 Priority The Priority represents PoE ports priority. There are three levels of power priority
named Low, High and Critical.
The priority is used in the case when total power consumption has been over
total power budget. In this case the port with the lowest priority will be turn off,
and offer power for the port of higher priority.
 Power Allocation It can limit the port PoE supply watts. Per port maximum value must less than
30.8W watts , total ports values must less than the Power Reservation value.
Once power overload detected, the port will auto shut down and keep on
detection mode until PD’s power consumption lower than the power limit value
