System BIOS configuration 34
ensure that the server is properly functioning. This diagnostic function automatically runs each time the
server is powered on.
These diagnostics, which reside in the BIOS ROM, isolate server-related logic failures and indicate the
board or component that needs to be replaced, as indicated by the error messages. Most server
hardware failures are accurately isolated during POST. The number of tests displayed depends on the
configuration of the server.
POST error indicators
When POST detects a system failure, it will display a POST error message.
Recoverable POST Errors
Whenever a non-fatal error occurs during POST, an error message describing the problem appears
onscreen. These text messages are displayed in normal video (white text on black background). It
shows the details of the error.
In some cases an error message may include recommendations for troubleshooting or require that you
press the
Enter
key to display recommendations. Follow the instructions on the screen.
It is recommended that you correct the error before proceeding, even if the server appears to boot
successfully. If your system displays one of the messages marked below with an asterisk (*), write
down the code and message and contact your HP Customer Support provider.
When no POST error message is displayed but the server stops during POST, listen for beep codes.
Table 23
lists the most common POST error messages with their corresponding troubleshooting
recommendation.
