PoE Function Can enable or disable the PoE function.
Priority Set port priority for the POE power management
It can choose the “port priority”, value is “1~4”. High priority is “1”.
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 3 in accordance wi
th the maximum power draw as specified by Table 4.1.
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 less 15.4, total ports values must less than the Power
Reservation value.
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.
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 w
ith the maximum power draw as specified by T
able 4-1.
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
4 Not Allowed Reserved for Future Use
Table 4.1 Device class
Class 4 is defined but is reserved for future use. A Class 4 signature cannot be provided by a
compliant PD.
