Chapter 5. Solving problems
This chapter provides basic troubleshooting information to help you solve some
common problems that might occur while you are setting up the server.
If you cannot locate and correct the problem using the information in this chapter,
see Appendix A, "Getting help and technical assistance," on page 77, the Problem
Determination and Service Guide on the IBM xSeries Documentation CD, and the
"Server Support" flowchart in the front of this document.
Diagnostic tools overview
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST beep codes
v ServerGuide problems
v Troubleshooting tables
v Diagnostic programs and error messages
v System-board error LEDs
POST beep codes
When POST is completed successfully, no beep occurs. If POST detects a problem
during startup, beep codes might occur. Use the following beep code descriptions to
help diagnose and solve problems that are detected during startup.
Note: See the Problem Determination and Service Guide on the IBM xSeries

The power-on self-test beep codes indicate the detection of a problem.
– No beep indicates successful completion of POST, with no errors.
– More than one beep indicates that POST detected a problem. Error messages
also appear during startup if POST detects a hardware-configuration problem.
For more information, see "POST beep codes" and the Problem Determination
and Service Guide on the IBM xSeries Documentation CD.
This chart lists problem symptoms and steps to correct problems that occur when
you are using the ServerGuide Setup and Installation CD. For more information,
see "ServerGuide problems" on page 63.
These tables list problem symptoms and steps to correct the problems. For more
information, see "Troubleshooting tables" on page 63.
The diagnostic programs are the primary method of testing the major
components of the server. These programs are on the IBM Enhanced
Diagnostics CD that comes with the server. See the Problem Determination and
Service Guide on the IBM xSeries Documentation CD for more information.
An LED on the system board might be lit to help isolate an error that is indicated
by the system-error LED on the front of the server. For more information, see
"System-board LEDs" on page 76.
