INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
Class B Digital Device. This equipment has been tested and found to comply with
the limits for a Class B computing device pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation. This equipment generates,
uses, and can radiate radio frequency energy, and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. If this equipment does cause harmful interference to radio or
telephone reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult an experienced radio/TV technician for help.
CAUTION
Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate
the equipment.
To meet FCC requirements, shielded cables and power cords are required to
connect this device to a personal computer or other Class B certified device.
This digital apparatus does not exceed the Class B limits for radio noise emission from digital
apparatus set out in the Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de classe B prescrites dans le Règlement sur le brouillage

2. Overview
2.1 Introduction
The 4-, 8-, and 16-Port ServSwitch™ EC Series IP KVM Switches allow you to use
the Internet or your TCP/IP enabled network to remotely monitor and control
critical PC servers and workstations using an industry-standard Web browser or
VNC client. Or, use On-Screen Display (OSD) or hotkeys to manage the switch.
The ServSwitch supports industry-standard networking and management protocols
such as TCP/IP and SNMP. It offers secure management options including SSL
encryption, SSH tunneling, and RADIUS. The ServSwitch is platform-independent
and can be managed using any Java™ enabled Web browser.

CHAPTER 3: Installation
3. Installation
3.1 Quick Start Guide
This quick start guide describes three different ways to quickly set up your
ServSwitch.
Before doing the initial setting:
1. Record your original computer settings, such as TCP/IP, in case you would
like to use this computer for other tasks.
2. Make sure you have the latest Java software downloaded from
http://www.java.com.
3. Disable mouse acceleration on the host computer(s) and client computer.
See Section 3.2 for details.
Hardware you will need for the quick start guide is listed below:
• (1) 4-, 8-, or 16-Port ServSwitch EC Series IP KVM Switch
• (1) hub with power adapter
• (1) computer with a keyboard, mouse, and monitor
• (2) CAT5 cables with RJ-45 connectors
• (1) DB9 RS-232 null-modem cable (included)

12
4-, 8-, AND 16-PORT SERVSWITCH EC SERIES IP KVM SWITCH
T HE F IRST W AY :I F YOU DON ’ T HAVE DHCP (D YNAMIC H OST C ONFIGURATION P ROTOCOL )
1. Connect the CAT5 cable to the LAN port on the ServSwitch unit’s back panel.
Connect the opposite end of the cable to the hub.
2. Using the second CAT5 cable, connect the hub to the computer. See Figure
3-1.
Figure 3-1. Setting up the ServSwitch without DHCP.
3. Set the IP address of a computer connected on the same network as the
ServSwitch to a similar unused address such as 192.168.1.124 and the subnet
mask of 255.255.255.0.
For a Windows®XP environment
4. Click on Start, then right-click on My Network Places. Figure 3-2 appears.

6. Double-click on Internet Protocol (TCP/IP). See Figure 3-4.
Figure 3-4. Local Area Connection, Properties, General tab screen.
7. Click on Advanced in Figure 3-4, then click Add to add the IP address
192.168.1.124 and the subnet mask 255.255.255.0 in Figure 3-5.

T HE SECOND WAY : IF YOU HAVE DHCP (D YNAMIC H OST C ONFIGURATION P ROTOCOL )
1. Write down the ServSwitch unit’s MAC address (it’s located on a white sticker
on the bottom of the ServSwitch). An example of a MAC address is 00-0E-CS-
00-00-1A.
2. Power on the ServSwitch and connect it to the network via its LAN port on
the back panel. The DHCP will automatically assign an IP address for the
ServSwitch.

16
4-, 8-, AND 16-PORT SERVSWITCH EC SERIES IP KVM SWITCH
3. Access the DHCP log from your file server. A simple DHCP log looks similar
to the one shown in Figure 3-6.
Figure 3-6. DHCP log.
4. From the DHCP log shown in Figure 3-6, find the DHCP that’s assigned an IP
to the ServSwitch (192.168.22.4). Once you locate this address, do NOT
power off the ServSwitch unit’s server since it might lease a different IP
address.
5. Open a Web browser, and type https://192.168.22.4 to access the
ServSwitch. Figure 3-7 appears.
NOTE
Remember to type safter http. (You will see a lock icon on the lower
right corner of your screen. This means that all your information is
protected by 128-bit SSL encryption.)

6. Type admin for both username and password, then click on the Login
button.
T HE THIRD WAY : USING THE H YPER T ERMINAL VIA A S ERIAL P ORT
1. Connect the DB9 RS-232 null-modem serial cable (included) to the serial
port on the ServSwitch unit’s rear panel. Connect the opposite end of the
cable to the computer’s serial port (COM1, COM2,…). See Figure 3-8.
Figure 3-8. Connecting a computer to the ServSwitch unit’s serial port.
2. From your computer’s Administration screen in Windows XP, select All
Programs, Accessories, Communications, and HyperTerminal. See Figure 3-9.
