This section provides basic troubleshooting information to help you resolve some
common problems that might occur with the server.
If you cannot locate and correct the problem using the information in this section,
refer to "Symptom-to-FRU index" on page 105 for more information.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
v POST beep codes, error messages, and error logs
v Diagnostic programs and error messages
v Error symptoms
v Diagnostic LEDs
POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of
tests is called the power-on self-test or POST.
If POST finishes without detecting any problems, a single beep sounds and the
first screen of the operating system or application program appears.

The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See "POST" for more
information.
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 the server. See "Diagnostic programs and error
messages" on page 13 for more information.
These charts list problem symptoms, along with suggested steps to correct the
problems. See "Diagnosing errors" on page 21 for more information.
The server has light-emitting diodes (LEDs) to help you identify problems with
server components. These LEDs are part of the diagnostics that are built into the
server. See "Diagnostic LEDs" on page 18 for more information.
