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 diagnose and correct a problem by using the information in this
chapter, see Appendix A, "Getting help and technical assistance," on page 65, the
Problem Determination and Service Guide on the IBM
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 Troubleshooting tables
v Diagnostic programs and error messages
v System-board error LEDs

The power-on self-test (POST) codes indicate the detection of a problem.
– One 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.
See "POST beep codes" in the Problem Determination and Service Guide on
the IBM System x Documentation CD for more information.
These tables list problem symptoms and actions to correct the problems. See
"Troubleshooting tables" on page 50 for more information.
The system diagnostic programs are provided on the IBM Enhanced Diagnostics
CD. These programs test the major components of the server. See "POST beep
codes" on page 40 and the Problem Determination and Service Guide on the
IBM System x Documentation CD for more information.
When the system-error LED on the front of the server is lit, an LED on the
system board might also be lit to help isolate an erro. See "System-board error
LEDs" on page 61 for more information.
