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
components or assemblies have failed. Once the beep code sequence is complete, it
repeats. 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 continues to repeat.
