CHAPTER 8: Troubleshooting

8. Troubleshooting

8.1 Common Problems

This section discusses difficulties that people sometimes have with the ServSwitch™

Brand CAT5 KVM and KVM/Serial/Audio Micro Extenders, and suggests possible

remedies. If the recommended actions don’t help, or if you don’t see your

problem here, or if your

problem keeps recurring, call Black Box Technical Support

as directed in Section 8.3.

8.1.1 K

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 keyboard portion of the

extension cabling to your CPU or KVM switch; if it’s loose, or if you have the

keyboard and mouse cables reversed (plugged into each other’s Micro

Extender ports), plug the cable(s) in properly and reset the keyboard and

mouse as described in Section 7.3.1.

2. Check the interconnect cable between the Micro 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

Appendix A.)

3. If the PC is a Pentium

class machine, see the entry for the “Pentium class

PC...” problem in Section 8.1.3.

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 Micro Extender).

When I press keys on my keyboard the wrong characters appear.

1. Your keyboard might be in the wrong mode. Reset the keyboard and mouse

as described in Section 7.3.1.

2. Power down and reboot the entire system.

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 “Pentium class

PC...” problem in Section 8.1.3.
