SERVSWITCH™

6.2 Common Problems

6.2.1A CPU CONNECTED TO YOUR SERVSWITCH OR A SUBMASTER DOESNT BOOT, AND YOU

GET A KEYBOARD OR MOUSE ERROR

A. First make sure your ServSwitch and (if one is involved) your submaster are plugged in and powered up.

B. If the Switch and submaster are ON, check the master’s configuration. The keyboard and mouse settings for that CPU might not be correct.

C. If the configuration is OK, check your cables. Tighten any loose connections. 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 ServSwitch. 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 directly into the CPU that’s having the problem. If the CPU boots, the ServSwitch or submaster 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 the shared monitor, keyboard, or mouse; call Black Box for technical support.
