failing. See the documentation that comes with the serial device for additional testing
information.
If the POST error message reappears, call for service.
Ensure that:
1. Nothing is resting on the keyboard and pressing a key.
2. No key is stuck.
3. The keyboard cable is connected correctly to the keyboard and to the correct
connector on the server.
If you just connected a new mouse or other pointing device, turn off the server and
disconnect that device. Wait at least 5 seconds; then, turn on the server. If the error
message goes away, replace the device.
1. Replace the diskette.
2. If the problem persists, make sure that the diskette drive cables are correctly
and securely connected.
3. If the problem remains, replace the diskette drive.
1. Verify that the Configuration/Setup Utility program correctly reflects the type
of diskette drive that you have installed.
2. Run the diagnostic tests. If the diagnostic tests fail, call for service.
If you removed a diskette drive, make sure that the diskette drive setting is correct
in the Configuration/Setup Utility program. If the setting is not correct, change it.
If you changed a hardware option, make sure that the parallel port setting is correct
in the Configuration/Setup Utility program. If the setting is not correct, change it.
If you have a modem, serial printer, or other serial device attached to your server,
verify that the serial cable is connected correctly. If it is, use the following
procedure:
1. Turn off the server.
2. Disconnect the serial cable from the serial port.
3. Wait five seconds; then, turn on the server.
