2. Introduction
Thank you for purchasing IP-KVM switch. IP-KVM switch can save your MONEY, TIME, SPACE,
EQUIPMENT and POWER. IP-KVM switch defines a new class of remote KVM access devices.
IP-KVM switch combines digital remote KVM access via IP networks with comprehensive and
integrated system management.
IP-KVM switch provides convenient, remote KVM access and control via LAN or Internet. It captures,
digitizes, and compresses video signal and transmits it with keyboard and mouse signals to and from
a remote computer. IP-KVM switch provides a non-intrusive solution for remote access and control.
Remote access and control software runs on its embedded processors only but not on mission-critical
servers, so that there is no interference with server operation or impact on network performance.
Furthermore, IP-KVM switch offers additional remote power management with the help of optional
available device.
IP-KVM switch supports consoles consisting of PS/2 style keyboards and mouse and HDDB 15 video
output. IP-KVM switch will automatically detect the current video mode of the console, however
manual fine-tuning is recommended to receive the best video quality. IP-KVM switch will accept video
streams up to 110 MHz dot clock. This results in a screen resolution of 1280x1024 pixels with a frame
rate of 60 Hz.
2.1. When the server is up and running
IP-KVM switch gives you a full control over the remote server. The Management Console allows you
to access the remote server’s graphics, keyboard and mouse and to send special commands to the
server. You can also perform periodic maintenance of the server. Using the Console Redirection
Service, you are able to do the following:
I. Reboot the system
II. Watch the boot process.
III. Boot the system from a separate partition to load the diagnostic environment.
IV. Run special diagnostic programs.
2.2. When the server is dead
Obviously, fixing hardware defects is not possible through a remote management device.
Nevertheless IP-KVM switch gives the administrator valuable information about the type of a hardware
failure. Serious hardware failures can be categorized into five different categories with different
chances to happen:
I. Hard disk failure 50%
II. Power cable detached, power supply failure 28%
III. CPU, Controller, main board failure 10%
IV. CPU fan failure 8%
V. RAM failure 4%
Using IP-KVM switch, administrators can determine which kind of serious hardware failure has
occurred (See table 2-1).

Warning
If the DHCP connection fails on boot up, the IP-KVM switch will not have an IP
address.
If this initial configuration does not meet your requirements, the following describes the initial IP
configuration that is necessary to access the IP-KVM switch for the first time.
4.1.1 Initial configuration via DHCP server
By default, the IP-KVM switch will try to contact a DHCP server in the subnet to which it is
physically connected. If a DHCP server is found, it may provide a valid IP address, gateway
address and net mask. Before you connect the device to your local subnet, be sure to complete
the corresponding configuration of your DHCP server. It is recommended to configure a fixed IP
assignment to the MAC address of the IP-KVM switch. You can find the MAC address labeled on
the bottom side of the metal housing.
If this initial configuration does not meet your local requirements, use the setup tool to adjust the
values to your needs. The setup tool can be found on the CD ROM delivered with this package.
You can follow the procedure described below.
IP-KVM switch Setup Tool
MAC Address Detection
Connect the IP-KVM switch to your computer either via local network, or via USB. Start the
setup tool from the CD ROM on the computer that the IP-KVM switch is installed. Depending on
the connection (USB or network), the device detection is different. A window opens as seen
below:

With this option, you can specify whether the IP-KVM switch should get its network settings
from a DHCP or BOOTP server. For DHCP, enter “dhcp”, and for BOOTP enter “bootp”. If you
do not specify any of these, the IP autoconfiguration is disabled and subsequently you will be
asked for the following network settings.
IP address
The IP address the IP-KVM switch uses. This option is only available if IP autoconfiguration is
disabled.
Net mask
The net mask of the connected IP subnet. This option is only available if IP autoconfiguration is
disabled.
Gateway address
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. This option is only available if IP autoconfiguration is disabled.
4.1.3 Keyboard, Mouse and Video configuration
Between the IP-KVM switch 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.

Single port KVM over IP switch
4.1.3.1 IP-KVM switch keyboard settings
The IP-KVM switch settings for the host's keyboard type have to be corrected in order to
make the remote keyboard work properly. Check the settings in the IP-KVM switch front-end.
See section 6.4.3 in details.
4.1.3.2 Remote Mouse Settings
A common problem with KVM devices is the synchronization between the local and remote
mouse cursors. The IP-KVM switch addresses this situation with an intelligent
synchronization algorithm. There are two mouse modes available on the IP-KVM switch.
Auto mouse speed
The automatic mouse speed mode tries to detect the speed and acceleration settings of
the host system automatically. See the section below for a more detailed explanation.
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 with the scaling. It should be noted that this works only when mouse
acceleration is turned off on the remote system.
4.1.3.3 Auto mouse speed and mouse synchronization
The automatic mouse speed mode performs the speed detection during mouse
synchronization. Whenever the mouse does not move correctly, there are two ways for
re-synchronizing local and remote mouse:
Fast Sync
The fast synchronization is used to correct a temporary, but fixed skew. Choose the
option using the Remote Console options menu or press the mouse synchronization
hotkey sequence in case you defined one.
Intelligent Sync
If the fast sync does not work or the mouse settings have been changed on the host
system, use the intelligent resynchronization. This method takes more time than the fast
one and can be accessed with the appropriate item in the Remote Console option menu.
The intelligent synchronization requires a correctly adjusted picture. Use the auto
adjustment function or the 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
changed recently.
Note: At first start, if the local mouse pointer is not synchronized with
the remote mouse pointer, press the Auto Adjust Button once.
4.1.3.4 Host system mouse settings
The host's operating system knows various settings from the mouse driver.
Warning
The following limitations do not apply in case of USB and Mouse Type “MS Windows
2000 and newer”.
18

Single port KVM over IP switch
While the IP-KVM switch works with accelerated mice and is able to synchronize the local
with the remote mouse pointer, there are the following limitations, which may prevent this
synchronization from working properly:
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.
Windows XP Mouse Settings
Windows XP knows a setting named “improve mouse acceleration”, which has to be
deactivated.
Active Desktop
If the Active Desktop feature of Microsoft Windows is enabled do not use a plain
background. Instead, use some kind of wallpaper. As an alternative, you could also
disable the Active Desktop completely.
Navigate your mouse pointer into the upper left corner of the applet
screen and move it slightly forth and back. Thus the mouse will be
resynchronized. If re-synchronizing fails, disable the mouse acceleration
and repeat the procedure.
4.1.3.5 Single and Double Mouse Mode
The information above applies to the Double Mouse Mode, where remote and local
mouse pointers are visible and need to by synchronize. The IP-KVM switch also
features another mode, the 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, it is necessary to define a mouse hotkey in the Remote
Console Settings Panel. Press this key to free the captured local mouse pointer.
4.1.3.6 Recommended Mouse Settings
For the different operating systems we can give the following advice:
MS Windows 2000/2003 (Professional and Server), XP
In general, we recommend the usage of a mouse via USB. Choose USB
without Mouse Sync. For a PS/2 mouse choose Auto Mouse Speed. For XP
disable the option enhance pointer precision in the Control Panel.
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.
MAC OS X
We recommend using the Single Mouse Mode.

4.1.3.7 Video Modes
The IP-KVM 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 IP-KVM switch may not be able to detect them. We recommend using any of
the standard VESA video modes, instead.

5. Usage
5.1 Prerequisites
The IP-KVM switch features an embedded operating system and applications offering a variety
of standardized interfaces. This chapter will describe both these interfaces, and the way to use
them in a more detailed manner. The interfaces are accessed using the TCP/IP protocol family,
thus they can be accessed using the built-in Ethernet adapter.
The following interfaces are supported:
HTTP/HTTPS
Full access is provided by the embedded web server. The IP-KVM switch environment can
be entirely managed using a standard web browser. You can access the IP-KVM switch
using the insecure HTTP protocol, or using the encrypted HTTPS protocol. Whenever
possible, use HTTPS.
Telnet
A standard Telnet client can be used to access an arbitrary device connected to the IP-KVM
switch's serial port via a terminal mode.
The primary interface of the IP-KVM switch is the HTTP interface. This is covered extensively
in this chapter. Other interfaces are addressed in subtopics.
In order to use the Remote Console window of your managed host system, the browser has to
come with a Java Runtime Environment version 1.1 or higher. If the browser has no Java support
(such as on a small handheld device), you are still able to maintain your remote host system
using the administration forms displayed by the browser itself.
Important: We recommend installing a Sun JVM 1.4.
For an insecure connection to the IP-KVM switch, we can recommend the following browsers:
• Microsoft Internet Explorer version 6.0 or higher on Windows 98, Windows ME, Windows 2000
and Windows XP
• Netscape Navigator 7.0 or Mozilla 1.6 on Windows 98, Windows ME, Windows 2000, Windows
XP, Linux and other UNIX-like Operating Systems
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 of the old browsers do not have a strong 128 Bit encryption algorithm.
Using the Internet Explorer, open the menu entry “?” and “Info” to read about the key length that
is currently activated. The dialog box contains a link that leads you to information on how to
upgrade your browser to a state of the art encryption scheme. Figure 5-1 shows the dialog box
presented by the Internet Explorer 6.0.

Launch your web browser. Direct it to the address of your IP-KVM switch, which you
configured during the installation process. The address used might be a plain IP address or a
host and domain name, in the case where you have given your IP-KVM switch a symbolic
name in the DNS. For instance, type the following in the address line of your browser when
establishing an unsecured connection:

The user “ super ” is not allowed to login via the serial interface of the IP-KVM switch.
Warning
Please make sure to change the super user password immediately after you have
installed and accessed your IP-KVM switch for the first time. Not changing the pass
phrase for the super user is a severe security risk and might result in unauthorized
access to the IP-KVM switch and to the host system including all possible
consequences!
Warning
Your web browser has to accept cookies, or else login is not possible.
Navigation
Having logged into the IP-KVM switch successfully, the main page of the IP-KVM switch
appears (see Figure 5-3). This page consists of three parts; each of them contains specific
information. The buttons on the upper side allow you to navigate within the front end (see
Table 5-2 for details). The lower left frame contains a navigation bar and allows you to switch
between the different sections of the IP-KVM switch. Within the right frame, task-specific

5.3 The Remote Console
General description
The Remote Console is the redirected screen, keyboard and mouse of the remote host
system that IP-KVM switch controls.
Figure 5-4. Remote Console
The Remote Console window is a Java Applet that tries to establish its own TCP connection
to the IP-KVM switch. The protocol that is run over this connection is neither HTTP or HTTPS,
but RFB (Remote Frame Buffer Protocol). Currently, RFB tries 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, in case you have a private internal network, your NAT (Network Address
Translation) settings have to be configured accordingly.
In case the IP-KVM switch is connected to your local network environment and your
connection to the Internet is available using a proxy server only without NAT being
24

Single port KVM over IP switch
configured, the Remote Console is very unlikely to be able to establish the according
connection. This is because today's web proxies are not capable of relaying the RFB
protocol.
In case of problems, please consult your network administrator in order to provide an
appropriate network environment.
5.4 Main Window
Starting the Remote Console opens an additional window. It displays the screen content of
your host system. The Remote Console will behave exactly in the same way as if you were
sitting directly in front of the screen of your remote system. That means keyboard and mouse
can be used in the usual way. However, be aware of the fact that the remote system will react
to keyboard and mouse actions with a slight delay. The delay depends on the bandwidth of
the line which you use to connect to the IP-KVM switch.
With respect to the keyboard, the very exact remote representation might lead to some
confusion as 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, 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.
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.
Warning
In difference to the remote host system, the Remote Console window on your local
window system is just one window among others. In order to make keyboard and
mouse work, your Remote Console window must have the local input focus.
5.4.1 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.

the local with the remote mouse cursor. 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.
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
and need to be synchronized). Single mouse mode is only available if using SUN JVM
1.3 or higher.

A short description 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, and monitoring is possible.
• 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.
A change in the access mode is also visible in the status line (see Figure 5-7).

• Mouse Handling
The submenu for mouse handling offers two options for synchronizing the local and the
remote mouse pointer.
Fast Sync --
The fast synchronization is used to correct a temporary, but fixed skew.
Intelligent Sync --
Use this option if the fast sync does not work or the mouse settings have been
changed on the host system.

• Video Settings
Opens a panel for changing the IP-KVM switch video settings. IP-KVM switch features
two different dialogs, which influence the video settings.
Video Settings through the HTML-Frontend
To enable local video port, select this option. This option decides if the local video
output of IP-KVM switch is active and passing through the incoming signal from the
host system.
The option Noise Filter defines how IP-KVM switch 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.

Telnet Console
Figure 6-2. Telnet Console
The IP-KVM switch firmware features a Telnet server that enables a user to connect via a
standard Telnet client. In case the Telnet program is using a VT 100, VT 102 or VT 220
terminal or an according emulation, it is even possible to perform a console redirection as
long as the IP-KVM switch host machine is using a text mode screen resolution.
Connecting to the IP-KVM switch 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 IP-KVM switch. This will
prompt for 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 according functions of
the web interface.
Once you have successfully logged into the IP-KVM switch a command line will be presented
and you can enter according 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.

User select box
This selection 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 is 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.
Manually
Allows to adjust both compression rate and the colour depth individually. Depending
on the selected compression rate the data stream between the IP-KVM switch 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 while several
users are accessing the IP-KVM switch simultaneously.
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 gray scales) are
recommended for typical desktop interfaces. Photo-like pictures have best results
with 4 Bit (16 gray scales). 1 Bit colour depth (black/white) should only be used for
extremely slow network connections.

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 the Internet Explorer, or the Sun JVM if it is configured this way. Use of the
Sun JVM may also be forced (see below).
Sun Microsystems Java Browser Plugin
Instructs the web browser of your administration system to use the JVM of Sun
Microsystems. 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 according
dialogs with “yes” . The download volume is around 11 Mbytes. The advantage of
downloading Sun's JVM lays in providing a stable and identical Java Virtual Machine
across different platforms. The Remote Console software is optimized for this JVM
versions and offers wider range of functionality when run in SUN's JVM. (Hint: If you
are connected over a slow connection to the Internet you can also pre-install the JVM
on your administration machine. The software is available on the CD ROM that is
delivered along with the IP-KVM switch.)
ActiveX control
This option instructs the web browser to use the ActiveX-Control of the KVM Vision
Viewer, an application available separately. You have to install this program on your
local system, please refer to the manual of the KVM vision viewer for further
information. This option only works with Microsoft Internet Explorer on Win32

system of the Remote Console is unconditionally catching this keystroke already. Typical
examples are “Control+Alt+Delete” on Windows and DOS, what is always caught, or
“ Control+Backspace ” on Linux for terminating the X-Server. The syntax to define a new
Button Key is as follows:
[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 concatenated 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 keypresses
and -releases. The star inserts a pause with duration of 100 milliseconds.

Host Interface
Enables a certain interface the mouse is connected to. You can choose between “Auto”
for automatic detection, “USB” for an USB mouse, and “PS/2” for a PS/2 mouse.
Warning
To use the USB and/or PS/2 interface you need a 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 the card will select “ USB ” if available or otherwise falls back to “ PS/2 ”.
To get 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
extendend by three additional windows keys, “Generic 106-Key PC” for a japanese
keyboard, and “Apple Macintosh” for the Apple Macintosh.

or OS X. In “MS Windows 2000 or newer” mode the remote mouse is always
synchronized with the local mouse.
Mouse Speed
• Auto mouse speed
Use this option if the mouse settings on host use an additional acceleration setting. The
IP-KVM switch 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.
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.

Single port KVM over IP switch
Figure 6-21. Dynamic DNS Scenario
The IP-KVM switch 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 IP-KVM switch 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 card.
The administrator has to register an IP-KVM switch 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 to the registration process. This account information
together with the hostname is needed in order to determine the IP address of the registered
IP-KVM switch.
You have to perform the following steps in order to enable Dynamic DNS:
• Make sure that the LAN interface of the IP-KVM switch is properly configured.
• Enter the Dynamic DNS Settings configuration dialog as shown in Figure 6-20.
• Enable Dynamic DNS and change the settings according to your needs (see below).
Enable Dynamic DNS
This enables the Dynamic DNS service. This requires a configured DNS server IP
address.
Dynamic DNS server
This is the server name where IP-KVM switch registers itself in regular intervals.
Currently, this is a fixed setting since only dyndns.org is supported for now.
Hostname
This is the hostname of the IP-KVM switch 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).

Check interval
This is the interval for reporting again to the Dynamic DNS server by the IP-KVM switch.
Warning
The IP-KVM switch has its own independent real time clock. Make sure the time
setting of the IP-KVM switch is correct. (see the Section called Date And Time )
6.5.3 Security
Figure 6-22. Device Security
Force HTTPS
If this option is enabled access to the web front-end is only possible using an HTTPS
connection. The IP-KVM switch will not listen on the HTTP port for incoming connections.
In case you want to create your own SSL certificate that is used to identify the IP-KVM
switch refer to the Section called Certificate.
KVM encryption
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 machine and keyboard and
mouse data back to the host. If set to `Off' no encryption will be used. If set to `Try' the

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 in case connection establishment fails.
6.5.4 Certificate
Figure 6-23. Certificate Settings
The IP-KVM switch uses the Secure Socket Layer (SSL) protocol for any encrypted network
traffic between itself and a connected client. During the connection establishment the
IP-KVM switch has to expose its identity to a client using a cryptographic certificate. Upon
delivery, this certificate and the underlying secret key is the same for all IP-KVM switch ever
produced and certainly will not match the network configuration that will be applied to the
IP-KVM switch cards 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).
However, it is possible to generate and install a new certificate that is unique for a particular
IP-KVM switch card. In order to do that, the IP-KVM switch 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 who you claim you are, and signs and issues a SSL certificate to you.
The following steps are necessary to create and install a SSL certificate for the IP-KVM
switch:
• Create a SSL Certificate Signing Request using the panel shown in Figure 6-23. You need
to fill out a number of fields that are explained below. Once this is done, click on the button
“ Create ” which will initiate the Certificate Signing Request generation. The CSR can be

downloaded to your administration machine with the “Download CSR” button (see Figure
6-24).
• 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).
• Upload the certificate to the IP-KVM switch using the “ Upload ” button as shown in Figure
6-24.
Figure 6-24. SSL Certificate Upload
After completing these three steps, the IP-KVM switch has its own certificate that is used for
identifying the card to its clients.
Warning
If you destroy the CSR on the IP-KVM switch there is no way to get it back! In case
you deleted it by mistake, you have to repeat the three steps as described above.

Single port KVM over IP switch
Configuration or console login
Do not use the serial port for any special function, use it only for the initial configuration
(see Table 4-1 ).
Modem
The IP-KVM switch 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 IP-KVM switch .
Logically, connecting to the IP-KVM switch using a telephone line means nothing else
than building up a dedicated point-to-point connection from your console computer to the
IP-KVM switch. In other words, the IP-KVM switch 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 IP-KVM switch, make sure to 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 the remote access to the IP-KVM
switch 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 IP-KVM switch is communicating with the modem. Most of all 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.
Modem Init String
The initialization string used by the IP-KVM switch 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 giving a
new string. Refer to the modem's manual about the AT command syntax.
Modem server IP address
This IP address will be assigned to the IP-KVM switch itself 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
IP-KVM switch 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
IP-KVM switch and your console computer. The default value will work in most cases.

Passthrough 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
IP-KVM switch .
IPM 220-L (Inline Power Module)
This is an optionally available external module to switch power of a single system by
putting it in the power supply line of the controlled system.
6.5.6 Date And Time
Figure 6-27. Date and Time
This link refers to a page, where the internal real-time clock of the IP-KVM switch can be set
up (see Figure 6-27). You have the possibility to adjust the clock manually, or to use a NTP
timeserver. Without a timeserver, your time setting will not be persistent, so you have to
adjust it again, after IP-KVM switch loses power for more than a few minutes. To avoid this,
you can use a NTP timeserver, which sets up the internal clock automatically to the current
UTC time. Because NTP server time is always UTC, there is a setting that allows you to set
up a static offset to get your local time.
Warning
There is currently no way to adjust the daylight saving time automatically. So you
have to set up the UTC offset twice a year properly to the local rules of your country.

6.5.7 Event Log
Figure 6-29. Event Log
Important events like a login failure or a firmware update are logged to a selection of logging
destinations (see Figure 6-29). Each of those events belongs to an event group, which can
be activated separately.
The common way to log events is to use the internal log list of the IP-KVM switch. To show
the log list, click on “Event Log” on the “Maintenance” page. 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 IP-KVM switch . To
show the log list, click on “Event Log” on the “Maintenance” page.
Since the IP-KVM switch's system memory is used to save all the information, the
maximum number of possible log list entries is restricted to 1.000 events. Every entry that
exceeds this limit overrides the oldest one, automatically.
Warning
If the reset button on the HTML frontend is used to restart the IP-KVM switch, all
logging information is saved permanently and is available after the IP-KVM
switch has been started. If the IP-KVM switch loses power or a hard reset is
performed, all logging data will be lost. To avoid this, use one of the following log
methods.

Single port KVM over IP switch
NFS Logging enabled
Define a NFS server, where a directory or a static link have to be exported, to write all
logging data to a file that is located there. To write logging data from more than one
IP-KVM switch devices 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 the button “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 message.
SMTP Logging enabled
With this option, the IP-KVM switch 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 a SMTP
server, that has to be reachable from the IP-KVM switch device and that needs no
authentication at all (<serverip>:<port>).
SNMP Logging enabled
If this is activated, the IP-KVM switch sends a 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 an own trap class that consists of several fields with detailed information about the
occurred event. To receive this SNMP traps, any SNMP trap listener may be used.
Warning
In contrast to the internal log file on the IP-KVM switch, 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 and you may have to delete it or move it away from time to time.

6.6.2 Update Firmware
Figure 6-33. Update Firmware
The IP-KVM switch is a complete standalone computer. The software it runs is called the
firmware. The firmware of the IP-KVM switch can be updated remotely in order to install new
functionality or special features.
A new firmware update is a binary file which will be sent to you by email or which you can
download from the supplier web site. If the firmware file is compressed (file suffix .zip) then
you must unzip it before you can proceed. Under the Windows operating system you may
provide a program called unzip.
Before you can start updating the firmware of your IP-KVM switch the new uncompressed
firmware file has to be accessible on the system that you use for connecting to the IP-KVM
switch.
Updating the firmware is a three-stage process:
• Firstly, the new firmware file is uploaded onto the IP-KVM switch. In order to do that you
need to select the file on your local system using the button “ Browse ” of 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.
• Secondly, if everything went well, you 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 button “Update” will store the new version and substitute
the old one completely.

Warning
This process is not reversible and might take some minutes. Make sure the IP-KVM
switch 's power supply will not be interrupted during the update process, because
this may cause an unusable card.
• Thirdly, after the firmware has been stored, the panel will request you to reset the IP-KVM
switch manually. Half a minute after the reset, the IP-KVM switch will run with the new
firmware version and should be accessible. However, you are requested to login once
again.
Warning
The three-stage firmware update process and complete consistency check are
making a mistake in updating the firmware almost impossible. However, only
experienced staff members or administrators should perform a firmware update.
Make sure the IP-KVM switch 's power supply will not be interrupted!

7. Troubleshooting
Q 001: The remote mouse doesn’t work or is not synchronous
A 001: Make sure the mouse settings in IP-KVM switch match the mouse model. There are some
circumstances where the mouse synchronization process could behave incorrectly, refer to Section
5.3.3 for further explanation.
Q 002: The video quality is bad or the picture is grainy
A 002: Try to correct the brightness and contrast settings (see Section 5.3.4) until they are out of a
range where the picture looks grainy. Use the auto adjustment feature to correct a flickering video.
Q 003: Login on IP-KVM switch fails.
A 003: Was the correct combination of user and password given? On delivery, the user ”super” has
the password ”pass”. Moreover your browser must be configured to accept cookies.
Q 004: The Remote Console window can’t connect to IP-KVM switch.
A 004: Possibly a firewall prevents access to the Remote Console. Make sure the TCP port numbers
443 or 80 are open for incoming TCP connection establishments.
Q 005: No connection can be established to IP-KVM switch.
A 005: Check whether the network connection is working in general (ping the IP address of IP-KVM
switch). If not, check network hardware. Is IP-KVM switch powered on? Check whether the IP address
of IP-KVM switch and all other IP related settings are correct! Also verify that all the IP infrastructure of
your LAN, like routers etc., is correctly configured. Without a ping functioning, IP-KVM switch can’t
work either.
Q 006: Special key combinations, e.g. ALT+F2, ALT+F3 are intercepted by the console system and
not transmitted to the host.
A 006: You have to define a so-called ’Button Key’. This can be done in the Remote Console settings.
Q 007: In the browser the IP-KVM switch pages are inconsistent or chaotic.
A 007: Make sure your browser cache settings are feasible. Especially make sure the cache settings
are not set to something like ”never check for newer pages”. Otherwise IP-KVM switch pages may be
loaded from your browser cache and not from the card.
Q 008: Windows XP doesn’t awake from standby mode
A 008: This is possibly a Windows XP problem. Try not to move the mouse while XP goes in standby
mode.
Q 009: Using MacOS X a HTTPS connection fails
A 009: You have to install the IP-KVM switch certificate using our certificate installer, available on the
utility CD. Please refer to the instructions on this CD for further information how to install the
certificate.
Q 010: Can’t upload the signed certificate in MacOS X
A 010: If an ’internal error’ occurs while uploading the signed certificate either change the extension of
the file to .txt or add a file helper using the Internet Explorer preferences for this type of file. Make sure
that the encoding is plain text and the checkbox ’use for outgoing’ is checked. Another possibility is to
use a Mozilla based browser.

B. Key Codes
Table C.1 shows the key codes used to defines keystrokes or hotkeys for several functions.
Please note that these key codes do not represent necessarily key characters that are used on
international keyboards. They name a key on a standard 104 key PC keyboard with an US
English language mapping. The layout for this keyboard is shown in Figure C.1. However, most
modifier keys and other alphanumeric keys used for hotkey purposes in application programs are
on an identical position, no matter what language mapping you are using. Some of the keys have
aliases also, means they can be named by 2 key codes (separated by comma in the table).
