If the server stops without completing the POST, this indicates that a fatal system error
has occurred. Write down the data shown on the screen and note the beep patterns
(output beep code), which will help a service engineer to diagnose the problem.
The POST checks the server’s storage devices. Make sure their indicators light properly.
