z Monitoring PoE power means monitoring the voltage of the PoE power.
z When the current power utilization of the PSE is above or below the alarm
threshold for the first time, the system will send a Trap message.
z When the PSE starts or stops supplying power to a PD, the system will send a
Trap message, too.

Optional
90 V by default.
Configure an AC input over-voltage
threshold for the PoE power
poe-power
input-threshold

Optional
264 V by default.
Configure a DC output under-voltage
