xSeries 440:Troubleshooting Guide
You can use the server with decreased memory.
If you just installed memory, verify that the new memory is correct for your server. Also verify
that the memory is installed and seated correctly. Start the Configuration/Setup Utility program
and select Memory Settings from the Advanced Setup menu to enable the DIMM.
If the problem remains, replace the failing DIMM.
Ensure that:
• Nothing is resting on the keyboard and pressing a key.
• No key is stuck.
• The keyboard cable is connected correctly to the keyboard and to the correct connector on
the server.
After installing a USB keyboard, you might need to use the Configuration/Setup utility to Enable
keyboardless operation and prevent the POST error message 301 from being displayed during
startup.
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.
