adapter; see  
®
Section 4.4.4. (It is also possible to connect HP workstations; please call Black Box Technical Support if you  
need to do this.)  
Things to be aware of when you make Server-Cable connections of any type:  
• As you attach the console equipment to each CPU-Interface Card, finish filling out the Card’s record in the  
System-Configuration Chart (see Appendix A).  
• The Cable’s audio-strand connectors are very similar to each other, but the audio-in strand has a blue band  
around it so that you can tell the two apart.  
• Similarly, on some versions of the Cable, the mouse-port-strand connector is the same as the connector on  
the keyboard-port strand or serial-port strand. On these Cable versions, the mouse-port strand has a yellow  
band around it so you can tell it apart.  
• Some speakers, headphones, and microphones have plugs and jacks different from the type that the  
ServSwitch Multi’s audio cables are designed for. If this is the situation with your audio equipment, you will  
need adapters to connect your equipment to the ServSwitch Multi system. These adapters are commonly  
available; call your local electronics-supply store for more information.  
• For serial connections, if you want to connect an Apple serial port or a serial port with a connector other  
than a DB9 female, see Appendix E.

To install your cable and computer at each chosen computer channel, first plug the Server Cable’s HD44  
connector into the matching connector on the CPU-Interface Card. When you’re sure the connection is firmly  
seated, secure it by tightening the associated thumbscrews.  
Now power down the computer and plug the matching connectors at the end of the universal IBM style  
Server Cable’s video-port, keyboard-port, and mouse-port strands into the appropriate ports on your PC: If it’s a  
PC/AT compatible, use the 5-pin DIN PC/AT keyboard connector and the DB9 female serial mouse-port  
connector; if it’s a PS/2, use the 6-pin mini-DIN PS/2 keyboard and mouse connectors. If the Server Cable is an  
audio type, it will have three additional connectors: two RCA plugs for a mono audio input and stereo output,  
and a DB9 female connector to attach to another serial port. Attach these to any appropriate audio or serial  
ports or equipment as desired.

you’ll need will be labeled KV2920, KV2925, etc., instead of KV2220, KV2225, etc. (see Table 4-2). Rather than a  
DB15 male connector as shown above, the cable will have an HD15 male VGA connector as shown in  
Section 4.4.1. (Otherwise, the two types of cable are identical.)  
To install your cable and computer at each chosen computer channel, first plug the Server Cable’s HD44  
connector into the matching connector on the CPU-Interface Card. When you’re sure the connection is firmly  
seated, secure it by tightening the associated thumbscrews.

CHAPTER 4: Installing CPU-Interface Cards, Server Cables, and Computers  
4.4.4 FOR RS/6000 AND SGI COMPATIBLE COMPUTERS  
If on a given channel you are using an RS/6000 compatible workstation computer that supports standard VGA  
video, use the same equipment and procedures as you would to install a PS/2 compatible machine—see  
Section 4.4.1.  
If you are using an RS/6000 compatible workstation that outputs its video on 13W3 or 3C3 connectors, or if  
you are using an SGI (Silicon Graphics) compatible workstation, connect your computer equipment as directed  
in Section 4.4.1, with this exception: Plug the male side of the appropriate adapter into the workstation’s video  
port, then plug the video strand of your KV20x0 cable into the adapter’s HD15 female side:  
• KV16RS6-2 for RS/6000 (HD15 F to 13W3 M);  
• KV163C3-2 for RS/6000 etc. (HD15 F to 3C3 M); or  
• KV16SGI-2 for SGI (HD15 F to 13W3 F).  
If the workstation outputs sync on green (as will always be the case if it has a 3C3 video port), and your  
monitors do not all support sync on green, be sure to set positions 1 through 3 of the CPU-Interface Card’s DIP  
switch to OFF OFF ON, the setting that causes the Card to generate horizontal and vertical sync from sync on  
green (see Section 4.2).  
Be aware that, in order to use a UICD’s on-screen display with a non-multisync monitor, you’ll probably have  
to change the display’s default synchronization. See Section 9.5.

SERVSWITCH™ MULTI  
5. Installing Management and  
Serial Control Cards and  
Associated Equipment  
IMPORTANT NOTE  
If you are installing a cascaded ServSwitch Multi system, you should make sure your  
Expansion Cards and Cables are installed properly before you begin installing other  
types of Cards or attaching devices to the system. Refer to Chapter 6 and (if your  
cascaded system includes any ServSwitch Multi Hubs) Chapter 7.  
5.1 Overview of the Cards  
The Management Card (our product code KV1608C-R2) and the Serial Control Card (our product code  
KV1609C) work together to enable you to connect terminal-based file servers, network hubs, routers, and other  
serial server-room equipment to the ServSwitch Multi and control them using one keyboard, monitor, and  
mouse. This “terminal switching” requires at least one Management Card and one Serial Control Card in the  
system. The Management Card provides the menuing and advanced control features. Serial Control Cards  
provide four ports each for attaching equipment to the ServSwitch Multi system. From your Management Card,  
you may select any terminal in the system, regardless of which Serial Control Card it is attached to.  
The Management Card functions similarly to an CPU-Interface Card (KV2000C) in that you switch directly to  
it from your keyboard or with the ServSwitch Multi’s on-screen menus or front-panel pushbuttons. Once you’ve  
switched to the Management Card, on-screen menus allow you to name and select the attached terminals in  
your ServSwitch Multi system. You can also configure data rate, data bits, stop bits, parity, and flow control for  
each terminal through the menus.  
The Management Card has an onboard microprocessor that handles the Card’s “Security-Monitoring System”  
and “System-Management Tools.” With the Security-Monitoring System, administrators can track all switching  
activity through a simple on-screen menu. Immediate feedback on logging and switching history is available for  
every system user. With the System Management Tools, network managers can display their ServSwitch Multi  
system configurations for easy troubleshooting. This menu-driven system shows the type of Card installed in  
each port and the current firmware and hardware revision of each. Information on the type of computer  
attached to each CPU-Interface Card is also available.  
The Management and Serial Control Cards are field-installable and Flash-upgradable. Cards can be added or  
replaced without disassembling or powering down the system. This makes installation, configuration, and  
maintenance much easier.

CHAPTER 5: Installing Management and Serial Control Cards and Associated Equipment  
5.2 The Cards and Cables Illustrated  
The Management Card and Serial Control Card are shown in Figure 5-1. The Management Card has a DB9  
male connector that functions as an EIA/TIA RS-232 serial interface (pinned out according to TIA-574, like the  
serial ports of an IBM PC/AT or PS/2 computer) so that you can upload security logs from the Card (see  
Section 10.4.7) or download firmware upgrades to the Card (see Section 10.4.4).  
The Serial Control Card has four RJ-45 female connectors. These function as proprietarily pinned EIA/TIA  
RS-232 serial interfaces for connection to, and communication with, your servers, hubs, routers, etc.

Figure 5-2 shows the cables you’ll attach to these Cards. You can run a PC/AT (DB9) null-modem cable from  
the Management Card to a PC running a terminal emulator.  
You can run a Category 5 twisted-pair patch cable from any port on the Serial Control Card to the serial ports  
on your equipment. (Connecting this cable to your equipment will require a modular adapter; see Section 5.4.)

5.3 Installing the Cards  
To install a Management Card or Serial Control Card in a ServSwitch Multi, take these steps:  
1. Position the ServSwitch Multi so that its rear panel is facing you, as shown in Figure 3-3 in Section 3.2.  
Choose an available slot. In most cases, any slot that is covered with a blank (connectorless) panel will be  
available. However, note that on the Base Unit and MX, the local-console module on the far left end of the  
Switch’s rear panel is covered by a blank panel but is not an available slot; no ServSwitch Multi Card of any  
type can be installed in that slot. Remember that the option slot (the slot just to the right of the local-  
console module, which has no corresponding front-panel LED or pushbutton) is an available slot and can  
host any card other than a CPU-Interface Card.  
2. Once you’ve chosen the slot, write down the letter of the corresponding channel in the “Channel Letter”  
field of this Card’s record in a copy of the Management/Control Cards pages of the System-Configuration  
Chart (see Appendix A). At this time you should also write down what appears on the Card’s label (just to  
the right of the DB9 connector or RJ-45 connectors if you look at them from the rear) in the Chart’s  
“Card-Label Information” field, and (if the ServSwitch Multi unit is part of a cascaded system) you should  
write down the Switch’s address in the “Switch Address” field as well.  
3. Remove the panel covering the available slot by unscrewing the two Phillips-head screws that hold it in  
place. (Save these screws; you’ll be replacing them momentarily.)  
4. If you look into the open slot on the Switch, you will see “guide tracks” that the top and bottom of the  
Card should slide along when you install it. Slide the new Management Card or Serial Control Card gently  
into the slot along these tracks, until the Card’s connector or connectors line up flush with the back of the  
unit, as shown in Figure 5-3.  
Figure 5-3. Inserting a Card in the Switch (Management Card shown at left, Serial Control Card shown at right).  
5. Secure the Card in the Switch with the screws you removed in step 3. Retighten the screws completely, but  
do not overtighten them.  
Repeat the above procedure for every Management Card or Serial Control Card in your system.

CHAPTER 5: Installing Management and Serial Control Cards and Associated Equipment  
5.4 Attaching Terminals to the Serial Control Card  
The Serial Control Card has four ports available for attaching terminals, hubs, routers, and other serial  
equipment. To attach your devices to these ports, you will need:  
• Category 5 UTP cables. We provide these cables, terminated with RJ-45 plugs, in many stock lengths from  
1 to 100 feet (0.3 to 30.5 m) and in just about any custom length you might want.  
• Modular adapters to patch the RJ-45 plugs to your devices. We have these types available:

designed to be connected to DTE devices such as PCs, terminals, etc. Adapters pinned as DTE are designed  
to be connected to DCE devices such as modems and most bridges and routers.  
To attach a serial device to the ServSwitch Multi system, take these steps:  
1. Attach the appropriate adapter to the serial port of your device.  
2. Plug one end of your CAT5 cable into the RJ-45 socket on the adapter.  
3. Plug the other end of the cable into the first available port on the rear of your Serial Control Card.  
Repeat steps 1 through 3 for each device you want to connect to the Serial Control Card.  
Once you have finished installing these Cards and their cabling and attached devices, and have familiarized  
yourself with the general operation of the ServSwitch Multi itself as described in Chapter 8, you can proceed  
with operating the Cards and attached devices as described in Chapter 10.

SERVSWITCH™ MULTI  
6. Planning and Installing an  
Expanded System (Optional)  
If you are going to be setting up a keyboard/video/mouse-switching system that involves interconnecting  
multiple ServSwitch Multi units, you should follow the instructions in this chapter to design the layout of this  
system and install your Switch-to-Switch links (including Expansion Cards and expansion cables) before you  
install any Interface, Management, or Serial Cards in, or attach any computer or peripheral equipment to, any  
individual Switch.  
This chapter will focus on the basic principles of ServSwitch Multi expansion, on installing expansion  
hardware, and on possible designs for expanded layouts that involve only the ServSwitch Multi EXP and SB  
(and, if absolutely necessary, the Base Unit and MX). For information about the ServSwitch Multi Hub  
(including how to install it and its modules) and on designs for expanded layouts including the Hub, refer to  
Chapter 7.  
CAUTION!  
Systems involving a large number of ServSwitch Multi units can be very tricky to set  
up, and if they are wrongly configured, it can be difficult to figure out where the  
problem is. Read this chapter carefully; if there’s anything you’re not clear about or  
not confident about, please call Black Box Technical Support before you proceed, and  
consult with our technicians for added assurance that your configuration will be  
correct the first time.  
To expand your ServSwitch Multi system beyond the confines of a single unit, you will need to add Expansion  
Transmit and Receive Cards to your system. Connecting a Transmit Card in one Switch to a Receive Card in  
another melds those two Switches into one larger switching matrix; see Figure 6-1 on the next page. If you  
install Transmit Cards in the same ServSwitch Multi as a set of computers, those computers can communicate  
with consoles (user stations) attached to other Switches. Conversely, if you install Receive Cards in the same  
ServSwitch Multi as one or more consoles, those consoles can communicate with computers attached to other  
Switches. Regardless of whether or not any Expansion Cards are installed in a ServSwitch Multi, the console(s)  
attached to that unit can always access any computer attached to the same unit.  
You will use one or more Expansion Cables to connect your Transmit Cards to your Receive Cards. Each of  
these cables can be up to 250 feet (76.2 m) long (although total cable length between a console and a  
computer can’t be more than 500 ft. [152.4 m]). Two ports are available on each Transmit and Receive Card for  
Expansion-Cable connections.  
Refer to Section 2.6.4 for descriptions and illustrations of the ServSwitch Multi EXP and the Expansion Cards  
and Cables.

Figure 6-1. A two-unit ServSwitch Multi system.  
To successfully configure and install your expanded ServSwitch Multi system, you will need to figure out all of  
these things:  
1. Where to put your ServSwitch Multi units and how to interconnect them (see Section 6.1—also Chapter 7  
if your system includes any ServSwitch Multi Hub).  
2. How you are going to distribute your Expansion Cards and your computers, console equipment, serial  
control devices, and associated Interface, Serial Control, and Management Cards among the Switches (see  
Section 6.2).  
3. What addresses and distance you’re going to configure your Expansion Cards for, and how you will do this  
(see Section 6.3).  
4. How to install your Expansion Cards (see Section 6.4) and Cables (see Section 6.5) and visually inspect  
your system-in-progress (see Section 6.6).  
5. Lastly, of course, how to install your User-Interface Cards (see Chapter 3), your CPU-Interface Cards (see  
Chapter 4), and, if any, your Management and Serial Cards (see Chapter 5).

SERVSWITCH™ MULTI  
6.1 Placing the ServSwitch Multi  
NOTE  
Here and elsewhere in this chapter you will see diagrams in which ServSwitch Multis  
units are identified as “Switch 0.” You will notice that all such Switches have Receive  
Cards installed in them, but no Transmit Cards. Do not set the address of any unit with  
a Transmit Card installed in it to zero; your system will not work. The address zero is  
reserved as the operating address for all ServSwitch Multis in which no Transmit  
Cards are installed—unless a firmware upgrade has to be done (see Section 8.13 and  
the entry for “CHASSIS=n” in Section 8.15).  
There are two basic types of expansion configurations for the ServSwitch Multi: the “star” and the “daisychain.”  
In the star configuration, additional Switches are all attached to a central “hub” ServSwitch Multi, as shown in  
Figure 6-2. In the daisychain configuration, additional Switches are attached in a line: The first Switch is  
connected to the second, which in turn is connected to the third, and so on, as shown in Figure 6-3. (Note that  
in both Figure 6-2 and Figure 6-3, the users on Switch 0 can access any computer attached to any of the four  
Switches in the system.) The star configuration is the more common of these two approaches and is the  
recommended setup for most applications.

CHAPTER 6: Planning and Installing an Expanded System (Optional)  
For systems that (a) will have to reach more than sixty computers or (b) can’t be efficiently laid out in a straight  
line but will be operating across computer-to-console distances greater than 250 feet (76.2 m), we recommend a  
combination star/daisychain configuration, as shown in Figure 6-4. This combination is usually the most  
flexible way to manage large numbers of computers, especially if you will be frequently adding, moving, or  
removing them.

Figure 6-4. A hybrid expanded configuration.  
As you configure your own system, keep the following considerations in mind:  
1. The maximum cabling distance between any user and any accessible computer in the system is 500 feet  
(152.4 m). If this maximum distance is exceeded, video quality will be severely degraded.  
2. The maximum number of ServSwitch Multis between any user and any accessible computer is four,  
including the Switches attached to the user’s console and the computer. If a user attempts to switch to a  
computer more than four Switches away (that is, a computer that would have to send its video signal  
through more than four Switches to reach the user), the command will be ignored; the system will remain  
on the current channel until the user selects a closer channel.

SERVSWITCH™ MULTI  
6.2 Determining Where to Install Cards and Attach Equipment  
Once you’ve chosen the best placements and system configuration for your ServSwitch Multis, you’ll need to  
determine (a) which Expansion Cards to install in which Switches, (b) where to put your computers and user  
equipment (which will determine where you install your CPU and User-Interface Cards), and (c) where to put  
your terminals, routers, etc. if you’re connecting any to the system (which will determine where you install your  
Management and Serial Control Cards).  
As you plan, here’s what you need to keep in mind about how the Expansion Cards work:  
1. In order for a computer attached to a ServSwitch Multi to transmit its video signal to consoles attached to  
other Switches in the system, you must install at least one Transmit Card in the computer’s Switch. Refer to  
Figure 6-5.  
2. In order for a console attached to a ServSwitch Multi to receive signals from computers attached to other  
Switches in the system, you must install at least one Receive Card in the console’s Switch. Refer to  
Figure 6-5.  
In this example, users on Switch 2 have

access to the local computers (the ones

Users on Switch 1 can not only access the

cannot reach the computers on Switch 0  
because no Transmit Card is installed in  
Switch 0.

3. There are several independent data pathways available to carry transmissions through any ServSwitch  
Multi: eight pathways for the SB model, four pathways for the EXP and Base Unit models, and only two for  
the MX model. Each expansion-port link between two ServSwitch Multis through a pair of Transmit and  
Receive Cards is going to require the use of one of these pathways through each of the two Switches every  
time signals are transmitted across the link. Whenever all of the pathways in a given Switch are active  
(carrying data) at the same time, any attempt by any other user in the system to independently select a  
computer channel on that Switch will be ignored.  
Refer to Figure 6-6; let’s examine what happens if all of these Switches are ServSwitch Multi EXPs. Say  
the user on Switch 0 wants to access computer 1H. A Transmit Card on Switch 1 is connected to a Receive  
Card on Switch 0, so this would work if there were fewer users on Switch 1. But because there are four  
users on Switch 1, and all of them will be using at least one of Switch 1’s data pathways at all times, Switch 1  
has no available pathways left. Therefore the user on Switch 0 can’t establish an independent connection  
to computer 1H (although he or she can share access to that computer—see Section 8.3.) However, as  
long as the user on Switch 2 has computer 2B selected, the user on Switch 0 can access computer 2K  
independently, because the user on Switch 2 is only occupying one of the four pathways through Switch 2.  
If all of the switches in Figure 6-6 are ServSwitch Multi SBs, the user on Switch 0 has no problem  
independently accessing computer 1H. This connection would only be the fifth for Switch 1, which would  
still have three free data pathways available.

SERVSWITCH™ MULTI  
6.3 Configuring Your Expansion Cards  
You will need to configure your Transmit and Receive Cards before you install them in your ServSwitch Multi  
system. There are two steps to this process:  
1. Setting the DIP switch on each Transmit Card for the proper ServSwitch Multi unit address.  
2. Setting the jumpers on each Transmit and Receive Card for the length of Expansion Cable that will be  
attached to each of the Card’s two ports.  
6.3.1 SETTING THE TRANSMIT CARD’S UNIT-ADDRESS DIP SWITCH  
All ServSwitch Multis that contain Transmit Cards must be given a unique unit address that you determine. Unit  
addresses are numeric, and may be any value from 1 to 254 (addresses “0” and “255” are reserved). Make sure  
to set every Transmit Card that you’ll be installing in a given ServSwitch Multi to the same unit address; if a  
Switch detects that it contains Transmit Cards with different addresses, it will not operate at all. Make very sure  
not to set Transmit Cards installed in different Switch units to the same address; otherwise your system will  
operate, but it will malfunction, and finding and fixing the problem could be tough.  
To set the unit-address DIP switch on your Transmit Cards, take these steps:  
1. Gather together all of the Transmit Cards that you will be installing in a particular ServSwitch Multi.  
2. Orient your first Transmit Card as shown in Figure 6-7, and find its colored DIP-switch assembly.

same address.  
5. Set these Transmit Cards beside their ServSwitch Multi unit. Gather together all of the Transmit Cards that  
will be installed in the next ServSwitch Multi unit, and repeat steps 2 through 5 until you have reached the  
last ServSwitch Multi unit in your system.

SERVSWITCH™ MULTI  
6.3.2 SETTING THE DISTANCE JUMPERS ON THE TRANSMIT AND RECEIVE CARDS  
Every pair of Transmit and Receive Cards that will be communicating with each other through one of their  
ports must be configured for the length of the Expansion Cable(s) that will connect them together. This  
involves setting a series of “distance jumpers” for each port on each card. (Remember that, should you decide  
to connect the two ports of an Transmit Card to ports on two different Receive Cards, or vice versa, you will  
need to set the ports’ jumpers differently.)  
Take these steps for each such pairing of Transmit and Receive Cards in your system:  
1. Orient a pair of Transmit and Receive Cards as shown in Figure 6-8. (Because of the way its components  
are labeled, it’s easier to read the regular Receive Card if you hold it with its port connectors to the left.)  
Expansion Transmit Cards  
Expansion Receive Cards  
Figure 6-8. Expansion-card orientation.  
2. Choose which port on the Transmit and Receive Cards you will be connecting your Expansion Cable(s) to:  
the lower one (#1) or the upper one (#2). You may use either, but if you choose Port 1 on one Card, the  
cable(s) attached to it must run to Port 1 on the other Card; likewise Port 2 must be connected to the  
other Card’s Port 2.  
3. Referring to Tables 6-2 through 6-4 on the next two pages, set the appropriate jumpers on each Card  
according to the port chosen and the length of the Expansion Cable that will connect them. As you  
configure each Card, fill out a record for it on a copy of the Transmit- or Receive-Card System-  
Configuration Chart (Chart A-3 or A-4 respectively in Appendix A).  
After all of the Cards have been configured, they are ready to be installed. Follow the directions for doing this  
in Section 6.4.

6.4 Installing Your Expansion Cards  
To install a Transmit or Receive Expansion Card in a ServSwitch Multi Base Unit or Expansion Chassis, take  
these steps:  
1. Position the ServSwitch Multi so that its rear panel is facing you, as shown in Figure 3-3 in Section 3.2.  
(While the Base Unit, MX, EXP, and SB models are all shown in that illustration, we recommend that  
where possible you use only EXP and SB units in cascaded ServSwitch Multi systems.)  
2. Choose an available slot. In most cases, any slot that is covered with a blank (connectorless) panel will be  
available. However, note that on the Base Unit and MX (if you must use any of these), the local-console  
module on the far left end of the Switch’s rear panel is covered by a blank panel but is not an available  
slot; no ServSwitch Multi Card of any type can be installed in that slot. Remember that the option slot (the  
slot just to the right of the local-console module, which has no corresponding front-panel LED or  
pushbutton) is an available slot and should preferably host an Expansion Card, User-Interface Card, etc.,  
rather than a CPU-Interface Card.  
3. Remove the blank panel covering the available slot by unscrewing the two Phillips-head screws that hold  
the panel in place.  
4. Find the two Phillips-head screws on the Transmit or Receive Card, located above and below the two  
connectors. Back these screws out slightly until they are flush with the Card’s cover plate.  
5. If you look into the open slot on the Switch, you will see “guide tracks” that the top and bottom of the  
Card should slide along when you install it. Slide the Card gently into the slot along these tracks, until the  
Card’s two HD26 connectors or six RJ-45 connectors line up flush with the back of the unit, as shown in  
Figure 6-9.  
Figure 6-9. Inserting a regular (left) or CAT5 (right) Expansion Card.  
6. Retighten the holding screws completely. Do not overtighten.  
Repeat the above procedure for every Transmit Card and Receive Card in your system.

CHAPTER 6: Planning and Installing an Expanded System (Optional)  
6.5 Installing Your Expansion Cables  
To connect your Expansion Cables to the Expansion Cards, take these steps:  
1. Get Expansion Cable(s) whose length matches the jumper settings of the chosen port on your first  
communicating pair of Transmit and Receive Cards.  
2A. Regular Expansion Cards: Connect the Expansion Cable’s single female HD26 connector to the chosen port  
(male HD26 connector) on the Transmit Card. Run the cable to the matching port on the Receive Card.  
Tighten the thumbscrews on the connectors at each end of the cable.  
2B. CAT5 Expansion Cards: Connect the RJ-45 plugs of your three Expansion Cables to the chosen port (three  
RJ-45 sockets) on the Transmit Card. Run the cables to the matching port on the Receive Card.  
Repeat the above procedure for every communicating pair of ports in your system.  
6.6 Inspecting Your Expanded System  
You can find out whether or not your Expansion Cards and Cables are properly installed by observing the LEDs  
on the front panels of the ServSwitch Multis that you’ve installed the Cards in. One by one, plug the ServSwitch  
Multi units in and turn them on long enough to look at their front panels.  
On a ServSwitch Multi EXP, an Expansion Card is installed correctly in a given channel, and the cabling  
(single Cable for regular Cards, three Cables for CAT5 Cards) is installed correctly on that Card’s Port 2, when  
that channel’s upper (amber) LED is lit. The Card is OK, and the cabling is installed correctly on that Card’s  
Port 1, when that channel’s lower (green) LED is lit. However, if you’ve installed Transmit Cards with  
conflicting unit addresses in the same ServSwitch Multi EXP, the amber and green LEDs for the Transmit  
Cards’ channels will flash back and forth.  
On a ServSwitch Multi Base Unit, an Expansion Card is installed correctly in a given channel, and the cabling  
(single Cable for regular Cards, three Cables for CAT5 Cards) is installed correctly on either of that Card’s  
ports, if that channel’s green LED is lit. Similarly to the EXP, if you have Transmit Cards in the same Base Unit  
with conflicting unit addresses, the green LEDs for the Transmit Cards’ channels will flash.  
(For more information about the operating functions of the LEDs, see Section 8.1.)  
If everything looks good, proceed with the steps called for in Chapters 3 through 5. If you have problems  
installing or operating your cascaded ServSwitch Multi system, see Section 11.1.

7. The ServSwitch Multi Hub  
7.1 Overview  
The ServSwitch Multi Hub is designed to make configuring and installing large, complex cascaded ServSwitch  
Multi systems as efficient and economical as possible. By channeling the expansion signals that pass between  
other ServSwitch Multi units through a “central switching station,” the Hub streamlines your configuration and  
can greatly reduce the number of ServSwitch Multi units, Expansion Transmit and Receive Cards, and  
expansion cables in the system.  
Figure 7-1 shows a simple 16 x 16 matrix of 4-User units configured with and without the Hub. All users in  
this system can access any computer at any time.  
Using only ServSwitch  
Multi EXP units, connecting  
16 users to 16 computers  
so that all of the users have  
independent access to all  
of the computers requires  
eight EXPs, 32 CAT5  
Transmit Cards, 32 CAT5  
Receive Cards, and  
128 CAT5 expansion  
cables. In this picture, each  
of the lines between the  
EXP units represents eight  
cables.  
If you use a Hub with one  
Transmit Module and one  
Receive Module installed,  
you’ll still need eight EXP  
units, but only eight CAT5  
Transmit Cards, eight CAT5  
Receive Cards, and  
64 expansion cables—  
a significant savings. In this  
picture, each line between  
the EXP units and the Hub  
represents four cables.

CHAPTER 7: The ServSwitch Multi Hub  
The Hub, shown in Figure 7-2, is a rackmountable chassis that’s 9U (15.75", 40 cm) high. It contains two power  
supplies, two fan assemblies, and as many as nine total Transmit Modules and Receive Modules. The power  
supplies are fully redundant and hot-swappable, so you can replace one at any time without powering down the  
system. Fan assemblies are also hot-swappable, but both are needed to cool a fully loaded Hub chassis.  
Each Transmit or Receive Module contains 16 pairs of RJ-45 female connectors. One RJ-45 of each pair  
accepts the Category 5 video cable from the video (bottom) RJ-45 connector of an expansion port on a CAT5  
Expansion Card installed in a ServSwitch Multi EXP, SB, Base Unit, or MX. The other RJ-45 of each pair accepts  
the Category 5 keyboard/mouse cable from the same expansion port’s keyboard/mouse (middle) RJ-45  
connector. (The ServSwitch Multi Hub doesn’t support connections involving the multimedia [serial and audio,  
top] RJ-45 connector of these expansion ports; ServSwitch Multi systems that use Hubs carry keyboard, video,  
and mouse signals only.)

SERVSWITCH™ MULTI  
7.2 Features and Benefits  
• Liquid crystal display. The Hub has a front-panel LCD for easy configuration and identification. You can  
see system-connection information, check the hardware and firmware revisions of your modules, or  
troubleshoot system errors, all from an easy-to-use set of screens.  
• Front-panel LEDs. LEDs on the Hub ’s front panel let you monitor system power and error status at a  
glance. The green Power LED will remain continuously lit while the Hub is receiving AC power from either  
of its power supplies. The red Fail LED blinks when a problem is detected, then becomes solidly lit when  
the problem is acknowledged. The LED will remain lit until the problem is resolved, or begin blinking  
again if a new problem is discovered.  
• Flash upgrade capability. The Hub’s Modules, including the Front-Panel Element that controls the  
components mounted on its front panel, are Flash-upgradable. Flash-memory technology allows you to  
upgrade the Modules’ firmware without removing Modules or powering down the system. New firmware  
revisions can be uploaded into the Modules through serial connections to other ServSwitch Multi models in  
your system (see Section 8.13).  
• Hot-swappable components. The power supplies, fan assemblies, and the Transmit/Receive Modules in the  
Hub are all hot swappable. You can remove or replace these components without powering down the  
system or the attached servers, so maintenance can be performed at any time without interrupting system  
users.  
7.3 Installing the Hub  
Take these steps to install a ServSwitch Multi Hub:  
1. First—before you do anything else—plan your layout. You’ll want to connect each of the two ports on each  
of the CAT5 Transmit and Receive Cards in your ServSwitch Multi system to one of the ports on a Hub’s  
Receive or Transmit Module respectively. Refer to the sample layouts in Section 7.7. If you still have any  
questions, please call Black Box Technical Support. (We strongly encourage you to call Black Box Tech  
Support anyway, to discuss your application, before you perform any large or complex ServSwitch Multi  
installation.)  
2. When you have your physical installation planned out, install the Hub’s fan assemblies and power supplies  
in its chassis (these are shipped uninstalled to minimize the risk of them being damaged in transit):  
a. Make sure that the power supplies are not connected to any AC outlet and that their power switches are  
in the “OFF” position.  
b. Gently slide the power supplies into their mounting brackets on the left side of the Hub. (It doesn’t  
matter which supply you put in which bracket.)  
c. Connect a power cord to the IEC 320 inlet on each of the power supplies. Plug the other end of each  
power cord into a working AC outlet. Switch on both of the power supplies and verify that the fan  
modules work—the fans should start running right away.

CHAPTER 7: The ServSwitch Multi Hub  
NOTE  
If it will be easier for you to configure your Modules while you’re looking at cables  
you’ve already installed, feel free to attach your expansion cables to any given Module  
(refer to step 6) before you do steps 3 through 5.  
3. Next you will need to configure the DIP switches on your Transmit Modules. Each of these Modules has  
sixteen dual-RJ-45 Transmit ports on it, numbered 1 through 16 from left to right, as shown in Figure 7-5  
on the next page. Each port has three six-position DIP switches that you need to set for the length of the  
Category 5 cable that will be attached to the port. The locations of these DIP switches are shown in  
Figure 7-3 below, and their possible settings are shown in Figure 7-4 on the next page. For any given  
Transmit port, leave all of the switch positions set to OFF if the cable you’ll be attaching to that port isn’t  
more than 25 ft. (7.6 m) long. If the cable is longer, move a position of each switch to ON for each 50 ft.  
(15.2 m) longer, starting with the leftmost position and working toward the right. For example, set the  
leftmost position ON if the cable is between 25 and 75 ft. (7.6 and 22.9 m) long; set the two leftmost  
positions ON if the cable is between 75 and 125 ft. (22.9 and 38.1 m) long; and so on, up to a maximum of  
250 ft. (76.2 m), which is the greatest length of CAT5 expansion cable that the ServSwitch Multi system can  
support.

4. Now configure the DIP switches on your Receive Modules. Like the Transmit Modules, each of the Receive  
Modules has sixteen dual-RJ-45 transmit ports on it, numbered 1 through 16 from left to right, as shown in  
Figure 7-5 on the previous page. Each port has three two-position DIP switches that you need to set for the  
length of the Category 5 cable that will be attached to the port. The locations of these DIP switches are  
shown in Figure 7-6, and their possible settings are shown in Figure 7-7. For any given Receive port, leave  
all of the switch positions set to OFF if the cable you’ll be attaching to that port isn’t more than 125 ft.  
(38.1 m) long. If the cable is longer than 125 ft. (38.1 m) but not more than 225 ft. (68.6 m), move the left-  
hand position in each switch to ON. If the cable is longer than 225 ft. (68.6 m), up to the Switch’s  
maximum supported CAT5 expansion-cable length of 250 ft. (76.2 m), move all of the switch positions to  
ON.

5. Remove the blanking plates on the Hub’s rear panel that cover the slots you want to install your Transmit  
and Receive Modules in. Gently slide your Modules into the Hub’s chassis and tighten the retaining screws.  
6. Use the Hub’s LCD to set the Hub’s chassis number. When you turned ON the Hub’s power supplies in  
step 2, the Idle Display screen (refer to Section 7.5.1) should have appeared on its LCD panel. Press the  
Down button on the Hub’s front panel to get from this screen to the Chassis ID screen (refer to  
Section 7.5.3). To set a new Hub’s ID (or to change the ID of a Hub you’ve moved to a new system or  
location), press the Hub’s Enter button. This screen will appear:  
Chassis ID  
->new ID ###  
old ID ###  
****EDIT MODE****  
The existing ID number is shown next to “old ID”; a new Hub will have the factory-default ID number 0.  
This is not a valid ID; you need to change it to another number—different from that of any other Switch chassis in your  
system—immediately. Press the Hub’s Up and Down buttons to set a new chassis ID for your Hub (the display  
will scroll through the possible numbers from 1 to 254). When you’re done, press the Hub’s Enter button  
to save the changes and return to the Chassis ID Menu, or press the Hub’s Escape button to cancel your  
changes and return to the Chassis ID screen without saving them. If neither button is pressed within  
5 seconds of your last change, your changes will be canceled and you will automatically be returned to the  
Chassis ID screen.  
7. Lastly, referring to the layout you should have planned in step 1, run Category 5 cables between the ports  
on your Hub’s Transmit and Receive Modules and the ports on the CAT5 Expansion Cards in the other  
ServSwitch Multis in your system. For each Module port/Card port pair that you want to interconnect, one  
cable should connect the Module port’s video connector (the upper of its two RJ-45s) with the Card port’s  
video connector (the lowest of its three RJ-45s); a second cable should connect the Module port’s  
keyboard/mouse connector (the lower of its two RJ-45s) with the Card port’s keyboard/mouse connector  
(the middle of its three RJ-45s). Don’t make any connections to the Card port’s multimedia (serial/audio)  
connector (the uppermost of its three RJ-45s); the Hub doesn’t carry multimedia signals.  
The ServSwitch Multi Hub should now be ready for continuous operation, as soon as you update the  
configuration of the rest of your ServSwitch Multi system.  
7.4 The Functions of the Hub’s LEDs  
There are two LEDs on the Hub’s front panel, one green and one red. The green Power LED is continuously lit  
while the Hub is power ON. The red Fail LED will begin blinking if the Hub detects a malfunction in one of its  
fan modules or power supplies. The Fail LED will continue to blink until you look at the problem report in the  
System Status screen in the Hub’s LCD panel (see Section 7.5.5). Once you do so, the Fail LED will remain  
continuously lit until (a) the problem is resolved (the LED will go dark) or (b) another problem is detected  
(the LED will start blinking again).

7.5 The Functions of the Hub’s LCD Panel and Pushbuttons  
There is also a 4-line-by-20-character LCD panel on the Hub’s front panel. You can use this display and its four  
associated pushbuttons (Up, Down, Escape, and Enter) to configure your Hub, view its status, etc.  
7.5.1 THE IDLE DISPLAY SCREEN  
As soon as you power on your Hub, the Idle Display screen appears:  
---- KV170RA ----  
Chassis nnn  
Serial nnnnnnnnnn  
www.blackbox.com  
This is the Hub’s “starting” screen. “Chassis nnn” is the Hub’s chassis number; as shipped from the factory, it  
will be “000” and must be changed (see Section 7.5.3). “Serial nnn” is the Hub unit’s unique serial number,  
which can’t be changed.  
All of the Hub’s other screens (described in the following subsections) can be accessed from here by pressing

future firmware advances, this is the screen you’ll use to configure it:  
***Serial Port***  
Baud Rate:57600  
Data Bits:8  
Parity:No Stop:1  
This screen displays the settings that the serial port will require an attached PC to be configured for. Only the  
baud rate (data rate) is user-configurable. To change the baud rate, press the Hub’s Enter button. The Edit  
Mode screen appears:  
***Edit Mode***  
Baud Rate:57600  
Data Bits:8  
Parity:No Stop:1  
Press the Up and Down buttons to toggle between the two available rates: 57,600 bps and 38,400 bps. When the  
rate you want is displayed, press the Hub’s Enter button to switch to that rate and return to the Serial Port  
screen, or press the Hub’s Escape button to return to the Serial Port screen without switching to the new rate.  
7.5.7 THE LINK STATUS, SELECT SLOT, AND SELECT PORT SCREENS  
Press the Hub’s Down button five times from the Idle Display screen, or once from the Serial Port screen, to  
reach the Link Status screen, which displays connection information for one Hub port at a time. (The first time  
you access this screen after the Hub is powered ON, the information for Port 1 of Slot A will be the first thing  
shown. Afterward, until the Hub is powered OFF again, Link Status will begin by displaying the information for  
whatever port was last displayed the previous time you accessed this screen.)  
***Link Status***  
Slot: A Port: 05  
Link: 65-B-12  
In this sample screen, Port 5 of the Module in the Hub’s Slot A is connected to Port 12 of a Module in Slot B of  
another Hub unit with a chassis address of 65.  
To view the connections of another Module and port, press the Enter button. The Select Slot screen appears:

**** EDIT MODE****  
The currently selected language is shown. Press the Up and Down buttons to toggle between the two available  
languages: English and German. When the language you want is displayed, press the Hub’s Enter button to  
switch to that language and return to the Language screen, or press the Hub’s Escape button to return to the  
Language screen without switching to the new language.  
7.6 Flash Upgrading  
Like the Cards and Modules in all ServSwitch Multi models, the Hub’s Modules are Flash upgradable. Flash  
technology allows you to upgrade the Modules’ firmware without removing Modules or powering down the  
system. New firmware revisions can be uploaded into the Modules through standard serial connections to  
attached ServSwitch Multi models. For more information on Flash upgrading the Hub (and the rest of your  
ServSwitch Multi system), see Section 8.13.

SERVSWITCH™ MULTI  
7.7 Sample System Configurations  
This section shows a few examples of money-saving cascaded ServSwitch Multi systems designed around  
ServSwitch Multi Hubs. You can call Black Box Tech Support for help in determining whether your ServSwitch  
Multi system would benefit from using Hubs and, if so, how best to design your Hub-centered system.  
7.7.1 A 16 X 128 MATRIX  
In this configuration, 16 users can simultaneously access 128 attached computers. Any user can connect to any  
computer in the system without limitation or interference from another system user. Should two people need  
access to the same computer at the same time, they can share access: Both users can view the computer’s video,  
while one user at a time will have keyboard/mouse control (see Section 8.3).  
This configuration uses one Hub, sixteen ServSwitch Multi SB chassis to connect computers to the system,  
and four ServSwitch Multi EXP chassis to connect the users.  
Sixteen SBs, each with at least four Transmit Cards and eight CPU Cards installed, and 128 CPUs  
256 CAT5 cables  
Hub with at least 4 Receive Modules and  
1 Transmit Module installed  
32 CAT5 cables  
Four EXPs, each with at least two Receive Cards and four User Cards installed, and sixteen user stations

CHAPTER 7: The ServSwitch Multi Hub  
7.7.2 A 16 X 384 MATRIX  
In this configuration, 16 users can simultaneously access 384 attached computers. Here 256 computers have  
been added to the 16 x 128 matrix in Section 7.7.1, but any user can still freely connect to any computer.  
This configuration uses three Hubs, 48 ServSwitch Multi SB chassis to connect computers to the system, and  
four ServSwitch Multi EXP chassis to connect the users. With careful cabling, you could interconnect a 16 x 384  
matrix using only two Hubs (each with six Receive Modules and two Transmit Modules installed), but this  
would not leave much room for future growth.  
48 SBs, each with at least four Transmit Cards and eight CPU Cards installed, and 384 CPUs

SERVSWITCH™ MULTI  
7.7.3 A 32 X 256 MATRIX  
In this configuration, 32 users can simultaneously access 256 attached computers. Here the 16 x 128 matrix in  
Section 7.7.1 is effectively doubled, but any user can still freely connect to any computer. (There aren’t enough  
dedicated signal paths from any one EXP to any one Hub, or from any one Hub to any one SB, to make this  
work. But because each Hub has at least two paths to each EXP and at least two paths to each SB, there is always  
at least one available pathway between each user and each computer.)  
This configuration uses four Hubs, 32 ServSwitch Multi SB chassis to connect computers to the system, and  
eight ServSwitch Multi EXP chassis to connect the users.

CHAPTER 8: Operation  
8. Operation  
8.1 Basic Operation  
You can power up the computers you’ve attached to your ServSwitch Multi system one at a time or all at once.  
Operator intervention is not necessary during booting.  
The first thing you should do after booting your system is to check the front-panel LEDs of all of your non-  
Hub ServSwitch Multi s, because the LEDs provide your first indication of whether all system components are  
installed correctly or not, as shown in Table 8-1 on the next page.  
You can select a computer at the local console of a ServSwitch Multi Base Unit or MX by pressing the  
pushbutton corresponding to that computer’s channel on the Switch’s front panel. On the Base Unit, the  
channel letter will then be shown on the front-panel alphanumeric display. To select a computer channel from  
any console (user station) attached to a User Card, you have to either use the Card’s on-screen display (see  
Chapter 9) or type in a keystroke sequence from that console’s keyboard, as described in Section 8.2. The  
indicator lights (LEDs) on the front panel of a non-Hub ServSwitch Multi unit will change depending on which  
of the unit’s channels are selected. Again, refer to Table 8-1 on the next page.  
Unless you use the on-screen display, in order to (a) switch channels from a console attached to a User Card  
or (b) use the ServSwitch Multi’s channel-scanning feature (see Section 8.6), you must first place your system in  
Command Mode by pressing and holding your keyboard’s [Num Lock] key, pressing and releasing the keypad  
[–] (minus) key, and releasing [Num Lock]. As long as you are operating in Command Mode:  
• whatever you type will be intercepted by ServSwitch Multi (none of your keystrokes will be forwarded to the  
attached computer), and  
• the Num Lock, Caps Lock, and Scroll Lock LEDs on your keyboard will blink.  
You can exit Command Mode by pressing the [Enter] or [Escape] key on your keyboard. For more information  
about Command Mode, see Section 8.2.  
The ServSwitch Multi Base Unit has an alphanumeric display on its front panel. This display reflects the active  
channel for the local user console. For units with an address between 1 and 9, the display will show the unit  
address and the channel. For units with addresses higher than 9, the display will show an asterisk (“*”) in place  
of a unit address. For example, if channel G in Switch 7 is the current active channel at the local console, the  
display would show “7G”. If channel K in Switch 12 is active, it would show “*K”.

CHAPTER 8: Operation  
8.2 Keyboard Control  
8.2.1 KEYSTROKE NOTATION  
Throughout the rest of this chapter, we use some “shorthand” to abbreviate certain keystroke sequences and  
variables you can use to control the ServSwitch Multi through console keyboards:  
<CM>  
Enter Command Mode:  
1. Press and hold down the keyboard’s [Num Lock] key.  
2. Press and release the [–] (minus) key on the numeric keypad.  
3. Release the [Num Lock] key.  
Note: To choose an alternate hotkey sequence for entering Command Mode, see Section 8.12.  
[Enter]  
Press the keyboard’s Enter or Return key. Doing so will cause the ServSwitch Multi to execute the  
command you just typed in and then exit from Command Mode.  
Addr  
The “address” of the computer you’re selecting.  
In single-unit ServSwitch Multi systems, this address will correspond to the single letter designation  
(“A” through “D” on an MX, “A” through “L” on a Base Unit, “A” through “N” on an EXP or SB) of  
the channel port on the Switch that the computer is attached to.  
In cascaded systems, this address will correspond to the numeric unit address (1 through 254) of the  
ServSwitch Multi that the computer is attached to, followed by the single-letter designation of the  
computer’s channel port. For example, to select unit the computer on channel C of unit 9, enter  
“9C”.  
[Esc]  
Press the keyboard’s Escape key. Doing so will cause the ServSwitch Multi to abort: It will exit from  
Command Mode without executing any instruction.  
8.2.2 KEYBOARD-BASED SWITCHING  
Any user in a ServSwitch Multi system can issue a short sequence of keystrokes from their console keyboard to  
switch between computer channels. This is called “keyboard switching” or “hotkey switching.” To keyboard-  
switch channels, take these steps:  
1. The first set of keystrokes (see the description of <CM> in Section 8.2.1) places your system in Command  
Mode. As long as you are operating in Command Mode, whatever you type will be interpreted as channel-  
switching commands until you press the Enter or Escape key to terminate Command Mode. None of the  
keystrokes entered will be forwarded to the attached computer until you exit Command Mode.  
2. Next, enter the address (“Addr”—see the description in Section 8.2.1) for the channel you wish to select.  
3. Press [Enter] to accept the new channel.  
All together, the proper format for keyboard switching to a new active channel through the keyboard is  
“<CM>Addr[Enter]”. Below is a sample of a keyboard switching session for a single-unit system, with an  
accompanying explanation for each step:  
1. Type in “<CM>D[Enter]” to select channel D.  
2. Type in “<CM>A[Enter]” to select channel A.  
3. Typing in “<CM>G[Esc]” gets you out of Command Mode without any channel switch or other instruction  
being executed. Channel A remains selected as the active channel.

SERVSWITCH™ MULTI  
And here’s a sample of a keyboard switching session for a cascaded system, with an accompanying explanation  
for each step:  
1. Type in “<CM>8C[Enter]” to select channel C on unit 8.  
2. Type in “<CM>H[Enter]” to select channel H on the local unit (the unit that the console is attached to).  
3. Type in “<CM>76K[Enter]” to select channel K on unit 76.  
4. Typing in “<CM>112E[Esc]” gets you out of Command Mode without any channel switch or other  
instruction being executed. Channel K on unit 76 remains selected as the active channel.  
8.3 Multiuser Operation  
If your ServSwitch Multi system only has a single console, you can skip this section and go on to Section 8.4. But  
if users will be on the system simultaneously at multiple consoles, you need to be aware of how the ServSwitch  
Multi handles multiuser access. When users are accessing different computers or expansion channels, they can  
do so independently. When users try to access the same computer or expansion channel, they must share.  
At any given time, users attached to the ServSwitch Multi system may independently select and operate as  
many as (but not more than) eight different computers attached to the same ServSwitch Multi SB, or four  
different computers attached to the same Base Unit or EXP, or two different computers attached to the same  
MX. This is because there are only eight independent data pathways through each SB, only four independent  
pathways through each Base Unit or EXP, and only two independent pathways through each MX; once all these  
are carrying keyboard and mouse input from users to computers, no more independent connections can be  
established.  
Imagine a single Base Unit with computers attached to channels A through F. Through a single console  
attached to this Base Unit, a user could have full access to any of these computers any time he or she wanted.  
But say there are four users working with this Base Unit, one on the local console (user 1), the others on  
channels K, L, and M (users 2, 3, and 4). These users all want independent access to one of the six computers,  
so they each must select a different one: let’s say user 1 chooses computer A, 2 chooses B, 3 chooses C, and  
4 chooses E. In this situation, the only computers that any of these users can select and still remain  
independent are computers D and F.  
Now let’s say that user 2 wants to use computer A. User 2 can switch to computer A, but until user 1 finishes  
working with it, user 2 will only be able to see its video output, not send keyboard or mouse input. This is called  
“shared access.” User 2 can’t have independent access to computer A until user 1 stops sending keyboard and  
mouse data for the duration of computer A’s inactivity timeout (either one second or ten seconds; see  
Section 4.2.2). Once this timeout expires, user 2 can begin typing or pointing and clicking at any time and the  
ServSwitch Multi will immediately start passing that data through to computer A. At that point user 1 becomes  
the “sharing” user, seeing computer A’s video but having no keyboard or mouse control until user 2 is finished.  
Any user can share access to any computer with any other user in the system. There is no system limitation on  
the number of users that can share access at the same time. All of the users in your ServSwitch Multi system can  
share access to a set of your computers simultaneously—but only two, four, or eight users will be able to be  
actively working at any given moment.  
82

CHAPTER 8: Operation  
Of course, any time that more than the maximum independent number of users are trying to access  
computers attached to a single ServSwitch Multi unit, two, four, or eight of them will have independent access  
and the rest must share. Any attempt by a sharing user to connect to a third/fifth/ninth computer attached to  
the same Switch will be ignored. Figure 8-1 below shows a “mandatory sharing” system with five consoles. The  
users on consoles 3, 4, and 5 are using computers B through D respectively. They are working simultaneously  
and independently of each other. Consoles 1 and 2 are sharing computer A. Both consoles display video from  
computer A, but only one of the consoles can have actual control of the computer at any given moment.

INDEPENDENT ACCESS  
Figure 8-1. Independent vs. shared access in a multiuser system.  
In cascaded systems, the situation becomes more complicated. Each individual ServSwitch Multi still has two,  
four, or eight data pathways, but when a user selects a computer on another Switch, one pathway in each Switch  
between the user’s console and the computer will be occupied. For example, refer to Figure 6-4 in Section 6.1:  
For a user on Switch 0 to establish an independent connection to a computer on Switch 5, it would require the  
use of one data pathway in Switch 5 (from the CPU-Interface Card to the Transmit-Card port), one pathway in  
Switch 4 (from Receive-Card port to Transmit-Card port), one in Switch 1 (Receive-Card port to Transmit-Card  
port), and one in Switch 0 (Receive-Card port to local console or User-Interface Card).  
When you need to figure out the dynamics of data-path usage in any local ServSwitch Multi in a cascaded  
ServSwitch Multi system, just remember that each of these connections takes up one data path through the unit:  
• Local console to local computer.  
• Local console to remote computer through a port on a local Receive Card.  
• Remote console to local computer through a port on a local Transmit Card.  
• Remote console to remote computer through ports on local Transmit and Receive Cards.  
In cascaded systems, shared access applies not only to computers but also to expansion connections. If one  
ServSwitch Multi is attached to another by only a single link (from a Transmit-Card port on one Switch to a  
Receive-Card port on the other), and an active user at a console on the Switch with the Receive Card selects a  
computer on the Switch with the Transmit Card, other users on the Receive-Card switch can share access to that  
computer, but they cannot establish an independent connection to any computer on the Transmit-Card Switch  
until the active user selects a computer on a different Switch and relinquishes his or her “lock” on the  
expansion connection.

SERVSWITCH™ MULTI  
8.4 Multiplatform Keyboard Mapping (Character Translation)  
With the ServSwitch Multi, you can use any type of keyboard to operate any type of attached computer.  
However, when you “cross platforms” (operate a computer of one platform with a keyboard of a different  
platform), the Switch has to “remap” certain keys (that is, substitute another character for the one they  
normally generate) in order to provide all of the functions available on the keyboard native to the computer’s  
platform. For example, if you access a Sun workstation with a Macintosh keyboard, you will notice that the  
Macintosh does not have (among others) the [Stop] and [Again] keys that are on a true Sun keyboard. But  
when you turn Scroll Lock on, the ServSwitch Multi remaps the [F1] and [F2] keys on the Macintosh keyboard  
so that they function as the Sun [Stop] and [Again] keys. With Scroll Lock off, [F1] and [F2] function  
normally.  
Tables 8-2 through 8-5 on the following pages are the “translation tables” for PC, Macintosh and Sun  
keyboards respectively. Where a key is listed in one of these tables as “undefined,” the ServSwitch Multi absorbs  
the character generated by that key without transmitting any characters to the the computer. Where a key is  
listed in one of these tables as “untranslated,” the Switch passes the character generated by that key directly  
through to the computer without altering or substituting for it, regardless of the state of the Scroll Lock.  
All of the key mappings listed in these tables are valid only when Scroll Lock is on, except for the special  
[Alt]/[Start] “swap” (shown in Table 8-3) activated by the “Remap WIN95 Keys” System Configuration option  
(see Section 9.4.3.E). This mapping is active for that console’s keyboard regardless of the state of Scroll Lock,  
for as long as that remapping option is turned on, and takes effect whenever the user at that console selects a  
computer channel with a Macintosh attached.  
NOTE  
If you use Macintosh console equipment in a multiplatform system, you must use a  
serial mouse rather than an Apple mouse. This is because, while the remapping  
functions discussed in this section make it possible for a Mac keyboard attached to  
the Switch to emulate the functions of a PC or Sun keyboard, at the time of this writing  
there is no way for a one-button Apple mouse attached to the Switch to emulate a  
mouse with more buttons.

NOTE  
While these remapping functions make it possible for a Mac keyboard attached to the  
Switch to emulate the functions of a PC or Sun keyboard, at the time of this writing  
there is no way for a one-button Apple mouse attached to the Switch to emulate a  
mouse with more buttons. So if you use Macintosh console equipment in a  
multiplatform system, you’ll need to use a serial mouse instead of an Apple mouse.

CHAPTER 8: Operation  
8.5 Audio and Serial Functions (Audio Cables Only)  
The ServSwitch Multi supports attaching speakers/headphones and a microphone to every console in the  
system. If you have installed User Cables and Server Cables with audio capabilities, then you will have access to  
these features. The speakers and/or microphone that you have connected to your console will work exactly as if  
they were connected directly to your computer. When your console has independent keyboard/mouse control  
for a computer channel, then you will also have audio.  
For example, suppose that two consoles are sharing a computer: Console 1 has control and console 2 is just  
“along for the ride.” The speakers and microphone at console 1 are active, but the headphones at console 2  
aren’t; the user at console 2 can see the computer’s video signal, but that’s about it. When all keyboard and  
mouse activity at console 1 stops for the duration of the inactivity timeout (see Section 4.2.2), the user at  
console 2 may take control of the computer by simply moving the mouse or typing on the keyboard. Once  
user 2 takes control, his or her headphones become active, and the speakers and microphone at console 1 go  
dead.  
When you are using audio-type User and Server Cables, the ServSwitch Multi also supports input/output  
between computers’ RS-232 serial ports and any RS-232 serial peripheral that uses hardware (RTS/CTS) flow  
control at data rates up to 9600 bps or software (inband, X-ON/X-OFF) flow control at data rates up to  
115.2 kbps. Examples of such peripherals include most modems, serial printers, and serial touchscreens.  
As with the audio devices, users will be able to conduct serial I/O with a computer only when they have  
independent control over that computer. This means that while users in multiuser ServSwitch Multi systems are  
transmitting files across the serial link, they might want to continue to move their mouse or tap non-disruptive  
keys on their keyboard to prevent other users from taking control of that computer and accidentally breaking  
the serial connection. For transmission of large files or any other extended serial-only activity, users should  
establish Privacy-Mode connections (see Section 8.10).  
NOTE  
The ServSwitch Multi Hub does not carry the audio or serial signals. ServSwitch Multi  
users connected to a computer through a Hub will have keyboard, mouse, and video  
access only; they will not be able to establish audio or serial links with that computer.

SERVSWITCH™ MULTI  
8.6 Channel Scanning  
Once you activate the ServSwitch Multi’s channel-scanning feature, the Switch will automatically sequentially  
scan its channels without further intervention from you. When the Switch detects keyboard or mouse activity,  
scanning is suspended—the computer currently being scanned is temporarily selected—until all activity stops.  
Scanning then resumes with the next channel in sequence. You can change the “dwell time”—the length of  
time the Switch pauses at each computer channel (keeping that channel’s video on screen) during a scan—  
whenever you want to. Scanning is halted if you permanently select a computer channel or if you issue the Scan  
Halt command.  
You can control channel scanning with these keystroke-sequence commands:  
• Issue the Keyboard-scan Dwell command (“<CM>KDnn[Enter]”) to set the dwell time, where nn=a one- or  
two-digit number of seconds from 1 to 65. The default setting is “5” (5 seconds).  
• Issue the Keyboard-scan Go command (“<CM>KG[Enter]”) to start a scan of the computer channels  
beginning with the currently selected channel.  
• Issue the Keyboard-scan Halt command (“<CM>KH[Enter]”) to stop a scan in progress.  
• Cascaded systems only: Issue the Keyboard-scan Maximum command (“<CM>KMnnn[Enter]”) to indicate the  
highest ServSwitch Multi unit address that should be scanned, where nnn = a one-, two-, or three-digit  
decimal number from 1 to 254.  
• Cascaded systems only: Issue the Keyboard-scan Local Reset command (“<CM>KM0[Enter]”) to force the  
Switch to scan only its own local channels.  
Here’s a sample of a channel-scanning session, with an accompanying explanation for each step:  
1. Type in “<CM>KD10[Enter]” to set the dwell time to 10 seconds. During a scan, the ServSwitch Multi will  
pause for 10 seconds at each scanned channel.  
2. Type in “<CM>KG[Enter]” to start a scan. The Switch will display the currently selected channel for  
10 seconds, then the next channel in sequence for 10 seconds, and so on.  
3. Type in “<CM>KD3[Enter]” to set the dwell time to 3 seconds. The Switch will continue scanning, but will  
begin pausing at each channel for only 3 seconds.  
4. Type in “<CM>KH[Enter]” to end the scan. The channel that was being scanned when the command was  
entered becomes the selected channel.  
5. Type in “<CM>KG[Enter]” to start a new scan.  
6. Type in “<CM>J[Enter]” to end the scan by selecting channel J on the local ServSwitch Multi.

CHAPTER 8: Operation  
8.7 Broadcast Mode  
Using “Broadcast Mode,” each user on a ServSwitch Multi system can send commands to multiple computers in  
the system at the same time. By creating your own customized “broadcast group,” you can designate which  
computers you want to broadcast to. Once you enter Broadcast Mode, whatever you type is sent to all of the  
computers in your group regardless of which channel is active. If you just want to quickly include a range of  
channels in a broadcast group, it will not hurt anything to include other types of installed modules or Cards in  
the group, but broadcasting only affects CPU-Interface Cards. Each CPU-Interface Card can belong to only one  
console’s broadcast group at a time.  
You can control Broadcast Mode with these keystroke-sequence commands:  
• Issue the Broadcast Add command (“<CM>T+<channel list>[Enter]”) to add the channel(s) in <channel list>  
to a broadcast group. <channel list> can be either a single channel address or a range of channel addresses,  
entered in low-address-dash-high-address format (for example, “A-D” to indicate ports A through D of the  
local unit or “4C-5F” to indicate channels C and higher of unit 4 and channels A through F of unit 5). If you  
are in Broadcast Mode when you issue the command, the change in the broadcast group will not take effect  
until you exit and re-enter Broadcast Mode.  
• Issue the Broadcast Remove command (“<CM>T–<channel list>[Enter]”) to remove the channel(s) in  
<channel list> (see above) from a broadcast group. If you are in Broadcast Mode when you issue the  
command, the change in the broadcast group will not take effect until you exit and re-enter Broadcast  
Mode. Any time you’re not sure which channels are currently in your console’s broadcast group, you should  
issue a global Broadcast Remove command whose channel list includes every address in your system and  
rebuild your broadcast group from scratch.  
• Issue the Broadcast Go command (“<CM>TG[Enter]”) to enter Broadcast Mode; until you exit it, the  
ServSwitch Multi will send everything you type to all of the computer channels in the broadcast group, even  
if none of them are currently selected.  
• Issue the Broadcast Halt command (“<CM>TH[Enter]”) to exit Broadcast Mode.  
Here’s a typical broadcast session, with an accompanying explanation for each step:  
1. Type in “<CM>T-A-L[Enter]” to remove channels A through L on the local unit from any broadcast group  
you had previously established.  
2. Type in “<CM>T+A-B[Enter]” to add channels A and B on the local unit to your new broadcast group.  
3. Type in “<CM>TG[Enter]” to enter Broadcast Mode.  
4. Type in the first message or data that you want both channels A and B on the local unit to receive.  
5. Type in “<CM>T-A[Enter]” to remove channel A on the local unit from the broadcast group; it will continue  
to receive broadcast data for now, but will not be part of the group the next time you enter Broadcast Mode.  
6. Type in “<CM>T+3F[Enter]” to add channel F on unit 3 to the broadcast group; it won’t receive any  
broadcast data until the next time you enter Broadcast Mode.  
7. Type in any other message or data that you want both channels A and B on the local unit to receive.  
8. Type in “<CM>TH[Enter]” to exit Broadcast Mode and stop broadcasting data to local-unit channels A and B.  
9. Type in “<CM>TG[Enter]” to re-enter Broadcast Mode and start broadcasting to channel B on the local  
unit and channel F on unit 3.

SERVSWITCH™ MULTI  
8.8 Follow Mode  
In Follow Mode, a sharing user (see Section 8.3) can “follow” an independent user’s channel switching. For  
example, suppose John and Melissa are users at different consoles in a ServSwitch Multi system. Melissa is  
training John in server maintenance, so John is watching what she does at each computer. John wants to  
automatically change channels along with Melissa, so he places his console in Follow Mode, setting Melissa’s  
console as the leader. Now, when Melissa changes to a channel, John automatically switches to the same one.  
You can control Follow Mode with these keystroke-sequence commands:  
• Issue the Follow Leader command (“<CM>FOLLOWAddr[Enter]”) to identify a user channel as the leader  
your console should follow when you are in Follow Mode.  
• Enter the Save command (“<CM>SAVE[Enter]”) to save the Follow Leader setting in nonvolatile memory.  
• Issue the Follow Go command (“<CM>FOLLOW+[Enter]”) to activate Follow Mode.  
• Issue the Follow Halt command (“<CM>FOLLOW–[Enter]”) to quit Follow Mode.  
8.9 Swap Mode  
In Swap Mode, two users can automatically exchange a pair of computer channels whenever one switches to the  
other’s channel. For example, suppose John and Melissa are users at different consoles in a ServSwitch Multi  
system. When Melissa starts working on John’s computer, John wants to be automatically switched to Melissa’s  
computer, and vice versa. John and Melissa both place their consoles in Swap Mode. Now, John and Melissa will  
swap channels when either one switches to the other’s computer.  
You can control Swap Mode with these keystroke-sequence commands:  
• Issue the Swap Partner command (“<CM>SWAPAddr[Enter]”) to identify a user channel as the partner you  
want to swap computer channels with when you are in Swap Mode.  
• Enter the Save command (“<CM>SAVE[Enter]”) to save the Swap Partner setting in nonvolatile memory.  
• Issue the Swap Go command (“<CM>SWAP+[Enter]”) to activate Swap Mode.  
• Issue the Swap Halt command (“<CM>SWAP–[Enter]”) to quit Swap Mode.  
8.10 Privacy Mode  
When you select your computer channel in Privacy Mode by entering the “<CM>XAddr[Enter]” keystroke-  
sequence command, no other console in the system can switch to your channel. If any other users try to select  
your private channel, they will simply remain on their present channels instead. Take your channel out of  
Privacy Mode by switching to another channel or reselecting your current channel normally (“<CM>Addr[Enter]”).

CHAPTER 8: Operation  
8.11 Command Forwarding  
In the ServSwitch Multi system, one user can do “command forwarding” to send commands that affect another  
user’s connection. For example, suppose Melissa and John are users at different consoles, and that Melissa is  
training John and needs him to be in Follow Mode (see Section 8.8). No matter where she is relative to John’s  
location, she can use command forwarding to put John in Follow Mode without any intervention on his part.  
You can control Command Forwarding with these keystroke-sequence commands:  
• Issue the forwarding sequence “<CM>FWDAddr=Command[Enter]” to send Command to the User-Interface  
Card at Addr.  
• Issue the Forwarding Enable command (“<CM>FWD+[Enter]”) to enable command forwarding.  
• Issue the Forwarding Disable command (“<CM>FWD–[Enter]”) to disable command forwarding.  
8.12 Choosing an Alternate Command-Mode Hotkey  
If the standard <CM> Command-Mode hotkey sequence (press and hold Num Lock, press and release  
keypad [–], release Num Lock) conflicts with any of your applications, you can choose a different sequence by  
entering the “<CM>@n[Enter]” keystroke-sequence command, where n = the number designation, from 1 to 5,  
of the alternate command-mode hotkey sequence:  
Press-and-  
hold key:  
Press-and-  
release key:  
• Use <CM>@0[Enter] to select default:  
• Use <CM>@1[Enter] to select alternate 1:  
• Use <CM>@2[Enter] to select alternate 2:  
• Use <CM>@3[Enter] to select alternate 3:  
• Use <CM>@4[Enter] to select alternate 4:

SERVSWITCH™ MULTI  
8.13 Upgrading Card/Module Firmware Through Consoles’ Serial Ports  
When updated firmware is released for a ServSwitch Multi Interface Card, Expansion Card, Hub Module,  
Management Card, Serial Control Card, or Local-Console Module, you can download the new firmware to all of  
the affected components in your system through the serial-port connection of a local or secondary console. If a  
Black Box Technical Support technician asks you to do so, you can access the ServSwitch Multi’s firmware-  
configuration display by following one of the procedures described below. If, based on the information  
displayed, the technician determines that you need new firmware for a given component, he or she will tell you  
how to receive the new firmware from us. Once you’ve done that, you can send that firmware to the Switch  
components—again, by following one of the listed procedures.  
NOTE  
Cascaded systems only: In their factory-default state, all non-Hub ServSwitch Multis  
without Transmit Cards installed in them will have unit address 0. In order for you to  
be able to tell these Switches apart in the firmware-configuration display, and to  
download firmware to a Card or Module in the correct Switch, you will need to use the  
“<CM>CHASSIS=n[Enter]” command, where n is a number from 0 to 254, to assign  
every non-Hub Switch in your cascade a unique unit address. See the entry for that  
command in Section 8.15.  
Access the ServSwitch Multi’s firmware menus/displays in any of these ways:  
• If any of the computers attached to your ServSwitch Multi system through a CPU-Interface Card has an  
RS-232 serial port and terminal-emulation software:  
1. Store the new firmware files on that computer.  
2. Attach the serial-port strand of that computer channel’s audio-type Server Cable to that computer’s serial  
port. (If you’ve been using a standard Server Cable with that channel, either you’ll need to replace it with  
an audio-type cable or you’ll need to use a different computer.)  
3. Select that computer’s channel, in Privacy Mode (see Section 8.10), from your ServSwitch Multi console.  
4. Run the terminal-emulation software.  
5. Set the software to use the correct COM port and set its serial communication parameters: 1200 to  
19,200 (but not 14,400) bps, no parity, 8 data bits, 1 stop bit, and no flow control.  
6. Use <CM>ZB[Enter] to access the firmware-configuration menu (see Figure 8-2 at the end of this section).  
• If none of the computers attached to your ServSwitch Multi system through a User-Interface Card has both  
an RS-232 serial port and terminal-emulation software, you’ll need to place a computer that does nearby.  
Once you do, the question becomes whether or not you have a null-modem cable (such as our product  
code EYN257H-0006-FF) handy. If you do:  
1. Store the new firmware files on the terminal-capable computer.  
2. Go to a monitor, keyboard, and mouse that are attached to either (a) a User-Interface Card with On-  
Screen Display (UICD, our part number KV2550C-R2) or (b) the Local-Console Module of a Base Unit  
or MX. (This procedure can’t be done from a console attached to a Universal User-Interface Card  
[UUIC, our product code KV2500C].) If you choose to use a UICD console, run the null-modem cable  
from the terminal-capable computer’s serial port to the serial-device (not serial-mouse) connector—the  
one without a yellow band—on your console’s User Cable. If you choose to use a local console, run the  
null-modem cable from the terminal-capable computer’s serial port to the local console’s “SERIAL  
PORT” connector on the front panel of the Base Unit or MX.

CHAPTER 8: Operation  
3. Run the terminal-emulation software on the terminal-capable computer.  
4. Set the software to use the correct COM port and set its serial communication parameters: 1200 to  
19,200 (but not 14,400) bps, no parity, 8 data bits, 1 stop bit, and no flow control.  
5. Use <CM>ZF[Enter] to access the firmware-configuration menu (see Figure 8-2 at the end of this section).  
• As above, if you don’t have a null-modem cable:  
1. Store the new firmware files on the terminal-capable computer.  
2. Attach the serial-mouse strand of your console’s User Cable to that computer’s serial port.  
3. Run the terminal-emulation software on the terminal-capable computer.  
4. Set the software to use the correct COM port and set its serial communication parameters: 1200 to  
19,200 (but not 14,400) bps, no parity, 8 data bits, 1 stop bit, and no flow control.  
5. Use <CM>ZS[Enter] to access the firmware-configuration menu (see Figure 8-2 at the end of this section).  
Once you’ve issued the appropriate command, the ServSwitch Multi will switch control to the terminal-capable  
computer, autodetect the data rate the terminal is set for, and match it. Press [Enter] at the terminal PC’s  
keyboard when the Switch prompts you to do so. The Switch should display the main firmware-configuration  
menu on your terminal screen:  
1) Display chassis configuration  
2) Download local to remote Flash ROM  
3) Download Serial Port to Flash ROM  
Q) Quit  
(you must choose this option to upgrade a Hub!)  
Your choice:  
Choosing option 1 (by pressing “1” on your terminal keyboard) causes the Switch to prompt you for a unit  
address; either enter one, or press [Enter] for the local Switch. The Switch displays the chosen unit’s firmware  
configuration (as shown in Figure 8-2 at the end of this section) on the terminal screen, then waits for you to  
press [Enter] and returns you to the firmware-configuration menu when you do so.  
Choosing option 2 (by pressing “2” on your terminal keyboard) causes the Switch to copy the firmware from  
one Card or Module to another of the same type. (Once you’ve downloaded revised firmware to one  
component—see the paragraph for option 3 below—option 2 is quite useful for quickly disseminating the new  
firmware to all of the components of the same type in your system.) The Switch will prompt you for the  
addresses of the source Card/Module and the destination Card/Module, and will then copy the firmware from  
source to destination. Once this process is successfully completed, you will be returned to the firmware-  
configuration menu, and the destination Card or Module will automatically reset itself and starting running  
using its upgraded firmware. If, however, an error occurs during transmission, just try again; the destination  
Card or Module will not attempt to execute the new firmware code, but will continue using the old firmware  
until a successful transfer is made.  
Choosing option 3 (by pressing “3” on your terminal keyboard)—which is necessary in order to upgrade a  
Hub Module—causes the Switch to copy revised component firmware from the computer you’re using for the  
terminal emulation to a Switch component that you want to upgrade. First the Switch will prompt you for the  
address of the destination Card/Module. Then it will prompt you to start a transfer of the firmware file using  
the XMODEM file-transfer protocol; when it does, have the terminal-emulation program perform an  
XMODEM upload of the file. Once this process is successfully completed, you will be returned to the firmware-  
configuration menu, and the destination Card or Module will automatically reset itself and start running using  
its upgraded firmware. If, however, an error occurs during transmission, just try again; the Card or Module will

SERVSWITCH™ MULTI  
not attempt to execute the new firmware code, but will continue using the old firmware until a successful  
transfer is made.  
Choosing option Q (by pressing “Q” on your terminal keyboard—it doesn’t matter whether it’s upper- or  
lowercase) exits the firmware-configuration menu and transfers control from the terminal PC back to the user  
console from which you originally issued the command to access the menu.  
At any point that the terminal is at a prompt (when the Switch is idle, waiting for input from the terminal),  
you can go back to the console from which you entered the command to access the firmware-configuration  
menu; from there, you can send the Switch the <CM>ZQ[Enter] command to force the Switch out of firmware-  
upgrade mode and back into normal operation. This command can come in very handy if you access the menu  
before realizing that your terminal-capable computer is not on, is not properly connected, isn’t running the  
terminal software yet, etc. Once a firmware transfer has started, this command has no effect; you’ll have to wait  
for the transfer to finish, then try again. If possible, you should exit from the firmware-configuration menu by  
pressing Q at the menu prompt (see the previous paragraph) rather than sending <CM>ZQ[Enter].

NOTES  
1. The “Chan.” column lists the channel address of each component (Card or Module). For Base Units, the  
option slot will always be listed as channel “M,” and the Local-Console Module will always be listed as  
channel “N.” For MXs, the Local-Console Module will always be listed as channel “E.” For Hubs, the Front-  
Panel Element will always be listed as channel “J”.  
2. The “Card Type” column shows what type of component it is: “LCI”=Local-Console Module, “XPAC”=CPU-  
Interface Card, “XPLU”=Universal User-Interface Card, “XPDU”=User-Interface Card with On-Screen Display,  
“XPXT”=regular Transmit Card, “XPXR”=regular Receive Card, “XPST”=CAT5 Transmit Card, “XPSR”=CAT5  
Receive Card, “XPIQ”=Management Card, and “XPSI”=Serial Control Card. (Current User-Card firmware can’t  
recognize the codes that the Hub’s Modules and Front-Panel Element return, so “????” is reported for these.)  
3. The “HW Rev.” column lists the revision level of the component’s hardware.  
4. The “EPROM FW Rev.” column lists the revision level of the component’s original firmware (that is, the  
firmware burned into its EPROMs at the factory).  
5. The “EPROM FW Rev.” column lists the revision level of the most recent firmware (if any) that has been  
downloaded to the component’s flash ROMs.  
6. The “Serial #” column lists the component’s serial number. Unless the component is an eval, demo, or special  
unit, the serial number should always be numeric.  
7. The “Other Information” column shows the Switch’s best guess of what the component is attached to (if  
anything) based on the states of the ground leads of the component’s connector(s).  
8. What “* - Indicates active device” means is that the asterisk shows whether the component is running using  
the firmware in its EPROMs or the firmware in its flash ROMs.

SERVSWITCH™ MULTI  
8.14 Overriding the Settings of a CPU-Interface Card’s DIP Switches  
In addition to their physical DIP switch (see Section 4.2), the CPU-Interface Cards support a “virtual DIP  
switch” that you can set with keyboard commands in order to override the physical DIP switch’s settings. (This  
can be very convenient if the CPU-Interface Card in question is far away or otherwise hard to get at.) Any  
changes to the virtual switch will remain in effect until you either change it again or you move the positions of  
the physical DIP switch. (Whenever changes are made to the physical DIP switch, the virtual switch resets itself  
to match the physical-switch settings.)  
To override all of the DIP-switch positions at once, take these steps:  
1. Referring to Section 4.2, determine how you want to set each DIP-switch position. Going left to right from  
position 8 to position 1, write down a “1” for each position you want to be ON and a “0” for each position  
you want to be OFF. When you finish, you should have an eight-digit binary code that corresponds to your  
desired switch-position settings. (Positions 8, 7, and 6 are reserved for future use and should always be  
OFF, so the first three digits of the code should be “0 0 0”.)  
2. Convert the binary code you derived in step 1 into a decimal number (you can refer to Table C-1 in  
Appendix C).  
3. Select the computer channel whose physical DIP-switch settings you want to override.  
4. Send the <CM>SW+[Enter] command to enable the override of the physical DIP switches on all of the  
system’s CPU-Interface Cards.  
5. Send the <CM>SW=x[Enter] command, where x is the decimal number you derived in step 2.  
To override one DIP-switch position at a time, take these steps:  
1. Referring to Section 5.2, determine how you want to set the DIP-switch position. Write down a “1” if you  
want it to be ON or a “0” if you want it to be OFF.  
2. Select the computer channel whose physical DIP-switch settings you want to override.  
3. Send the <CM>SW+[Enter] command to enable the override of the physical DIP switches on the system’s  
CPU-Interface Cards.  
4. Send the <CM>SWn=b[Enter] command, where n is the switch-position number and b is either 1 (if you  
want to turn the position ON) or 0 (if you want to turn the position OFF). For example, send  
“<CM>SW4=1[Enter]” if you want to force a 10-second keyboard/mouse-inactivity timeout on that  
channel.  
To disable the use of virtual switches to override the physical DIP switches, send the <CM>SW–[Enter]  
command.

CHAPTER 8: Operation  
8.15 Other Commands: System Control and Maintenance  
The ServSwitch Multi supports a number of other keystroke-sequence commands for system control and  
maintenance:  
Command  
Function  
<CM>CHASSIS=n[Enter]  
Cascaded systems only: Sets the unit address of the local ServSwitch Multi (the  
one your console is attached to) to n (a number from 0 to 254). If you have  
Transmit Cards installed in all of your Switches, you won’t need to issue this  
command; the Switches’ unit addresses will be set on the Cards’ DIP switches  
(see Section 6.3.1). If more than one of your Switches have only Receive Cards  
installed in them, however, you will have to issue this command to set them to  
unique addresses in order to view or update the firmware of Cards or local-  
console modules installed in them (see Section 8.13). (This is because the  
factory-default unit address of all ServSwitch Multis is zero, and it remains zero  
for any given Switch—unless you install a Transmit Card in it—until you issue  
this command.)  
If you send this command to a Switch with any Transmit Cards installed in it,  
and n does not match the address setting of those Cards, that Switch will  
behave as if you’ve installed a Transmit Card with a non-matching address in it:  
The LEDs of all Transmit Cards in that Switch will start blinking, and you’ll  
have to either issue another CHASSIS=n command or physically change the  
unit-address settings of the Cards to get that Switch working again.  
<CM>Kn[Enter]  
Sets the scan mode (n = 1, 2, or 3) of the keyboard signals the Switch should  
send to the currently selected IBM PC compatible computer. Scan mode 2 is  
used by the vast majority of CPUs, and is also the default state of all 101-key and  
PS/2 keyboards. Mode 1 is used primarily by certain older PS/2 CPUs. Mode 3  
®
is used by RS/6000 CPUs, some other PC type UNIX based computers, and  
certain specialized servers. Issue this command if your computer is behaving in  
a way that seems to indicate that it is misinterpreting what you’re typing.  
<CM>M+[Enter]  
Re-enables your mouse for use with the currently selected channel. Issue this  
command after you attach a different type of mouse to your console or after  
you send the “RESET” or “RESETAddr” command (see below) to the currently  
selected computer channel.  
<CM>OFF[Enter]  
Logs you off of the system: Your console deselects your previously selected  
computer channel—freeing up a data pathway through the switch if you were  
an independent user—and your monitor screen goes blank. The monitor is not  
reactivated again until a channel is selected from your console.  
<CM>RESET[Enter]  
Resets your console’s User-Interface Card. You might have to enter the “M+”  
command (see above) afterward to get your mouse working properly.  
<CM>RESETAddr[Enter]  
<CM>SAVE[Enter]  
Resets any User or CPU-Interface Card in the system.  
Saves your console’s Follow Leader and Swap Partner settings (if any; see  
Sections 8.8 and 8.9) to the ServSwitch Multi’s nonvolatile memory. Unless  
these settings are saved, they’ll be lost if the Switch loses power or is turned  
OFF.

Command  
Function  
<CM>SUN=n[Enter]  
Consoles with non-U.S.-English Sun keyboards only: Forces all CPU-Interface  
Cards attached to Sun computers to emulate key codes specific to the keyboard  
language corresponding to decimal number n. To determine the number of  
the correct keyboard language for your system, refer to your Sun  
documentation.  
<CM>SUNI=n[Enter]  
Consoles with non-U.S.-English Sun keyboards only: Forces the currently selected  
computer channel’s CPU-Interface Card to emulate key codes specific to the  
keyboard language corresponding to decimal number n. To determine the  
number of the correct keyboard language for your system, refer to your Sun

CHAPTER 9: Using the On-Screen Display (UICD Consoles Only)  
9. Using the On-Screen Display  
(UICD Consoles Only)  
9.1 Display Overview  
9.1.1 FEATURES  
The ServSwitch Multi User-Interface Card with On-Screen Display (“UICD” for short, our product code  
KV2550C-R2) adds on-screen menus and other advanced features to the ServSwitch Multi. For instructions on  
how install a UICD and its associated cables and equipment, see Chapter 3. For instructions on using the UICD  
with a non-multisync monitor, see Section 9.5.  
With the UICD’s on-screen displays, you can quickly and easily identify the servers attached to the ServSwitch  
Multi and select ones to interact with. Name your servers for easy recognition, then select them from a pop-up  
menu. You can keep the name of your currently selected server on screen at all times, or for just the first few  
seconds after you make a new selection. With other control features, you can manage your scanning and  
broadcast operations on-screen as well.  
You can define as many as 32 user profiles for each UICD. Use the Card’s advanced multi-level security-setup  
features to configure and control server access for each defined user in the system. The administrator has full  
access privileges; other users have viewing, viewing/editing, or full viewing/editing/power-control access to  
each attached server.  
For additional security, you can turn on the UICD’s inactivity-logout feature. When this is turned on for a  
given console, once a period of user inactivity (from 1 to 60 minutes—see Section 9.3.2.A) elapses, that user’s  
currently selected channel is deselected and his or her monitor screen goes blank. The user must log in again  
to regain system access.  
9.1.2 LOGGING IN AND OUT OF THE SYSTEM  
To log into the ServSwitch Multi’s on-screen display system from its User Login screen, enter your assigned user  
name and password (or, if you’re the system administrator, your administrator name and password—see  
Section 9.3.2.A).  
When you are finished working with the Switch, activate the on-screen display (if it isn’t already active) and  
press the [F10] key. The User Login screen will appear again. That’s all there is to it; you or any other user will  
have to log back in to continue working on the system.

SERVSWITCH™ MULTI  
9.2 The On-Screen Menus  
The UICD’s on-screen display consists of four main windows: the Channel-List Menu, the User-List Menu (for  
the administrator only), the User/Administrator-Controls Menu, and the Command-Line-Entry Window. To  
access the Channel-List Menu, press either [Ctrl] (control) key on the shared keyboard twice within one  
second; press [Alt] + [Tab] to cycle through the remaining menus. While you’re in the on-screen display  
system, you can press [F1] at any time for context-sensitive help.  
Certain menus and commands within the on-screen display are only available if you’re logged in as the system  
administrator. Any options that can only be used by system administrators will be covered in Sections 9.3 and  
9.4. The rest of Section 9.2 deals with menus and options that can be accessed by all system users.  
9.2.1 THE CHANNEL-LIST MENU  
Once you have logged into the ServSwitch Multi’s on-screen display system, the Channel-List Menu (shown in  
Figure 9-1) is the first menu displayed. After login, you may activate the Channel-List Menu by pressing either  
of the keyboard’s [Ctrl] keys twice within one second. This menu lists all named computer channels in your  
system with their ServSwitch Multi channel addresses and access status. The administrator will always have full  
access to every server; for full descriptions of all of the administrator’s options at the Channel-List Menu, see  
Section 9.3. Individual user profiles will have varying degrees of access, determined by the system administrator.  
Only the channels that are included in a user’s profile will be listed. (See Section 9.4 for more details.)

Figure 9-1. The Channel-List Menu.  
This menu shows the name of, ServSwitch Multi address of, and individual access privileges for, each server.  
(Access privileges are shown as “V,” “K,” and “P”—see Table 9-3 at the end of Section 9.3.2.E.) Use the  
keyboard’s up- and down-arrow keys and the page-up and page-down keys to select a channel. You can move  
immediately to the top or bottom of the list with the [Home] and [End] keys. Press [Enter] to switch to your  
selected channel. To exit the on-screen display without changing channels, press [Esc].  
The white bar at the bottom of the menu lists all of the available menu options; use the [F11] key on the  
shared keyboard to scroll through them (see Table 9-1 on the next page for the user options; see Table 9-2  
following Section 9.3.1.C for the administrator options).

CHAPTER 9: Using the On-Screen Display (UICD Consoles Only)  
To switch to a channel normally, simply highlight that channel and press [Enter].  
To switch to a channel in Privacy Mode (see Section 8.10), highlight that channel and press [Alt] and [Enter]  
at the same time.  
To sort the channel list by name, press the [+] key on the keypad of the shared keyboard while the Channel-List  
Menu is on screen. To sort the list by address, press the keypad’s [–] key. (The [+] and [–] keys on the top row  
of the keyboard will not be recognized.) The “<” and “>” symbols will bracket the Menu’s “Name” or “Address”  
heading to show which of the two characteristics the list is currently sorted on.  
You can also search the channel list. These searches will be based on sort order: If the list is currently sorted  
by Name, you can search the names, or if the list is currently sorted by Address, you can search the addresses.  
To perform a search, bring up the Channel-List Menu and sort the entries as desired. Next type the first letter  
or number of the name or address you want to search for, then the second, and so on. For example, if the list  
were sorted by name, typing “M” would move the cursor to the names that begin with the letter “M”;  
proceeding to type an “A” would move the cursor to the names that begin with “MA”; and you could continue  
adding characters until you reached your desired entry.

CHAPTER 9: Using the On-Screen Display (UICD Consoles Only)  
9.3 Administrator Functions in the Channel-List and User-List Menus (Administrator Only)  
Each User-Interface Card with On-Screen Display in your ServSwitch Multi system has to have an administrator  
and its own set of administrator and user configurations. However, you can crossload configurations between  
UICDs in your system if you want to.  
A UICD’s administrator can configure his own profile and those of the other UICD users with a set of special  
options in the Channel-List and User-List menus. These options are described in the following subsections; to  
perform any of them, you must be logged on as the administrator. (On a newly installed UICD, or on one  
without a defined administrator password, you will automatically logged on as the administrator.)  
9.3.1 CHANNEL-LIST MENU FUNCTIONS  
Before taking any of these actions, make sure you configure your own administrator setup (see Section 9.3.2.A).  
Once you have, access the Channel-List Menu by pressing the [Ctrl] key on the shared keyboard twice within  
one second. Note that the white bar at the bottom of the menu lists all of the available menu options; use the  
[F11] key on the shared keyboard to scroll through them (see Table 9-2 following Section 9.3.1.C).

3. Enter the desired scan-dwell time for this channel (that is, the length of time the ServSwitch Multi will  
pause to display the channel while scanning).  
4. Enter the ID-window-display information. The ID window displays the name of the current channel on  
your screen after you switch channels. You can enter the window’s text size, field length, text color, and  
background color from this menu, or visually adjust these values later as described on the next page.  
5. Enter a value, in seconds, for the ID-window dwell time (that is, the length of time the ServSwitch Multi  
will display the ID window). If you enter a value of 0 (zero), the ID window will never appear at all. If you  
enter the maximum value of 255, the Switch will display the ID window at all times.  
6. If you’re running two video outputs from this computer to dual monitors as described in Section 3.3.5,  
press the space bar to enable the “Dual Video” feature. (If you do this, you’ll also have to designate which  
User-Interface Card the secondary monitor is attached to—see Section 9.4.3.H.) Pressing the space bar  
again disables Dual Video.

9.4.1 BROADCASTING (ENABLE/DISABLE BROADCAST MODE)  
Highlight “Broadcasting” in the Administrator-Controls Menu and press the space bar to toggle Broadcast  
Mode on or off. For information about Broadcast Mode, see Section 8.7.  
9.4.2 CONFIRM DELETES (ENABLE/DISABLE DELETE CONFIRMATION)  
Use this option to specify whether users must confirm the deletion of a channel or user before the command is  
processed. Highlight “Confirm Deletes” in the Administrator-Controls Menu and press the space bar to toggle  
this option on or off.  
9.4.3 SYSTEM CONFIGURATION (CONFIGURE SYSTEM FUNCTIONS)  
Select this option in the Administrator-Controls Menu in order to configure a variety of system functions, as  
described in the following subsections.  
9.4.3.A Chassis Number  
If you don’t have an Expansion Transmit Card (KV1601C or KV1603C) in the ServSwitch Multi that the UICD is  
installed in, you can use this option to set a unique chassis address for the Switch. Chassis addresses are  
numeric, and may be any value between 1 and 254. Unit addresses of “0” and “255” are reserved.  
If you already have a chassis number assigned to this Switch, leave the value in this field at “0”. This doesn’t  
mean that the chassis address is “0”; it just means that the UICD won’t try to give the unit a chassis number  
itself.

CHAPTER 9: Using the On-Screen Display (UICD Consoles Only)  
9.4.3.B Command Key Sequence  
Highlight this option and use the space bar to cycle though the available hotkey sequences for bringing up the  
Command-Line-Entry Menu. Choose from:  
• [Num Lock] + keypad [–] (minus)  
• [Num Lock] + keypad [*] (asterisk)  
• [Num Lock] + keypad [+] (plus)  
• [Num Lock] + keypad [/] (slash)  
• [Ctrl] + [~] (tilde)  
9.4.3.C Menu Activation Key Sequence  
Highlight this option and use the space bar to cycle through the available hotkey sequences for activating the  
on-screen display system. You can choose [Ctrl], [Ctrl] (press and release [Ctrl] twice in succession); [Alt],  
[Alt]; or [Shift], [Shift].  
9.4.3.D Remote Commands  
Highlight this option and use the space bar to either enable or disable your UICD’s ability to accept remote  
commands from other UICDs. For more information on remote commands, see Sections 9.2.3.C and 9.2.3.D.  
9.4.3.E Remap Windows Keys  
This option determines whether the UICD will remap the Alt and Windows Start keys on a 104/105-key PC  
keyboard when a Macintosh computer is selected (see Section 8.4). Normally the PC’s Alt keys function as the  
Mac Option (Alt) keys, and the PC’s Windows Start keys function as the Mac (Command) key. But the  
arrangement of the PC Alt and Start keys is the reverse of the Mac Option and Command keys, so, if you’re  
used to the Mac layout, you can highlight this option and press the space bar to enable remapping of the PC  
keys so that PC Alt = Mac Command and PC Start = Mac Option. Press the space bar again to disable  
remapping.  
This remapping option is intended for newer 104/105-key keyboards that have the Windows keys. Older  
101/102-key keyboards that don’t include these keys should use the DIP-switch translation option instead. (See  
Section 4.2.3. Unlike the DIP-switch function, this option involves the console rather than the computer, is not  
affected by Scroll Lock, and operates only when a Mac is selected rather than continually.) Do not activate both  
types of remapping at the same time.  
9.4.3.F Standalone RSP  
This option is not supported at this time.  
9.4.3.G Follow/Swap Feature Status  
Highlight this option and use the space bar to start Follow Mode or Swap Mode or to quit either process. If you  
are starting Follow or Swap Mode, you’ll also have to enter the user address you are following or swapping with.  
For more information on Follow Mode or Swap Mode, see Section 8.8 or Section 8.9 respectively.  
9.4.3.H Card Address for Dual-Monitor Support  
If your ServSwitch Multi system is configured for dual-monitor support (see Sections 3.3.5 and 9.3.1.A), use this  
option to specify the address of the Universal User-Interface Card (UUIC) that the second monitor is attached  
to. If this field is left blank, dual monitor support will still be disabled even if the “Dual Video” option in the  
source computer’s CPU-Interface Card configuration (see Section 9.3.1.A) is enabled.

9.4.4 CONFIGURATION CONTROL (TRANSFER CONFIGURATION SETTINGS)  
Take these steps to send the configuration settings from the User-Interface Card with On-Screen Display that  
you’re working at to another UICD elsewhere in your ServSwitch Multi system, or to receive the configuration  
settings from another UICD (use the [Tab] or arrow keys to move through the fields):  
1. At the Administrator-Controls Menu, highlight “Configuration Control” and press [Enter].  
2. Use the spacebar to cycle through the available configuration-port options. Select “Internal.”  
3. Enter the port address of the remote UICD. Be sure to include the unit address and port letter (“3H,” for  
example).  
4. Use the spacebar to toggle to the desired setting in the “Direction of Transfer” field. If you are sending  
configuration settings from your UICD to the remote UICD, select “Send.” If you are receiving  
configuration settings from the remote UICD, select “Recv.”  
5. Enter the administration password for the remote UICD.  
6. Highlight the Begin Configuration field and press [Enter]. The remote UICD will display a message  
stating that a transfer is in progress. When the transfer is complete, the UICD that received the  
configuration will restart itself; this will blank the attached monitor’s screen for several seconds.  
9.5 Using the On-Screen Display with a Non-Multisync Monitor  
The normal default synchronization for the UICD’s on-screen display is PC-type separate horizontal and vertical  
(H/V) sync. When you select a Sun, Mac, or other computer that uses some other kind of sync, and that  
computer’s CPU-Interface Card is set to pass the video through unaltered, the UICD will output the on-screen  
display with sync that matches that of the selected computer’s video.  
All of this works fine when your monitor is a multisync type. But when your monitor uses a particular fixed  
type of synchronization, especially if it’s a type of sync other than H/V, the display (in its factory-default setting)  
will not appear on screen properly when there’s no computer video to lock onto (when, for example, the  
selected computer is off or is not outputting video for whatever other reason).  
For the UICD to work properly with such a non-multisync monitor, you need to change the UICD’s default  
synchronization. To do this, take these steps:  
1. Send the menu-activation hotkey sequence (which is [Ctrl] twice in succession, unless you’ve changed it—  
see Section 9.4.3.C) to trigger the on-screen display (even if you can’t see it). If you’ve disabled menu  
activation (see Section 9.2.3.B), send the Command-Mode hotkey sequence to bring up the Command-  
Line-Entry Window (see Section 9.2.4).  
2. Press the four keys [Ctrl] + [Alt] + [Shift] + [M] simultaneously.  
3. The UICD will begin cycling through various types of synchronizations. It will switch to a different sync  
type approximately every ten seconds. When it gets to one that your monitor can display, press [Enter] to  
have the UICD save that sync type in NVRAM as its default. If you want to quit the process without  
selecting a new synchronization, press [Esc]; the Card will continue using whatever type of sync it was  
using before.  
Also press [Esc] to terminate the process if, after two minutes, the UICD doesn’t find a matching sync  
option. If this proves to be the case with your monitor (which should virtually never happen), you will have  
to use a different monitor.  
If you swap in another non-multisync monitor later, just repeat this process to adjust the synchronization again.

CHAPTER 10: Using Management and Serial Control Cards  
10. Using Management and Serial  
Control Cards  
The ServSwitch Multi Management Card (KV1608C-R2) and Serial Control Card (KV1609C) add advanced  
serial-control features to the ServSwitch Multi. For an introduction to these Cards and for instructions on how  
to install them and their associated cables and equipment, see Chapter 5.  
10.1 Addressing Terminals on the Serial Control Card  
Since each Serial Control Card has four ports, channel addressing (for port-selection purposes) requires more  
than just a chassis number and slot letter. You must also designate which port on the Serial Control Card the  
terminal is attached to. Ports are numbered from top to bottom as shown in Figure 10-1.  
Port 1  
Port 2  
Port 3  
Port 4  
Figure 10-1. Port addresses on a Serial Control Card.  
For example, the terminal attached to the second port on the Serial Control Card in slot D of chassis 15 would  
be addressed “l5D2.”

troubleshooting. The System Management Tools can also be accessed through the Administrator Control  
Menu. Refer to Section 10.4.  
ALT-C  
Used to close the currently active session (deselect the current channel). Once you close a session, the Options  
Screen will appear until you select another channel as active. This is the only method available for closing a  
session. For more information on opening and closing a session, see Section 10.3.3.  
ALT-I  
This command displays the current channel address, the EPROM date, and the hardware, firmware, and Flash  
revision dates of your Management Card. Press any key to exit this information window.  
ALT-B  
This command is used to emulate the BREAK key found on many ASCII terminals. Its function depends on the  
device you’re working with and the application you’re using.  
ALT-Tab  
After you press [Alt] + [M] to initiate your menuing system, use [Alt] + [Tab] to cycle through the three  
available system menus. [Alt] + [Tab] is also used to cycle through your open sessions in the Open-Session  
Menu (see Section 10.3.3).

10.3.1.B Searching the Channel List  
Channel searching will be based on the currently active sort order. If you are currently sorting by name, a  
search will be performed on the Name field. If Address is the current sort field, a search will be performed on  
the system addresses.  
To search, bring up the Serial Channel-List Menu and enable the sort order of your choice. Next enter the  
first letter or number you wish to sort on. The next key you press will add the second letter or number to your  
search string, and so on.  
For example, if you are sorting by name, entering “M” will move your cursor to all entries that begin with the  
letter M. Enter “A” and your cursor moves to entries beginning with MA. Continue until you reach your desired  
entry.  
10.3.1.C Crossloading the Channel List  
Once you edit the channel list, you can send it to the other Management Cards in your system with option 9 in  
the System Management Tools Main Menu, “Transfer Channel List.” See Section 10.4.8 for more information.  
10.3.2 THE ADMINISTRATOR-CONTROLS MENU  
This menu contains two options for ServSwitch Multi maintenance and troubleshooting: “System Management  
Tools” and “System Security Monitor.”  
The System Management Tools window contains ten items, nine of which can be selected. You can display  
information on the type and revision level of each Card installed in the Switch, as well as the Flash-ROM status  
of any installed Card that has Flash ROM. You can also download firmware to your Management Cards or relay  
firmware from the Management Cards to other Cards. Select other available options to set the Cards’ date and  
time, transfer channel lists or the security log, or search your system for connected ServSwitch Multis. For more  
details, see Section 10.4.  
Selecting the System Security Monitor option brings up a three-part window on your monitor. From here, you  
can track the logging and switching history for every system user. Active system users are listed next to their  
currently selected channel. If any unauthorized activity occurs, an alert screen lists the date, time, user, and  
specific action. For more details, see Section 10.5.

10.3.3 THE OPEN-SESSION MENU  
10.3.3.A What Is “Opening a Session”?  
When you select a device attached to an Serial Control Card, it is called “opening a session.” The selected  
channel’s video appears on your monitor and the channel name is displayed in the lower right-hand corner. If  
you open a second channel, that channel becomes the currently active channel, and the first channel becomes  
inactive (but remains open). The new channel’s name replaces the first channel’s name in the right-hand  
corner, and the first channel’s name is instead displayed in one of the three remaining blocks at the bottom of  
the menu. See Figure 10-2.

10.3.3.C How to Make Your Session Persistent and Scrollable (Using History Mode)  
To make your session “persistent” (so that events are kept in memory even after they scroll off the screen) and  
“scrollable” (so that you can pull these retained off-screen events back onto the screen), press Alt-H after you  
open your session to start “history mode.” From that point on, the Card will retain the current session in  
memory even after events scroll beyond the top of the display, so that you can scroll backwards through the  
session at any time to check on what occurred earlier. While history mode is active, you can press an additional  
set of keys in order to scroll through the session log:  
CTRL-B to page up  
CTRL-F to page down  
K or – to move up one line  
J or + to move down one line  
1 then G to move to the home position (first line)  
G
to move to the end position (last line)  
If during your session you want to get out of history mode, press Esc (escape) to end it. It is deactivated  
automatically when you close your session.  
10.3.3.D How to Close a Session  
To close a session, make it the currently active session by pressing Alt-Tab until it is displayed on your monitor.  
Then press Alt-C. The session will close and the Options Screen will be displayed until you select another  
channel as active.

NOTES  
1. The “Chan” column lists the channel address of each component (Card or module). For Base Units, the option slot will  
always be listed as channel “M,” and the local-console module will always be listed as channel “N.”  
2. The “Card Type” column shows what type of component it is: “LCI”=Local-console module, “XPAC”=CPU-Interface Card,  
“XPLU”=Universal User-Interface Card, “XPDU”=User-Interface Card with On-Screen Display, “XPXT”=regular Transmit  
Card, “XPXR”=regular Receive Card, “XPST”=CAT5 Transmit Card, “XPSR”=CAT5 Receive Card, “XPIQ” = Management  
Card, and “XPSI” = Serial Control Card.  
3. The “HW Rev” column lists the revision level of the component’s hardware.  
4. The “EPROM FW Rev” column lists the revision level of the component’s original firmware (that is, the firmware burned into  
its EPROMs at the factory).  
5. The “FLASH FW Rev” column lists the revision level of the most recent firmware (if any) that has been downloaded to the  
component’s Flash ROMs.  
6. The “Serial #” column lists the component’s serial number. Unless the component is an eval, demo, or special unit, the serial  
number should always be numeric.  
7. The “Other Information” column shows the Switch’s best guess of what the component is attached to (if anything) based on  
the states of the ground leads of the component’s connector(s).  
8. What “* - Indicates active device” means is that the asterisk shows whether the component is running using the firmware in  
its EPROMs or the firmware in its Flash ROMs.

10.4.2 DISPLAY FLASH ROM STATUS  
When you choose option 2 from the main menu, you will be prompted to enter a channel address. Enter a  
remote address or leave the field blank for the local channel (that is, for the Management Card itself). The  
firmware type and current firmware-revision level of the selected Card—which can be any type of ServSwitch  
Multi Card—will be displayed as shown below.

The “Pos” column shows which “slot” in the Card’s memory a firmware program is stored in: Management  
Cards have nine of these, numbered 1 through 9; all other Cards have only one, numbered 1. The “Flash Type”  
indicates what type of Card the program is designed for—see Note 2 on the previous page for explanations of  
what these abbreviations mean—or says “Available” if the slot is empty. The “FW Rev” column indicates the  
revision level of the program, or says “–NA–” if (as is the case with the Management Card/XPIQ firmware in  
slot one) the firmware can’t be transmitted to any other Card.

10.4.3 DOWNLOAD LOCAL TO REMOTE FLASH ROM (CROSSLOAD FIRMWARE BETWEEN CARDS)  
If the main menu serial-port function is enabled (you can check this by selecting option 10), you can use  
option 3 to transfer firmware from the local Management Card to any other ServSwitch Multi Card in your  
system that you can transmit to. When you select this option, the local Management Card checks the firmware  
programs it has loaded in its memory, then displays descriptions of them on screen (see the last paragraph on  
the previous page for what each column means).

The Card then prompts you for the numbered slot in its Flash memory where the program you want to transfer  
is stored (the program in position 1 can’t be transferred to any other Card):  
Local Flash ROM number (2..9) [2]:  
Then the Card prompts you for the address of the Card that will be receiving the firmware program:  
Channel address [0-H]:  
Finally you’re prompted for the number of the slot in the other Card’s memory where you want that Card to  
store the program (“1” is the only valid option for any type of Card other than Management Cards):  
Remote Flash ROM (1..7) [1]:  
Type in the number of your desired slot or press [Enter] to accept the default value. As soon as you do so—  
provided the addresses and the file are all valid—the transfer begins. Depending on whether the transfer  
succeeds or not, one of these messages will be displayed:

10.4.7 TRANSFER SECURITY LOG  
To connect the Management Card to an IBM PC/AT or PS/2 compatible computer, you will need a PC/AT  
style null-modem cable such as our product code EYN257H. Attach one end of this cable to the Card’s  
DB9 male serial port and the other end to the computer’s serial port. Once this connection is made, choose  
option 8 to transmit the contents of the Management Card’s security log from the Card to that PC. Using a  
®
®
®
suitable terminal-emulation program (such as Microsoft Windows HyperTerminal™ or ProComm ), the  
security log can be captured to a file for printing and storing.  
When you select option 8 at the System Management Tools Main Menu, you will be asked to configure the  
Management Card’s serial port, as shown below: Either accept the default port settings or toggle among the  
different available values. (The receiving computer’s serial port must be configured the same way.) Then enter  
or accept the date and time of the first log record you want to transfer, and the log transfer will begin (make  
sure the terminal emulator is running on the receiving computer at this point). The data will be formatted the  
same way it is in the Log Window of the Management Card’s Security Monitor (see Section 10.5.3). Each line of  
ASCII text ends with carriage-return and line-feed codes.

10.4.8 TRANSFER CHANNEL LIST  
You can use the Serial Channel-List Menu to edit the local Management Card’s channel list in any of several  
ways (see Section 10.3.1). Once you finish making your desired changes, you can choose option 9 at the main  
menu in order to send the new and improved channel list to another Management Card elsewhere in your  
system—or to receive the list from another Card if there’s a better version elsewhere, or if changes you made to  
the local Card’s list turn out to have been mistaken. When you select this option, these lines will be displayed on  
the screen:

Press SPACE to change, ENTER to accept  
Transfer Option: Transmit  
You can can press [Enter] to accept the default “Transmit” option, so that the local Management Card sends its  
channel list to the remote Card, which replaces its own list with the local Card’s. Or you can toggle to “Receive,”  
so that the local Card overwrites its own list with the remote Card’s. Either way, you will be prompted for the  
address of the remote Card:  
Channel address [0-H]:  
As soon as you enter the address (chassis number followed by slot letter) of the remote Management Card, the  
transfer begins. You will receive one of these messages to indicate the result of the attempted transfer:  
Successfully completed  
Disconnected from remote  
Invalid remote password  
Remote channel busy  
No response from remote  
10.4.9 MAIN MENU SERIAL PORT ENABLE/DISABLE  
If you’re not going to be running a VT100 session on the Management Card’s serial port, you can run cable  
from it to a PC running terminal-emulation software such as HyperTerminal and access the Card’s System  
Management Tools Main Menu directly rather than through the User-Interface Card with On-Screen Display.  
To enable this kind of communication, choose option 10 at the Main Menu. These lines will appear:  
Current Main Menu serial port status is DISABLED.  
Press SPACE to change, ENTER to accept  
Press the spacebar to toggle the setting. This line appears:  
Main Menu serial port is currently ENABLED.  
At this point, you must press Enter to return to the System Management Tools Main Menu. Any terminal-  
emulating PC attached to the Management Card’s serial port will now be able to access this menu directly until  
this setting is switched back to DISABLED.

SERVSWITCH™ MULTI  
11.1.6 VIDEO CAN BE SEEN BUT IS SUPERIMPOSED ON ANOTHER COMPUTER’S VIDEO  
1. Make sure that no two ServSwitch Multis in your system are set to the same address.  
2. Make sure that all of the Expansion Cards in the system are plugged in completely and that their  
connecting screws are tight.  
11.1.7 VIDEO BLANKS OUT UNEXPECTEDLY  
1. Check your administrator timeout (see Section 9.3.2.A) and/or keyboard/mouse-inactivity timeout (see  
Section 4.2.2) and make sure that both are set properly.  
2. Make sure that neither your monitor, the selected computer, nor any of the ServSwitch Multis in between  
have lost power.  
3. Make sure that the video cabling between the monitor and the selected computer has not come loose or  
been cut somewhere.  
11.1.8 THE ON-SCREEN DISPLAY DOESN’T APPEAR  
1. Make sure that the User-Interface Card to which your console is attached is in fact a UICD rather than a  
UUIC.  
2. Try getting the Command-Line-Entry Window to appear (see Section 9.2.4); if you can, make sure that you  
don’t have menu activation turned OFF (see Section 9.2.3.B).  
3. If your monitor is not a multisync type, and if you haven’t already done so, enable the UICD’s non-  
multisync-monitor support (see Section 9.5).  
11.1.9 AN RS/6000 KEYBOARD IS NOT RESPONDING  
Some RS/6000 computers have difficulty if they’re connected to their keyboards through a ServSwitch Multi  
system. Temporarily uninstall the CPU-Interface Card that the RS/6000 is attached to. Find the jumper on the  
Card labeled “S5”; set this jumper to ON and reinstall the Card. If this doesn’t help, take the actions  
recommended in the next section.  
11.1.10 A KEYBOARD DOESN’T WORK  
1. Send the Command-Mode hotkey sequence (see Section 8.2.1) to the ServSwitch Multi from the keyboard.  
If this sends the Switch into Command Mode (the LED for your current channel should blink), at least the  
keyboard and Switch are communicating, so the problem is likely on the computer side; skip to step 5. If  
the Switch won’t go into command mode, go on to step 2.  
2. Make sure that the keyboard is completely and securely plugged into the User Cable, and that the User  
Cable is completely and securely plugged into the ServSwitch Multi. (If your User Cable is a PS/2 type,  
make sure that the keyboard and mouse strands haven’t been connected backwards at either end; the  
PS/2 mouse strand is marked with a yellow band.)  
3. If you have multiple keyboards attached to your local console or your secondary console’s User-Interface  
Card, the ServSwitch Multi doesn’t support this; you’ll have to remove all but one of the keyboards.  
4. Is Scroll Lock ON or OFF? This will determine which of two characters is sent to the selected computer  
when certain keys are pressed; see Section 8.4.  
5. Make sure the selected computer is plugged in, turned ON, and receiving adequate power.

backwards at either end; the PS/2 mouse strand is marked with a yellow band.)  
2. Make sure the selected computer is plugged in, turned ON, and receiving adequate power.  
3. Check the affected computer’s Server Cable. Make sure that all its connections, especially the strand that  
runs to the computer’s mouse port, are tight and secure. (If the affected mouse is PS/2 type and your  
Server Cable is PC type, make sure that the Server Cable’s PS/2 keyboard and mouse strands haven’t been  
connected backwards at either end; the PS/2 mouse strand is marked with a yellow band.)  
4. If you have multiple mice attached to your local console or your secondary console’s User-Interface Card,  
the ServSwitch Multi doesn’t support this; you’ll have to remove all but one of the mice.  
5. Send the “<CM>M+[Enter]” command from your console’s keyboard to re-enable the mouse (see the entry  
for this command in Section 8.15).  
6. Make sure that all of the Interface Cards and Expansion Cards in the system are plugged in completely

of each channel’s configuration information on the appropriate pages, and update this information whenever  
you make changes. If you need to contact Black Box Technical Support, have all this info on hand (and please  
fill out a copy of the Problem Report in Appendix B) before you call.  
The six pages from page 140 through page 145 are divided into six configuration charts, one chart for each  
type of configurable ServSwitch Multi add-in Card or Module. For the Cards, fill out one record in a copy of the  
appropriate chart for each channel that you’ve installed a given type of Card in: Chart A-1 for CPU-Interface  
Card channels, A-2 for User-Interface Card channels, A-3 for Expansion Transmit Card channels, or A-4 for  
Expansion Receive Card channels. For the Modules, fill out one whole chart for each Module: Chart A-5 for  
Transmit Modules or A-6 for Receive Modules.  
Remember that CPU-Interface Cards have HD44 connectors; User-Interface Cards have HD62 connectors;  
Transmit and Receive Cards have two HD26 or six RJ-45 connectors; Management Cards have DB9 connectors;  
and Serial Control Cards have four RJ-45 connectors. Channels are designated by letters on the front panel of  
the ServSwitch Multi; when the Switch is viewed from the rear, as shown in Figure A-1, the slot for channel A is  
on the far right, channel B’s slot is just to the left of channel A’s, and so on. On the left-hand end, the slots for  
letter-designated channels proceed through the one for channel N (for EXPs and SBs) or channel L (on Base  
Units) or channel D (on MXs). On Base Units, the next-to-the-leftmost slot is the “option slot” channel—call it  
“channel M”—and the leftmost slot always houses the local console—call it “channel N.” The leftmost slot on  
an MX always houses the local console also—call it “channel E.” (See Section 2.6.3 for a description of the  
naming conventions for channel slots on the ServSwitch Multi Base Unit and MX.)  
Channel M (option  
slot on Base Unit)  
Channel N (local-  
console module  
on Base Unit)  
Slots corresponding to lettered channels on  
all three of these ServSwitch Multi models

APPENDIX C: DIP-Switch Settings and Their Numeric Equivalents  
Appendix C: DIP-Switch Settings  
and Their Numeric Equivalents  
Table C-1 on the next page is useful for two purposes:  
1. If you need to override the physical setting of the DIP switch on the currently selected computer channel’s  
CPU-Interface Card (see Section 4.2), you can issue the “<CM>SW=n[Enter]” command (see Section 8.14)  
to do so, where n is the decimal number that equals the binary number that in turn corresponds to the  
desired DIP-switch setting (1 = ON, 0 = OFF). For example, suppose the Card is currently set to translate  
composite sync to H/V-sync for your monitor, to use a 1-second timeout, and to reverse the keyboard keys  
when it maps. The DIP switch would read, from left to right (position 8 through position 1), “OFF OFF  
OFF ON OFF OFF ON OFF”—00010010 binary. Now suppose you’ve swapped in a somewhat slower PC-  
compatible computer that outputs sync on green, and you want to alter the Card’s DIP-switch setting so  
that the Card translates sync on green to H/V-sync, uses a 10-second timeout, and does not reverse the  
keyboard keys. If you had to manually reset the DIP switch, it would read “OFF OFF OFF OFF ON OFF  
OFF ON”, 00001001 binary. Looking this up in Table C-1 shows you that this equals 9 decimal, so instead  
of removing the Card and fussing with it, you can just send it the “<CM>SW=9[Enter]” command.  
2. In a cascaded ServSwitch Multi system, all of the Expansion Transmit Cards in a given Switch must have  
their DIP switches set to the same unit address, and this address must be unique to that Switch. So if you  
want a new Switch you’re adding to the system to be unit 7, look up 7 decimal in Table C-1; it will show you  
that you should set the DIP switch to 00000111 binary, which corresponds to (left to right—position 8  
through position 1) “OFF OFF OFF OFF OFF ON ON ON.” Note that addresses 0 and 255 are reserved;  
do not set the Card to these addresses.

APPENDIX D: Cables  
D.3 Adapters  
In addition to the standard cabling, we offer a set of adapters that you can use to connect legacy equipment to  
the ServSwitch Multi system:  
• To attach a legacy monitor with a 13W3 video connector, plug an HD15 male to 13W3 video adapter cable  
into the user cable’s monitor strand: Use the 1-ft. (0.3-m) KV16SUN (13W3 female) for a Sun monitor, the  
5-ft. (1.5-m) KV16SGI-1 (13W3 male) for an SGI monitor, or the 1-ft. (0.3-m) KV16RS6-1 (13W3 female) for  
an RS/6000 monitor. (With Sun and RS/6000 monitors, attach the monitor’s own cable to the other side of  
the adapter. With SGI monitors, use the adapter cable instead of the monitor’s own cable—attach it to the  
video port on the monitor itself.)  
• To attach an legacy Mac monitor with a DB15 video connector, plug the 1-ft. (0.3-m) HD15 male to DB15  
male video adapter KV16MAC into the user cable’s monitor strand.  
• To attach a legacy monitor with three BNC connectors for RGB video, plug the HD15 male to triple BNC  
male video adapter cable KV16BNC into the user cable’s monitor strand. If you include the three 6.5"  
(16.5-cm) broken-out cable strands at its monitor end, this cable is 8.2 ft. (2.5 m) long.  
• To attach a legacy CPU with a 13W3 video connector, plug an HD15 female to 13W3 male video adapter  
cable into the CPU cable’s video strand: the 5-ft. (1.5-m) KV16SGI-2 for an SGI CPU or the 1-ft. (0.3-m)  
KV16RS6-2 for an RS/6000 CPU.  
Lastly, we also offer the Loopback Mouse Adapter KV16LOOP, which you’ll need in order to attach a CPU with  
dual video outputs to the ServSwitch Multi system with a PC type Server Cable (KV20xx or KV20xx-R2). This  
Adapter makes it possible for the ServSwitch Multi to recognize the secondary video connection as a valid CPU  
channel. Refer to Section 3.3.5.

SERVSWITCH™ MULTI  
Appendix E: Making Nonstandard  
Serial Connections  
The dedicated serial-device/serial-port connectors on the ServSwitch Multi’s User Cables and Server Cables  
support the EIA/TIA RS-232 interface, pinned out on DB9 according to TIA-574 (IBM PC/AT and PS/2  
compatible). This means that you’ll need adapters or interface converters to connect various types of serial  
devices and ports to these connectors:  
®
• Apple equipment: The serial ports of early Macintosh models, as well as older Apple LaserWriter Plus  
printers, have DB9 female connectors, but this is a proprietary EIA/TIA RS-422/423 interface rather than a  
standard RS-232 interface. You will need an interface converter to connect one of these to a ServSwitch  
Multi User or Server Cable. You will need an interface converter, and maybe special cabling too, to connect  
Macintosh type 8-pin mini-DIN RS-422/423 serial ports (such as those on Mac Plus computers and Image  
®
Writer II printers) to a User or Server Cable. We don’t recommend that you make connections like these; if  
you absolutely have to do so, call Black Box Technical Support.  
• Wrong-gender DB9 connectors: To connect a RS-232 serial device that has a DB9 male rather than a DB9 female  
connector to a User Cable, or to connect a computer’s RS-232 serial port that has a DB9 female rather than  
a DB9 male connector to a Server Cable, you will need a DB9 gender changer such as product code FA440.

• Other interfaces: To connect serial devices or ports designed for some other interface (EIA/TIA RS-530 or  
RS-449, ITU V.35 or X.21, etc.) to the ServSwitch Multi, you will need an interface converter. We don’t  
recommend that you make connections like these; if you absolutely have to do so, call Black Box Technical  
Support.

APPENDIX F: Rackmounting the Base Unit or EXP  
Appendix F:  
Rackmounting the Base Unit or EXP  
Use a ServSwitch Multi Rackmount Kit to mount a ServSwitch Multi Base Unit or EXP in a 19" rack: product  
code RMK19L for the Base Unit, RMK19LE for the EXP. (The ServSwitch Multi MX is not designed to be  
rackmounted; the ServSwitch Multi SB and Hub can be rackmounted right out of the box, without requiring  
extra hardware.) Each of these Kits consists of a rackmounting faceplate, two handles, and four screws. To use a  
Kit to mount a ServSwitch Multi, take these steps, referring to Figure F-1 on the next page:  
1. Use the four included screws to attach the handles to the ends of the rackmount faceplate.  
2. Remove the three screws that secure each side of the ServSwitch Multi’s cosmetic shell, as well as the four  
screws that secure the top of the shell. Then remove the shell. (If you might ever be using the Switch as a  
standalone unit again, save the shell and its screws; otherwise, do whatever you want to with them, because  
you will not be reusing them in the rackmounted setup.)  
3. Remove the four screws at the corners of the Switch’s faceplate. Keep these screws close by.  
4. Fit the rackmount faceplate over the Switch’s regular faceplate, aligning the holes in the corners of the  
rackmount faceplate with the holes in the corners of the regular faceplate  
5. Thread the screws that you removed in step 3 through the holes in each of the new faceplate’s four  
corners, back into the screwholes on the regular faceplate. Once you’ve partially threaded all four,  
completely tighten (but don’t overtighten) them.  
6. Once the rackmount assembly is ready, match the holes in the protruding ends of the faceplate to an  
appropriate set of matching holes on your equipment rack, then fasten the assembly to the rack using your  
own screws, bolts, or cage nuts (not included).
