PD Class will show by learning from the link partner no matter which “Reserved Power determined by”

30W, PD class still stays at the previous learned Class.

Class 0: Max. power 15.4 W
Class 1: Max. power 4.0 W
Class 2: Max. power 7.0 W
Class 3: Max. power 15.4 W

Power Allocated: Shows the amount of power the switch has allocated for the PD. Power gets
updated to power negotiation by Class, the value assigned and displayed is forced. When Power
override =1, the value is the same as the value of “Maximum Power (W)”.
The Switch provides power to the PD if the power required by the PD is less than this value.
