OUSE
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.
doesn't support it.
B. The mouse might not be configured properly.
C. Your mouse must be connected to the ServSwitch Jr. 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).

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. is 20 ft. (6.1 m)—or less, if you are using SVGA 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.

OUR
IDEO IS
A. If you are trying to use an IBM 9515, 9517, or 9518 monitor, you need special
cables to carry the video correctly. Call Black Box for technical support.
B. Check the settings of your monitor, especially the sync or color controls.
C. Your monitor might not be capable of synching to the selected video resolution
or frequency (refresh rate). Try a lower resolution or frequency or a more
powerful monitor.
D. If the video problem is not centered on the monitor itself, check the monitor
cable and the video strand of the CPU Adapter Cable. Tighten any loose connections.
E. 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.
F. If swapping cables doesn't solve the problem, try plugging the CPU into a
different CPU port on the ServSwitch Jr. If the problem goes away when the CPU is
connected to a different port, the old port is probably defective.
