Power-On Self Test (POST)

When the server boots, a series of tests are displayed on the screen. The number of tests
displayed depends on the configuration of the server.
The POST, 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 will be accurately isolated by the POST.
To see the POST:
•
The HP server must be functionally able to run POST.
•
The video subsystem must be functional.
•
The keyboard must be functional.
NOTE: BIOS ROM version number is displayed on the monitor screen during power-up.

WARNING: You should always turn off the power and disconnect the power cord to the
server before opening the HP server and touching the internal components. Failing to
do so can expose you to electric shock and the server's components to damage. The
power switch does NOT turn off standby power, so disconnect the power cord to turn
off standby power.
