Configuring PoE Monitoring 1017
Configuring PoE
Monitoring
The PoE monitoring function involves monitoring of PoE power, PSE and PD.
■ Monitoring PoE power means monitoring the voltage of the PoE power.
■ 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.
■ When the PSE starts or stops supplying power to a PD, the system will send a
Trap message, too.

CAUTION: The under-voltage threshold should be less than the over-voltage
threshold.
