Description
Click to select ports to be configured and they will be displayed in the
Selected Ports list box.
Enable or disable PoE on the selected ports.

The system does not supply power to or reserve power for the PD
connected to a PoE port if the PoE port is not enabled with the PoE
function.

You are allowed to enable PoE for a PoE port if the PoE port will not
result in PoE power overload; otherwise, you are not allowed to enable
PoE for the PoE port.
By default, PoE is disabled on a PoE port.
IMPORTANT:
PSE power overload—When the sum of the power consumption of all ports
exceeds the maximum power of PSE, the system considers the PSE is
overloaded.
Set the maximum power for the PoE port.
The maximum PoE port power is the maximum power that the PoE port can
provide to the connected PD. If the power required by the PD is larger than
the maximum PoE port power, the PoE port will not supply power to the PD.
By default, the maximum power of a PoE port is 30000 milliwatts.
