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. 12 Hardware Maintenance Manual: xSeries 330 Type 8674, IntelliStation R Pro Type 6851, and Network Equipment Building System Type 8674

:
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
