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.
