In the event of a hard fail alarm, the control board will shutdown the HPA (both
uplink & downlink) for 30 seconds and then turns on the HPA to check for a
repeated hard fail occurrence. If the next two occurrences sense a hard fail, the
control board will shutdown the HPA for 20 minutes (total of three consecutive hard
fails). After 20 minutes, the HPA will automatically come back alive and the control
board will check if the Hard Fail alarm has cleared. If it has not, the same process
will continue as mentioned above.
