2. Introduction  
Thank you for purchasing KVM-0850/1650, PS/2 IP-KVM switch, which can save your MONEY, TIME,  
SPACE, EQUIPMENT and POWER. KVM-0850/1650 defines a new class of remote KVM access  
devices. KVM-0850/1650 combines an 8/16-port KVM switch with digital remote KVM access via IP  
networks and comprehensive system management.  
KVM-0850/1650 provides convenient; remote KVM access and control via LAN or Internet. It captures,  
digitizes, and compresses video signal and transmits with keyboard and mouse signals to and from a  
remote computer. KVM-0850/1650 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.  
KVM-0850/1650 supports consoles consisting of PS/2 style keyboards and mouse, and HD 15 video  
output. KVM-0850/1650 will automatically detect the current video mode of the console, however  
manual fine-tuning is recommended to receive the best video quality. KVM-0850/1650 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  
KVM-0850/1650 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 KVM-0850/1650 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 KVM-0850/1650, administrators can determine which kind of serious hardware failure has  
occurred (See table 2.1).

USB. All the other PCs could support PS/2 only.  
4.1.3.1 KVM-0850/1650 keyboard settings  
The KVM-0850/1650 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 KVM-0850/1650 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 KVM-0850/1650 addresses this situation with an intelligent  
synchronization algorithm. There are two mouse modes available on the KVM-0850/1650.  
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 are not for the Mouse Type of “MS Windows 2000 and  
newer”.  
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 KVM-0850/1650 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 KVM-0850/1650 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 KVM-0850/1650 may not be able to detect them. We recommend using any of  
the standard VESA video modes, instead

5. Usage  
5.1 Prerequisites  
The KVM-0850/1650 features an embedded operating system and applications offering a variety  
of operating 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  
You can full access the device via the embedded web server. The KVM-0850/1650  
environment can be entirely managed using a standard web browser. You can access the  
KVM-0850/1650 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  
KVM-0850/1650's serial port via a terminal mode.  
The primary interface of the KVM-0850/1650 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 or higher.  
In order to access the remote host system using a securely encrypted connection, you need a  
browser that supports the HTTPS protocol, such as IE 6.0. 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.

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.

5.2.2 Hot Plug  
The KVM Switch supports “Hot Plug“ function for easy addition or removal of PCs. The user can  
arrange or maintain PCs as follows:  
a. A PC can be disconnected and reconnected to the same or different port of the KVM unit  
without having to power it off as long as it is not the Daisy-chain port or pass through port.  
b. When the pass through port PC (i.e. The pass through port means the PC port that is  
connected to console port directly) is powered on, for hot plug function, please switch this  
pass through port to next port (or say emulation port ) and then switch back to the pass  
through port.  
c. You may unplug or plug the mouse or the keyboard from the console port any time.  
NOTE  
:
Some O.S. (Operation Systems) like SCO Unix are unable to support “ Hot Plug ” function.  
If you apply “Hot Plug” to this kind of O.S., it will cause unpredictable behavior or shut  
down the PC. Before attempting to use “Hot Plug”, please make sure your O.S. and  
mouse software driver supports the “Hot Plug” function.

5.4 The Remote Console  
General description  
The Remote Console is the redirected screen, keyboard and mouse of the remote host  
system that KVM-0850/1650 controls.  
Figure 5-5. Remote Console  
The Remote Console window is a Java Applet that tries to establish its own TCP connection  
to the KVM-0850/1650. 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.  
If the KVM-0850/1650 is connected to your local network environment and the connection to  
the Internet is via proxy server without configuring NAT, the Remote Console will not be able  
to establish the according connection. The reason is that the web proxies are not capable of  
relaying the RFB protocol.

KVM-0850/1650 IP KVM switch  
If the problems above happen, please consult your network administrator in order to provide  
an appropriate network environment.  
5.5 Main Window  
Clicking the Remote Console opens an additional window. It displays the screen content of  
your host system. The Remote Console will behave exactly the same way as if you were  
sitting directly in front of the 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 slightly delay. The delay depends on the bandwidth of the line,  
which you use to connect to the KVM-0850/1650.  
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 avoid such  
problems by adjusting the keyboard of your remote system to the same mapping as your  
local one.  
The Remote Console window will always try to show the remote screen with its optimal size.  
It will adapt its size to the remote screen. However, you can always resize the Remote  
Console window in your local window system as usual.  
Warning  
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. You can view the state  
of the Remote Console and adjust the local Remote Console settings by clicking the options.  
A description for each options is listed as below:

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 through the HTML-Frontend  
To enable local video port, select this option. This option decides if the local video  
output of KVM-0850/1650 is active and passing through the incoming signal from  
the host system.  
The option Noise Filter defines how KVM-0850/1650 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

• Encoding  
Allows to adjust both compression rate and the colour depth individually. Depending  
on the selected compression rate the data stream between the KVM-0850/1650 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 KVM-0850/1650 simultaneously.  
The standard color depth is 8 Bit (256 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 8 Bit color depth. At lower  
bandwidths only 4 Bit (16 colors) 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 color depth (black/white) should only be used for extremely slow  
network connections.

6.1.2 Telnet Console  
Figure 6-2. Telnet Console  
The KVM-0850/1650 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 KVM-0850/1650 host machine is using a text mode screen resolution.  
Connecting to the KVM-0850/1650 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 KVM-0850/1650. 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 KVM-0850/1650 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.

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.

KVM-0850/1650 IP KVM switch  
Manually  
Allows to adjust both compression rate and the colour depth individually. Depending on  
the selected compression rate the data stream between the KVM-0850/1650 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 KVM-0850/1650 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.

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 KVM-0850/1650.)  
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  
Systems.  
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:  
[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.

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

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  
KVM-0850/1650 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.

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.

6.5.2 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 KVM-0850/1650 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 KVM-0850/1650 connects to a special dynamic DNS server in regular

KVM-0850/1650 IP KVM switch  
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 KVM-0850/1650 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  
KVM-0850/1650.  
You have to perform the following steps in order to enable Dynamic DNS:  
• Make sure that the LAN interface of the KVM-0850/1650 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 KVM-0850/1650 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 KVM-0850/1650 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 KVM-0850/1650 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  
KVM-0850/1650.  
Warning  
The KVM-0850/1650 has its own independent real time clock. Make sure the time  
setting of the KVM-0850/1650 is correct. (See the Section called Date And Time)

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 KVM-0850/1650 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  
KVM-0850/1650 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.

6.5.4 Certificate  
Figure 6-23. Certificate Settings  
The KVM-0850/1650 uses the Secure Socket Layer (SSL) protocol for any encrypted  
network traffic between itself and a connected client. During the connection establishment  
the KVM-0850/1650 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  
KVM-0850/1650 ever produced and certainly will not match the network configuration that  
will be applied to the KVM-0850/1650 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  
KVM-0850/1650 card. In order to do that, the KVM-0850/1650 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  
KVM-0850/1650:  
• 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).  
65

KVM-0850/1650 IP KVM switch  
• Upload the certificate to the KVM-0850/1650 using the “Upload” button as shown in Figure  
6-24.  
Figure 6-24. SSL Certificate Upload  
After completing these three steps, the KVM-0850/1650 has its own certificate that is used  
for identifying the card to its clients.  
Warning  
If you destroy the CSR on the KVM-0850/1650 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 KVM-0850/1650 once it is installed in the user's network  
(usually the fully qualified domain name). It is identical to the name that is used to access  
given here and the actual network name differ, the browser will pop up a security warning  
when the KVM-0850/1650 is accessed using HTTPS.

6.5.5 Serial Port  
Figure 6-25. Serial Port  
The KVM-0850/1650 Serial Settings (Figure 6-25) allow you to specify what device is  
connected to the serial port and how to use it.  
Configuration or console login  
Do not use the serial port for any special function, use it only for the initial configuration  
(see Table 4-1).  
Modem  
The KVM-0850/1650 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 KVM-0850/1650 .  
Logically, connecting to the KVM-0850/1650 using a telephone line means nothing else  
than building up a dedicated point-to-point connection from your console computer to the  
KVM-0850/1650. In other words, the KVM-0850/1650 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 KVM-0850/1650, 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  
KVM-0850/1650 using a modem. The meaning of each parameter will be described  
below. The modem settings are part of the serial settings panel.

KVM-0850/1650 IP KVM switch  
Serial line speed  
The speed the KVM-0850/1650 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 KVM-0850/1650 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 KVM-0850/1650 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  
KVM-0850/1650 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  
KVM-0850/1650 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  
KVM-0850/1650 .

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 KVM-0850/1650 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 KVM-0850/1650 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 KVM-0850/1650. 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 KVM-0850/1650 . To  
show the log list, click on “Event Log” on the “Maintenance” page.  
Since the KVM-0850/1650'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 KVM-0850/1650, all logging  
information is saved permanently and is available after the KVM-0850/1650 has been  
started. If the KVM-0850/1650 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  
KVM-0850/1650 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” ,  
71  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
KVM-0850/1650 IP KVM 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 KVM-0850/1650 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 KVM-0850/1650 device and that needs no  
authentication at all (<serverip>:<port>).  
SNMP Logging enabled  
If this is activated, the KVM-0850/1650 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 KVM-0850/1650, 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.

6.6.3 Update Firmware  
Figure 6-33. Update Firmware  
The KVM-0850/1650 is a complete standalone computer. The software it runs is called the  
firmware. The firmware of the KVM-0850/1650 can be updated remotely in order to install  
new functionality or special features.  
A new firmware update is a binary file, which can be downloaded from our web site at  
http://www.level1.com 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 use WinZip  
program called unzip.  
Before you start updating the firmware of your KVM-0850/1650 the new uncompressed  
firmware file has to be accessible on the system that you use for connecting to the  
KVM-0850/1650.  
Updating the firmware is a three-stage process:  
• Firstly, the new firmware file is uploaded onto the KVM-0850/1650. 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  
KVM-0850/1650 '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  
KVM-0850/1650 manually. Half a minute after the reset, the KVM-0850/1650 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 KVM-0850/1650 's power supply will not be interrupted!

7. Troubleshooting  
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  
z
z
Make sure the keyboard works when directly plugged into the computer.  
Try a different keyboard, but use only 101, 102 or 104-key keyboard.  
7. The Mouse is not detected during PC boot up.  
z
z
Make sure the mouse works when directly plugged into the computer.  
Make sure the mouse is a true PS/2 mouse. A combo mouse will work just as long as it is set for  
PS/2 mode with the correct adapter. Try a different mouse.  
z
Avoiding moving the mouse or pressing the mouse buttons when switching ports or during boot  
up process.  
z
z
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 KVM-0850/1650 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 KVM-0850/1650 fails.  
Was the correct combination of user and password given? On delivery, the user ” super ” has the  
password ”KVM-0850/1650” depending on the actual device. Moreover your browser must be  
configured to accept cookies.  
12. The Remote Console window can’t connect to KVM-0850/1650.  
Possibly a firewall prevents access to the Remote Console. Make sure the TCP port numbers 443  
77  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
KVM-0850/1650 IP KVM switch  
or 80 are open for incoming TCP connection establishments.  
13. No connection can be established to KVM-0850/1650.  
Check whether the network connection is working in general (ping the IP address of  
KVM-0850/1650). If not, check network hardware. Is KVM-0850/1650 powered on? Check  
whether the IP address of KVM-0850/1650 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, KVM-0850/1650 can’t work either.  
14. In the browser the KVM-0850/1650 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 KVM-0850/1650 pages may  
be loaded from your browser cache and not from the card.  
15. Using MacOS X a HTTPS connection fails  
You have to install the KVM-0850/1650 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.  
16. 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.  
17. 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.  
18. 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.
