HP NetServer LXr Pro8 Beep
Codes
If the POST Routines cannot display messages on the monitor
when an error occurs before the video display is initialized,
generally the BIOS POST error message usually displays on the
HP NetServer's message display (located on the control panel). In
a few cases, the server emits a series of beeps. The beep codes
are defined in the table below.
