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.

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.
