CHAPTER 8: Troubleshooting

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.

You can’t switch ports from the keyboard.

A. Can you do anything from the keyboard? If not, the keyboard connector of your User Cable has probably come loose. Reconnect it.

B. Are you trying to reach a computer on a remote Matrix ServSwitch? The port might be busy; try again later. If repeated attempts are unsuccessful, make sure that the Expansion Cables running to that Switch haven’t come loose and that the Switch itself hasn’t been powered down.

C. The Matrix ServSwitch might have lost power for less than three seconds. (This can cause the keyboard to lock up.) Disconnect the keyboard and plug it back in.

D. The keyboard mode that the currently selected CPU port is set for might not match the mode that the CPU on that port expects. Go into the Configuration Menu and change the keyboard-mode setting for the CPU (see Section 4.3).

Sometimes this situation can confuse the CPU or keyboard so badly that it is necessary to reboot the CPU or to reset the keyboard by unplugging it and plugging it back in.

E. For PS/2 type equipment, if the keyboard and mouse connectors of either the CPU Cable or the User Cable have been reversed, plug them into the proper ports.

F. You might be using the keyboard incorrectly. Make sure to use the left Control key to start port-switching commands. Make sure to use the numeric keys at the top of the keyboard rather than the numeric keypad when you type in port numbers. Make sure to release the Control key before you start typing in a port number. Make sure you don’t wait too long before you enter a port number. Make sure you don’t accidentally hit keys such as Shift, Caps Lock, or Alt.

Characters that you type come up wrong or missing.

The keyboard mode that the currently selected CPU port is set for might not match the mode that the CPU on that port expects. See item D under the “You can’t switch ports from the keyboard” section above.
