Description 

 

System PoE Admin 

Mode 

Allows user enable or disable PoE function. It will causes all of PoE ports supply 

or not supply power. 

 

PoE Temperature 

Protection 

Allows user enable or disable PoE Temperature Protection. 

 

PoE Management 

Mode 

There are Six modes for configuring how the ports/PDs may reserve power and 

when to shut down ports. 

 

Class-Consumption mode:

 System offers PoE power according to PD real 

power consumption.   

 

Class-Reserved-Power mode:

 System reserves PoE power to PD 

according to PoE class level. 

 

Allocation-Consumption mode:

 System offers PoE power according to PD 

real power consumption.   

 

Allocation-Reserved-Power mode:

 Users allow to assign how much PoE 

power for per port and system will reserves PoE power to PD. 

 

LLDP-Consumption mode:

 System offers PoE power according to PD real 

power consumption.   

 

LLDP-Reserved-Power mode:

 System reserves PoE power to PD 

according to LLDP configuration. 

 

Power Supply Budget 

[W] 

Set limit value of the total PoE port provided power to the PDs. 

NS3702-24P-4S

 available maximum value is 

440

. 

 

Temperature 

Threshold 

Allows setting over temperature protection threshold value. It system 

temperature was over it then system lower total PoE power budget automatically. 

 

PoE Usage Threshold 

Allows setting how much PoE power budget could be limited. 

 

Buttons 

: Click to apply changes   

: Click to undo any changes made locally and revert to previously saved values. 

 

 

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.
