We have encountered a situation in which some APs (between 3 and 10) drop all of the CBRS SMs links at the same time, once per night. It generally happens at 22:00 local.
Yes we have upgraded FW and sent engineering files.
It appears to be a result of the AP and the SMs loosing heartbeat with the SAS. It happens on PMP 450, 450i, and 450m. Not necessarily all the APs on a given tower either.
Has anyone else seen this problem?
