•
Make sure that the C2T breakout cable is properly connected to the server.
•
Make sure that the server and the monitor are turned on.
•
Try using another keyboard.
Note: If you are using the C2T chain, see "Testing the C2T chain" on page 19.
If the items above are correct, call for service.

Verify that:
•
The memory modules are seated properly.
•
You have installed the correct type of memory.
•
If you changed the memory, you updated the memory configuration with the
Configuration/Setup Utility program.
•
All banks of memory on the DIMMs are enabled. The server might have
automatically disabled a DIMM bank when it detected a problem or a DIMM bank
could have been manually disabled.
Look in the POST error log for error message 289:
•
If the DIMM was disabled by a system-management interrupt (SMI), replace the
DIMM.
•
If the DIMM was disabled by the user or by POST:
1.
Start the Configuration/Setup Utility program.
2.
Enable the DIMM.
3.
Save the configuration and restart the server.
•
If you continue to get this error, replace the DIMM.
If the problem remains, call for service.
The startup (boot) microprocessor is not working properly.
Verify that the startup microprocessor is seated properly. If it is, replace the startup
microprocessor.
If the problem remains, call for service.
Some IBM monitors have their own self-tests. If you suspect a problem with your

instructions.
If you still cannot find the problem, call for service.
