POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of tests
is called the power-on self-test or POST.
If POST finishes without detecting any problems, a single beep sounds and the first
screen of your operating system or application program appears.
If POST detects a problem, more than one beep sounds and an error message appears
on your screen. See “POST error messages” for more information.
Notes:
1. If you have a power-on password set, you must type the password and press
Enter, when prompted, before POST will continue.
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 usually will not occur the next time you
run the test.
POST error messages
The table “POST error codes” on page 90 provides information about the POST error
messages that can appear during startup.
Event/error logs
The POST error log contains the three most recent error codes and messages that the
system generated during POST. The System Event/Error log contains all messages
issued during POST and all system status messages from the Advanced System
Management Processor.
To view the contents of this error log, start the Configuration/Setup Utility program;
then, select Event/Error Logs from the main menu.
Small computer system interface messages
The following table lists actions to take if you receive a SCSI error message.
Note: If the server does not have a hard disk drive, ignore any message that indicates
that the drive is not installed.
You will get these messages only when running the SCSISelect Utility. See “SCSI error
codes” on page 95.
