Device class 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 4 in accordance with the maximum power
draw as specified by Table 4-16-1.
Current(mA) It shows the PoE device current Amp.
Consumption [W] It shows the PoE device current watt.
Power Limit
*
It can limit the port PoE supply watts.
Per port maximum value must be less than 15.4 watts, total ports values must
be less than the Power Reservation value if current PoE mode is 802.3af.
Per port maximum value must be less than 30 watts, total ports values must
be less than the Power Reservation value if current PoE mode is 802.3at.
Once power overload detected, the port will automatically shut down and keep
the detection mode on until PD’s power consumption is lower than the power
limit value.
1. Total PoE power reservation from Port-1~12 is a maximum of up to 180 Watts
and port-13 ~24 is a maximum of up to 180 Watts.
2. The priority function only working under Classification power limit mode.
3. This Power Limit function is reserved for further usage.
