Diagnostics Description

The diagnostics (Power-On Self-Test "POST") run automatically 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 will
be accurately isolated by the diagnostic
Go to "View System Error", displayed on the bottom of the boot screen, for an explanation of each test.
You see a list of the errors that occurred and suggestions on how to resolve them. Use the Setup utility
(press F2 during the boot process) to make any changes to the configuration.
WARNING
CAUTION
BIOS ROM version number is displayed on the monitor screen during power-up.
You should always turn off the power and disconnect the power cords to the server
before attempting to remove the cover and touch 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 cords
to turn off standby power.
Do not operate the HP NetServer with any of its covers off for more than 60 minutes.
