2- AND 4-PORT SERVSWITCH DT PRO II  
2. Overview  
2.1 Introduction  
The 2- or 4-Port ServSwitch DT Pro II KVM Switch is the most comprehensive  
desktop switch to date. It’s flexible: Use it to connect a PS/2 keyboard, video, and  
mouse to PS/2 CPUs, USB KVM to PS/2 CPUs, PS/2 KVM to USB CPUs, or USB  
®
®
KVM to USB CPUs. Supported mice include Microsoft IntelliMouse and other  
mice, and the ServSwitch unit’s USB ports comply with USB 2.0 requirements.  
Plus, you can connect audio and USB 2.0 peripherals to the KVM switch.  
Using a hotkey command sequence (see Section 4.3), you can asynchronously  
switch the KVM control and the USB devices. And the ServSwitch works with  
®
common operating systems, including Windows 98/Me/2000/XP, Windows NT ,  
®
Linux, Novell NetWare, and Mac OS.  
Setup is fast and simple, and there’s no software to configure. Its small desktop  
footprint is ideal for on or under your desktop. Use either front-panel buttons on  
the ServSwitch or hotkeys (which are key sequences on your keyboard) to select  
ports or start AutoScan. The front-panel buttons include integral LEDs. The LED  
will light with the corresponding active port when manually switching between the  
computers. The ServSwitch beeps to confirm that it’s in hotkey mode. The  
AutoScan function enables you to automatically scan and monitor all computers,  
one by one, that are connected to the ServSwitch.

3. Installation  
3.1 ServSwitch Placement  
The 2- or 4-Port ServSwitch DT Pro II KVM Switch is small, portable, and designed  
to fit on a desktop. Consider the following when deciding where to place the KVM  
switch:  
• How long are the cables attached to your keyboard, mouse, and monitor?  
• How far away are the computers from the console?  
• How long are the cables you use to connect your computers to the ServSwitch?  
CAUTION  
Do not place cables near machines that create electrical noise such as  
fluorescent lighting, air conditioning equipment, etc.  
3.2 Hardware Installation  
This section provides instructions for the basic hardware setup of a single  
ServSwitch.  
CAUTION  
Before you begin, make sure that power to all the devices that you will  
be connecting is turned off.  
To prevent damage caused by ground potential differences, make sure  
that all devices are properly grounded. If you don’t follow these  
instructions, your computers and/or the ServSwitch could be damaged.  
3.2.1 CONNECTING THE CONSOLE  
1. Power off all computers.  
2. Connect your USB keyboard and USB mouse or PS/2 keyboard and PS/2  
mouse directly to the USB or PS/2 keyboard and mouse ports (labeled with  
keyboard and mouse symbols) on the front of the ServSwitch. USB  
connections are shown in Figure 3-1.
