Chapter 6. Solving problems
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with your server.
If you cannot locate and correct the problem using the information in this section,
refer to “Getting help, service, and information” on page 115 for more information.
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 75
for more information.
• Diagnostic programs and error messages
The server diagnostic programs are stored in upgradeable 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 87 for more information.
• Diagnostic LEDs
Your 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
your server. Use the illuminated LEDs to identify the failing or incorrectly
installed components. See “Diagnostic LEDs” on page 99 for more information.
• Troubleshooting charts
These charts list problem symptoms and suggested steps to correct the
problems. See the “Troubleshooting charts” on page 101 for more information.
• 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
