Chapter 5. 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
the section on solving problems in the User’s Reference on the xSeries 360 Documen-
tation CD and the “Server Support” flowchart in the front of this booklet.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
• 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 beep code
descriptions” on page 34 and “POST error messages” on page 35 for more infor-
mation.
• 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 the solving problems section in the
User’s Reference on the xSeries 360 Documentation CD 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 infor-
mation panel. See “Light Path Diagnostics” on page 37 for further information.
• Troubleshooting charts
These charts list problem symptoms and suggested steps to correct the problems.
See “Troubleshooting charts” on page 37 for an abbreviated chart. See the solv-
ing problems section in the User’s Reference on the xSeries 360 Documentation
CD for a complete chart.
• Customized support page
You can create a customized support page that is specific to your hardware, com-
plete 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 regis-
tered products.
After you register and create a profile for your IBM products, you can diagnose
problems using the IBM Online Assistant and you can participate in the IBM dis-
