2. Overview
!
!
2.1 Introduction
!
The 4-Port ServSwitch USB/DVI/Audio KVM Switch allows you to control up to
four computers from a single IBM® console (USB keyboard, USB mouse, and DVI
[Digital Visual Interface] monitor, plus audio). Supported mice include Microsoft®
IntelliMouse® and other mice.
!
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 front-panel buttons on the
ServSwitch to select ports or start AutoScan. The front-panel LEDs will light with
the corresponding active port when switching between the computers. The
AutoScan function allows you to automatically scan and monitor all computers,
one by one, that are connected to the ServSwitch.

The 4-Port ServSwitch DT Series USB/DVI/Audio 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.
