Chapter 1: Product Overview
Features and Benefits
The ServerLink IP adds economical remote access capability to a PS/2 server or existing
KVM switch. Using industry standard TCP/IP connectivity, this KVM over IP remote access
device provides BIOS level access to a PS/2 server via standard IP connection. The
ServerLink IP can easily integrate with a KVM switch to offer convenient IP-based access
and control to your IT environment. With the secure browser-based access of ServerLink
IP, you can control your servers anywhere, anytime. You can even remotely boot your
business-critical servers from any location.
Security
For enhanced security, 128 bit encryption ensures secure remote connections via industry
standard Secure Sockets Layer (SSL) connectivity. ServerLink IP also eases configuration
complexities. Unlike software remote access solutions, ServerLink IP does not require
agents for each host server.
FLASH upgradeable
The ServerLink IP is FLASH upgradeable for fast and easy updates via the ServerLink web
site.
System log
A system log enables you to track user login and logout, file access, critical events and
other activities. Log files can be saved, printed and emailed.
The ServerLink IP unit
The ServerLink IP provides secure control and management of the host computer through
a web interface and client computer. The ServerLink IP supports a PS/2 keyboard and
mouse on the local console and a USB keyboard and mouse for the host system. The
ServerLink IP does not require any host video drivers. Figure 1.1 shows a typical
ServerLink IP configuration.

Safety Precautions
To avoid potential video and/or keyboard problems when using ServerLink products:
•If the building has 3-phase AC power, ensure that the server and monitor are on the
same phase. For best results, they should be on the same circuit.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe
the following precautions:
•Do not use a 2-wire extension cord in any ServerLink product configuration.
•Test AC outlets at the server and monitor for proper polarity and grounding.
•Use only with grounded outlets at both the server and monitor. When using a backup
Uninterruptible Power Supply (UPS), power the server, the monitor and the
ServerLink IP off the supply.

SL-1000 www.serverlink.com.au
Setting the IP Address
This section provides instructions for setting the IP address for the ServerLink IP.
Using the static IP address
The ServerLink IP boots to the following default static IP address, gateway and netmask:
•IP address: 192.168.0.254
•Gateway: 192.168.0.1
•Netmask: 255.255.255.0
You can use the ServerLink IP on a subnet that matches the default static IP address or
use the ServerLink IP Web Server Network window to change the IP address. For
information on changing the IP address, see Modifying the Configuration in Chapter 4.
Using ARP to Set the IP Address
You can use Address Resolution Protocol (ARP), a command line utility included with most
operating system platforms, to set the IP address for the ServerLink IP. Follow these
instructions to set the IP address using ARP.
NOTE: As a security feature, ARP only runs when the system boots to the default IP
address of 192.168.0.254. Once ARP has been used to move the appliance from this
address, ARP is turned off. The only way to get ARP to run again is to set the IP address to
the default and reboot the system.
To run ARP and set the IP address:
1. Contact your network administrator and obtain an IP address.
2. From a client computer attached to the same subnet as the ServerLink IP, open a
DOS window and enter the following command: arp -s <ip address> <mac address>
Replace <ip address> with the IP address obtained from your network
administrator, and <mac address> with the 12 digit MAC address listed on the
ServerLink IP (for example, 00-05-C2-1E-40-20).
3. Ping the ServerLink IP by entering the following command: Ping <IP Address>
NOTE: During verification of the IP address, the message host not responding may display.
If this message displays four times, the IP or MAC address is incorrect.
4. If the Ping command was successful, remove the IP address from the ARP table
using the following command: arp -d <IP Address>
-or-
If the Ping command failed, verify the IP and MAC address and resolve any communication
issues.

Using DHCP to Obtain the IP Address
If Dynamic Host Configuration Protocol (DHCP) services are available on the local subnet
where the ServerLink IP is installed, use the following instructions to configure the
ServerLink IP to use DHCP to automatically obtain the IP address.
To use DHCP to obtain the IP address:
1. In the web browser Address bar of a client computer, enter the IP address of the
ServerLink IP and click Enter.
2. In the Enter Network Password dialog box, type Admin (default username) and
password (default password) and click OK.
Figure 2.6: Enter Network Password Dialog Box
3. From the Global Settings window, under Category, click Network.
4. From the Network window, select the Use DHCP option and click Apply.
5. The ServerLink IP will automatically obtain an IP address from DHCP services and
use it as the ServerLink IP address. The previous IP address is stored until the Set
Static IP option is enabled.

password (default password) and click OK.
3. From the Global Settings window, under Category, click Network.
4. Select the Set Static IP option and use the previous IP address, gateway and subnet
mask settings, or enter new IP address information and click Apply.
5. Log in to the static IP address and the ServerLink IP Web Server will refresh with the
new IP address.
