Use a terminal software (e.g. hyper term or minicom) to connect to PS/2 IP-KVM switch. Reset PS/2 IP-KVM switch and immediately press <ESC>. You will see some device information and a ’=>’ prompt. Enter the command ’config’ and press <Enter>. After waiting a few moments you may configure IP auto configuration, IP address, net mask and default gateway. Pressing <Enter> without entering values does not change settings. The gateway value must be set to 0.0.0.0 (for no gateway) or any other value. You will be asked if the values are correct and get a chance to correct them. After confirming, PS/2 IP-KVM switch performs a reset.

2.Use a crossover Ethernet cable to connect PS/2 IP-KVM switch to a subnet where a DHCP server is available. After the DHCP server has assigned an IP address to PS/2 IP-KVM switch you can use the web interface to configure the device.

Web interface

IP-KVM switch may be accessed using a standard JAVA enabled web browser. You may use the HTTP protocol or a secure encrypted connection via HTTPS. Just enter the configured IP address of

IP-KVM switch into your web browser.

Login name	super (factory default)
Password	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).

4. Configuration
4.1 Initial Configuration
The PS/2 IP-KVM switch's communication		interfaces are all based on TCP/IP. It comes
pre-configured with the IP configuration listed in Table 4-1.
	Parameter		Value
	IP auto configuration		DHCP
	IP-Address		-
	Net-mask		255.255.255.0
	Default-Gateway		none

Table 4-1. Initial network configuration

Warning

If the DHCP connection fails on boot up, the PS/2 IP-KVM switch will not have an IP address.

If this initial configuration does not meet your requirements, the following describes the initial IP configuration that is necessary to access the PS/2 IP-KVM switch for the first time.

4.1.1 Initial configuration via DHCP server

By default, the PS/2 IP-KVM switch will try to contact a DHCP server in the subnet to which it is physically connected. If a DHCP server is found, it may provide a valid IP address, gateway address and net mask. Before you connect the device to your local subnet, be sure to complete the corresponding configuration of your DHCP server. It is recommended to configure a fixed IP assignment to the MAC address of the PS/2 IP-KVM switch. You can find the MAC address labeled on the bottom side.

If this initial configuration does not meet your local requirements, use the setup tool to adjust the values to your needs. The setup tool can be found on the CD ROM delivered with this package.

You can follow the procedure described below.

PS/2 IP-KVM switch Setup Tool

MAC Address Detection

Connect the IP-KVM switch to your computer either via local network, or via USB. Start the setup tool from the CD ROM on the computer that the IP-KVM switch is installed. Depending on the connection (USB or network), the device detection is different. A window opens as seen below:

14

On the upper left corner, the MAC address of the IP-KVM switch is displayed. To detect the MAC address, manually, press the button “Refresh Devices”. The displayed MAC address is the same MAC address printed on the white sticker placed on the back of the IP-KVM switch. If the IP-KVM switch is connected via USB, it is classified as an USB device and an appropriate drive letter is chosen for this device.

On the lower right corner of the window, there are two buttons: “Query Device” and “Setup Device”. Press the “Query Device” button to display the preconfigured values of the network configuration. The values are displayed in the text fields located above. If necessary, adjust the network settings to your needs. To save the changes enter an user name and an according password. Then press the “ Setup Device “ button.

Authentication

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

Super user login

Enter the login name of the super user. The initial value is “ super ”. All of characters are lower case.

Super user password

Enter the current password for the super user. This initial value is “ pass “. All of characters are lower case.

New super user password

Enter the new password for the super user.

New password (confirm)

Re-type the new password for the super user.

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

8/16 PS/2 KVM over IP switch

4.1.2 Initial configuration via serial console

Using a serial terminal, the PS/2 IP-KVM switch has a serial line interface (rear side). This connector is compliant with the RS 232 serial line standard. The serial line has to be configured with the parameters given in Table 4-2.

When configuring with a serial terminal, reset the PS/2 IP-KVM switch and immediately press the “ESC” key. You will see some device information, and a “=>” prompt. Enter “config”, press “Enter” and wait for a few seconds for the configuration questions to appear.

Parameter	Value
Bits/second	115200
Data bits	8
Parity	No
Stop bits	1
Flow Control	None

Table 4-2. Serial line parameters

As you proceed, the following questions will appear on the screen. To accept the default values which are shown in square brackets below, press “Enter”.

IP auto configuration (non/dhcp/bootp) [dhcp]:

IP [192.168.1.22]:

Net mask [255.255.255.0]:

Gateway (0.0.0.0 for none) [0.0.0.0]:

IP autoconfiguration

With this option, you can specify whether the PS/2 IP-KVM switch should get its network settings from a DHCP or BOOTP server. For DHCP, enter “dhcp“, and for BOOTP enter “bootp“. If you do not specify any of these, the IP autoconfiguration is disabled and subsequently you will be asked for the following network settings.

IP address

The IP address the PS/2 IP-KVM switch uses. This option is only available if IP autoconfiguration is disabled.

Net mask

The net mask of the connected IP subnet. This option is only available if IP autoconfiguration is disabled.

Gateway address

The IP address of the default router for the connected IP subnet. If you do not have a default router, enter 0.0.0.0. This option is only available if IP autoconfiguration is disabled.

4.1.3 Keyboard, Mouse and Video configuration

Between the PS/2 IP-KVM switch and the host, there are two interfaces available for transmitting keyboard and mouse data: USB and PS/2. The correct operation of the remote mouse depends on several settings, which will be discussed in the following subsections.

16

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
