Fig. 1 Rear View of original Console Server 3200 - notice Control Card to far right
The SCS3230 upgrade replaces the CONTROL card of the 3200 with a new 10/100 BaseT
NETWORK and CONTROL card which includes a Linux-based operating system, and also
replaces the NETWORK and TERMINAL cards of the 3200 with CHANNEL EXTENDER cards.
1.1 Quick Start
Overview of Upgrading from a CS3200 to a SCS3230 (all covered in this manual):
1. Backup the Database of your existing CS3200 System.
2. Obtain the SCS3230 Kit, which includes the cards, cables and this manual.
3. Locate the firmware updates for the DEVICE cards; they are stored in the /lci/bin
directory on the NETWORK/CONTROL card. You may also download the update files
from the Lightwave FTP site. DEVICE cards MUST be updates to Version 4.03 firmware.
4. Remove the CS3200 from service.
5. Remove the CONTROL card, the TERMINAL card(s) and the Network or 10/100 card(s)
6. Install the 3230's NETWORK/CONTROL card in place of the CONTROL card.
7. Install the four CHANNEL EXTENDERS in place of the TERMINAL or NETWORK cards.
8. Connect the four cables for the CHANNEL EXTENDERS.
9. Turn the System On, and administer the system using the TERM port. Set up your IP
network connection information to get that operating.
10. RESTORE your CS3200's database into the SCS3230 system.
The SCS3230 system should be fully operational at this point.

1.3 System Features
The SCS3230 system is a Linux-based Console Server offering secure IP network-based
connections to up to 32 connected devices via EIA-232 protocol. Linux administrators will find
familiar commands and should need little guidance on administering the SCS3230 to co-operate
in their server installation.
System users will not encounter any differences in operation. The commands and functions of
the SCS3230 are designed to minimize any conversion issues.
The SCS3230 offers the following important features (many of which are also found in the
CS3200 product):

128KB-per-port Buffer Memory for DEVICE ports
Front Panel multi-line backlit LCD display and pushbutton controls
128MB FLASH Memory, 128MB RAM
* Redundant Power Inputs (chassis dependant)
Optional Analog Modem for dial up access (non-secure)
Power Options: Universal AC (100-240V) or -48VDC
* Some early CS3200 Chassis employ a single AC Power Input module. The Power Module is
field-replaceable to provide redundant power capabilities, if required.
The SCS3230 is one of the most versatile network administration tools available today,
allowing as many as 17 simultaneous users to access up to 32connected devices via
the RS-232C serial protocol. Pull-down menus help users navigate through all the
functions of the SCS3230, creating an easy-to-use way to access system resources.
The SCS3230 consists of eight device card slots, two switch card slots, four access card slots,
one modem slot and one Network/Control slot. The power supply slot contains two independent
power supplies for redundant operation. The basic system consists of the power supply
module, two switch cards, the Network / Control card, and in most cases, four Channel Extender
Cards. The remaining card slots are populated according to the application requirements.
All system parameters are stored in non-volatile data flash memory. This data flash memory is
organized such that there is always a complete copy of all data. Typical stored information
includes the users’ identities, user passwords, port parameters (such as baud rate, device
name, etc.) and other system information. The data flash memory allow for a maximum of 200
user profiles to be stored, along with the parameters for all cards. System parameters may be
backed up and restored from a local serial connection.
An important feature of the SCS3230 is the ability to re-configure the system hardware and
software without turning off the power. The system boards have circuitry that allows them to be
'hot swapped' so the system may be expanded at any time while in use.
System updates can be accomplished via software upload to the system. For most updates, the
system need not be restarted or taken out of service. Some operations or updates (e.g.,
Network update) may require the network ports be restarted.

1.5.2 TERM Port (Console)
A Terminal port, or Console (labeled TERM) is available at the top RJ45 connector on the
NETWORK / CONTROL Card. This is an EIA-232-compliant terminal position, typically used for
System Administration purposes.
The TERM port on the NETWORK/CONTROL card is fixed at 9600 baud, 8 data bits, No Parity,
and one Stop bit (9600 / 8 / N / 1) and is a DCE device.The TERM port has a higher Terminal
priority than the 10/100 Network Port on this card, and can be used for forced logout of
abandoned or other undesirable connections.
1.6 Backup and Restore Commands
The SCS3230 system is fully compatible with the "Backup and Restore" capabilities of the
CS3200, so transferring your user database from your existing CS3200 into the new SCS3200
hardware is supported.

ConsoleServer 3200 System
Lightwave Communications
2: System Overview
For simplicity, we will discuss the features and capabilities of the SCS3230 as if it were a new
and different system, not merely an upgrade to a ConsoleServer 3200. The SCS3230 is
designed to operate as closely to the original ConsoleServer3200 as possible from a user's
perspective, but still provide the capabilities needed for the secure server environment.
Existing 3200 customers maintain their investment and can offer enhanced security and control
for their terminal server systems. Existing users will not require retraining since all commands
and features of the SCS3230 option are the same as found in the CS3200. Even the upgrade
process accepts the existing site database for rapid deployment of the SCS3230 equipment.
2.1 Connect Up to Thirty-two RS-232C Compatible Ports
The SCS3230 is plug-compatible with any RS-232C device, DTE or DCE. These include a
variety of network servers, routers, or any other LAN/WAN computers on the network.
Connections are made by routing the device signals through the switch cards to the appropriate
user interface port.
2.2 128K FIFO Audit Trail
The SCS3230 stores the equivalent of approximately 200 screens worth of data (128K) per
device port in a true FIFO buffer for each DEVICE port. This data may be viewed 'off-line' at
any time by users accessing the device port buffer.
Should more than 128K of data be received in a buffer, the oldest data will be discarded, in the
amount of the 'overflow'. By operating in this fashion, the most recent data is collected and the
largest amount of data that can be saved will be maintained.
2.3 Connections
The system is capable of 17 simultaneous full-duplex connections to the connected devices.
The administration functions may be accessed through a local serial connection or through a
network connection. The NETWORK / CONTROL card (with a full complement of four Channel
Extender cards) supports up to 16 users connections plus one connection to the administration
functions. The NETWORK / CONTROL card also provides one TERM port (for a System
Administrator's serial Console)
The TERMINAL cards (a 3200 access card) may be used for applications requiring additional
local serial terminals. Each Terminal Card is installed in place of one of the Channel Extender

SCS3230 System Administrator's Guide
cards. By reducing the number of Channel Extender ports, the maximum number of available
connections for 10/100 network access is reduced by four sessions for each Terminal Card
installed. Illustrations showing a mixture of Channel Extender cards and Terminal Cards are
found on pages 11 and 16 of this Guide.
An optional MODEM connection is also available, however its connections are not 'secure' and
its use is not recommended except in those instances when security will not be compromised by
dial-in access using the modem. The SCS3230's modem connection is not subject to the Linux
security controls of the other access ports.
2.4 Security Passwords
The System Administrator may define up to 200 user profiles. Each user is assigned a unique
password by the system administrator. The system forces the user to change the password the
first time the user attempts to connect to any servers. After the users have changed their
passwords, the system will not prompt for a change. The users change their passwords at
whatever interval they feel is necessary.
The operating system is subject to Linux security constraints, including sysadmin and root level
security. Users cannot access the sysadmin layer or the root layer of the system.
2.5 Interface
Interfaces to the DEVICE and TERMINAL cards are all RS-232C compliant. These ports are
configured through the TERM port on the NETWORK / CONTROL card using a local Console,
or via network connection through your TCP/IP network. All system access is password
protected.
Each DEVICE port and TERMINAL has settings for baud rate, stop bits, parity, number of data
bits, flow control, and port type (i.e., DTE or DCE). The TERM port (for your Console) on the
NETWORK / CONTROL card has a fixed data format of 9600 / 8/ N / 1, and DCE.
The NETWORK / CONTROL card connects over a network using TCP/IP on 10- or 100-baseT
at 10/100 Mbits (auto-negotiating). The 10/100 port on this card is assigned an IP address, a
subnet mask, a default gateway, and an optional secondary destination path by Console
configuration using the TERM port on this card during the initial setup of the system.
The optional MODEM card connects directly to a conventional modular phone jack (RJ11) to
interface with a telephone network. The sys admin may designate a modem initialization string,
or may use the default modem initialization string, which allows auto-answering on one ring. The
modem provides card-edge visual status indicators.
Note:For 'secure' installations, the Modem should not be used. Modem access is not
encrypted and/or secure and could allow unauthorized access to system information. However,
if modem access is limited to internal administrative access, the modem may provide an
additional means of system access in the event your network is down.

ConsoleServer 3200 System
Lightwave Communications
3: System Components
Each SCS3230 consists of three major components: the 3200 system chassis, 3200 DEVICE
cards, and 3200 access cards. The 'access cards' include the new 3230 NETWORK/CONTROL
card, which is the heart of the SCS3230 product, and makes it operate a bit differently.
Note: The 3200's NETWORK card and 10/100 Network card are NOT supported by the
SCS3230 NETWORK / CONTROL card. The NETWORK/CONTROL card incorporates its own
10/100 Network port.
3.1 3200 Chassis
The chassis contains a front-panel LCD for quick system information that is available at all
times. Two front panel buttons allow display selection and paging through displays (see
section 10.0 for more information).
The second major component of the chassis is the power supply module. This module contains
two independent supplies, each capable of sustaining the system should one supply fail or lose
its power input. The Power Supply module also incorporates the system fan. The AC power
module has two front-panel switches (one for each supply) with replaceable fuses in their IEC-
type connectors. The DC power module provides a single On/Off switch.
The third and last component of the chassis is the SWITCH card set. The switch cards connect
the access cards to the device cards, with a maximum of 17 simultaneous connections using all
available terminal, network, and modem ports.
3.1.1 Power Supply Module
The SCS3230 may be equipped with either an AC power module or a DC power module. The
power module may be field-swapped (although is not hot-swappable) if the available power
source requirements change.
The Power Module provides two discrete electrical inputs to the system. Either power input
supports a fully-loaded chassis, and switching between power inputs is automatic if one source
fails or is turned off.
3.1.2 3200 Switch Cards
Two 3200 SWITCH Cards are required, and are unchanged from the 3200 system.

SCS3230 System Administrator's Guide
3.2 Device Cards
The Device cards are fully compatible with the SCS3230 application. The SCS3230 requires
version 4.03 Build 01 (or higher) of the Device Card binary firmware. Firmware updates are
downloadable from the Lightwave FTP site (ftp://ftp.lightwavecom.com).
Note: DEVICE CARD firmware MUST be updated to 4.03 or higher
Each DEVICE card has four completely independent ports for attachment to servers or other
devices with console ports. Eight device cards may be installed per system, for a maximum of
32 device ports. The device ports do not send an 'break' signal to the attached servers at any
time unless specified by the user. There are no adjustments directly on the device cards. All
parameters are set up through the system administrator port.
3.3 Access Cards
The card configuration is changed with the SCS3230, compared to CS3200.
3.3.1 NETWORK / CONTROL Card
The NETWORK / CONTROL card allows
users to connect to the device cards from
an SSH or telnet session over an IP
network, and remote access to the
administration functions.
The NETWORK
/
CONTROL card
replaces the CONTROL card from the
CS3200, and is located in the far right slot
of the system chassis. Only one card is
required in an SCS3230.
The NETWORK
/
CONTROL card
includes one TERM connector for a local
Console; one 10/100 NET connector for a
TCP/IP network interface, and four
CHANNEL EXTENDER ports. The
Channel Extender ports are connected by
RJ45 cables to one to four CHANNEL
EXTENDER cards, which are an
extension of the NETWORK card's
operation.
The NETWORK / CONTROL card
supports up to sixteen simultaneous user
telnet connections and one administrator connection to the same IP address. The network card
must be connected to a network that uses TCP/IP.

ConsoleServer 3200 System
Lightwave Communications
3.3.2 CHANNEL EXTENDER Cards
CHANNEL EXTENDER cards are used to extend the NETWORK functionality of the
NETWORK / CONTROL card, providing network access to the DEVICE ports in the system.
The Channel Extenders provide additional circuits allowing more simultaneous network
sessions, up to the system capacity of 16 device sessions. Channel Extenders are installed in
slots B, C, D, and slot E, replacing the NETWORK cards and the TERMINAL cards in a 3200
system.
The SCS3230 is normally configured with four CHANNEL EXTENDERS, but may have any
combination of CHANNEL EXTENDER cards and TERMINAL cards, as required for your
application.
Note:At least one Channel Extender card is required if any DEVICE access is required using
your IP Network.
CHANNEL EXTENDER cards connect to the NETWORK / CONTROL card using a short RJ45
cable. Each CHANNEL EXTENDER provides up to four (4) simultaneous sessions for DEVICE
port access over the IP Network connection.
3.3.3 TERMINAL Cards
The TERMINAL card provides a point of connection for a conventional RS-232 terminal or a
computer running a terminal emulation program. Users connected through a TERMINAL card
may connect to any of the device cards in the system, provided that their user profile has
access rights for the port. There are four ports per terminal card. Each port‘s parameters are set
up independently from the other ports. All parameters are set up through the system
administrator port. There is no access to the administration functions through the terminal card.
The SCS3230 may have up to 3 Terminal cards, depending on system requirements. In some
applications, the existing Terminal Card may be required for local serial connection to one of the
Device Ports. The existing Terminal Card is compatible and may be used, however the use of
each Terminal Card(s) reduces the number of simultaneous Network connections (by 4
sessions) that may be made over the new 10/100 Network port on the Network Control Card.
The 3200 Terminal cards offer configurable port parameters (baud rate, DTE/DCE, etc.), unlike
the fixed parameters of the TERM (Console) port on the NETWORK / CONTROL card.
The SCS3230 requires version 4.00 (or higher) of the Terminal Card binary firmware (fterm.bin).
This is not specific to 3230, and has been available for some time. Firmware updates are
downloadable from the Lightwave FTP site (ftp://ftp.lightwavecom.com).
3.3.4 3200 Network Cards
The earlier 3200 Network card (10baseT) is not supported by the 3230 Network / Control Card.
It will not function if installed.

3.3.5 3200 10/100 Network Cards
The earlier 3200 10/100 Network card is not supported by the 3230 Network / Control Card.
It will not function if installed.
3.3.6 Modem Card
The Modem Card is used primarily in the Console Server 3200 systems, however, it does not
provide or support any of the "secure" features of the SCS3230 system. It is not secure in the
sense that the modem circuitry is not subject to the encryption used for secure SSH
transactions, a primary reason for updating to the SCS3230. For this reason, the use of the
modem may be limited, or the modem may simply be disabled or removed, depending on your
site's application.
The modem card allows non-secure dial-in access to the SCS3230 and the servers attached to
its device ports. The modem card supports baud rates up to 38.4 kbps, and will auto-detect the
actual connection speed. Only one user at a time may access through the modem card, and
only one modem card may be installed per unit. The system administration functions may not
be accessed from the modem card.

ConsoleServer 3200 System
Lightwave Communications
4: Installation Instructions
Two options for your installation exist:
·
·
you are either UPGRADING a CS3200 system to be an SCS3230 system, or
you are installing a NEW SCS3230 system.
For simplicity, we will refer to a ConsoleServer 3200 system with the NETWORK/CONTROL
card installed as a SCS3220 system. In either case above, you will use THIS GUIDE for
administering the SCS3230 features and options, while referring to the ConsoleServer 3200
manual for a majority of the hardware installation instructions.
·
·
When you purchase a CS3200 chassis, you will get the CS3200 manual (PN 15.00.017).
When you purchase a SCS3230 NETWORK/CONTROL card, you will get the SCS3230
System Administrator's Guide (this manual, PN 15.00.038).
NOTE: The majority of this System Administrator's Guide is intended for the administration and
setup of the system, when using the SCS3230 kit. The hardware of the ConsoleServer 3200
may have been previously installed and is being upgraded at this time, or the system may be
installed as brand new installation.
Many hardware installation details are discussed in the ConsoleServer 3200 System Manual.
Not all are repeated in this manual.
4.1 Items in a SCS3230 Kit
The SCS3230 'kit' includes all of the cards and cables required to upgrade a CS3200 to the
SCS3230.
PN 500.000.0010 - 10/100 BT SECURE 3230 CARD KIT

Orders with a large number of cables and adapters are usually shipped in separate containers.
If you are updating a CS3200 system, you may want to save your existing database from the
CS3200 and copy it into the SCS3230. To do so, you will use Backup to save the database,
and then Restore to copy it into the SCS3230's memory.

SCS3230 System Administrator's Guide
4.2 Move Database from your CS3200 to SCS3230
The SCS3230 is designed to work with the Backup and Restore options found in the CS3200
product. You can transfer your database from the CS3200 to the SCS3230. To accomplish this,
you must save the Backup the system database to a local PC, and then after upgrading the
hardware, you can then upload the saved information.
If you do not use Backup and Restore, you will have to re-program the system with port and
user information.
This section assumes some existing familiarity with the administration methods (logging in,
using the TERM port, etc.) of the CS3200 system, much of which will be similar with the
SCS3230 system.
4.2.1 Backup Procedure of your CS3200 System
Before shutting down the CS3200 System, you should backup the existing user database. This
is a normal CS3200 operation, as described in the 3200 documentation.
1. Log in as the sys admin on Control card port Aon the CS3200's CONTROL card.
2. Make sure that there are no users logged in to the ConsoleServer 3200. If there are
any, have them log out or force them off the system using the FORCELOGOUTcommand.
3. In the communications program, begin the text file capture. Name the text file as
something that will indicate that it is the ConsoleServer 3200 parameters backup file, not
just a plain text file (i.e., 3200.bakand not 3200.txt).
4. Type the command BACKUPat the sys admin>prompt and press <ENTER>. Text will
be outputted to the screen; this text is equivalent to the binary data stored in the
ConsoleServer 3200's non-volatile memory. Wait several minutes while the
ConsoleServer searches memory for all non-zero records (unused records are skipped
in the backup).
5. After the sys admin>prompt returns, end the text file capture in the communications
program.
6. Open the text file with a text editor (such as Window's Notepad text editor, or StarOffice,
etc.).
7. Remove any text after but not including the line $BACKUP COMPLETE. DO NOT EDIT
ANY OF THE TEXT ABOVE THIS LINE! It is not necessary to remove the text after
$BACKUP COMPLETE, but it reduces the download time for the file during the RESTORE
process.
4.2.2 Restore Procedure
After the SCS3230 system is operational, you can transfer your CS3200 database into the
system using the RESTORE option. After your database is saved in the SCS3230 system, you
can backup and restore the SCS3230's user database using Backup and Restore.
1. Log in as the sys admin on TERM port on the NETWORK / CONTROL card.
2. Make sure that there are no users logged in to the SCS3230. If any users are currently
logged on, have them log out or force them off the system by using the FORCELOGOUT
command.

3. At the sys admin> prompt, type RESTORE and press <ENTER>. The SCS3230 will
prompt for confirmation to proceed with the parameter restore process. Type YES and
press <ENTER> to proceed. The system will ask for a second confirmation to proceed.
Type YES and <ENTER> to start the parameter restore process. After the second
confirmation, there is no text echoed to the screen indicating that the restore process is
proceeding.
4. Using the communications program, send the text file containing the backup records to
the SCS3230. Be sure to use text mode when transferring the file. The file download
should not take too much time; less than a minute is typical at 38.4K baud. After the
download is complete, the SCS3230 will re-zero all unused records. If a problem is
encountered during the text file transfer, the SCS3230 will abort the restore process and
return to the sys admin> prompt.
5. Once all unused records have been re-zeroed, the SCS3230 will reboot. Allow the
complete memory check to proceed; after it is done, log in as the sys admin at the
LCI3200> prompt.
6. The ConsoleServer is restored to its previous settings and is ready for use. Check that
all user, terminal, device, and other parameters are correct and acceptable.
4.2.3 To RESTORE from a 3200 to a 3230
Use a terminal emulation software on a PC connected to the sysadmin port of a 3200. Ensure
that software flow control (XON/XOFF) is turned on for the software.
1. Implement a capture to file.
2. type “backup”.
3. Wait until you see “$BACKUP COMPLETE”
4. edit the backup file and remove any information before the line which starts 0,… This is
probably the first line. Also remove the couple of lines that say $BACKUP COMPLETE. After
the backup there will be some extraneous information, this needs to be removed.
Copy the file to the 3230. This can be accomplished using pscp or scp
Log in to the 3230 and establish yourself as root.
Cd to /lci/bin
Step 1) Type ‘restore “file name” yes’
“file name” is the name of the file you just copied.
The last yes is needed if you want to be told what passwords the system is inserting for this
user. If you do not want to see the passwords, do not type anything.
Unless there is an issue, you will observe users being added to the system and any changes
that take place to the user name or password. If you receive a message about record number
being incorrect, the file is either corrupt from flow control or you have not edited out the
extraneous information that is in the file from doing the backup.
If the service multidrop is running you will be asked to stop it and told how to do so ‘type
“service multidrop stop”’. Goto step 1.

4.2.4 LCI Update
There are four binary (.bin) files in the /lci/bin directory of the Network/Control card that may be
needed to update existing 3200 cards for use with the new Network/Control card's firmware:
-
-
-
-
fterm.bin
rterm.bin
fdevice.bin
rdevice.bin
These files are stored on the Network/Control Card in the /lci/bin directory on the card. The files
customer will use the lciupdate program to install these updates, however, they do not need to
transfer the binary files from an external computer to the 3200 - they should just direct
lciupdate to use the /lci/bin path.
It is not necessary to update the Device or Terminal cards before assembling the system,
however, before the system is put into service, the cards should be updated.
To Update a Card or Cards
From the 3230 bash shell, type the following.
[If you are in the sysadmin shell on a 3230, type ‘exit’ to get to the 3230 bash shell.]
·
·
·
·
Establish yourself as super user
Type ‘service multidrop stop’
Type ‘ps –ax’ and look for any processes that contain the title multdrop.
If any multidrop processes exist, type ‘killall multidrop’. Type ps-ax and again look for
any multidrop processes. If there are any, type ‘kill –9 “the number in the farthest left
column on the same line as the process”’, do this for all multidrop processes.
Type lsmod and look for mdser. If mdser is not present type insmod mdser.
If you wish to change the card binary file (*.bin) stored on the SCS3230, copy the update
file (filename.bin) to the 3230 and place in the “/lci/bin” directory.
Type ‘/lci/bin/lci_update “[card letter][processor number]” file’. Where file is the name of
the file you for the slot you are updating. For instance you would probably type
/lci/bin/lci_update b1 fterm.bin for terminal cards (the file name may be different and b
could be b,c,d,e)
·
·
·
·
·
·
/lci/bin/lci_update h1 fdevice.bin for device cards (the file name may be different and h
could be h,I,j,k,l,m,n,o)
The processor number is relevant to multiprocessor cards. You will be informed if it is
anything other than one.

4.3 Connecting to the TERM Port
The cable kit P/N 200.0135 contains the necessary adapters to interface the system TERMport
on the NETWORK / CONTROL card to a laptop or a terminal. Using the adapters in the kit,
follow the steps outlined below.
The communications settings for the system administrator port (TERM) are fixed at 9600 baud,
one stop bit, no parity, eight data bits, and DCE (9600 8N1 DCE).
NOTE: The administration functions may also be reached via telnet. However, it is first
necessary to configure the network ports through the direct serial connection.
1.
Turn on power to the terminal or computer. If using a computer, start the desired
communication program. The terminal or communications program used must
be in VT100 emulation mode. Note that the VT100 functions keys are not always
mapped to the terminal or computer function keys; consult the appropriate
documentation for further information.
2.
3.
Ensure that the communications settings of your Terminal are correct.
Locate the serial port on the terminal or computer and determine what type of
connector is used. The cable kit included with theSCS3230 contains each of the
following: one RJ45 serial cable, an RJ45 to male DB9 adapter, an RJ45 to
female DB9 adapter, an RJ45 to male DB25 adapter, and an RJ45 to female
DB25 adapter. Select the appropriate adapter for the serial port on the terminal
or computer.
4.
5.
Firmly seat the adapter in the serial port. Screw down the adapter to secure it to
the serial port.
Insert one end of the serial cable into the adapter until a click is heard. Insert the
other end of the serial cable into TERM port of the NETWORK / CONTROL card,
again until a click is heard.
6.
7.
Press <ENTER>on the keyboard. Thelogin> (using Telnet) or login as: >
(using SSH) prompt should appear. If not, check that the SCS3230 is connected
to the appropriate power outlet, the power switch is on, the cards are firmly
seated, and that all cable connections are secure. If "garbage" characters
appear on the screen, check that the communications settings are correct.
The system administrator may now login to the system.

5: Connecting Equipment to the SCS3230
When connecting devices to the SCS3230, be sure to use Lightwave Communications
cables and adapters to ensure the proper transmission of data signals. If a device has
an RJ45 serial port, use the manufacturer's cable included with the equipment to
convert the RJ45 serial connector to a DB9 or DB25 connector, and then use a
Lightwave Communications adapter to convert back to RJ45 to attach to the device
port. Directly connecting the RJ45 port on the SCS3230 to the RJ45 port on a third-
party device may not allow for the proper transmission of data signals.

5.4 Device Card
NOTE: DEVICE Cards MUST be updated to Version 4.03 (or higher) firmware for SCS3230
The SCS3230 is designed so that the default device port communications settings will match
the communications settings of most Sun® server and workstation console ports (9600 baud, 8
data bits, no parity, one stop bit). Other equipment types (i.e., Cisco®) frequently use similar
communications settings; check the manuals included with the equipment for the correct
settings. The table below lists the default serial port communications settings for the SCS3230.
Sections 6.3 and 6.4 outline the commands for changing the terminal and device port
communications settings.
The following tables list the adapter part number and port configuration for some common
equipment types that may be connected to the SCS3230. Note that in some cases, an
additional cable or adapter is included with the equipment to convert a proprietary pinout to an
EIA-standard pinout. Also, note that it is not possible to connect the RJ45 serial port of the
ConsoleServer directly to the RJ45 serial port of any third-party equipment. Sun Netra
servers, Cisco switches, and other similar devices require a special adapter or cable to connect
to the ConsoleServer. The adapter or cable is usually provided by the manufacturer of the
equipment (e.g., Sun), or may need to be created by the user. The adapters and cables from
the equipment manufacturer are usually designed to interface directly to a terminal, so the
ConsoleServer device port must be configured as DTE rather than its default value of DCE.
Lightwave Communications has pre-made adapters and kits for some common equipment
types; contact Lightwave for information regarding your specific application.
Note:Some adapters are also available in quantity packs, and may be shipped under a different
part number. Quantity packs are "299.xxxx" compared to "200.xxxx".

6: SCS3230 Setup Script and
System Administration
The SCS3230 uses a script file to assist in the initial setup and configuration of the 3230
system. The script is intended for the first time the unit is turned on, in order to get the system
'up and running' as quickly as possible.
Note:In some of the following screens, the term "3220" may be found in place of the "3230"
which is found in the actual screens of the SCS3230 system.
The following section outlines the administration functions and commands.
The administration functions and commands are designed to enable the administrator to
configure the SCS3230 to fit the needs of the system application. User IDs, devices, terminals
and access rights may be configured using the administration commands.
Many commands may be abbreviated to one extent or another, but some may not be
abbreviated at all. For example, the command VERSIONmay be abbreviated to VER, but
LCIUPDATEmay not be abbreviated. See Appendix E for more information regarding
abbreviations.

prompt. Pressing <CTRL>+Rat the LCI3200>or sys admin>prompt will discard the
characters on the current command line, and retype the last command used; <ENTER>must still
be pressed to execute the command. Pressing <CTRL>+Uat either prompt erases the current
command line back to the prompt.
6.1 Power-up Sequence and
Basic Use of the Administrator Functions
NOTE: When the system is first turned on, it may take as long as 90 seconds before the front
panel display will show any activity, and before the system will 'wake up'. Total boot-up time is
generally about 3 minutes.
When the SCS3230 is first installed and powered up, it must be configured through the serial
terminal port. Connect the terminal port to a terminal device or computer using a terminal
emulation program. After the network interface has been configured, the administration login
may also be reached via telnet. All the functions available from a local serial connection (with
the exception of BACKUPand RESTORE) are also available through telnet by connecting to port
5000 of a ConsoleServer’s network IP address.
The serial terminal will display the following text at power-up:

The power-on self-test may be skipped by pressing<ESC> <ESC>or <CTRL>+C, but
the SCS3230 should be allowed to complete the POST if possible (this check usually
takes about three minutes). This information is not available on a network connection,
as it is not possible to connect to the ConsoleServer via telnet until the power-on self-
test is complete. At the completion of the power-up sequence, the administrator is
logged out, as indicated by theLCI3200>>prompt. Some commands may be used
from this prompt, but most are available only when logged in.
NOTE: The administrator may define the system prompt using the PROMPTcommand (see
section 6.11), but the system default prompt (LCI3200>>) is used in this guide for clarity.

6.2 Sys Admin vs. root access
The System Administrator (sys admin) has the ability to run the sysadmin functions of the
system. In order to run the Setup command, the System Administrator must change to the root
user. Below is a list of commands accessible by the different admin levels:
The Sys Admin must sign on, and then switch to root level (requires root password) so that they
may run the Setup command. The default root password is 'root'. This root password should be
changed as soon as the System Administrator has gained access to the system.
To Change the root-level password of the SCS3230, follow the steps below.
1. Log in as sysadmin(you see the bash prompt) = sysadmin@SCS3230 /tmp$
2. suto root level; you must enter the existing root password (default = root)
3. After password is accepted, notice root level = root@SCS3230 /var/tmp#
4. Use passwdto change root level password
5. After successful, 'authentication tokens updated' message is displayed. You are
returned to the root level prompt = root@SCS3230 /var/tmp#
6. Use exitto leave root level (sysadmin@SCS3230 /tmp$)
7. Use logoutto log out of the system
If you lose the root password, there is no 'back door' password or higher-level access. The
Flash memory device would have to be replaced in order to regain access to the system. Your
existing data on that Flash device would be inacessible.
Only the root level password has access to the SAVE feature which can invoke permanent
changes to the system's memory and features. Turn the system power off without using SAVE
will cause any system changes to be lost.

The System will run through the system configuration and make the appropriate changes. Note
that some commands may show a 'fail' which may be normal for that instance. A 'fail' message
may mean that a command was not previously running, and so the command to kill that
application 'failed' (because it wasn't running). However, if you review the operations at a later
time, you will probably see an 'OK' message for the same prompts and options.
THE VERY FIRST TIME the System is run, the Setup script will automatically undergo a reset

7: Creating and Managing Users
7.1 Adding a User ID
The ADDUSERcommand creates user IDs and assigns initial privileges. The following
screen will be displayed when the command is used:
sys admin>>ADDUSER
Number of available user records: 200
Number of users defined: 0
Enter user id | USER ID >
Press <ENTER>after typing the user ID. The user name is not case-sensitive. The next prompt
asks for a password for the user ID. When the user logs in for the first time he will be asked for
this password. This password is case-sensitive and is pre-expired. The user must change the
password before accessing any of the SCS3230 device ports. The user password may be up to
10 alphanumeric characters long, and may not contain the “*” character. The SCS3230 will
echo only stars when the sys admin enters the password and confirmation
Enter case sensitive password | PASSWORD > ****
Re-enter case sensitive password | PASSWORD > ****
0-17 | MAX CONCURRENT LOGINS: 1>17
This parameter limits the number of simultaneous logins a user may have. The sys
admin may select between 0 and 17 concurrent logins. A user with 0 logins will have
connect and listen permissions defined, but cannot login to access anything until a
number of logins greater than 0 is defined.
Allowed devices example: 1-5,10 | DEVICES 0 > 1,5,7,8,30
Allowed listen devices example: 1-5,10 | DEVICES 0 > 1-32
The sys admin is now prompted to define the device ports that the user will be allowed
to access for direct connections and listening connections. If more than one port is to
be allowed, then the individual ports must be separated by a comma. A range of ports
may be specified using the dash (“-“).

Allowed devicesdetermines which devices a user may select for direct access.
Allowed listen devicesdetermines which devices a user may use listen access.
“Listening” is defined as being able to read from an existing device port connection
without write ability. This feature is useful for sharing information among multiple users
or for monitoring a user’s session with an attached device.
Fig. 4 Device Port Numbering
HELPFUL HINT: Make a diagram or spreadsheet of connections indicating connections
between devices and theSCS3230 device ports as numbered above.
The Allow user to clear device buffer (Y/N) | YES >option determines
whether a user may use the CLEARcommand to delete all the data stored in a device
port FIFO buffer. The sys admin may want to inhibit this ability to preserve user
accountability when accessing attached devices. Users are allowed to clear buffers by
default. Pressing <ENTER>will allow the user to clear the buffer; typingNOand then
pressing <ENTER>at the prompt when defining a user ID will disallow the user from
clearing all device buffers.
The Clear screen after a command (Y/N) | YES >option determines if the
screen clears when most commands are executed. Disallowing this screen behavior
keeps the last few commands and responses on the terminal screen. The default value
for this option is YES. Pressing <ENTER>will accept the default value; typing NOand
then pressing <ENTER>disallows this screen behavior.

sys admin>>
To edit or change parameters for a particular user after defining that user ID, use the
EDITUSERcommand. For example, if the user 'Tom' needed to have more concurrent
login capabilities, the sys admin would typeEDITUSER TOMon the command line. As
each line comes up, change the settings and press <ENTER>, or press <ENTER>to
accept the current setting.
NOTE: When editing any group of parameters, pressing the <ENTER>key will accept
the current value and move to the next parameter in the list.
7.3 Listing User IDs

7.4 Deleting a User ID
To delete a user, use theDELETEUSERcommand, followed by the user ID on the same
line. The LISTUSERScommand will allow verification after deleting a user ID. The
following command sequence is an example of the use of DELETEUSERwith
LISTUSERS:
sys admin>>DELETEUSER PETE
Delete user:pete
Yes or No (N):y
sys admin>>listusers
2: User id > KEVIN
3: User id > TONY
sys admin>>
User IDs may also be deleted by their record number. As each user ID is created, it is assigned
a sequential record number. This number is associated with the user ID and will be displayed
using the LISTUSERcommand.
sys admin>> deleteuser /3
Delete user:tony
Yes or No (N):y
sys admin>>
To delete a user ID using the record number, specify the number as a qualifier after the
DELETEUSERcommand in the form DELETEUSER /N, where Nis the user record number.

Device port parameters must be defined by the sys admin using the DEVICES
command. If a single device port is to be changed, the port number must follow the
DEVICEScommand. If the DEVICEScommand is entered by itself, the configuration of
all device ports will be listed. To edit all possible device ports for a unit, enter the
command DEVICES /ALL.
Programmable elements include: device name, baud rate, stop bits, parity, data bits,
DCE/DTE, flow control and inhibit direct mode. Pressing<ENTER>accepts the
parameter as is. If changes need to be made, each parameter may be edited as it
comes up after each >prompt.
The device name may not contain the *character. If a name is entered with this
character, the administrator will be asked to re-enter the name.

Lightwave Communications
Four baud rates are offered: 9600, 19200, 38400, and 57600. Most devices use 9600
as the console/admin port baud rate, so the device port defaults to this value. Check
the equipment documentation for the proper baud rate.
The format of the bit-wise transmission of data is determined by the stop bits, parity,
and data bits parameters. The default settings are 1 stop bit, no parity, and 8 data bits.
Check the equipment documentation for the proper settings.
Each device port may be separately configured as either DCE or DTE. The DCE setting
is used when connecting to a DTE device such as a computer. The DTE setting is used
when connecting to a DCE device such as a managed switch. The device ports are
configured as DCE by default.
The device port flow control settingdetermines the method of flow control. The two
most common settings are XON/XOFF (a.k.a. software) and RTS/CTS (a.k.a.
hardware). DTR/DSR is used very infrequently. The default setting for the device ports
is XON/XOFF. Check the equipment documentation for the correct flow control setting.
The INHIBIT DIRECT MODEsetting allows the administrator to turn off port buffering
while a user is connected to the device and is in direct mode. The device port buffer still
collects data while not in direct mode when this setting is active. It may be desirable to
disable direct mode buffering so sensitive data is not viewable by other users, but alert
and panic messages from the attached device are still stored when nobody is
connected. This setting is disabled by default, so buffer data is collected both in and out
of direct mode.

The sys admin defines terminal port parameters using theTERMINALScommand in a
manner similar to the DEVICEScommand. If the command is entered by itself, the
terminal settings will display. If the terminal port number is specified after the

7.7 Network Commands
The NETWORK command setup is changed, if compared to the CS3200 system.
The NETWORK or access ports in chassis slots B, C, D and E are connected to the
CONTROL/NETWORK card using CHANNEL EXTENDER cards. All chassis backplane
Network ports are accessed through the 10/100 IP network port on the CONTROL/NETWORK
card.
When used without qualifiers, the NETWORKcommand will display the network settings assigned
to each card slot. The IP address, subnet mask, default gateway, secondary route, and bootp
settings are displayed for each slot. These parameters are assigned to the slots rather than the
cards. If a network card is moved from one slot to another, it will have the parameters assigned
to its new slot rather than those previously assigned to it.
When used with the /ALLqualifier, the NETWORKcommand will allow the system administrator
to change the network parameters for all the card slots in order. The sys admin will be
prompted to enter the IP address, subnet mask, default gateway, secondary route, and bootp
settings for each card slot. If <ENTER>is pressed at the prompt, the value displayed in the
prompt will be used. After entering the parameters for each slot, the sys admin will be asked if
the new parameters should be used. If NOis entered (or just <ENTER>is pressed), then the
previously entered changes will be discarded and the system will move on to the next slot’s
parameters. If YESis entered, then the slot’s network parameters will update in control card
memory and the control card will send the new parameters immediately to the card in that slot.

ConsoleServer 3200 System
Lightwave Communications
If the card is a network card, it will immediately acquire the new network parameters and
disconnect all telnet sessions to that card. If a terminal card is in the slot, or if the slot is empty,
the network parameter update is refused, but the network parameters for that slot will be saved
to control card memory.
When the NETWORKcommand is used with a card slot letter as a command qualifier, it will
attempt to change the parameters only for that card slot. In all other aspects, the command
behaves the same as if the /ALLqualifier was used.
If a bootp server is present on the same network as the SCS3230 network card and bootp is
enabled on the network card, then the network card will use the IP address and subnet mask
assigned by the bootp server rather than those assigned by the sys admin.
Once a network card has been assigned an IP address either by a bootp server or by the sys
admin, then the ConsoleServer may be accessed by telnet. Connecting to the default telnet
port reaches the user login; connecting to port 5000 reaches the sys admin login.
7.8 Modem Command
The MODEMcommand allows manipulation of the modem card initialization string. When the
command is entered, the sys admin is prompted for the new initialization string. Typing a new
initialization string and pressing <ENTER>will create a new initialization string for the modem,
while just pressing <ENTER>will accept the current value. After pressing <ENTER>, the sys
admin is asked to confirm the changes to send the string to the modem. Typing YESand
<ENTER>will send the initialization string immediately to the modem card, while typing NOand
<ENTER>discards the entered initialization string and keeps the old string. If the modem card is
not currently installed, the settings are not sent, but are kept in control card memory. The
control card will send those settings in memory when a modem card is installed.
sys admin>>MODEM
Enter accepts present value
Init string | > ATB2H0
Save changes and update modem card? Yes or No: No>yes
Modem card not installed in slot A, init string saved

Current modem init string is: ATB2H0
Set modem to factory default value of: ATH0S0=1
(write out YES) Yes or No: No>yes
Modem card not installed in slot A, init string saved
sys admin>>
The sys admin may also reset the initialization string to the default value by entering the
command with the default qualifier in the form MODEM /DEFAULT. When using the /DEFAULT
qualifier, the current initialization string is displayed, along with the factory default string. The
sys admin is asked to confirm the use of the default modem string; typing YESand <ENTER>will
send the default initialization string immediately to the modem card, while typing NOand
<ENTER>keeps the old modem string.

SCS3230 System Administrator's Guide
It is recommended that the default modem initialization string be used unless the application
requires that it be changed. The default initialization string is ATH0S0=1, which disconnects any
active phone connections when the initialization string is sent, and sets the modem to auto-
answer on one ring.
7.9 Status Commands
There are six commands which allow the sys admin to check the status of the
SCS3230: CONNECTIONS, LISTCARDS, VERSION, INFO, POWERSTATUSand LOG.
7.9.1 CONNECTIONS Command
The sys admin may monitor the status of connections made through the terminal cards
by using the CONNECTIONScommand. This command will display all the active
connections and the mode of those connections as follows:

The above example shows that user KEVIN is logged in on terminal port 01, is
connected to device port 01 (which is named "Server" in theSCS3230), and is in
monitor mode. The list will display the user ID of any logged-in users, the device port to
which they are connected, the device name assigned to that port, and the mode of that
connection (see sections 7.8, 7.9, and 7.10 for an explanation of the various connection
modes). If the user is not connected to any device, they shall simply be listed as "User
Logged-In".
When used with the /MONITORcommand line qualifier, the CONNECTIONScommand
updates the connection list on screen every time a user logs in or out or changes login level
(i.e., goes into direct mode), rather than simply displaying the list once as occurs when the

CONNECTIONScommand is used alone. (See section 6.8, Sys Admin Session Management
Commands).
The CONNECTIONScommand will also tell the sys admin which terminal ports are
present (in the list, they are referred to as "channels"). If the port is not functioning (i.e.,
the card is not present or there is a fault with the individual port), the port will be listed
as "<not installed>". It will also list Telnet Active for an active Telnet session.
7.9.2 LISTCARDS Command
Sys admin>>LISTCARDS
Installed cards
Slot A : <card not installed>
Slot B : Terminal card installed
Slot C : Terminal card installed
Slot D : Terminal card installed

sys admin>>
The LISTCARDScommand will simply tell the sys admin which cards are plugged into
the SCS3230 chassis. It only lists the cards (by type) as present or not present, and
does not indicate whether the cards are functioning properly.
7.9.3 VERSION Command
sys admin>>VERSION /ALL

desires to list the software version for all cards, he should type VERSION /ALLat the
command prompt. This will list the versions of the boot and flash software for all cards,
listed by card slot letter designation. Each network card will display two sets of software
versions: one set for the network portion of the card and one for the user terminal
portion, while all other cards will only return one set of version information.

sys admin>>
The INFOcommand allows the sys admin to list the properties of a card. The switch cards are
incapable of returning information, and any request to view information from the switch cards
will be refused.
The INFOcommand is used in the form INFO <slot letter>, where <slot letter>is
the letter designation of the card slot in the SCS3230 chassis. The modem card will always be
in card slot A, while the network card may be in slots B, C, D, or E.
The modem card will return the following information:
·
·

The POWERSTATUScommand displays the status of the two redundant power supplies in the
SCS3230 chassis. Power supplies will either be listed as OKor Failed. The SCS3230 will
continue to function with one failed power supply. Contact Lightwave for information regarding
replacement if a power supply fails.
7.9.6 LOGCommand
sys admin>>log /enable
The SCS3230 can report current system activity through control card port B. The report is
enable using the command LOG /ENABLE, and disabled using the command LOG /DISABLE.
The system will report user logins, logouts, device port selections, and entry/exit from direct
mode. Note that there is no system clock on the SCS3230, so there is no time/date stamp on
system activity. If a time/date stamp is required, it must be provided by the system capturing
the data output.

Connection instructions for the logging port:
1.
Turn on power to the terminal or computer. If using a computer, start the desired
communication program. The terminal or communications program used must
be in VT100 emulation mode
2.
Ensure that the communications settings are correct. The factory defaults for the
control card, which may only be changed by a hardware DIP switch, are 9600
baud, 8 data bits, 1 stop bit, and no parity (9600 8N1). If in doubt as to the
current communication settings on the control card, check the DIP switches and
refer to Figure 2, Control Card Layout with DIP Switch Settings, on page 9.
3.
Locate the serial port on the terminal or computer and determine what type of
connector is used. The cable kit included with theSCS3230 contains each of the
following: one RJ45 serial cable, an RJ45 to male DB9 adapter, an RJ45 to
female DB9 adapter, an RJ45 to male DB25 adapter, and an RJ45 to female
DB25 adapter. Select the appropriate adapter for the serial port on the terminal
or computer.
4.
5.
Firmly seat the adapter in the serial port. Screw down the adapter to secure it to
the serial port.
Insert one end of the serial cable into the adapter until a click is heard. Insert the
other end of the serial cable into port "B" of the control card, again until a click is
heard.
6.
7.
At the sys admin>>prompt, enter the command LOG /ENABLE. Log in as a
user as outlined in chapter 7. Check for output on the logging port. If no output
has appeared, check all cable connections. If “garbage” characters appear,
check that all communications parameters match.
The SCS3230 will continue to output logging information through the “B” port of the
control card until the command LOG /DISABLEis entered at the sys admin>>prompt.
Configure any text captures or scripts as needed to receive the logging data.
7.10 Sys Admin Session Management Commands
The SCS3230 features two commands that allow the sys admin to manage properties of the
control port terminal session.

Lines per page set to 10
sys admin>>
The LINESPERPAGEcommand allows the sys admin to change the number of lines displayed
per terminal page on the control card port before the MOREprompt is displayed. The number of
lines to display per page is entered after the command. Entering the command without a
number following will display the current number of lines displayed per page. The default value
is 22, which will work properly with a 24-line display.
7.10.2
TIMEOUT Command
sys admin>>TIMEOUT
Timeout set to 1 minutes
sys admin>>TIMEOUT 0
Timeout set to 0 minutes
0 disables the timeout from occurring
sys admin>>TIMEOUT 5
Timeout set to 5 minutes
sys admin>>
The TIMEOUTcommand allows the sys admin to define a time limit on how long an idle sys
admin terminal may remain logged in. If there is no interaction for the defined amount of time,
the control card will log out the sys admin. The time limit in minutes is entered as a command
qualifier after the command, and must be entered as a whole number. Defining the time limit as
0 will disable this function. The default value is one minute.
7.11 Breaking User Connections
The sys admin has four commands available to forcibly break user connections to
devices. The commands BREAKand FORCELOGOUTallow the sys admin to break any
connection on demand, while TELNETTIMEOUTand MODEMTIMEOUTautomatically
break idle user sessions for the network or modem card.

7.11.1
BREAK Command
sys admin>>BREAK 1
Break this connection? (write out YES) Yes or No: No>yes
sys admin>>
The BREAKcommand allows the sys admin to disconnect a user from the device port to
which they were connected if they are in monitor, listen, or direct mode. The user is still
logged in after the connection is broken, but there is no longer any connection between
the terminal port and the device port. The sys admin must specify the terminal port
number (as listed with the CONNECTIONScommand) ofthe connection to be severed
when using the BREAKcommand. Pressing <ENTER>or typing NOat the confirmation
prompt will abort the command. To execute the command, enter YESat the
confirmation prompt.
7.11.2
FORCELOGOUT Command
sys admin>>FORCELOGOUT 1

The FORCELOGOUTcommand causes the forcible logout of a user at any level of
connection. The user will be returned to the LCI3200>prompt after being forced off,
and may login again unless their allowed logins are reduced to 0 before they can
attempt another login. When using the FORCELOGOUTcommand, the sys admin must
specify the terminal port number (as listed with the CONNECTIONScommand) of the
user to be forced off. Pressing <ENTER>or typing NOat the confirmation prompt will
abort the command. To execute the command, enter YESat the confirmation prompt.

Timeout set to 5 minutes
Sys admin>>TELNETTIMEOUT 0
Timeout set to 0 minutes
0 disables the timeout from occurring
sys admin>>TELNETTIMEOUT 2
Timeout set to 2 minutes
sys admin>>
The TELNETTIMEOUTcommand allows the sys admin to define the amount of time that a
network card may have an idle telnet session before breaking the network connection. A telnet
session is considered to be idle if no characters are sent from the user’s terminal. Once the
time limit has been reached, the user will be logged out and the network connection will be
broken. The connection will be broken if there is no activity at any login level (from logged out
up to direct mode). This is intended to prevent a “dead” session from tying up system
resources. This command will define the idle time limit for all network cards present in the
chassis.
To display the current system value for the idle telnet session time limit, type TELNETTIMEOUT
at the command prompt. To change the time limit, the command is entered in the form
TELNETTIMEOUT<t>, where <t>is the time limit in whole minutes. The valid range for <t>is
0 to 30, with the default value set as 1. If the value is set to 0, then the time limit is disabled.
7.11.4
MODEMTIMEOUT Command
Sys admin>>modemtimeout
Timeout set to 5 minutes
Sys admin>>modemtimeout 0
Timeout set to 0 minutes
0 disables the timeout from occurring
Sys admin>>modemtimeout 2
Timeout set to 2 minutes
sys admin>>
The MODEMTIMEOUTcommand is identical to the TELNETTIMEOUTcommand, but causes the
automatic disconnection of idle modem card sessions. The modem card will deselect any
currently selected device port channel, log the user out, and disconnect the telephone
connection once the idle session time limit has been reached. Entering the time limit in whole
minutes after the command sets the idle time limit. Entering a value of 0 will disable the
timeout. Entering the command by itself will display the current modem idle call time limit.
Any users listening to a connection that is broken by BREAK, FORCELOGOUT,
TELNETTIMEOUT, or a MODEMTIMEOUTwill lose the connection as well.

SCS3230 System Administrator's Guide
8: User Access and Interface
8.1 Terminal Card
Each terminal card has four (4) RJ45 connector ports to which a terminal may be attached,
giving a maximum of 16 physically connected terminals per SCS3230 unit. The terminal card
may be installed in slots B, C, D, or E.
To access servers through the SCS3230 terminal card, the user must have at least a text
terminal capable of serial communication, a serial cable terminating in an RJ45 connector, and
the proper serial communication settings as determined by the system administrator. The
default communication settings are 38400, N, 8, or 1.
Once the hardware is properly connected and configured, the user may issue commands to the
terminal card. Before entering any commands, the user should be sure that the terminal card is
ready to accept commands by checking that there is a prompt on screen. This is best
accomplished by pressing <ENTER>until a prompt appears on the screen (a prompt will not
appear on the screen if the terminal port is in direct mode, or if the serial cable is not connected
properly).
8.2 Network Card
The network card must be connected to a network that uses TCP/IP. There is one 10/100 IP
Network port, part of the NETWORK/CONTROL card.
Network settings are entered via the Sys Admin port.
To connect to the SCS3230 network card, the user should use a TCP/IP telnet client to telnet to
the IP address assigned to the network card.

complete, the network card obtains its network parameters from the control card, and is
ready to accept connections over the network. It is important to note that the network
card does not retain its network parameters (i.e., IP address, subnet mask, gateway
address) if moved from one card slot to another. The network parameters remain
assigned to a card slot, and will be assigned to whatever network card is in that slot.
8.3 Modem Card
The modem card allows users to remotely access the servers attached to theSCS3230
via a dial-up connection. The modem automatically detects the connection speed, and
allows connections of up to 38.4K baud. The control card must complete its start-up
initialization check before a user may access the SCS3230 through the modem card.
The modem card must be installed in card slot "A" of the SCS3230 chassis. The
modem card will not function if it is inserted in any other card slot, nor will any other card
type function in slot A. To connect the modem card to the telephone network, insert an
ordinary telephone cable (RJ11) in the jack on the modem card, and insert the other
end in a telephone network jack, as outlined in section 5.3. See section 6.6 for
instructions on setting the modem initialization string.
The user interface for the modem card is identical to that found on the terminal card with
the exception of one command, which is outlined below. Only one user at a time may
connect to the modem card.
8.3.1 The ByeCommand
A user may disconnect from the modem card and automatically log out from the SCS3230 by
sending the BYEcommand. This command will work at any login level that the user may send
commands to the SCS3230 (i.e., logged out, logged in, and monitor mode). When the
command is received, the modem card disconnects the telephone connection, and then logs the
user out from the SCS3230. This command is unique to the modem card user interface.

8.4 Overview of Commands
Several levels of access are available to the user, from simple access of the SCS3230 to direct
access of servers attached to the SCS3230. Many of the commands are sensitive to which
level the user is in, and not all commands are available at all levels.
The first prompt the user should see after connecting to the SCS3230 is the LCI3200>prompt
(additional information may be on the screen as indicated in the sections above). This indicates
that the user is not currently logged in and that no servers may be reached through the
SCS3230. The prompt will change to reflect the level in which the user is, and in monitor mode,
will also indicate which server is selected.
The help screens also change according to the user's login level. There are separate
help screens for a logged out user, a logged in user, and a user in monitor (a.k.a.
device) mode.

+-----------------+
To login, the user must type LOGINat the LOGGED OUT>prompt or select USER LOG IN from
the pull-down menu. The user ID may also be entered as a command qualifier after the login
command.
LOGGED OUT>LOGIN
Please Enter User ID user_ID
Please Enter Password ****
- OR -
LOGGED OUT>login user_ID
Please Enter Password ****
If using the pull-down menu or if no user ID was entered as a qualifier, the SCS3230 will the
prompt the user for their user ID by displaying Please Enter User ID. At this prompt, they
should type the user ID assigned to them by the system administrator. After the user has
entered their ID, they will be prompted for their password when the SCS3230 displays Please
Enter Password. On the first login, this will be a password assigned by the system
administrator. The password is case sensitive, so the user must be sure to type the password
exactly as it is in the system. The SCS3230 will only echo stars for each character typed at the
password prompt. Once the user has entered their password, the screen will clear, and a
prompt displaying their user ID will appear, indicating that the SCS3230 is ready for use. For
example, a user with an ID of "GEORGE" will have a prompt of GEORGE>once they have
logged in.
When a user profile is created by the sys admin, the password is pre-expired.
The user must change the password assigned by the sys admin before selecting
a device or listening to a device port for the first time.
To change the password, the user must use the command CHANGEPSWDor PASSWD. The
SCS3230 will first prompt the user for the old password by displaying PLEASE ENTER OLD
PASSWORD. At this prompt, the user should enter the old password and press <ENTER>. The
SCS3230 will then prompt the user for the new password by displaying the prompt PLEASE
ENTER NEW PASSWORD. The user should enter the new password (which may be up to ten

entering the new password, the user will be asked to verify the new password by the prompt
PLEASE VERIFY PASSWORD. The user should enter the new password again at this prompt
exactly as it was typed the first time and press <ENTER>. If both new password entries match,
the SCS3230 will display New password accepted.on the screen and return to the user
prompt. If the new entries do not match, the message New and verify password
mismatchis displayed, the new password is rejected, and the old password remains valid.
The SCS3230 will also reject a new password if the incorrect password is entered when
prompted for the old password, or if the new password is the same as the old password.
8.6 Logging Out
A user may logout at any time that commands may be made to the SCS3230 by typing LOGOUT,
LOGOFF, or by selecting LOGOUTfrom a pull-down menu. When a user is connected to a server
and they logout, the connection to that server will be broken and any other users that are
listening to that session will lose their connection to that server as well.

Only one user at a time may connect to a device on the SCS3230, except when using listen
mode (see Section 7.9, Listening to a Server Session for more details). Before attempting to
select a device port, the user may desire to check if the device port is free. The CONNECTIONS
command allows the user to list the users that are logged in, which devices they have currently
selected, and which mode they are in. Users may also view this information by selecting

To select a device port, the user must type SELECTalong with a device port name or number,
or select CONNECT TO SERVERfrom the pull down menu, and then select the device port to be
connected. The user must also have permission to connect to a device port as defined by the
system administrator in their user profile. For example, to connect to a server named Alpha on
device port 23, the user may either type SELECT Alpha, SELECT 23, or select CONNECT TO
SERVERand then select Alphafrom the next menu that appears. If the system administrator
has determined that the user does not have permission to access a server, the SCS3230 will
display the message NO ACCESS TO DEVICE CHANNEL, and the connection will not be made.
The user may exit from their current device port first by using the EXIT command or selecting
EXIT FROM SERVERfrom the pull-down menu to free the device port for use by other users. A
user may not select a server that is already selected by another user. When a server has been
selected, the prompt will change to show which server has been selected by displaying the user
ID, a dash, and then the server name in the general form USER_NAME-SERVER_NAME>. For
example, if the user GEORGE selects Alpha, the prompt would read GEORGE-Alpha>.

When this prompt is displayed, the user is in monitor mode. There is no direct communication
between the user and the server. Any output from the server is saved to a buffer that may be
accessed by the user (see Section 7.11, Using the Buffer), but the user may issue no
commands to the server. If the user desires to issue commands to the server, they must enter
direct mode (see Section 7.10, Direct Mode).
Note that when selecting a server from a pull-down menu, only those device ports that are

To monitor another user's server session, the user must type LISTENfollowed by the device
port name or number, or select LISTEN TO SERVERand a device port from the pull-down
menu. There must be a connection between a user and a device port for another user to be
able to listen to the connection. Also, the user must have permission to listen to the server as
defined by the system administrator in their user profile. Any user that can log in and has listen
permission for a device port may listen to a session on that device port. If the user does not
have permission to listen to a server, the SCS3230 will display the message NO ACCESS TO
DEVICE CHANNEL.
When listen mode is entered, the screen will clear, and the message LISTEN MODE, PRESS
ANY KEY TO EXIT....will appear. To exit listen mode the user may press any key. The
user will also exit listen mode if the connection between the other (interactive) user and the
device port is broken.

If a user desires to interact directly with a server rather than only monitor its output, then they
must enter direct mode. To enter direct mode using the DIRECTcommand, the user must first
select a device port as outlined in Section 7.8, Selecting a Server. Then at the prompt, the user
must use the command DIRECT or select the command ENTER DIRECT MODEfrom the pull-
down menu. The user may also select a device port and enter direct mode in one step by using
the DISELECTcommand or selecting DIR CONNECT TO SERVERfrom the pull-down menu.
The DISELECTcommand must have either the device port number or the name assigned to the
port as the command qualifier; if using the pull-down menu, a prompt box will appear to select
the device port.
The user's terminal will then be directly connected to the server, and will act as if the terminal
was physically connected to the server. The SCS3230 displays the last page of the device
buffer along with a system information message indicating which device port is selected as the
user enters direct mode.
8.10.1
Direct Mode Escape Sequence
To escape from direct mode, the direct mode escape sequence must be used. The direct mode
escape sequence is a series of two to five characters that allow the user to leave direct mode
and return to monitor mode. The factory default for the direct mode escape sequence is <ESC>
A(escape key, then uppercase "a"), but the user may change the sequence by using the
command EDITESC or selecting CHANGE DIRECT MODE ESCfrom the pull-down menu at the
user prompt. It is recommended that the user only change the escape sequence if it causes
problems with the hardware or software used. It is also recommended that the user avoid
combinations of the <CTRL>key and other keys, as these combinations are usually reserved for
sending and receiving special characters through the terminal. When the user changes the
escape sequence, a window with the hexadecimal representation of the old escape sequence
will appear. Pressing <ESC>to exit from the edit prompt will not work; it will add additional

wishes to keep the old sequence, they need only to press <ENTER>. Otherwise, they should
press backspace to delete the old characters, then enter the new sequence and press
<ENTER>. If for some reason the selection is unacceptable, an error message will appear and
the sequence will revert to the old character values. The escape sequence is stored with the
user profile, therefore it is possible to have different sequences for different users. A hardcoded
escape sequence is provided in the event that the programmed sequence is lost. It is semi-
colon, exclamation, semi-colon, exclamation or ‘;!;!’none of these characters should echo
and no <ENTER> is required.

Each device port saves the output of a server to a FIFO buffer. Each buffer can store up to 64K
of data, giving approximately 100 text pages. However, the actual amount of pages may vary
according to the data. The user must be in monitor mode to view or clear the data stored in the
buffer.

The CAT and CAT WITH FILTER commands allow a user to output the content of the device
buffer to the screen. This allows a user to capture the contents of a device buffer by using the
telnet client/terminal emulation software’s texr capture capabilities.
CAT outputs the data in the buffer exactly as it was received without any additional formatting.
CAF outputs the data in the buffer by applying the same formatting that is used by the TOP,
BOTTOM, NEXT, and PREVIOUStype commands. Characters are counted and a <CR><LF>is
added after 80 characters if one is not found in the data. Due to the counting, escape
sequences may not be preserved. Tabs are considered one character.

The user may find it necessary to send a break to the selected server. The break generation
sequence is a two to five character sequence. The factory default break generation sequence is
<ESC> B(the escape key, then uppercase "b").
The user may edit the break generation sequence in a manner similar to the direct mode
escape sequence. The user may use the command EDITBRK or select CHANGE BREAK MODE
ESCfrom the pull-down menu. It is recommended that the user only change the break
generation sequence if it causes problems with the hardware or software used. It is also
recommended that the user avoid combinations of the <CTRL>key and other keys, as these
combinations are usually reserved for sending and receiving special characters through the
terminal. When the user changes the break generation sequence, a window with the
hexadecimal numerical equivalent of the old break generation sequence will appear. Pressing
<ESC>to exit from the edit prompt will not work; it will add additional <ESC>characters
(hexadecimal value 1B) to the break generation sequence. If the user wishes to keep the old
sequence, they need only to press <ENTER>. Otherwise, they should press backspace or
