A. Can you do anything from the keyboard? If not, the keyboard cable has probably
come loose. Reconnect it.
B. The ServSwitch Jr. 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 might simply have gotten a little off kilter. If the Switch can see
the keyboard at all, try reinitializing the keyboard with the Reset command,
[Ctrl] R (see Section 4.3.4).
D. 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 4.3.11). 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 strands of the CPU 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 or Alt.
