Failed Component Alarm Codes
This appendix describes failed component alarm codes.
Failed component alarm codes use Morse code dot and dash characters. The dot “ . ” is
a short tone sounding for one unit of time. The dash “ - ” is a long tone sounding for
three units of time.
Alarms, also referred to as beep codes, are presented in a sequence, starting with the
critical component failure alarm, which alerts you to a component problem or failure,
or a firmware mismatch. This alarm is then followed by alarms for whichever
component or assemblies have failed. Once the beep code sequence is complete, it
continues to repeat. To understand the beep codes, listen to the sequence of codes until
you can break down the sequence into its separate alarms. You can also check your
software or firmware for alarms, error messages or logs to isolate and understand the
cause.
For example, in the case of a fan failure in a power supply, you might first hear the
critical component failure alarm, followed by a power supply failure alarm from power
supply 0 or power supply 1, followed by a fan failure event alarm, followed by an
event alarm. This sequence will continue to repeat.
