Power-on self-test (POST)
When you turn on the server, the power-on self-test (POST) performs a series of
tests to check the operation of system components and some of the installed
options.
If POST finishes without detecting any problems, the first window of your operating
system or application program appears.
If POST detects a problem, more than one beep might sound, an error message
might appear on your screen, or both.
Notes:
1. If you have a user password set, you must type the password and press Enter,
when prompted, before the operating system will load.
2. A single problem might cause several error messages. When this occurs, work
to correct the cause of the first error message. After you correct the cause of
the first error message, the other error messages typically will resolve the next
time you run the test.
POST beep codes
The possible types of beep codes are:
No beeps
No beep codes indicates that your server successfully completed POST
without finding any errors.
Continuous beep
Your startup (boot) microprocessor has failed, or your system board or
speaker subsystem might contain a failing component. If the system
continues through POST with no errors, call for service. If no video appears,
the startup processor has failed.
Beep codes for specific failures
Beep codes indicating specific system problems are listed in the Hardware
Maintenance Manual and Troubleshooting Guide on the IBM xSeries
Documentation CD.
POST error messages
The following table provides an abbreviated list of the error messages that might
appear during POST.
Note: See the Hardware Maintenance Manual and Troubleshooting Guide on the
