SERVSWITCH™ JR. MP

5.2.2YOU CAN’T SWITCH PORTS FROM THE KEYBOARD

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

B. The ServSwitch Jr. MP 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.

C. The keyboard mode that the currently selected CPU port is set for doesn’t match the mode that the CPU on that port expects. Issue the Set Keyboard Mode command to change the port’s mode (see Section 4.3.10). 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.

D. For PS/2 type equipment, if the keyboard and mouse strands of the CPU cable have been reversed, plug them into the proper ports.

E. 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 or Alt.

5.2.3CHARACTERS THAT YOU TYPE COME UP WRONG OR MISSING (PC CPUS ONLY)

The keyboard mode that the currently selected CPU port is set for doesn’t match the mode that the CPU on that port expects. See item C under Section 5.2.2.

5.2.4YOU CAN’T SEEM TO SCAN OR SWITCH TO CERTAIN PORTS AT ALL (SW628A-R2 ONLY)

The Maximum Ports setting is too low. Set Maximum Ports to match the number of CPUs in your system. See Section 4.3.8.

5.2.5THE SERVSWITCH JR. MP SCANS OR SWITCHES TO EMPTY OR NONEXISTENT PORTS

(SW628A-R2 ONLY)

The Maximum Ports setting is too high. Set Maximum Ports to match the number of CPUs in your system. See Section 4.3.8.
