Lindy Switch 32530 User Manual

The modular LINDY KVM Switch series U8/16

The U8/16 KVM switch series provides either 8 or 16 KVM server ports

supporting both PS/2 and USB keyboard and mouse connections.

This KVM switch series incorporates a modular concept design which

allows for dual console access. The local console port allows direct

access whilst a second console option permits remote access either via

remote IP or via a remote Cat.5 extender Unit. This option allows

system administrators to access and administrate their servers and

KVM switches from a remote office workstation. The required optional

IP or Cat.5 access modules can be purchased separately and are

simply installed into the back of a U8/16-Modular KVM Switch.

This manual also covers the KVM Switch U8/16-C, another version of

this modular KVM switch series that is used only in conjunction with the

modular LINDY KVM LCD Terminals U8/16-C. U8/16-C models can

only be installed in the back of an appropriate 19” LCD drawer and do

not have a display or front panel controls fitted. Any references to front

panel display and switch buttons in this manual does not apply to the

modular version U8/16-C.

Section 1

Introducing the U8/16-IP

Section 1

Introducing the U8/16-IP

The U8/16-IP provides a non-intrusive solution for remote access and control because the

software runs on its embedded processors only, so there’s no interference with computer

operation, or impact on network performance. The U8/16-IP also features remote mass storage

support; a USB connection from the switch to one of the connected computers allows virtual

storage to be set up on the host and accessed from the client.

1.1. About the U8/16 concept

The U8/16 series KVM switch supports traditional PS/2 mouse and keyboard connections as

well as modern USB connections. The U8/16 series supports the following computer platforms,

PC, Mac and SUN.

1.3. U8/16-Modular with Cat.5 Access module: U8/16-C5

Combined KVM cables are used to connect the servers to the KVM switch’s computer ports.

Connections to the servers use a traditional VGA connector, one PS/2 mouse connector and

one USB mouse & keyboard connector. To connect a server via USB only the PS/2 connector is

not used; to connect the server via PS/2 the green PS/2 mouse connector is plugged into the

servers mouse port and a special USB to PS/2 keyboard adapter is attached to the USB cable

and then plugged into the server’s PS/2 port.

If the Cat.5 KVM Extender module is installed it will allow remote access to the KVM switch

U8/16 and its connected servers via a dedicated Cat5e/6 RJ45 cable with a maximum length of

up to 100m @ 1024 x 768. The remote console consists of a Cat.5 Extender receiver unit which

is situated at the remote administrator’s desk. The remote receiver unit also includes a KVM

switch function which allows the administrator to either work on his local workstation or

alternatively switch to access the KVM switch and its connected servers.

The U8/16 series KVM switch introduces a modular concept for dual console operation. In

addition to the local console port the switch also offers a secondary remote access option either

via IP or via a remote Cat.5 extender unit. Using this method, system administrators are able to

access and administrate their servers and KVM switches from a remote office workstation.

Depending on your application the appropriate optional access modules can be purchased

separately and are simply installed into the back of the U8/16-Modular KVM Switch.

The Cat5e/6 KVM Extender provides real time access without any signal conversion and

delays, whilst the IP Access module converts the VGA and keyboard/mouse signals into a

TCP/IP data stream and sends them via the LAN/WAN connection to the remote user. The

performance of the IP access connection and response time will vary depending upon available

bandwidth and traffic throughput.

This advanced 8/16 port KVM switch allows direct control of up to 16 computers from a single

KVM (Keyboard, Video, and Mouse) console. The switch can also be daisy chained with further

KVM Switch U8/16 to control up to 128 servers/workstations from 8 daisy chained 16 port KVM

switches.

1.4. KVM compatibility and backward compatibility with

LINDY P-series KVM switches

Three methods of switching between the connected computers are available: 1. by pressing the

front panel push buttons; 2. by using keyboard hotkeys; or 3. via OSD (On Screen Display).

The U8/16 series KVM switches are compatible with almost any KVM switches using

STANDARD VGA, keyboard and mouse signals. The U8/16 is also compatible with older LINDY

P-Series KVM switches. Please note compatibility is only provided via the server ports of the

U8/16 series KVM switch but not via the daisy chain ports! Therefore when customers are

willing to mix U- and P-series KVMs (or other brand KVMs) it has to be done via port cascading

because daisy chain configuration of mixed U- and P-series KVMs cannot work. When using the

port cascading the main hotkey of the U-series KVM has to be changed (to an available hotkey

from the KVM OSD menu) so it will not conflict with the SCROLL LOCK hotkey of the P-series

KVMs or third party KVM switches.

1.2. U8/16-Modular with IP Access module: U8/16-IP

KVM over IP technology allows a simple web browser interface to be used to access the switch

and the connected computers via a local area network (LAN) or, when connected to a wide area

network (WAN), access to the switch and the connected computers can be achieved from

almost anywhere in the world.

Step 4 – Resetting the Switches

2.2. Rackmount Installation

After you have connected and switched on the SLAVE switches and computers, all of the KVM

switches may need to be reset. First, reset the SLAVE switch at the end of the daisy chain and

then reset all of the other SLAVE switches up to the MASTER U8/16 switch.

Before you start installation please verify that all

parts are included according to the package

contents.

To reset the switch, press and hold the Bank button and port 8/16 button on the front panel of

the switch.

If you want to install the KVM Switch in a 19” server

rack please attach the enclosed 19” rackmount

brackets using the screws provided.

Each SLAVE switch should now show a dash in its BANK display.

Now, reset the MASTER switch - it will show a 1 in the BANK display. Each SLAVE switch

BANK display will now change to a number according to its position in the daisy chain.

2.3. Cascading / Daisy Chaining of multiple KVM Switches

At the time this manual was written (September 2007) the U8/16 KVM switch range may be

cascaded with other LINDY U-Series KVM switches only. Later versions of the new C5-8/16

series KVM switches will be introduced that will also be daisy chainable with the U series.

All other brands and models of KVM switches may be cascaded with LINDY U-series KVM

switches via the computer ports 1-16 of the U-series KVM switch.

To connect an additional SLAVE switch to the MASTER (or previous) switch, you must use the

included special KVM system daisy chain cable. Standard VGA cables may not work correctly

as not all cables support all pins connected.

Step 1 - Connect the local console

Connect your keyboard, mouse and monitor to the console ports of the U8/16 MASTER KVM

Switch.

Step 2 – Connect the first Slave

Use the daisy chain cable to connect the daisy chain port of the MASTER/previous KVM

Switch and the other end to the local console port of the next SLAVE switch.

Step 3 – Cascading / Daisy chaining

Repeat the previous step to daisy chain mores switches. Each individual switch in the chain

represents a different Bank. The MASTER switch is Bank 1 and each cascaded SLAVE follows

on as Bank 2, 3, 4 etc. You may cascade a maximum of eight switches/banks.

KVM Switch Operation

3.1. KVM Switch Operation

Important note: Your monitor will only display one PC signal at any one time. All

keyboard and mouse commands are sent to this PC only. After initial power up, port 1 is

active by default.

When a PC is connected to the currently selected port and it is not switched on,

or is in sleep mode, the monitor will not display any signal.

Section 3

3.1.1. Password Security

When you power on the U8/16 it will ask you for a user name and a password. The default

user name and default password for both is eight zeros –“00000000”. Please key in eight

zeros in the password field. You may use the “0” from the standard keypad but not from the

numeric keypad.

Note: Please don’t change the password until you are familiar with the operation of the OSD

menu – i.e. keep the default password “00000000”. Otherwise, if you forget the password, you

will need to send the switch back to LINDY for maintenance to clear the password.

KVM Switch

Operation

The U8/16 OSD security feature offers up to 8 users + 1 SUPERVISOR.

A user specific access control list is available from the OSD of the KVM switch and can be

configured by the supervisor.

3.1.2. Hot Plug Support

The U8/16 supports a “Hot Plug” function for easy addition or removal of computers. The user

can arrange or maintain the computers and daisy chained KVM Switches as follows:

a. A computer can be disconnected and reconnected to the same or a different port of the KVM

switch without having to power it off as long as it is currently not connected to the console. In

most cases the PS/2 mouse and keyboard signals will be maintained and will not be lost.

b. The mouse driver of the computer has to support the hot plug function or the computer may

need to be rebooted when it is reconnected.

c. You can unplug your mouse or keyboard from the console port and plug it back in at any

time. You should not use different types of mice when performing this.

d. A SLAVE KVM switch can be added or removed at any time, but after adding or removing a

switch it may be required to reset all of the KVM switches. But you DO NOT need to reboot

the computers.

Please note: Some Operating Systems such as certain Unix versions are unable to

support the “Hot Plug” function. If you Hot Plug when using this kind of O.S., it may cause

unpredictable operation or may shut down the computer. Before attempting to use the Hot

Plug feature, please check that the O.S. and mouse driver support this function.

4.1. Cat.5 KVM Extender Features

4.3. Cat.5 KVM Extender Operation

The modular KVM switch U8/16 offers the option to use it with or without a remote console

access module. This module may either be a Cat.5 Extender or IP Access solution.

The Cat.5 Extender solution provides real time KVM access via a dedicated Cat5e/6 cable with

a maximum length of 300m. When using higher resolutions we suggest the following maximum

pixel resolution versus length: 1600x1200@75m/ 1280x1024@150m/1024x768@250m

The Cat.5 Extender Receiver unit incorporates its own OSD menu which allows switching

between the local workstation and remote KVM Switch as well as configuration of the unit.

To invoke the hotkey and OSD operation of the Cat.5 Receiver unit simply press the hotkey

(factory default setting is Caps Lock) twice and press any other command from the list below

within 2 seconds:

Overall picture quality when using the Cat.5 extender will depend on the Cat.5/5e/6 cable

quality and also on the signal quality generated by the graphics card used. To optimize the

picture quality high quality amplifiers, equalizers and an auto skew compensation circuits are

used in the Cat.5 Receiver unit to compensate for the attenuation and for the different lengths of

the individual twisted pairs inside long Cat.5/5e/6 cables.

Press any key to stop scanning

In comparison to the IP Access Extender solution the Cat.5 Extender provides a real time

analog KVM signal. And the Cat.5 KVM Extender does not require any software for operation as

it just operates as an analog KVM signal extender.

Auto adjusts the amplifiers and equalizers of the remote Cat.5 Extender

receiver unit. This auto adjustment is also performed automatically each

time the receiver unit is powered on

The Cat.5 KVM Extender module consists of two units: The local Cat.5 Extender Transmitter

module fitted into the KVM Switch slot and the remote Cat.5 Extender Receiver unit installed at

the remote user’s location.

To change the default hotkey simply activate the local OSD F2 menu. Choose a new hotkey by

typing in the appropriate number key as listed in the local OSD F2 menu.

The remote Cat.5 Extender Receiver unit includes a local KVM switch which allows the remote

user to also connect a local workstation to the receiver unit and switch between the local

workstation and remote KVM Switch access.

The following hotkeys are available: Scroll Lock / Caps Lock / Left Ctrl / Right Ctrl / Left Alt /

Right Alt / Left Win / Right Win. When choosing a new hotkey try to avoid using a hotkey

already used by any connected KVM switches as conflicts may arise when switching ports.

4.2. Cat.5 KVM Extender Installation

Before you install the local Cat.5 Extender Transmitter module into the KVM switch ensure all

connected computers are switched off and the power supply is unplugged. Proceed to unscrew

and remove the small metal cover on rear of the KVM switch. Carefully slide the module into the

slot and secure in place with the screw previously removed.

Now install the remote Cat.5 Extender Receiver unit at the remote user’s location. You will need

a VGA monitor and a USB mouse and keyboard to connect to the receiver unit. Connect your

local workstation to the receiver unit if required using the dedicated KVM system cable included

with the Cat.5 KVM Extender. Finally connect the Cat.5/5e/6 cable and the power supply unit.

The KVM cable provided can be used to connect either PS/2 or USB equipped computers in the

same way as previously described for connecting computers to the KVM switch in section 1.6.

A dedicated Cat5/5e/6 cable with RJ-45 connectors is required to connect the Receiver unit and

the Extender module located in the KVM switch. This connection must not be made via a “Live”

Ethernet connection but only via multiple cable segments using patch cables, patch panels and

wall sockets. Please consider the maximum resolution versus length limitations as mentioned

previously. Please also try to limit the number of connections between the transmitter and

receiver unit as this will help to reduce any signal loss introduced.

You may now proceed to power up all connected equipment and check for correct operation.

IP Access Configuration & Operation

5.0.1. KVM over IP Access Features

The IP access module provides remote KVM over IP access to the KVM switch U8/16. It

converts all keyboard video and mouse signals and sends them as TCP/IP signals over your

LAN/WAN connection. The KVM switch U8/16 may be accessed from any computer connected

to your network and provides full KVM access including BIOS level access to all the connected

computers.

Please note that KVM over IP does not operate in a “real time” environment and that some

degree of time delay will occur due to limiting factors such as available bandwidth and network

traffic.

Section 5

The KVM over IP Access module can be accessed via a simple web browser and via dedicated

software tools included with the product. It uses secure encrypted sessions and password

authentication protocols.

Please note that the conversion of video, mouse and keyboard signals requires a certain

amount of CPU processing time. Transporting large amounts of data over TCP/IP requires a

high bandwidth connection. Limited bandwidth may restrict or limit the possible screen

resolutions and colour depths which can be transmitted over your LAN / WAN.

IP Access

Configuration

& Operation

A connection which exhibits limited bandwidth will result in slower mouse reaction and cursor

control. Also the available screen resolution, colour depth and refresh rates will also be affected.

Ensure the connection you are using provides adequate bandwidth, some adjustment of screen

resolution, colour depth and mouse cursor control may have to be made for satisfactory

operation.

5.0.2 KVM over IP Access Module Installation

Before you install the IP Access module into the KVM switch ensure all connected computers

are switched off and the power supply is unplugged. Proceed to unscrew and remove the small

metal cover on rear of the KVM switch. Carefully slide the module into the slot and secure in

place with the screw previously removed.

You may now proceed to power up all connected equipment and check for correct operation.

For the remainder of this manual the U8/16 KVM switch with installed KVM

over IP Module will be referred to as U8/16-IP.

The U8/16-IP’s communication interfaces

are all based on TCP/IP. The switch comes

pre-configured with the following IP

configuration shown here:

MAC Address Detection

Parameter

IP auto configuration

IP-Address

Net-mask

Default-Gateway

Value

DHCP

Connect the U8/16-IP to your computer either via a local network, or via USB. If you use a USB

connection Windows will detect the U8/16-IP as a ‘Removable Disk’ and an appropriate drive

letter will be assigned.

255.255.255.0

none

Start the setup tool from the CD ROM.

Note: If the DHCP connection fails on boot-up, the U8/16-IP will not be assigned an IP

address.

A window opens as shown below:

If this initial configuration does not meet your requirements, the following section describes the

configuration that is necessary to access the U8/16-IP for the first time.

Initial Configuration via a DHCP Server

By default, the U8/16-IP will try to contact a DHCP server in the subnet to which it is physically

connected. If a DHCP server is found, it will provide a valid IP address, gateway address and

subnet mask. If a DHCP server is not available then you will need to assign a fixed IP

assignment to the MAC address of the IP Access Module. You can find the MAC address

details on the printed label on the underside of the IP Access module.

Before you connect the device to your local subnet, be sure to complete the corresponding

configuration using the setup tool supplied on the CD ROM. Follow the procedure described on

the next page (Section 5.2)

Initial Configuration via a Serial Console

The U8/16-IP has a serial line interface (host side)

for connecting a serial terminal. This connector is

compliant with the RS-232 serial line standard. The

serial line has to be configured with the parameters

given in this table:

Parameter

Bits/second

Data bits

Parity

Stop bits

Value

115200

Flow Control

None

On the upper left corner, the MAC address of the U8/16-IP is displayed. To re-detect the MAC

address, press the Refresh Devices button. The displayed MAC address should correspond to

the printed address shown on the label on the base of the IP module.

When configuring with a serial terminal, reset the U8/16-IP and immediately press the ESC key.

You will see some device information and a “=>” prompt. Type config and press the Enter key.

Wait a few seconds for the configuration information to appear.

On the lower right corner of the window, there are two buttons: Query Device and Setup

Device. Press the Query Device button to display the preconfigured values of the network

configuration. The values are displayed in the text fields located above. If necessary, adjust the

network settings to your needs. To save the changes enter a user login and a password (see

Authentication, below) and then press the Setup Device button.

As you proceed, the following questions will appear on the screen. To accept the default values

(shown in square brackets below) press the Enter key.

5.3. Keyboard, Mouse and Video Configuration

To adjust the authentication settings, enter your login as a super user and change your

password.

Between the U8/16-IP and the host, there are two interfaces available for transmitting keyboard

and mouse data: USB and PS/2. The correct operation of the remote mouse depends on

several settings which will be discussed in the following subsections. Please see page 34 for

details of how to make the specific changes to the mouse settings described below.

Super user login

Enter the login name of the super user. The initial value is "super". All of the characters are

lower case.

U8/16-IP Keyboard Settings

Super user password

Enter the current password for the super user. This initial value is "pass". All of the characters

The U8/16-IP settings for the host's keyboard type have to be correct in order to make the

remote keyboard work properly. The settings can be checked using the U8/16-IP front-end,

please see page 37 for details of how to make changes to the keyboard settings.

are lower case.

New super user password

Enter the new password for the super user.

Remote Mouse Settings

New password (confirm)

A common problem with KVM devices is the synchronization between the local and remote

mouse cursors. The U8/16-IP addresses this problem with an intelligent synchronization

algorithm. There are two mouse modes available on the U8/16-IP: Auto mouse speed and

Fixed mouse speed.

Re-type the new password for the super user.

To close the window and accept the changes, press the OK button, otherwise press the Cancel

button.

Auto mouse speed

IP Auto Configuration

The automatic mouse speed mode tries to detect the speed and acceleration settings of the

host system automatically. Speed detection is performed during mouse synchronization. If the

mouse does not move correctly, there are two ways to re-synchronize the local and remote

mouse:

With this option, you can specify whether the U8/16-IP should obtain its network settings from a

DHCP or BOOTP server. From the drop down list select either DHCP or BOOTP. If you select

NONE, the IP auto configuration is disabled and you should manually input the following

network settings:

Fast Sync: Fast synchronization is used to correct a temporary, but fixed skew. Choose this

option using the Remote Console options menu or by pressing the mouse synchronization

hotkey sequence - [ALT] + [F12]

IP address

The IP address the U8/16-IP uses.

Intelligent Sync: If the fast sync does not work correctly or the mouse settings have been

changed on the host system, you can use the intelligent resynchronization option. This method

can be accessed from the Mouse Handling sub menu of the Remote Console Option menu.

Net mask

The net mask of the connected IP subnet.

Gateway address

Intelligent synchronization requires a correctly adjusted picture. Use the auto adjustment

function or manual correction in the Video Settings panel to setup the picture. The Sync mouse

button on top of the Remote Console can behave differently, depending on the current

state of mouse synchronization. Usually pressing this button leads to a fast sync, except in

situations where the KVM port or the video mode was recently changed.

The IP address of the default router for the connected IP subnet. If you do not have a default

router, enter 0.0.0.0.

Tip: When first started, if the local mouse pointer is not synchronized with the remote mouse

pointer, click the Auto Adjust Button once. If the mouse is still not synchronized select

Intelligent Sync from the Mouse Handling sub menu of the Remote Console Option menu.

Fixed mouse speed

This mode just translates the mouse movements from the Remote Console in a way that one

pixel move will lead to ‘n’ pixel moves on the remote system. This parameter ‘n’ is adjustable.

However, it should be noted that this works only when mouse acceleration is turned off on the

remote system.

IP Access Configuration & Operation

Section 5

IP Access Configuration & Operation

Host System Mouse Settings

Recommended Mouse Settings

The host's operating system obtains various settings from the mouse driver.

For the different operating systems we can give the following advice...

MS Windows 2000/2003 (Professional and Server), XP

Note: The following limitations do not apply when using USB mice and

Windows 2000 and higher!

In general, we recommend the use of a USB mouse. Choose USB without Mouse Sync. For a

PS/2 mouse choose Auto Mouse Speed. For XP disable the option called enhance pointer

precision in the Control Panel.

Special Mouse Driver

There are mouse drivers which influence the synchronization process and lead to

desynchronized mouse pointers. If this happens, make sure you do not use a special vendor-

specific mouse driver on your host system.

SUN Solaris

Adjust the mouse settings either via xset m 1 or use the CDE Control Panel to set the mouse to

1:1, no acceleration. As an alternative you may also use the Single Mouse Mode.

Windows XP Mouse Settings

If using Windows XP, disable the enhance pointer precision setting.

MAC OS X

We recommend using the Single Mouse Mode.

Active Desktop

Video Modes

If the Active Desktop feature of Microsoft Windows is enabled, do not use a plain background.

Instead, use some kind of wallpaper. Alternatively, you could also disable the Active Desktop

completely.

The U8/16-IP switch recognizes a limited number of common video modes. When running X11

on the host system, please do not use any custom mode lines with special video modes. If you

do, the U8/16-IP switch may not be able to detect them. We recommend using any of the

standard VESA video modes instead.

Navigate your mouse pointer into the upper left corner of the applet screen and move it back

and forth slightly. In this way the mouse will be resynchronized. If re-synchronizing fails, disable

mouse acceleration and repeat the procedure.

Single and Double Mouse Mode

The information above applies to Double Mouse Mode, where both remote and local mouse

pointers are visible and need to be synchronized. The U8/16-IP also features another mode -

Single Mouse Mode, where only the remote mouse pointer is visible. Activate this mode in the

open Remote Console and click into the window area. The local mouse pointer will be hidden

and the remote one can be controlled directly. To leave this mode, use the hotkey combination

[ALT] + [F12] to free the captured local mouse pointer.

IP Access Configuration & Operation

5.4. Usage

5.5. Logging In

Prerequisites

Launch your web browser. Direct it to the address of your U8/16-IP which you configured during

the installation process. The address used might be a plain IP address or a host and domain

name if you have given your U8/16-IP switch a symbolic name in the DNS.

The U8/16-IP features an embedded operating system offering a variety of standardized

interfaces. This section will describe these interfaces, and the way to use them in a more

detailed manner. The interfaces are accessed using the TCP/IP protocol family.

Example: Type the following in the address line of your browser when establishing an

unsecured connection:

The following interfaces are supported:

Telnet

http://<IP address of U8/16-IP>

A standard Telnet client can be used to access an arbitrary device connected to the U8/16-IP’s

serial port via a terminal.

When using a secure connection, type in:

https://<IP address of U8/16-IP>

HTTP/HTTPS

Full access is provided by the embedded web server. The U8/16-IP switch environment can be

entirely managed using a standard web browser. You can access the U8/16-IP using the

insecure HTTP protocol, or using the encrypted HTTPS protocol. Whenever possible, use

HTTPS.

This will lead you to the U8/16-IP login page as shown below:

The primary interface of the U8/16-IP is the HTTP interface. This is covered extensively in this

section. Other interfaces are addressed in the relevant subsections.

In order to use the Remote Console window of your managed host system, the browser must

feature Java Runtime Environment version 1.1 or higher support. If the browser has no Java

support (such as on a small handheld device), you can still maintain your remote host system

using the administration forms displayed by the browser itself.

Important: We recommend you install the latest version of Sun’s

Java Virtual Machine which can be downloaded from the

following web site:

www.java.com

The U8/16-IP has a built-in super user account that has all the permissions enabled to

administrate your U8/16-IP switch:

For a non-secure connection to the U8/16-IP, we recommend the following browsers:

Password

pass (factory default)

Microsoft Internet Explorer version 6.0 or higher

Netscape Navigator 7.0 or Mozilla 1.6

Please note: Your web browser has to accept cookies, or else login is not possible.

Note: The user “super” is not allowed to login via the serial interface of the IP-KVM switch.

In order to access the remote host system using a securely encrypted connection, you need a

browser that supports the HTTPS protocol. Strong security is only assured by using a key

length of 128 Bit. Some older browsers do not have a strong 128 Bit encryption algorithm.

Please make sure you change the super user password immediately after you have installed

and accessed your U8/16-IP for the first time. Not changing the password for the super user is a

severe security risk and could result in unauthorized access to the switch and to the host

system(s) to which it is connected.

Section 5

IP Access Configuration & Operation

The Remote Console is the redirected screen, keyboard and mouse of the remote host system

that the U8/16-IP switch controls. Selecting this button opens the Remote Console Main

Window.

5.6. Navigation

Once logged into the U8/16-IP successfully, the main page appears. This page consists of three

parts; each of them contains specific information. The buttons in the upper area allow you to

navigate within the front end. The lower left area contains a navigation bar and allows you to

switch between the different sections of the U8/16-IP. Within the main area, task-specific

information is displayed.

The Remote Console window is a Java Applet that establishes its own TCP connection to the

U8/16-IP. The protocol that runs over this connection is neither HTTP nor HTTPS, but RFB

(Remote Frame Buffer Protocol). RFB needs to establish a connection to port number 443. Your

local network environment has to allow this connection to be made, i.e. your firewall and, if you

have a private internal network, your NAT (Network Address Translation) settings have to be

configured accordingly.

If the U8/16-IP is connected to your local network environment and your connection to the

Internet is available using a proxy server only, without NAT being configured, the Remote

Console is very unlikely to be able to establish a connection. This is because today's web

proxies are not capable of relaying the RFB protocol.

If you experience problems, please consult your network administrator in order to provide an

appropriate network environment.

This link logs out the current user and presents a new login screen. Please note that an

automatic logout will be performed if there is no activity for half an hour. Clicking one of the links

will bring you back to the login screen.

Starting the Remote Console opens an additional window. It displays the screen content of the

currently selected computer connected to the U8/16-IP. The Remote Console will behave in

exactly the same way as if you were using the local console. You can use the U8/16-IP

keyboard hotkeys to switch between computers, activate the OSD etc., as well as control the

currently selected computer. However, be aware that the host system will react to keyboard and

mouse actions with a slight delay.

IP Access Configuration & Operation

Note: Your local keyboard changes its keyboard layout according to the remote host system. If

you use a German administration system and your host system uses a US English keyboard

layout for instance, some special keys on the German keyboard will not work as expected.

Instead, the keys will result in their US English counterpart. You can circumvent such problems

by adjusting the keyboard of your remote system to the same mapping as your local one.

Options

Opens the Options menu. A short description of the each of the options follows:

Monitor Only

Toggles the ‘Monitor only’ filter on or off. If the filter is switched on, no remote console

interaction is possible but monitoring is.

The Remote Console window always tries to show the remote screen with its optimal size. That

means it will adapt its size to the size of the remote screen initially and after the screen

resolution of the remote screen has been changed. However, you can always resize the

Remote Console window in your local window system as usual.

Exclusive Access

If a user has the appropriate permission, he can force the Remote Consoles of all other users to

close. No one can open the Remote Console at the same time again until this user disables the

exclusive access, or logs off.

Remote Console Control Bar

The upper part of the Remote Console window contains a control bar. Using its elements you

can see the state of the Remote Console and influence the local Remote Console settings. A

description for each control follows.

A change in the access mode is also visible in the status line indicated by this icon.

Scaling

Allows you to scale down the Remote Console. You can still use both mouse and keyboard;

however the scaling algorithm will not preserve all display details.

Mouse Handling

The submenu for mouse handling offers two options for synchronizing the local and the remote

mouse pointer.

Ctrl+Alt+Delete

Sends the ‘Control Alt Delete’ key combination to the remote system

Fast Sync

The fast synchronization is used to correct a temporary, but fixed skew.

Auto Adjust button

If the video display is poor quality or distorted in some way, click this button and wait a few

seconds while the U8/16-IP tries to adjust itself for the best possible video quality.

Intelligent Sync

Use this option if the fast sync does not work or the mouse settings have

been changed on the host system

Sync mouse

Note: This method takes more time than fast sync and requires a correctly

adjusted picture. Use the auto adjustment function or the manual correction in

the Video Settings panel to setup the picture.

Activates the mouse synchronization process. Choose this option in order to synchronize the

local AND remote mouse cursors. This is especially necessary when using accelerated mouse

settings on the host system. In general, there is no need to change mouse settings on the host.

Local Cursor

Offers a list of different cursor shapes to choose from for the local mouse pointer. The selected

shape will be saved for the current user and activated the next time this user opens the Remote

Console. The number of available shapes depends on the Java Virtual Machine; a version of

1.2 or higher offers the full list.

Single/Double mouse mode

Switches between the Single Mouse Mode (where only the remote mouse pointer is visible) and

the Double Mouse Mode (where remote and local mouse pointers are visible) Single mouse

mode is only available if using SUN JVM 1.3 or higher.

Video Settings

Opens a panel for changing the U8/16-IP video settings. The U8/16-IP features two different

dialogs, which influence the video settings:

Tip: When in single mouse mode use the hotkey combination [ALT] + [F12] to release

mouse control and access the menus etc.

Video Settings in the KVM section in the front end menu:

The Noise Filter option defines how the U8/16-IP reacts to small changes in the video input

signal. A large filter setting needs less network traffic and leads to a faster video display, but

small changes in some display regions may not be recognized immediately. A small filter

displays all changes instantly but may lead to a constant amount of network traffic even if

display content is not really changing (depending on the quality of the video input signal). All in

all the default setting should be suitable for most situations.

The U8/16-IP firmware features a Telnet server that enables a user to connect via a standard

Telnet client. If the Telnet program is using a VT 100, VT 102 or VT 220 terminal or appropriate

emulation, it is even possible to perform a console redirection, as long as the U8/16-IP host is

using a text mode screen resolution.

Connecting to the U8/16-IP is done as usual and as required by the Telnet client, for instance in

a UNIX shell:

telnet 192.168.1.22

Replace the IP address by the one that is actually assigned to the U8/16-IP. This will prompt for

the username and password in order to log into the device. The credentials that need to be

entered for authentication are identical to those of the web interface. That means the user

management of the Telnet interface is entirely controlled with the appropriate functions of the

web interface.

Once you have successfully logged into the U8/16-IP a command line will be presented and you

can enter management commands.

In general, the Telnet interface supports two operation modes: the command line mode and the

terminal mode. The command line mode is used to control or display some parameters. In

terminal mode the pass-through access to serial port 1 is activated (if the serial settings were

made accordingly). All inputs are redirected to the device on serial port 1 and its answers are

displayed on the Telnet interface.

5.7.2. Virtual Media

Windows users should use the tool, RawWrite for

Windows, which is included on the supplied CD.

One of the computers connected to the U8/16-IP can also be set up for remote mass storage

via a USB connection. Files can be uploaded to the switch, which the host computer ‘sees’ as

virtual drives. This means the remote operator can remotely install software, drivers etc. without

the need to be sat in front of the host computer.

Launch RawWrite, you will see the window

opposite:

Insert your floppy disk into your floppy drive. Click

the Read tab and then click on

Floppy Disk

Select a name and destination for the floppy image

file and click the Read button. As the image is

figure in the bottom left hand corner.

When the image has been written you can upload it

to the U8/16-IP.

Uploading a Floppy Image

Click the Browse button and navigate to

the location of the image file, then click

the Upload button.

After the image has uploaded you will see the dialog below:

Follow the steps below to upload a virtual floppy image to the U8/16-IP and create a virtual

floppy drive on the host system.

Create a Floppy Image

First, on your client PC you must create an image of your floppy disk which can be uploaded to

the U8/16-IP’s built in memory.

UNIX and UNIX-like OS

To create an image file, make use of dd. This is one of the original UNIX utilities and is included

in every UNIX-like OS (UNIX, Sun Solaris, and Linux).

A virtual floppy drive will be installed on the host system and the image will be downloaded to

the virtual floppy drive from the U8/16-IP. You can access the virtual floppy drive in the same

way you would a regular drive.

To create a floppy image file copy the contents of a floppy to a file. You can use the following

command:

You can download the image from the U8/16-IP to your remote system by clicking the

Download button.

dd [ if=/dev/fd0 ] [ of=/tmp/floppy.image ]

Clicking Discard removes the virtual floppy image from the U8/16-IP and from the hosts

system.

dd reads the entire disc from the device /dev/fd0 and saves the output in the specified output

file /tmp/floppy.image. Adjust both parameters exactly to your needs (input device etc.)

Follow the procedure below to create a CD-ROM image which can be accessed by the host

system via the U8/16-IP. The image file must be an ISO file format!

First, on your client PC you must create an image of your CD which can be accessed by the

host system.

4. Next you need to mount the image via a

Windows Share. In the U8/16-IP menu on the

left hand side of the browser select Virtual

Media and from the sub menu select CD-

ROM Image.

UNIX and UNIX-like OS

To create an image file, make use of dd. This is one of the original UNIX utilities and is included

in every UNIX-like OS (UNIX, Sun Solaris, and Linux).

To create a CD-ROM image file, copy the contents of the CD-ROM to a file. You can use the

following command:

The Drive Redirection feature allows the host system to access the CD-Rom drives, hard drives,

floppy drives etc. on your client PC.

To use this feature you need the Drive Redirection Tool which is part of the KVM Vision Viewer

application included on the supplied CD.

SAMBA

If you would like to access the share via SAMBA, SAMBA must be set up properly. You may

either edit the SAMBA configuration file /etc/samba/smb.conf, or use the Samba Web

Administration Tool (SWAT) or WebMin to set the correct parameters.

5.7.3. User Management

Users And Groups

The U8/16-IP comes with 2 pre-configured user accounts that have fixed permissions. The

super account has all possible rights to configure the device and to use all functions. The user

account has only the permission to open and use the Remote Console. The default password

for both accounts is "pass". Ensure you change the passwords as soon as you have installed

and accessed the U8/16-IP for the first time.

Change Password

To change your password, enter the new password in the upper entry field. Retype the

password in the lower field. Click Apply to submit your changes.

While the user account never sees the following options, the super account can change the

name and password for both accounts.

Existing users

5.7.4. KVM Settings

Allows adjustment of both compression rate and colour depth individually. Depending on the

selected compression rate the data stream between the U8/16-IP and the Remote Console will

be compressed in order to save bandwidth. Since high compression rates are very time

consuming, they should not be used when several users are accessing the U8/16-IP

simultaneously.

User Console

The following settings are user specific. This means the super user can customize these

settings for individual users separately. Changing the settings for one user does not affect the

settings for the other users.

The standard colour depth is 16 bit (65536 colours). The other colour depths are intended for

slower network connections in order to allow a faster transmission of data. Therefore

compression level 0 (no compression) uses only 16 bit colour depth. At lower bandwidths only 4

bit (16 colours) and 2 bit (4 grey scales) are recommended for typical desktop interfaces. Photo-

like pictures have best results with 4 bit (16 grey scales). 1 Bit colour depth (black/white) should

only be used for extremely slow network connections.

Remote Console Type

Specifies, which Remote Console Viewer to use.

Default Java-VM

Uses the default Java Virtual Machine of your Browser. This may be the Microsoft JVM for

Internet Explorer or the Sun JVM if it is configured this way. Use of the Sun JVM may also be

forced (see below).

User select Unit

This box displays the user ID for which the values are shown and for which the changes will

take effect. You may change the settings of other users if you have the necessary access rights.

Transmission Encoding

The Transmission Encoding setting allows changing the image-encoding algorithm that is used

to transmit the video data to the Remote Console window. It is possible to optimize the speed of

the remote screen depending on the number of users working at the same time and the

bandwidth of the connection line (Modem, ISDN, DSL, LAN, etc.).

Automatic detection

The encoding and the compression level are determined automatically from the available

bandwidth and the current content of the video image.

Pre-configured

The pre-configured settings deliver the best result because of optimized adjustment of

compression and colour depth for the indicated network speed.

Sun Microsystems Java Browser Plug-in

Instructs the web browser of your administration system to use Sun’s JVM. The JVM in the

browser is used to run the code for the Remote Console window which is actually a Java

Applet. If you check this box for the first time on your administration system and the appropriate

Java plug-in is not already installed on your system, it will be downloaded and installed

automatically. However, in order to make the installation possible, you still need to answer the

appropriate dialogs with yes. The download size is around 11MB. The advantage of

downloading Sun's JVM is in providing a stable and identical Java Virtual Machine across

different platforms. The Remote Console software is optimized for Sun JVM versions and offers

wider range of functionality when run with JVM.

Miscellaneous Remote Console Settings

Start in Monitor Mode Sets the initial value for the monitor mode. By default the

monitor mode is off. In case you switch it on, the Remote Console window will be

started in a read only mode.

Start in Exclusive Access Mode Enables the exclusive access mode

immediately at Remote Console startup. This forces the Remote Consoles of all

other users to close. No one can open the Remote Console at the same time

again until this user disables the exclusive access or logs off.

Mouse hotkey

Allows the user to specify a hotkey combination which starts either the mouse synchronization

process if pressed in the Remote Console or is used to leave the single mouse mode.

Remote Console Button Keys

This allows simulating keystrokes on the remote system that cannot be generated locally. The

reason for this might be a missing key or the fact that the local operating system of the Remote

Console is unconditionally catching this keystroke already. Typical examples are

Control+Alt+Delete in Windows and DOS, which is always caught, or Control+Backspace on

Linux for terminating the X-Server. The syntax to define a new Button Key is as follows:

Host Interface

Enables the interface the mouse is connected to. You can choose between Auto for automatic

detection, USB for a USB mouse, or PS/2 for a PS/2 mouse.

Note: To use the USB and/or PS/2 interface you need the correct cabling between the

managed host and the managing device. If the managed host has no USB keyboard support

in the BIOS and you have connected the USB cable only, then you will have no remote

keyboard access during the boot process of the host. If USB and PS/2 are both connected

and you selected Auto as host interface, then USB will be selected if available, otherwise it

will revert to PS/2.

[confirm] <keycode>[+|-[*]<keycode>]*

confirm requests confirmation by a dialog box before the key strokes will be sent to the remote

host.

keycode is the key to be sent. Multiple key codes can be joined with a plus, or a minus sign.

The plus sign builds key combinations; all keys will be pressed until a minus sign or the end of

the combination is encountered. In this case all pressed keys will be released in reversed

sequence. So the minus sign builds single, separate key presses and releases. The star inserts

a pause with duration of 100 milliseconds.

To enable USB remote keyboard access during the boot process of the host, the following

conditions must be fulfilled:

the host BIOS must have USB keyboard support

the USB cable must be connected or must be selected in the Host interface option

PS/2 Keyboard Model

Enables a certain keyboard layout. You can choose between Generic 101-Key PC for a

standard keyboard layout, Generic 104-Key PC for a standard keyboard layout extended by

three additional windows keys, Generic 106-Key PC for a Japanese keyboard, and Apple

Macintosh for the Apple Macintosh.

Enables USB mouse type. Choose between MS Windows 2000 or newer for MS Windows

2000 or Windows XP, or Other Operating Systems for MS Windows NT, Linux, or OS X. In MS

Windows 2000 or newer mode the remote mouse is always synchronized with the local

mouse.

To support signal transmission from a Sun machine, enable this option. If not enabled the

picture of the remote console will not be visible. To set the options, click Apply.

Mouse Speed

Auto mouse speed Use this option if the mouse settings on the host use an additional

acceleration setting. The U8/16-IP tries to detect the acceleration and speed of the mouse

during the mouse sync process.

Fixed mouse speed Use a direct translation of mouse movements between the local and

the remote pointer.

5.7.5. Device Settings

Network

The Network Settings panel allows network related parameters to be changed. Each parameter

will be explained below. Once applied the new network settings will immediately come into

effect.

You may also set a fixed scaling which determines the amount the remote mouse pointer is

moved when the local mouse pointer is moved by one pixel. This option only works when the

mouse settings on the host are linear. This means that there is no mouse acceleration involved.

To set the options, click on the Apply button.

Video

Note: The initial IP configuration is usually done directly at the host system using the

special procedure described on Page 20.

Changing the network settings of the U8/16-IP might result in losing connection to it. In case

you change the settings remotely make sure that all the values are correct and you still have

an option to access the U8/16-IP.

Miscellaneous Video Settings

Noise filter

This option defines how the U8/16-IP reacts to small changes in the video input signal. A large

filter setting needs less network traffic and leads to a faster video display, but small changes in

some display regions may not be recognized immediately. A small filter displays all changes

instantly but may lead to a constant amount of network traffic even if the display content is not

Dynamic DNS

IP auto configuration

With this option you can control if the U8/16-IP should obtain its network settings from a DHCP

or BOOTP server. For DHCP, select dhcp, and for BOOTP select bootp. If you choose none

then IP auto configuration is disabled.

A freely available Dynamic DNS service (dyndns.org) can be used in the following scenario (see

illustration below)

IP address

IP address in the usual dot notation.

Subnet Mask

The net mask of the local network.

Gateway IP address

In case the U8/16-IP is accessible from networks other than the local one, this IP address must

be set to the local network router's IP address.

Primary DNS Server IP Address

IP address of the primary Domain Name Server in dot notation. This option may be left empty;

however, the U8/16-IP will not be able to perform name resolution.

Secondary DNS Server IP Address

IP address of the secondary Domain Name Server in dot notation. It will be used in case the

Primary DNS Server cannot be contacted.

Remote Console and HTTPS port

Port number at which the U8/16-IP’s Remote Console server and HTTPS server are listening. If

left empty the default value will be used.

HTTP port

Port number at which the U8/16-IP’s HTTP server is listening. If left empty the default value will

be used.

The U8/16-IP is reachable via the IP address of the DSL router, which is dynamically assigned

by the provider. Since the administrator does not know the IP address assigned by the provider,

the U8/16-IP connects to a special dynamic DNS server in regular intervals and registers its IP

address there. The administrator may contact this server as well and pick up the same IP

address belonging to his device.

Telnet port

Port number at which the U8/16-IP’s Telnet server is listening. If left empty the default value will

be used.

The administrator has to register a U8/16-IP that is supposed to take part in the service with the

Dynamic DNS Server and assign a certain hostname to it. He will get a nickname and a

password in return. This account information, together with the hostname, is needed in order to

determine the IP address of the registered U8/16-IP.

Bandwidth limitation

The maximum network traffic generated through the U8/16-IP’s Ethernet device. Value in Kbit/s.

Enable Telnet access

Set this option to allow access to ARA express using the Telnet Gateway (see the Section

called Telnet Console on page 36.)

You have to perform the following steps in order to enable Dynamic DNS:

Make sure that the LAN interface of the U8/16-IP is properly configured.

Open the Dynamic DNS Settings configuration dialog

Enable Dynamic DNS and change the settings according to your needs (see the next page).

Disable Setup Protocol

Enable this option to exclude the U8/16-IP from the setup protocol.

Security

Enable Dynamic DNS

Enables the Dynamic DNS service. This requires a configured DNS server IP address.

Dynamic DNS server

This is the server name where the U8/16-IP registers itself in regular intervals. At the time of

writing, this is a fixed setting since only dyndns.org is currently supported.

Force HTTPS

If this option is enabled, access to the web front-end is only possible using an HTTPS

connection. The U8/16-IP will not listen on the HTTP port for incoming connections.

Hostname

This is the hostname of the U8/16-IP that is provided by the Dynamic DNS Server. (Use the

whole name including the domain, e.g. testserver.dyndns.org not just the actual hostname).

If you want to create your own SSL certificate that is used to identify the U8/16-IP please refer

to the section called Certificate on page 58.

Username

KVM encryption

You have registered this username during your manual registration with the Dynamic DNS

Server. Spaces are not allowed in the nickname.

This option controls the encryption of the RFB protocol. RFB is used by the Remote Console to

transmit both the screen data to the administrator’s machine and the keyboard and mouse data

back to the host. If set to "Off" no encryption will be used. If set to "Try", the applet will attempt

to establish an encrypted connection. If connection establishment fails for any reason an

unencrypted connection will be used. If set to Force the applet tries to make an encrypted

connection. An error will be reported if connection establishment fails.

Password

The password used during manual registration with the Dynamic DNS Server.

Check time

The U8/16-IP registers itself in the Dynamic DNS server at this time.

Check interval

This is the interval for reporting again to the Dynamic DNS server by the U8/16-IP.

Note: The U8/16-IP has its own independent real time clock. Make sure the time setting of

the U8/16-IP switch is correct. (See the Section called Date and Time on page 63)

Certificate

After completing these three steps, the U8/16-IP has its own certificate that is used to identify it

to its clients.

Note: If you destroy the CSR on the U8/16-IP there is no way to get it back! In case you

deleted it by mistake, you have to repeat the three steps as described previously.

Common name

This is the network name of the U8/16-IP once it is installed in the user's network It is identical

to the name that is used to access the U8/16-IP with a web browser (without the “ http:// ”

prefix). In case the name given here and the actual network name differ, the browser will pop up

a security warning when the U8/16-IP is accessed using HTTPS.

The U8/16-IP uses the Secure Socket Layer (SSL) protocol for any encrypted network traffic

between itself and a connected client. During the connection establishment the U8/16-IP has to

expose its identity to a client using a cryptographic certificate.

Organizational unit

This field is used for specifying to which department within an organization the U8/16-IP

belongs.

This certificate and the underlying secret key is the same for all U8/16-IP units and certainly will

not match the network configuration that will be applied to the U8/16-IP by its user. The

certificate's underlying secret key is also used for securing the SSL handshake. Hence, this is a

security risk (but far better than no encryption at all).

Organization

The name of the organization to which the U8/16-IP belongs.

However, it is possible to generate and install a new certificate that is unique for a particular

U8/16-IP. In order to do this, the U8/16-IP is able to generate a new cryptographic key and the

associated Certificate Signing Request (CSR) that needs to be certified by a certification

authority (CA). A certification authority verifies that you are the person you claim you are, and

signs and issues a SSL certificate to you.

Locality/City

The city where the organization is located.

State/Province

The state or province where the organization is located.

The following steps are necessary to create and install an SSL certificate for the U8/16-IP:

Country (ISO code)

The country where the organization is located. This is the two-letter ISO code, e.g. DE for

Germany, or US for the USA.

1. Create an SSL Certificate Signing Request using the panel shown in the screen shot

above. You need to fill out a number of fields that are explained on the next page. Once

this is done, click on the Create button to initiate the Certificate Signing Request

generation. The CSR can be downloaded to your administration machine with the

Download CSR button (see the illustration on the next page).

Challenge Password

Some certification authorities require a challenge password to authorize later changes on the

certificate (e.g. revocation of the certificate). The minimal length of this password is 4

characters.

2. Send the saved CSR to a CA for certification. You will get the new certificate from the CA

after a more or less complicated traditional authentication process (depending on the

CA).

3. Upload the certificate to the U8/16-IP switch using the Upload button.

The email address of a contact person that is responsible for the U8/16-IP and its security.

Key length

This is the length of the generated key in bits. 1024 bits are sufficient for most cases. Longer

keys may result in slower response time by the U8/16-IP during connection establishment.

The U8/16-IP Serial Settings allow you to specify what device is connected to the serial port and

how to use it.

Configuration or console login

Do not use the serial port for any special function; use it only for the initial configuration

Modem

The U8/16-IP offers remote access using a telephone line in addition to the standard access

over the built-in Ethernet adapter. The modem needs to be connected to the serial interface of

the U8/16-IP.

Connecting to the U8/16-IP using a telephone line allows you to set up a dedicated point-to-

point connection from your console computer to the U8/16-IP. In other words, the U8/16-IP acts

as an Internet Service Provider (ISP) to which you can dial in. The connection is established

using the Point-to-Point Protocol (PPP). Before you connect to the U8/16-IP, make sure you

configure your console computer accordingly. For instance, on Windows based operating

systems you can configure a dial-up network connection, which defaults to the right settings like

PPP.

The Modem Settings panel allows you to configure remote access to the U8/16-IP using a

modem. The meaning of each parameter will be described below. The modem settings are part

of the serial settings panel.

Serial line speed

The speed the U8/16-IP is communicating with the modem. Most modems available today

will support the default value of 115200 bps. In case you are using an old modem and

discovering problems try to lower this speed.

Date And Time

Modem Init String

The initialization string used by the U8/16-IP to initialize the modem. The default value will

work with all modern standard modems directly connected to a telephone line. In case you

have a special modem or the modem is connected to a local telephone switch that requires

a special dial sequence in order to establish a connection to the public telephone network,

you can change this setting by entering a new string. Refer to your modem’s manual about

the AT command syntax.

Modem server IP address

This IP address will be assigned to the U8/16-IP during the PPP handshake. Since it is a

point-to-point IP connection virtually every IP address is possible but you must make sure, it

is not interfering with the IP settings of the U8/16-IP and your console computer. The default

value will work in most cases.

Modem client IP address

This IP address will be assigned to your console computer during the PPP handshake.

Since it is a point-to-point IP connection virtually every IP address is possible but you must

make sure, it is not interfering with the IP settings of the U8/16-IP switch and your console

computer. The default value will work in most cases.

Pass-through access to serial port via Telnet

Using this option, it is possible to connect an arbitrary device to the serial port and access it

(assuming it provides terminal support) via Telnet. Select the appropriate options for the serial

port and use the Telnet Console, or a standard Telnet client to connect to the U8/16-IP.

Here you can set the internal real-time clock of the U8/16-IP. You can adjust the clock manually

or use an NTP timeserver. Without a timeserver your time setting will be lost if the U8/16-IP is

powered down for more than a few minutes. To avoid this, you can use an NTP timeserver

which sets up the internal clock automatically to the current UTC time. Because the NTP server

time is always UTC, there is a setting that allows you to set up a static offset to get your local

time.

Note: The U8/16-IP does not adjust to daylight saving time automatically. So you have to set

up the UTC offset according to the local conventions of your country.

SMTP Logging enabled

Event Log

With this option, the U8/16-IP is able to send Emails to an address given by the Email address

text field in the Event Log Settings. These mails contain the same description strings as the

internal log file and the mail subject is filled with the event group of the occurred log event. In

order to use this log destination you have to specify an SMTP server that has to be reachable

from the U8/16-IP and that needs no authentication at all (<serverip>:<port>).

SNMP Logging enabled

If this is activated, the U8/16-IP sends an SNMP trap to a specified destination IP address every

time a log event occurs. If the receiver requires a community string, you can set it in the

appropriate text field. Most of the event traps only contain one descriptive string with all

information about the log event. Only authentication and host power events have a trap class

that consists of several fields with detailed information about the occurred event. To receive

these SNMP traps, any SNMP trap listener may be used.

Warning In contrast to the internal log file on the U8/16-IP, the size of the NFS log file is not

limited. Every log event will be appended to the end of the file so it grows continuously, so you

may have to delete it or move it from time to time.

Important events like a login failure or a firmware update are logged to a selection of logging

destinations. Each of those events belongs to an event group, which can be activated

separately.

In the Event Log Settings you can choose how many log entries are shown on each page.

Furthermore, you can clear the log file here.

List logging enabled

The common way to log events is to use the internal log list of the U8/16-IP. To show the log

list, click on Event Log on the Maintenance page.

Since the U8/16-IP’s system memory is used to save all the information, the maximum number

of possible log list entries is restricted to 1000 events. Every entry that exceeds this limit

overrides the oldest one.

Note: If the reset button on the HTML front end is used to restart the U8/16-IP all logging

information is saved permanently and is available after the U8/16-IP has been started. If the

U8/16-IP loses power or a hard reset is performed, all logging data will be lost. To avoid this,

use one of the log methods described below.

NFS Logging enabled

Defines an NFS server to write all logging data to a file that is located there. To write logging

data from multiple U8/16-IP units to only one NFS share, you have to define a file name that is

unique for each device. When you change the NFS settings and press Apply, the NFS share

will be mounted immediately. That means, the NFS share and the NFS server must be filled

with valid sources or you will get an error.

Unit Reset

This section allows you to reset specific parts of the device. This involves the keyboard and

mouse, the video engine and the U8/16-IP itself.

Updating the firmware is a four stage process:

1. The new firmware file is uploaded to the U8/16-IP. In order to do this you need to select the

file on your local system using the Browse button on the Upload Firmware panel. Once the

firmware file has been uploaded it is checked whether it is a valid firmware file and whether

there were any transmission errors. In case of any error the Upload Firmware function will be

aborted.

2. If everything went well you will see the Update Firmware panel. The panel shows you the

version number of the currently running firmware and the version number of the uploaded

firmware. Pressing the Update button will replace the old version with the new one.

3. After the firmware has been stored, the U8/16-IP will automatically reset itself. Half a minute

after the reset the U8/16-IP will run with the new firmware version and should be accessible.

However, you will be required to login once again.

4. Once you have logged in we recommend you delete the Temporary Internet Files from

your browser to ensure that the appearance of the web interface is correct. To do this in

Internet Explorer, select:

Tools > Internet Options > General > Delete Files

Tick the check box: Delete all offline content, and click OK

Note: The firmware update process and consistency check means that making a mistake

when updating the firmware is very unlikely. However, we recommend only experienced

users or administrators should perform the firmware update. This process is not reversible

and may take some minutes. Make sure the U8/16-IP’s power supply will not be interrupted

during the update process!

Resetting the unit itself is mainly needed to activate a newly updated firmware. It will close all

current connections to the administration console and to the Remote Console.

Tip: Should your keyboard fail to operate correctly, in the remote console, after a firmware

update please use the Reset Keyboard/Mouse option in the Maintenance section as

The whole process will take about half a minute. Resetting sub devices (e.g. the video engine)

will take a few seconds only and does not result in connections closing. To reset individual

U8/16-IP functionality, click on the Reset button.

described on page 69

Note: Only the super user is allowed to reset the U8/16-IP.

Troubleshooting

IP Access Troubleshooting

Troubleshooting

1. The remote mouse doesn’t work or is not synchronized

If none of the LED displays on the KVM Switch are illuminated, please check that the power

adapter is connected and switched on at the mains.

Make sure the mouse settings in U8/16-IP match the mouse model. Use the Intelligent

Sync option from the Mouse Handling sub menu of the Remote Console Options menu.

Before you check any further please make sure that all cables are well connected!

KVM Switch Troubleshooting

2. The remote mouse does not work correctly

Try using the Reset Keyboard/Mouse option in the Maintenance section as described on

page 69.

If the KVM Switch reacts to keyboard input from the SCROLL LOCK key with a beep signal but

you get no monitor picture displayed please check if the currently selected computer is in sleep

mode or powered down. You can try to wake up this computer by pressing the ESCAPE key

several times until the KVM Switch no longer beeps, and then pressing spacebar or RETURN

key to wake up the computer. The U8/16-IP supports VGA power save modes and suspends

the monitor signal if the currently selected computer has switched off the VGA signal.

3. The video quality is bad or the picture is grainy

Try to correct the brightness and contrast settings (see Page 33) until they are out of a

range where the picture looks grainy. Use the auto adjustment feature to correct a flickering

video.

4. Login on U8/16-IP switch fails.

Was the correct combination of user and password given? The default user name is super

and the password is pass. Furthermore, your browser must be configured to accept cookies.

Please check if your problems can be solved by resetting the KVM switch, via the push buttons

on the front panel. For cascaded systems please follow the procedures mentioned in the

CASCADING section.

5. The Remote Console window can’t connect to the U8/16-IP.

Possibly a firewall prevents access to the Remote Console. Make sure the TCP port

numbers 443 or 80 are open for incoming TCP connections. Install the latest version of Java

Virtual Machine,

1. The Monitor picture is not sharp or shows shadows

- The maximum recommended VGA cable distance is 5 metres without ghosting and

degradation.

- Make sure you have used high quality video cables with coaxial cores. If the diameter of

the cable is less then 6mm then the cable may not be high enough quality.

6. No connection can be established to the U8/16-IP.

Check whether the network connection is working in general (ping the IP address of U8/16-

IP). If not, check the network hardware. Is the U8/16-IP powered on? Check whether the IP

address of U8/16-IP switch and all other IP related settings are correct! Also verify that all

the IP infrastructure of your LAN, including routers etc., is correctly configured.

2. The maximum recommended PS/2 cable distance is 5 metres. Normally, the cable length is

based on the electronic driver capacity of your motherboards PS/2 ports. If you need longer

PS/2 distances it may be necessary to use a PS/2 extender.

7. Special key combinations, e.g. ALT+F2, ALT+F3 are intercepted by the console

system and not transmitted to the host.

3. Don’t press any keys on the keyboard while the selected computer is booting up. Otherwise

it may cause a keyboard error, or the keyboard may not be detected at the PC side.

You have to define a so-called Button Key. This can be done in the Remote Console

settings.

4. The computer boots up fine, but the keyboard doesn’t work

Make sure the keyboard works when directly plugged into the computer. Try a different

keyboard, but use standard PS/2 keyboards (some keyboards with extra multimedia keys

may not be supported).

8. In the browser the U8/16-IP switch pages are inconsistent.

Clear Temporary Internet Files from your browser. To do this in Internet Explorer, select:

Tools > Internet Options > General > Delete Files

5. The Mouse is not detected during PC boot up

- Make sure the mouse works when directly plugged into the computer. You have to install

the appropriate mouse driver on all connected computers!

Tick the check box: Delete all offline content, and click OK

- Make sure the mouse is a true PS/2 mouse. A combo mouse will work just as long as it is

set for PS/2 mode with the correct adapter. Try a different mouse.

9. Windows XP doesn’t awake from standby mode

This could be a Windows XP problem. Try not to move the mouse while XP goes into

standby mode.

- Some advanced mice like radio frequency mice, 5 button mice and scroll wheel mice use

very uncommon proprietary signals. Although LINDY has carefully checked for the highest

compatibility, we cannot guarantee that the U8/16-IP will work with all known mice,

especially those developed and produced after the U8/16-IP’s introduction.

- Avoid moving the mouse or pressing the mouse buttons when switching ports.

- Avoid switching ports during the PC shut down process.

10.Every time I open a dialog box with some buttons, the mouse pointers are not

synchronous anymore

Please check if you have an option like ‘Automatically move mouse pointer to the default

button of dialog Unites’ enabled in the mouse settings of the operating system. This option

needs to be disabled.

6. If you have forgotten the OSD “password” please contact LINDY.
