In this mode the Maximum Power fields have no effect. 
 
  Allocation mode 
In this mode the user allocates the amount of power that each port may reserve. The 
allocated/reserved power for each port/PD is specified in the Maximum Power fields. The ports 
are shut down when total reserved powered exceeds the amount of power that the power supply 
can deliver. 
 
In this mode the port power is not turned on if the PD requests more power 
the available. 
 
  Consumption mode 
In this mode the ports are shut down when the actual power consumption for all ports exceeds 
the amount of power that the power supply can deliver or if the actual power consumption for a 
given port exceeds the reserved power for that port. The ports are shut down according to the 
ports priority. If two ports have the same priority the port with the highest port number is shut 
down. 
 
  Priority mode 
In this mode the user assign the priority to the ports/PD. When the total PoE power consumption 
request is over the allowed power supply limitation, the system shut down PoE ports by port 
priority setting.
