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 85 for more information.
The following tools are available to help you identify and resolve hardware-related
problems:
•
POST beep codes
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.
•
Diagnostic programs and error messages
The server diagnostic programs are provided on the IBM Enhanced Diagnostics
CD. These programs test the major components of the server. See "Diagnostic
programs and error messages" on page 10 for more information.
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, the first window of the operating
system or application program appears.
Note:
1.
If you have a power-on password or administrator password set, you
must type the password and press Enter, when prompted, before POST
will continue.
2.
A single problem might cause several error messages. When this occurs,
work 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.
POST generates beep codes to indicate successful completion or the detection of a
problem.
•
One short beep indicates the successful completion of POST.
•
More than one beep indicates that POST detected a problem. For more
information, see "Beep symptoms" on page 85".
The possible types of beep codes that your system might emit are:
