Password
super (factory default)
pass (factory default)
Changing these settings to user specific values is strongly recommended
and can be done on the User Management page (see the Section called
Users and Groups in Chapter 6).
Remote Console
The Remote Console is the redirected screen, keyboard and mouse of the remote host system to
which IP-KVM switch is installed. The web browser which is used for accessing IP-KVM switch has to
supply a Java Runtime Environment version 1.1 or higher. However, it is strongly recommended to
install Sun JVM 1.4. The Remote Console will behave exactly the same way as if you were sitting
directly in front of the screen of your remote system. That means that both the keyboard and mouse
can be used in the usual way. Open the console by selecting the preview picture on the main site of
the HTML front end. Figure 1-2 shows the top of the Remote Console.

2. Introduction
Thank you for purchasing PS/2 IP-KVM switch. PS/2 IP-KVM switch can save your MONEY, TIME,
SPACE, EQUIPMENT and POWER. PS/2 IP-KVM switch defines a new class of remote KVM access
devices. PS/2 IP-KVM switch combines an 8/16/32-port KVM switch with digital remote KVM access
via IP networks and comprehensive system management.
PS/2 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. PS/2 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, PS/2 IP-KVM switch offers additional remote power management with the help of
optional available device.
PS/2 IP-KVM switch supports consoles consisting of PS/2 style keyboards and mouse, and HD 15
video output. PS/2 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. PS/2 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
PS/2 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 sever is dead
Obviously, fixing hardware defects is not possible through using a remote management device.
Nevertheless PS/2 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 PS/2 IP-KVM switch, administrators can determine which kind of serious hardware failure has
occurred (See table 2.1).

8/16 PS/2 KVM over IP switch
4.1.3.1 PS/2 IP-KVM switch keyboard settings
The PS/2 IP-KVM switch settings for the host's keyboard type have to be correct in order to
make the remote keyboard work properly. Check the settings in the PS/2 IP-KVM switch
front-end. See 6.3.3 for 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 PS/2 IP-KVM switch addresses this situation with an intelligent
synchronization algorithm. There are two mouse modes available on the PS/2 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”.

8/16 PS/2 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 PS/2 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 PS/2 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 PS/2 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 PS/2 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 PS/2 IP-KVM switch environment
can be entirely managed using a standard web browser. You can access the PS/2 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 PS/2
IP-KVM switch's serial port via a terminal mode.
The primary interface of the PS/2 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 PS/2 IP-KVM switch, we can recommend the following
browsers :
• Microsoft Internet Explorer version 5.0 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.

Newer web browsers do support strong encryption on default.
5.2 Using PS/2 KVM over IP switch as a KVM switch
The power on state of 8/16 port PS/2 KVM over IP switch:
When you power on KVM switch, it will ask you the password, the default password value is
eight zero –“ 00000000 “. Please key in eight zero and enter the same value at retype field.
Note: Before you are not familiar with the operation of OSD manual, please don’t change the
password – i.e. keep default eight zero (00000000) value. Otherwise, if you have set the
password and unfortunately forget the password, you need send it back to your distributor for
maintaining the password.

5.4 The Remote Console
General description
The Remote Console is the redirected screen, keyboard and mouse of the remote host
system that PS/2 IP-KVM switch controls.
Figure 5-5. Remote Console
The Remote Console window is a Java Applet that tries to establish its own TCP connection
to the PS/2 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 PS/2 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
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.

5.5 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 PS/2 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.
5.5.1 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.

terminal or an according emulation, it is even possible to perform a console redirection as
long as the PS/2 IP-KVM switch host machine is using a text mode screen resolution.
Connecting to the PS/2 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 PS/2 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 PS/2 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.
The following list shows the according command mode command syntax and their usage.

8/16 PS/2 KVM over IP switch
The PS/2 IP-KVM switch comes with 2 pre-configured user accounts that have fixed
permissions. The account super has all possible rights to configure the device and to use all
functions PS/2 IP-KVM switch offers. The account “user” has only the permission to open
and use the Remote Console. Even his user name and password can only be changed by
the super account.
Upon delivery, both accounts have the password pass. Make sure to change these
passwords immediately after you have installed and firstly accessed your PS/2 IP-KVM
switch.
While the “user” account never sees the following options, the user “super” account can
change the name and password for both accounts.
Existing users
Select an existing user for modification. Once a user has been selected, click the lookup

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 PS/2 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 PS/2 IP-KVM switch simultaneously.
The standard color depth is 16 Bit (65536 colors). The other color 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 color depth. At lower bandwidths
only 4 Bit (16 colors) 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 color
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 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 PS/2 IP-KVM switch.)
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 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
Button Keys allow 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 ” 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:
41
Download from Www.Somanuals.com. All Manuals Search And Download.
8/16 PS/2 KVM over IP switch
[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 key presses
and -releases. The star inserts a pause with duration of 100 milliseconds.
6.3.2 Keyboard/Mouse
Figure 6-17. Keyboard and Mouse Settings
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

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.
USB Mouse Type
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.
Mouse Speed
• Auto mouse speed
Use this option if the mouse settings on host use an additional acceleration setting. The
PS/2 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.
To set the options, click on the button “Apply”.

6.4.2 Dynamic DNS
Figure 6-20. Dynamic DNS
A freely available Dynamic DNS service (dyndns.org) can be used in the following scenario
(see Figure 6-21):
Figure 6-21. Dynamic DNS Scenario
The PS/2 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 PS/2 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 a PS/2 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

8/16 PS/2 KVM over IP switch
together with the hostname is needed in order to determine the IP address of the registered
PS/2 IP-KVM switch.
You have to perform the following steps in order to enable Dynamic DNS:
• Make sure that the LAN interface of the PS/2 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 PS/2 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 PS/2 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).
Username
You have registered this username during your manual registration with the Dynamic
DNS Server. Spaces are not allowed in the Nickname.
Password
You have used this password during your manual registration with the Dynamic DNS
Server.
Check time
The PS/2 IP-KVM switch card 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 PS/2 IP-KVM
switch.
Warning
The PS/2 IP-KVM switch has its own independent real time clock. Make sure the time
setting of the PS/2 IP-KVM switch is correct. (See the Section called Date And Time)

If this option is enabled access to the web front-end is only possible using an HTTPS
connection. The PS/2 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 PS/2
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
applet tries to make an encrypted connection. In case 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 in case connection establishment fails.

6.4.4 Certificate
Figure 6-23. Certificate Settings
The PS/2 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 PS/2 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 PS/2 IP-KVM
switch ever produced and certainly will not match the network configuration that will be
applied to the PS/2 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
PS/2 IP-KVM switch card. In order to do that, the PS/2 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 PS/2 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 PS/2 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 PS/2 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 PS/2 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.
Common name
This is the network name of the PS/2 IP-KVM switch once it is installed in the user's
network (usually the fully qualified domain name). It is identical to the name that is used
case the name given here and the actual network name differ, the browser will pop up a
security warning when the PS/2 IP-KVM switch is accessed using HTTPS.

8/16 PS/2 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 PS/2 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 PS/2 IP-KVM switch .
Logically, connecting to the PS/2 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 PS/2 IP-KVM switch. In other words, the PS/2 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 PS/2 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 PS/2
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 PS/2 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 PS/2 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 PS/2 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 PS/2
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 PS/2
IP-KVM switch and your console computer. The default value will work in most cases.

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 PS/2
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.
6.4.6 Date And Time
Figure 6-27. Date and Time
This link refers to a page, where the internal real-time clock of the PS/2 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 PS/2 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.

6.4.7 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 PS/2 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 PS/2 IP-KVM switch .
To show the log list, click on “Event Log” on the “Maintenance” page.
Since the PS/2 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 front-end is used to restart the PS/2 IP-KVM switch, all
logging information is saved permanently and is available after the PS/2 IP-KVM switch has
been started. If the PS/2 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.
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 PS/2
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” ,
54
Download from Www.Somanuals.com. All Manuals Search And Download.
8/16 PS/2 KVM over IP switch
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 PS/2 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 PS/2 IP-KVM switch device and that needs no
authentication at all (<serverip>:<port>).
SNMP Logging enabled
If this is activated, the PS/2 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 PS/2 IP-KVM switch, the size of the NFS log

Figure 6-32 displays the IP-KVM activity. From left to right the connected user(s), its IP
address (from which host the user comes from) and its activity status is displayed. RC
means that the Remote Console is open. If the Remote Console is opened in exclusive mode
the term (exclusive mode) is added. For more information about this option see the Section
called Remote Console Control Bar in Chapter 5. To display the user activity the last column
contains either the term active for an active user or 20 min idle for a user who is inactive for a
certain amount of time.
Reset Functions
This section allows you to reset specific parts of the device. Currently this involves the video
engine and the PS/2 IP-KVM switch itself. Resetting the card 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. The whole process will take about half a minute.
Resetting sub devices (e.g. video engine) will take some seconds only and do not result in
closing connections.

6.5.3 Update Firmware
Figure 6-33. Update Firmware
The PS/2 IP-KVM switch is a complete standalone computer. The software it runs is called
the firmware. The firmware of the PS/2 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 PS/2 IP-KVM switch the new
uncompressed firmware file has to be accessible on the system that you use for connecting
to the PS/2 IP-KVM switch.
Updating the firmware is a three-stage process:
• Firstly, the new firmware file is uploaded onto the PS/2 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 PS/2
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 PS/2
IP-KVM switch manually. Half a minute after the reset, the PS/2 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 PS/2 IP-KVM switch 's power supply will not be interrupted!

1. Ensure that all cables are well seated. Label all of cables with the number for each respective
computer to avoid confusion.
2. The recommended VGA cable of PC port distance is 5 meters maximum without ghosting and
degradation. Normally, the cable length is based on driver capacity of your VGA card. If you need
longer VGA cable, please use VGA extender to accomplish your applications.
3. The recommended PS/2 cable of PC port distance is 5 meters maximum. Normally, the cable
length is based on driver capacity of your motherboard PS/2 port. If you need longer PS/2 cable,
please use PS/2 extender to accomplish your applications.
4. The Power Jack polarity is center positive and the power adapter need be DC5V, 2.5A.
5. Don’t press any keys on the keyboard while the selected computer is booting up. Otherwise, it
might cause the keyboard error or keyboard is not detected at PC side.
6. The computer boot up fine, but keyboard doesn’t work

Avoiding switching ports during shutting down the PC process.
When you switch one PC port to another PC port, the best scan time setting need to be set to 5
sec. or more. Normally, the VGA monitor change one resolution mode to another will take one or
two seconds. So, the scan time is not recommended to below 5 seconds.
8. The power switch is off, but the switch still works fine or power adapter is unplugged from the
switch, but the switch still works fine.
KVM Switch unit draws the power source from power adapter and all PC’s PS/2 port. Some PC’s
PS/2 port can support enough power for the switch, but some PC’s PS/2 port (like laptop,
notebook computer…etc.) is unable to supply enough power for the switch. In order to make sure
the system can work steadily, please do not set power switch to off state or remove the power
adapter from the switch.
9. If forgetting the “ password ” you typed, please contact your supplier.
10. The remote mouse doesn’t work or is not synchronous
Make sure the mouse settings in PS/2 IP-KVM switch match the mouse model. There are some
circumstances where the mouse synchronization process could behave incorrectly, refer to
Section 5.4.3 for further explanation.
11. Login on PS/2 IP-KVM switch fails.
Was the correct combination of user and password given? On delivery, the user ” super ” has the
password ”PS/2 IP-KVM switch” depending on the actual device. Moreover your browser must be

configured to accept cookies.
12. The Remote Console window can’t connect to PS/2 IP-KVM switch.
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.
13. No connection can be established to PS/2 IP-KVM switch.
Check whether the network connection is working in general (ping the IP address of PS/2 IP-KVM
switch). If not, check network hardware. Is PS/2 IP-KVM switch powered on? Check whether the
IP address of PS/2 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, PS/2 IP-KVM switch can’t work either.
14. In the browser the PS/2 IP-KVM switch pages are inconsistent or chaotic.
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 PS/2 IP-KVM switch pages
may be loaded from your browser cache and not from the card.
15. Can’t upload the signed certificate in MacOS X
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.
16. 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 boxes”’ enabled in the mouse settings of the operating system. This option needs to be
disabled.
17. Remote Console doesn’t open with Opera in Linux
Some versions of Opera don’t grant enough permission if the signature of the applet can’t be
verified. You can add the lines grant code Base "nn.pp.rc.RemoteConsoleApplet" {permission
java.lang.RuntimePermission "accessClassInPackage.sun.*";};to the java policy file of opera (e.g.
/usr/share/opera/java/opera.policy) to solve the problem.

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).
