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
Class 4 is defined for IEEE 802.3at high power used.

PoE Schedule

PoE Schedule allows user to scheduling PoE power supply. User has to define when system supplies PoE power from a time
table as following screen shot, and there are 4 profiles totally for user applying PoE power supply strategy. The web screen in
Figure 4-13-3 appears.
It shows the PoE device current watt.
It can limit the port PoE supply watts.
Per port maximum value must less than 15.4 watts, total ports values must
less than the Power Reservation value if current PoE mode is 802.3af.
Per port maximum value must less than 30 watts, total ports values must less
than the Power Reservation value if current PoE mode is 802.3at.
Once power overload detected, the port will auto shut down and keep on
detection mode until PD's power consumption lower than the power limit value.
