5.2.9YOUR MOUSE DOESN’T MOVE THE POINTER/CURSOR

A. What type of mouse is it? If it is any other type than those listed as being supported in item A under Section 5.2.6, chances are that the ServSwitch Jr. MP doesn’t support it.

B. The mouse might not be configured properly.

C. The mouse might not have been connected to the Switch when the Switch was powered up. It might also have been disconnected and reconnected after the Switch was powered up.

D. Your mouse must be connected to a the ServSwitch Jr. MP when the CPUs are booted and when mouse applications are run. Try exiting and re-entering your application; if this doesn’t work, issue the Reset command (see Section 4.3.4).

5.2.10YOUR MONITOR DISPLAY IS FUZZY

A. Check the settings of your monitor, especially the sharpness control.

B. If you can’t solve the problem by changing the monitor settings, you might have run cable too far; maximum distance of original Serv cable from any CPU to the ServSwitch Jr. MP is 20 ft. (6.1 m)—or less, if you are using SVGA video or high- resolution Mac video. You might need to upgrade from original Serv cables to coaxial cables that carry the video signal better. See Section 4.1.3 and Appendix B.

5.2.11YOUR VIDEO IS NOT SYNCHRONIZED OR IS THE WRONG COLOR

A. Check the settings of your monitor, especially the sync or color controls.

B. Your monitor might not be capable of synching to the CPU’s video output. Try a lower resolution or frequency or a more powerful or multisync monitor, or, if the problem is only with your Mac CPUs, attach Mac Adapters for ServSwitch (product code KV99MA) to their video ports.

C. If the video problem is not centered on the monitor itself, check the monitor cable and the video strand of the CPU Cable. Tighten any loose connections.

D. If no cable connectors are loose, begin swapping your cables one at a time. If the problem goes away when you substitute a cable, the old cable is probably defective.

E. If swapping cables doesn’t solve the problem, try plugging the CPU into a different CPU port on the ServSwitch Jr. MP. If the problem goes away when the CPU is connected to a different port, the old port is probably defective.
