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 93, the Problem
Determination and Service Guide on the IBM System x3400 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

POST emits one beep to signal a successful completion. If POST detects a problem
during startup, other 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 System

The power-on self-test beep 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" and the Problem Determination and Service Guide
on the IBM System x3400 Documentation CD for more information.
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 79.
These tables list problem symptoms and steps to correct the problems. See
"Troubleshooting tables" on page 79 for more information.
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 System x3400 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 91.
