6.2 Determining Where to Install Cards and Attach Equipment
Once you’ve chosen the best placements and system configuration for your ServSwitch Multis, you’ll need to
determine (a) which Expansion Cards to install in which Switches, (b) where to put your computers and user
equipment (which will determine where you install your CPU and User-Interface Cards), and (c) where to put
your terminals, routers, etc. if you’re connecting any to the system (which will determine where you install your
Management and Serial Control Cards).
As you plan, here’s what you need to keep in mind about how the Expansion Cards work:
1. In order for a computer attached to a ServSwitch Multi to transmit its video signal to consoles attached to
other Switches in the system, you must install at least one Transmit Card in the computer’s Switch. Refer to
Figure 6-5.
2. In order for a console attached to a ServSwitch Multi to receive signals from computers attached to other
Switches in the system, you must install at least one Receive Card in the console’s Switch. Refer to
Figure 6-5.

In this example, users on Switch 2 have
access to the local computers (the ones
attached to their own Switch) only, because
there is no Receive Card installed in Switch 2.
Users on Switch 1 can not only access the
local computers, they can also access the
computers attached to Switch 2, because a
Transmit Card is installed in Switch 2 and a
Receive Card is installed in Switch 1. But they
cannot reach the computers on Switch 0
because no Transmit Card is installed in
Switch 0.
Users on Switch 0 have access to all
computers in the system—the local computers
plus the computers on Switches 1 and 2—
because the Transmit Cards installed in
Switches 1 and 2 are connected (directly in
Switch 1’s case, indirectly in Switch 2’s) to the
Receive Card installed in Switch 0.
