SERVSWITCH™ BRAND PS/2 MICRO EXTENDER
7. Troubleshooting
7.1 Common Problems
This section discusses difficulties that people sometimes have with the ServSwitch™
Brand CAT5 PS/2 Micro Extender, and suggests possible remedies. If the
recommended actions don’t help, try rebooting the PC. If all else fails, or if you
don’t see your problem here, or if your problem keeps recurring, call Black Box
Technical Support as directed in
Section 7.3 .

EYBOARD
The PC boots correctly with no error messages but the keyboard does not work at all.
1. Check the keyboard cable and (if necessary) the PS/2 keyboard-extension
cable going to the CPU; if either of them are loose, or if you have the
keyboard and mouse cables reversed (plugged into each other’s Extender
ports), plug the cable(s) in properly and cycle power to the Remote Unit.
2. Check the interconnect cable between the Extender’s Local and Remote
Units. Is it intact along its length and securely connected at both ends? And is
it wired correctly? (Compare its wiring with that shown in the
Appendix .)
3. If the PC is a Pentium ® class machine, see the entry for the “My Pentium class
PC...” problem in Section 7.1.3 .
4. Try a different model of keyboard. If the new keyboard works, the original
one might be incompatible (some older autosensing keyboards don’t work
with the Extender).
When I press keys on my keyboard the wrong characters appear.
Cycle power to the Remote Unit. If this doesn’t work, reboot the PC.
The PC always comes up with “Keyboard Error.”
1. If the system appears to work fine after you press [F1] or [ESC], adjust your
BIOS setup so that the PC doesn’t test the keyboard.
2. If the PC is a Pentium class machine, see the entry for the “My Pentium class
PC...” problem in Section 7.1.3 .
