10. APPENDIX
10.1 Shutdown Retry Logic
The function of the built-in shutdown routine is to protect the repeater from any further damage from a hard-
fail that the system may be experiencing.
Within 5 seconds of a hard-fail alarm being detected, the repeater will start the shutdown routine. The
repeater will shut down by powering of the HPAs (high-powered amplifiers) for 30 seconds.
After 30 seconds have elapsed, the repeater will power on the HPAs and check to see if the hard-fail alarm still
exist. If the hard-fail alarm still exists, then the repeater will shut down for 1 minute (double the time of the
previous shutdown time).
After 1 minute has elapsed, the repeater will power on the HPAs and check to see if the hard-fail alarm still
exist. If the hard-fail alarm still exists, then the repeater will shut down for 2 minutes (double the time of the
previous shutdown time).
The shutdown routine will repeat itself a total of 10 times. If the hard-fail alarm still exists after the 10th retry,
then the repeater will turn off its HPAs permanently until a reset is performed or factory set is executed.
