4 Diagnostics

Diagnostic Tests

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 following are the kinds of errors a user might get with the HP
Netserver.
•
Built-in diagnostic Error Messages.
•
BIOS and other error messages. These are errors detected by the system BIOS outside the
built-in diagnostics or application errors.
To see the Power On Self Tests (POST):
• The HP Netserver must be functionally able to run the diagnostics.
•
The video subsystem must be functional.
•
The keyboard must be functional.
NOTE

Diagnostics Description

The diagnostics (Power On Self Test "POST") run automatically each time the Netserver 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 Netserver hardware
failures will be accurately isolated by the diagnostic
WARNING

HP Netserver DiagTools

The purpose of hardware diagnostic software is to provide tools for checking hardware problems. By design,
diagnostic software executes simple tests of each hardware component. Usually, such tests assure that
hardware is not the source of Netserver problems. This allows the user to eliminate hardware as the cause of
the problem and to focus on operating system configuration parameters, network connections, and
application software configuration parameters as the source of the problem.
If hardware problems are confirmed, the diagnostic software program can sometimes detect and diagnose
the subsystem or specific Netserver component causing of the problem. In addition, diagnostic tools can
capture information that allows support personnel to quickly assess the condition of the Netserver.
In order to be effective, diagnostic software tools must be used in the context of a wider troubleshooting
procedure.
BIOS ROM version number is displayed on the monitor screen during power-up.
You should always turn off the power and disconnect the power cord(s) to the
Netserver 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.
