If a device is connected to a port after the switch has finished
■
booting up and would cause the switch to exceed its budget, power
will not be provided to that port regardless of its priority setting.
If priority is not set for any ports, and there is not sufficient power
■
to supply all of the ports, port priority defaults to Port 1, Port 2, Port
3 ... Port 24, with available power being supplied in that sequence.
If priority is not set for any ports, and PoE consumption exceeds the
■
maximum power provided by the switch, power is shut down in the
reverse sequence, starting from Port 24.
