 Allocation mode

 Auto mode

• Port class, if available

• Power allocation, if available

• Port power consumption.

 Consumption

 Priority mode

The default PoE management mode is “Auto mode”.

• Power Supply

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

For SGSW-24040P, the available max. value is 220, and for SGSW-24040P4,

the available max. value is 380.

• Local Port

This is the logical port number for this row.

• PoE Enabled

The PoE Enabled represents whether the PoE is enable for the port.

• Priority

The Priority represents the ports priority. There are three levels of power priority

named Low, High and Critical.

The priority is used in the case where the remote devices requires uses more

power than power supply can deliver. In this case the port with the lowest priority

will be turn off starting from the port with the lowest port number.

• Maximum Power

The Maximum Power value contains a numerical value that indicates the

maximum power in watts that can be delived to a remote device.

• Power Allocation

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.

Note. The system PoE mode have to set to Allocation mode then it effect.

For SGSW-24040P, the total PoE power reservation from Port-1~24 is up to 220W

For SGSW-24040P4, the total PoE power reservation from Port-1~24 is up to 380W

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.
