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