By default, PoE is disabled on a PoE port. Power Max 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. 1-3
