successful test completion or the detection of a problem.
Troubleshooting charts
These charts list problem symptoms, along with suggested steps to correct the
problems. See the "Troubleshooting chart" on page 35 for more information.
Error log
The POST error log contains the three most recent error codes and messages
that the system generated during POST. The System Event/Error Log contains all
error messages issued during POST and all system status messages from the
system environmental monitor subsystem.
To view the contents of the error logs, start the Configuration/Setup Utility
program; then, select Error Logs from the main menu.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradable read-only memory
(ROM) on the system board. These programs are the primary method of testing
the major components of your server.
Note: Refer to the "Solving Problems" section in the User's Reference on the
