Command Mode Global configuration mode Usage Guidelines The maximum power limitation of a port cannot be set and the port's power supported by the chip is considered by default as the maximum power. The power-supply priority of a port cannot be set and the default priority of this port is low. Preemptive: it is to enable the function of limiting the maximum power of a port. It is also to enable the power supply priority of a port. Non-preemptive: it is to enable the function of limiting the maximum power of a port. It is also to enable the power supply priority of a port. Preempt means that a new PD device will be normally powered by a high-priority power supply port if the new PD device is connected to this high-priority port in full load and at the same time the port with the lowest power-supply priority will be cut off from power supply. Non-preempt means that the power supply port with high priority will be notified that a PD device has accessed when this port is connected to a PD device in full load. 7 Power Over Ethernet Configuration Commands Example The following example shows how to set the power supply management mode to preemptive.
