Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
v POST beep codes and error messages
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.
v Error log
The POST error log contains the three most recent error codes and messages
that the system has generated during POST. The System Error Log contains all
the error messages that were issued during POST.
To view the contents of the error logs, start the Configuration/Setup Utility
program; then, select
Error Logs from the main menu. See “Viewing the System
Error log” on page 28 for more information.
v ServerGuide error symptoms
ServerGuide error symptoms are explained at “ServerGuide error symptoms” on
page 24.
v Diagnostic programs and error messages
The server diagnostic programs are stored on the IBM Enhanced Diagnostics
CD . These programs are the primary method of testing the major components of
your server. See “Diagnostic programs and error messages” on page 25 for more
information.
v Customized support page
You can create a customized support page that is specific to your hardware,
complete with Frequently Asked Questions, Parts Information, Technical Hints
and Tips, and Downloadable files. In addition, you can choose to receive
electronic mail (e-mail) notifications whenever new information becomes available
about your registered products.
After you register and profile your xSeries products, you can diagnose problems
using the IBM Online Assistant, and you can participate in the IBM discussion
forum. For more detailed information about registering and creating a customized
profile for your IBM products, go to the following addresses on the Web:

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.
Notes:
1. If you have a user 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.
