POST
When you turn on the server/workstation, it performs a series of tests to check the
operation of server/workstation components and some of the options installed in
the server/workstation. 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 127 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/workstation 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 131.
