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 119 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 Light path diagnostics
v Error symptoms
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.

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 12 for more information.
Your server has light-emitting diodes (LEDs) to help you identify problems with
server components. These LEDs are part of the light-path diagnostics that are
built into the server. By following the path of lights, you can quickly identify the
type of system error that occurred. See "Light path diagnostics" on page 15 for
more information.
These charts list problem symptoms, along with suggested steps to correct the
problems. See the "Diagnosing errors" on page 22 for more information.
