• 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. Class 0 is the default for PDs. However, to
improve power management at the PSE, the PD may opt to provide a signature for
Class 1 to 3.
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 shall return Class 0 to 3 in accordance with the maximum power draw as
specified by Table 5-3.
