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. 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 to Class 0 to 8 in accordance with the maximum power draw as specified by

Since the IGS-4215 PoE Switch Series per PoE port supports 48~54V DC PoE power output, please
check and assure the Powered Device's (PD) acceptable DC power range is 56V DC; otherwise, it
will damage the Powered Device (PD).
