POST beep codes
The power-on self-test beep codes indicate the detection of a problem.
— One beep indicates successful completion of POST.
— 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 code descriptions" on page 50 and the Troubleshooting Guide
on the IBM xSeries Documentation CD for more information.
Troubleshooting charts
These charts list problem symptoms and steps to correct the problems. See the
"Troubleshooting charts" on page 52 for more information.
Diagnostic programs and error messages
The system diagnostic programs are provided in ROM. These programs test the
major components of your server.
Notes:
1. The diagnostic programs and error messages are specific to each server.
When running diagnostics and reading error messages of two merged
servers, be sure that you know which server gave the error before attempting
any repairs or change any settings.
