Identifying And Diagnosing Hardware Problems - HP zx2000 Technical Reference Manual

Troubleshooting

identifying and diagnosing hardware problems

Should a hardware failure occur, the zx2000 LEDs, e-buzzer, and logs will help you identify the
problem:
■
System beeps and e-buzzer. The Workstation zx2000 has an e-buzzer that beeps in specific
patterns to identify errors when the system boots. The e-buzzer can also send encoded data
over the phone to help support representatives identify more complex problems.
■
LEDs. The lights on the front bezel of the workstation change color and blink in different
patterns to help identify specific hardware problems.
■
The System Event Log (SEL) and Forward Progress Log (FPL) provide additional
detailed information about errors identified by the e-buzzer and LEDs. (See "SEL and FPL
log entries" on page 4.)
If the LEDs, e-buzzer, and logs do not provide enough information for you to identify the
problem you are experiencing, HP also provides software diagnostic tools.
