The power-on self-test beep codes indicate the detection of a problem.
– On 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 code descriptions" on page 70 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 71 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 the light path diagnostics feature to identify system errors quickly. See "Light
path diagnostics feature overview" on page 76 for more information.
