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 Hardware Maintenance Manual and
Troubleshooting Guide on the IBM xSeries Documentation CD for more
information.
These charts list problem symptoms and steps to correct the problems. See
"Troubleshooting charts" on page 50 for more information.
The system diagnostic programs are provided in ROM. These programs test the
major components of your server. See the Hardware Maintenance Manual and
Troubleshooting Guide on the IBM xSeries Documentation CD for more
information.
Use light path diagnostics to diagnose system errors quickly. See "Light path
