4. Installing CPU-Interface Cards,
Server Cables, and Computers
IMPORTANT NOTE
If you are installing a cascaded ServSwitch Multi system, you should make sure your
Expansion Cards and Cables are installed properly before you begin installing other
types of Cards or attaching devices to the system. Refer to
Chapter 6
and (if your
cascaded system includes any ServSwitch Multi Hubs)
Chapter 7
.
Before you can connect your computers to your ServSwitch Multi system, you will need to configure and install
Autosensing CPU-Interface Cards (our product code KV2000C) for each computer. These Cards have a set of
jumpers that determine the type of video input from the computer (see
Section 4.1
) and an eight-position DIP
switch that determines three other things: how the ServSwitch Multi handles the video signal and sync from that
computer (see
Section 4.2.1
), how long that computer’s inactivity timeout is (see
Section 4.2.2
), and how the
Switch maps certain keyboard keys if the computer is a Macintosh model (see
Section 4.2.3
).
4.1 Setting the Jumpers to Configure the Video-Output Type
If you hold an Autosensing CPU-Interface Card so that its HD44 connector is to the right, as shown in
Figure 4-1, you will see a block of six jumpers labeled “JP1” through “JP6” in the lower right-hand corner of the
Card’s circuit board. The settings of these jumpers determine what basic type of video signals the ServSwitch
Multi should expect from the attached computer. The factory-default setting is for VGA/SVGA video. If the
computer you’ll be attaching to any given CPU-Interface Card always outputs VGA/SVGA video, you don’t
need to change the jumper settings for that Card.

Figure 4-1. The CPU-Interface Card’s video jumpers.
Refer to the configuration diagrams in Figure 4-2 on the next page for all of the possible settings of these
jumpers. On each Card, set the jumpers appropriately for the computer you will be attaching, then add this
information to the Card’s record in the System-Configuration Chart (see
Appendix A
). You might want to
consult the manual(s) for your computers, video cards, and/or monitor to make sure which of the possible
settings is the best for any given computer in your system.
