Analysis
A switch supporting PoE has certain specifications in PoE power supply. When the total supplied power
exceeds the maximum power supply capacity of the switch, the switch automatically disconnects some
ports with lower priority. Therefore, APs attached to these ports will restart.
Check the log information on the switch:
