A.
First make sure your ServManager and (if one is involved) your submaster
are plugged in and powered up.
B.
If the ServManager and submaster are ON, check the master’s
configuration. The keyboard or mouse might not be set correctly for that
CPU.
C.
If the configuration is OK, check your cables. Tighten any loose
connections. For PS/2 type equipment, if the keyboard and mouse strands of
either the CPU cable or the MKM cable have been reversed, plug them into
the proper ports.
D.
If you don’t find a cable error, try swapping in different keyboards and/or
mice one at a time. If the problem goes away when you substitute a device, the
old one might have gone bad.
E.
If swapping input devices doesn’t solve the problem, 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 ServManager or submaster. If the CPU boots when
it’s connected to a different port, the old port is probably defective.
G.
If swapping ports doesn’t solve the problem, try plugging a known-good
keyboard and mouse of the proper type directly into the CPU that’s having
the problem. If the CPU boots, the ServManager or submaster might be
defective; call Black Box for technical support.
H.
If the CPU still doesn’t boot, the CPU’s keyboard or mouse port (or other
components) might be defective. (If the CPU’s Power LED doesn’t light, the
fuse on the CPU’s motherboard might be blown.) If you still have them, plug
that CPU’s original monitor, keyboard and mouse into it and try again. If the
CPU does
not
boot with its original equipment, something in the CPU is
defective; call the CPU’s manufacturer. If the CPU
does
boot, there is some
kind of unusual mismatch between that CPU and the shared monitor,
keyboard, or mouse; call Black Box for technical support.
