SERVSWITCH™ SPECTRA
F. If swapping cables doesn’t solve the problem, try
plugging the CPU into the other CPU port on the
Spectra. If the CPU boots when it’s connected to the
other port, one or more of the first port’s connectors
are probably defective.
G. If swapping ports doesn’t solve the problem, try
plugging a known-good keyboard and mouse directly
into the CPU that’s having the problem. If the CPU
boots, the Spectra might be defective; call Black Box.
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 your monitor, keyboard, or mouse; call
Black Box for technical support.

A. Can you do anything from the keyboard? If not, the
keyboard cable has probably come loose. Reconnect it.
