PD classifications
A PD may be classified by the PSE based on the classification information provided by
the PD. The intent of PD classification is to provide information about the maximum
power required by the PD during operation. The PD provides a signature about Class
level to improve power management at the PSE.
The PD is classified based on power. The classification of the PD is the maximum
power that the PD draws across all input voltages and operational modes.
A PD will return to Class 0 to 4 in accordance with the maximum power draw as
specified below:
