„ 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 4-15-1.
Class Usage Range of maximum power used by the PD
0 Default 0.44 to 12.95 Watts
1 Optional 0.44 to 3.84 Watts
2 Optional 3.84 to 6.49 Watts
3 Optional 6.49 to 12.95 Watts
