Chapter 6. Solving Problems
This chapter provides basic troubleshooting information to help you resolve some
common problems that might occur while setting up the server.
If you cannot locate and correct the problem using the information in this chapter, see
“Getting information, help, and service” on page 144 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 97
for more information.
• Diagnostic programs and error messages
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 111 for more information.
• Light Path Diagnostics feature
The server has light-emitting diodes (LEDs) to help you identify problems with
server components. By following the light path, you can quickly identify the type
of problem that occurred. The light path begins with the LEDs on the operator
information panel (also known as the front LED panel). See “Light Path
Diagnostics” on page 123 for more information.
• Troubleshooting charts
These charts list problem symptoms, and suggested steps to correct the
problems. See “Troubleshooting charts” on page 129 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.
