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. The following is an example of a POST error message:
028 --- CMOS Date/Time not set
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.

If the POST failure is during a routine bootup, verify the following conditions:
