Appendix D: 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 10
th
retry, then the repeater will turn on its HPAs permanently until a reset is
performed.
