7. The ServSwitch Multi Hub

7.1 Overview

The ServSwitch Multi Hub is designed to make configuring and installing large, complex cascaded ServSwitch
Multi systems as efficient and economical as possible. By channeling the expansion signals that pass between
other ServSwitch Multi units through a “central switching station,” the Hub streamlines your configuration and
can greatly reduce the number of ServSwitch Multi units, Expansion Transmit and Receive Cards, and
expansion cables in the system.
Figure 7-1 shows a simple 16 x 16 matrix of 4-User units configured with and without the Hub. All users in
this system can access any computer at any time.

Using only ServSwitch
Multi EXP units, connecting
16 users to 16 computers
so that all of the users have
independent access to all
of the computers requires
eight EXPs, 32 CAT5
Transmit Cards, 32 CAT5
Receive Cards, and
128 CAT5 expansion
cables. In this picture, each
of the lines between the
EXP units represents eight
cables.
If you use a Hub with one
Transmit Module and one
Receive Module installed,
you’ll still need eight EXP
units, but only eight CAT5
Transmit Cards, eight CAT5
Receive Cards, and
64 expansion cables—
a significant savings. In this
picture, each line between
the EXP units and the Hub
represents four cables.
