CHAPTER 2: Introduction

All cable connections are made at the rear panel of the ServSwitch, as
illustrated in Figures 2-4 and 2-5 and described below.

Panel Label Conn. Description
Connect your computers to these ports with “CPU
Adapter Cables.” At the ServSwitch end these cables
have a DB25 male connector; at the other ends, they
have appropriate connectors to plug into your CPUs’
video, keyboard, and mouse ports. These cables take
the signals that would normally pass between the
CPUs’ ports and the monitor, keyboard, and mouse,
and carry them between the CPUs’ ports and the
Switch instead.
You could also connect “submaster” Serv type
switches to these ports using “ServSwitch-to-
ServSwitch Expansion Cables.” These cables have
DB25 male connectors at both ends; at the submaster
end, they should be plugged into a MONITOR/
KEYBOARD/MOUSE port. Refer to Sections 2.5 and
3.2.4.
