Configure a DC output
over-voltage threshold for the
PoE power supply

Optional
The default DC output
over-voltage threshold is 55.00.
The under-voltage threshold should be less than the over-voltage threshold.
Configuring PSE Power Monitoring
The system sends a Trap message when the percentage of power utilization exceeds the alarm
threshold. If the percentage of the power utilization always keeps above the alarm threshold,
the system does not send any Trap message. Instead, when the percentage of the power
utilization drops below the alarm threshold, the system sends a Trap message again.
Follow these steps to configure a power alarm threshold for the PSE:
