1. Introduction
Thank you for purchasing the LINDY CPU IP ACCESS SWITCH LITE. This device allows
operators to monitor and access their computers from remote locations. The IP ACCESS
SWITCH LITE connects to the internet, intranet, LAN or WAN using standard CAT5 or higher
cable, then uses a KVM cable to connect a local KVM switch or server.
The IP ACCESS SWITCH LITE combines convenient digital remote KVM access and control
with integrated system management. It captures, digitizes and compresses the video signal and
transmits it alongside the keyboard and mouse signals, to and from a remote computer. The IP
ACCESS SWITCH LITE provides a non-intrusive solution for remote access and control.
Remote access and control software runs on its embedded processors only – so there is no
interference with server operation, or impact on network performance.
The IP ACCESS SWITCH LITE supports PS/2 keyboard/mouse and 15-way VGA type monitor
connections. It automatically detects the video mode of the console and allows manual fine
tuning for improved video quality.
The IP ACCESS SWITCH LITE also features remote mass storage support – the unit connects
via a USB connection to the computer and allows virtual storage devices to be setup on the host
and accessed from the client.

3. Configuration
The CPU IP ACCESS SWITCH LITE’s
communication interfaces are all based on
TCP/IP. The switch comes pre-configured
with the IP configuration detailed here:
Parameter
IP auto configuration
IP-Address
Net-mask
Default-Gateway
Value
DHCP
-
255.255.255.0
none
Note: If the DHCP connection fails on boot-up, the IP ACCESS SWITCH LITE will not have
an IP address.
If this initial configuration does not meet your requirements, the following section describes the
configuration that is necessary to access the IP ACCESS SWITCH LITE for the first time.
3.1 Initial Configuration via a DHCP Server
By default, the IP ACCESS SWITCH LITE 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 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 ACCESS SWITCH LITE. You can find the
MAC address labelled on the bottom of the switch.
Use the setup tool to adjust the values to your needs. The setup tool can be found on the
3.2 Initial Configuration via a Serial Console
The IP ACCESS SWITCH LITE 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

3.4 Keyboard, Mouse and Video configuration
Between the IP ACCESS SWITCH LITE 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.
3.4.1 IP ACCESS SWITCH LITE Keyboard Settings
The IP ACCESS SWITCH LITE 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 IP
ACCESS SWITCH LITE front-end.
3.4.2 Remote Mouse Settings
A common problem with KVM devices is the synchronization between the local and remote
mouse cursors. The IP ACCESS SWITCH LITE addresses this problem with an intelligent
synchronization algorithm. There are two mouse modes available on the IP ACCESS SWITCH
LITE: Auto mouse speed and Fixed mouse speed.
Auto mouse speed
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:
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]
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.
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.
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.

3.4.3 Host System Mouse Settings
The host's operating system obtains various settings from the mouse driver.
Note: The following limitations do not apply when using USB mice and
Windows 2000 and higher!
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
If using Windows XP, disable the enhance pointer precision setting.
Active Desktop
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.
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.
3.4.4 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 IP ACCESS SWITCH LITE 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.

3.4.5 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 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.
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.
3.4.6 Video Modes
The IP ACCESS SWITCH LITE 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 ACCESS SWITCH LITE switch may not be able to detect them.
We recommend using any of the standard VESA video modes instead.

4. Usage
4.1 Prerequisites
The IP ACCESS SWITCH LITE 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.
The following interfaces are supported:
Telnet
A standard Telnet client can be used to access an arbitrary device connected to the IP
ACCESS SWITCH LITE’s serial port via a terminal.
HTTP/HTTPS
Full access is provided by the embedded web server. The IP ACCESS SWITCH LITE switch
environment can be entirely managed using a standard web browser. You can access the IP
ACCESS SWITCH LITE using the insecure HTTP protocol, or using the encrypted HTTPS
protocol. Whenever possible, use HTTPS.
The primary interface of the IP ACCESS SWITCH LITE 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:
For a non-secure connection to the IP ACCESS SWITCH LITE, we recommend the following
browsers:
ƒ Microsoft Internet Explorer version 6.0 or higher
ƒ Netscape Navigator 7.0 or Mozilla 1.6
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.

4.2 Logging In
4.2.1 Login to the IP ACCESS SWITCH LITE
Launch your web browser. Direct it to the address of your IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE switch a symbolic
name in the DNS.
Example: Type the following in the address line of your browser when establishing an
unsecured connection:
When using a secure connection, type in:
This will lead you to the IP ACCESS SWITCH LITE login page as shown below:
The IP ACCESS SWITCH LITE has a built-in super user account that has all the permissions
enabled to administrate your IP ACCESS SWITCH LITE switch:
Login name super (factory default)
Password
pass (factory default)
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.
Please make sure you change the super user password immediately after you have installed
and accessed your IP ACCESS SWITCH LITE 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.

4.3 Navigation
Once logged into the IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE.
Within the main area, task-specific information is displayed.
Return to the main page of the IP ACCESS SWITCH LITE
Logout from the IP ACCESS SWITCH LITE
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.
Access the Remote Console
15
Download from Www.Somanuals.com. All Manuals Search And Download.
The Remote Console is the redirected screen, keyboard and mouse of the remote host system
that the IP ACCESS SWITCH LITE switch controls. Selecting this button opens the Remote
Console Main Window.
The Remote Console window is a Java Applet that establishes its own TCP connection to the IP
ACCESS SWITCH LITE. 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 IP ACCESS SWITCH LITE 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.
4.3.1 Remote Console Main Window
Starting the Remote Console opens an additional window. It displays the screen content of your
host system. The Remote Console will behave in exactly the same way as if you were sitting
directly in front of the screen of your host system. This means that the keyboard and mouse can
be used in the usual way. However, be aware of the fact that the host 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 ACCESS SWITCH LITE.

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.
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.
4.3.2 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.
Ctrl+Alt+Delete
Sends the ‘Control Alt Delete’ key combination to the remote system
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 IP ACCESS SWITCH LITE tries to adjust itself for the best possible video
quality.
Sync mouse
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.
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.
Tip: When in single mouse mode use the hotkey combination [ALT] + [F12] to release
mouse control and access the menus etc.

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

Local Keyboard
Used to change the language mapping of your browser running the Remote Console Applet.
Normally, the applet determines the correct value automatically. However, depending on your
particular KVM and your browser settings this is not always possible. A typical example is a
German localized system that uses a US-English keyboard mapping. In this case you must
manually change the local keyboard setting to the correct language.

5.1.2 Telnet Console
The IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE host is using a text mode screen resolution.
Connecting to the IP ACCESS SWITCH LITE 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 ACCESS SWITCH LITE.
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 IP ACCESS SWITCH LITE 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.

5.2.1 Floppy Disk
Follow the steps below to upload a virtual floppy image to the IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE’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, Linux).
To create a floppy image file copy the contents of a floppy to a file. You can use the following
command:
dd [ if=/dev/fd0 ] [ of=/tmp/floppy.image ]
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.)

5.3.2 Users And Groups
The IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE for the first time.
While the user account never sees the following options, the 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 button
to see the user information.
New User name

5.4 KVM Settings
5.4.1 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.
User select box
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.
Manually
Allows adjustment of both compression rate and colour depth individually. Depending on the
selected compression rate the data stream between the IP ACCESS SWITCH LITE and the
Remote Console will be compressed in order to save bandwidth. Since high compression rates
35
Download from Www.Somanuals.com. All Manuals Search And Download.
are very time consuming, they should not be used when several users are accessing the IP
ACCESS SWITCH LITE 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 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).
Sun Microsystems Java Browser Plugin
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
according 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:
[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 keypresses and releases. The star inserts
a pause with a duration of 100 milliseconds.

5.4.2 Keyboard/Mouse
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.
To enable USB remote keyboard access during the boot process of the host, the following
conditions must be fulfilled:
ƒ the host BIOS must have USB keyboard support
ƒ 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.
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.
38

Mouse Speed
ƒ Auto mouse speed Use this option if the mouse settings on the host use an additional
acceleration setting. The IP ACCESS SWITCH LITE tries to detect the acceleration and
speed of the mouse during the mouse sync process.
ƒ 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 Apply button.
5.4.3 Video
Miscellaneous Video Settings
Noise filter
This option defines how the IP ACCESS SWITCH LITE 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 really changing (depending on the quality of the video input signal). All in
all the default setting should be suitable for most situations.

5.5.2 Dynamic DNS
illustration below)
The IP ACCESS SWITCH LITE 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 ACCESS SWITCH LITE 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.
The administrator has to register an IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE.
You have to perform the following steps in order to enable Dynamic DNS:
ƒ Make sure that the LAN interface of the IP ACCESS SWITCH LITE is properly configured.
ƒ Open the Dynamic DNS Settings configuration dialog

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 tries to make 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.

5.5.4 Certificate
The IP ACCESS SWITCH LITE uses the Secure Socket Layer (SSL) protocol for any encrypted
network traffic between itself and a connected client. During the connection establishment the
IP ACCESS SWITCH LITE has to expose its identity to a client using a cryptographic certificate.
This certificate and the underlying secret key is the same for all IP ACCESS SWITCH LITE units
and certainly will not match the network configuration that will be applied to the IP ACCESS
SWITCH LITE 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
ACCESS SWITCH LITE. In order to do this, the IP ACCESS SWITCH LITE 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.
The following steps are necessary to create and install an SSL certificate for the IP ACCESS
SWITCH LITE:
1. Create an SSL Certificate Signing Request using the panel shown in the screen shot
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
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 IP ACCESS SWITCH LITE switch using the Upload button.

After completing these three steps, the IP ACCESS SWITCH LITE has its own certificate that is
used to identify it to its clients.
Note: If you destroy the CSR on the IP ACCESS SWITCH LITE 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.

serial interface of the IP ACCESS SWITCH LITE.
Connecting to the IP ACCESS SWITCH LITE using a telephone line allows you to set up a
dedicated point-to-point connection from your console computer to the IP ACCESS SWITCH
LITE. In other words, the IP ACCESS SWITCH LITE 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 ACCESS SWITCH LITE, 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 IP ACCESS SWITCH
LITE using a modem. The meaning of each parameter will be described below. The modem
settings are part of the serial settings panel.
ƒ Serial line speed
The speed the IP ACCESS SWITCH LITE 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.

ƒ Modem Init String
The initialization string used by the IP ACCESS SWITCH LITE 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.
ƒ Modem server IP address
This IP address will be assigned to the IP ACCESS SWITCH LITE 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 ACCESS SWITCH
LITE and your console computer. The default value will work in most cases.
ƒ 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 ACCESS SWITCH LITE 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 ACCESS
SWITCH LITE.

5.5.6 Date And Time
Here you can set the internal real-time clock of the IP ACCESS SWITCH LITE. You can adjust
the clock manually or use an NTP timeserver. Without a timeserver your time setting will be lost
if the IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE 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.

5.5.7 Event Log
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 IP ACCESS SWITCH LITE.
To show the log list, click on Event Log on the Maintenance page.
Since the IP ACCESS SWITCH LITE’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 IP ACCESS SWITCH
LITE all logging information is saved permanently and is available after the IP ACCESS
SWITCH LITE has been started. If the IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE 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.

SMTP Logging enabled
With this option, the IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE and that needs no authentication at all
(<serverip>:<port>).
SNMP Logging enabled
If this is activated, the IP ACCESS SWITCH LITE 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 IP ACCESS SWITCH LITE, 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.

called the firmware. The firmware of the IP ACCESS SWITCH LITE can be updated remotely in
order to install new functionality or special features.
54
Download from Www.Somanuals.com. All Manuals Search And Download.
A new firmware update is a binary file which can be sent to you by email or which you can
Updating the firmware is a three-stage process:
1. The new firmware file is uploaded to the IP ACCESS SWITCH LITE. 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.
Note: This process is not reversible and may take some minutes. Make sure the IP ACCESS
SWITCH LITE’s power supply will not be interrupted during the update process.
3. After the firmware has been stored, the panel will request you to reset the IP ACCESS
SWITCH LITE manually. Half a minute after the reset the IP ACCESS SWITCH LITE will run
with the new firmware version and should be accessible. However, you will be required to
login once again.
Note: The three-stage 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. Make sure the IP
ACCESS SWITCH LITE’s power supply will not be interrupted during the update process!

5.6.4 Unit Reset
This section allows you to reset specific parts of the device. This involves the keyboard and
mouse, the video engine and the IP ACCESS SWITCH LITE itself.
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.
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 IP
ACCESS SWITCH LITE functionality, click on the Reset button.
Note: Only the super user is allowed to reset the IP ACCESS SWITCH LITE.

super and the password is pass. Furthermore, your browser must be configured to accept
cookies.
Q 004: The Remote Console window can’t connect to the IP ACCESS SWITCH LITE.
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 connections. Install the latest version of Java
Virtual Machine,
Q 005: No connection can be established to the IP ACCESS SWITCH LITE.
A 005: Check whether the network connection is working in general (ping the IP address of IP
ACCESS SWITCH LITE). If not, check the network hardware. Is the IP ACCESS SWITCH LITE
powered on? Check whether the IP address of IP ACCESS SWITCH LITE 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.
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 ACCESS SWITCH LITE switch pages are inconsistent.
A 007: Check your browser cache settings. Especially make sure that the cache settings are not
set to something like ‘never check for newer pages’. Otherwise the IP ACCESS SWITCH LITE
pages may be loaded from your browser cache and not from the unit.
Q 008: Windows XP doesn’t awake from standby mode
A 008: This could be a Windows XP problem. Try not to move the mouse while XP goes into
standby mode.
