Chapter 3. Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with the server.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
• POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST” on page 12
for more information.
• 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. See “Diagnostic programs and error
messages” on page 15 for more information.
• Light Path Diagnostic
The Light Path Diagnostic is used to quickly identify system errors.
