SERVSWITCH™ PROFESSOR
Your mouse doesn’t move the pointer/cursor.
A.
What type of mouse is it? If it is any IBM PC type other than those listed as being
supported in item A under the “Your mouse driver doesn’t load” problem, chances
are that the ServSwitch Professor doesn’t support it.
B.
The mouse might not be configured properly.
C.
Your mouse must be connected to a powered ServSwitch Professor when the
attached CPU is booted and when applications that use the mouse are run. Try
exiting and re-entering your application; if this doesn’t work, issue the Reset
command (see
Section 4.3.24
).
Your 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. Total length of bus cable in your system should not be more than
250 ft. (76.2 m); total length of original CPU and User Cables between any station
and a CPU or monitor should not be more than 5 ft. (1.5 m); total length of
coaxial CPU and User Cables should not be more than 20 ft. (6.1 m) unless your
CPUs can drive keyboard and mouse signals strongly enough. If you are already
using coax CPU and User Cables, you might need to add Station Extenders or
CAT5 KVM Extenders; call Black Box for technical support. See
Section 4.1.3
and
Appendix B
.
Your 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 selected video resolution
or frequency (refresh rate). Try a lower resolution or frequency or a more
powerful monitor.
C.
If the video problem is not centered on the monitor, check the video strands of
your cables. 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 ServSwitch Professor. If the problem goes away when the CPU is
connected to a different Professor, the unit you were using is probably defective.
