The POST error log contains the three most recent error codes and messages that
the system generated during POST. The System Error log contains all messages

You can view the contents of the System Error log from the Configuration/Setup

Viewing error logs from the diagnostic programs
Start the diagnostic programs; select Hardware Info from the top of the diagnostic
programs screen; select System Error Log from the list that appears; then, follow
the instructions on the screen. See "Starting the diagnostic programs" for more
information.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradeable read-only memory
(ROM) on the system board. These programs are the primary method of testing the
major components of your server.
Diagnostic error messages indicate that a problem exists; they are not intended to
be used to identify a failing part. Troubleshooting and servicing of complex
problems that are indicated by error messages should be performed by trained
service personnel.

displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
Starting the diagnostic programs
Complete the following steps to start the diagnostic programs:

to correct the cause of the first error message. After you correct the cause of
the first error message, the other error messages usually will not occur the next
time you run the test.
