Use the undo poe utilization-threshold command to restore the default power alarm threshold of 

the PSE. 

By default, the power alarm threshold for the PSE is 80%. 

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. 

# Set the power alarm threshold of PSE 7 to 90%.

lower value: Specifies an under-voltage threshold in volts. The under-voltage threshold range, default 

under-voltage threshold, and recommended under-voltage threshold vary with devices. 

upper value: Specifies an over-voltage threshold in volts. The over-voltage threshold range, default 

over-voltage threshold, and recommended over-voltage threshold vary with devices. 

Use the poe-power input-threshold command to configure an AC input under-voltage/over-voltage 

threshold. 

Use the undo poe-power input-threshold command to restore the default. 

The default AC input under-voltage/over-voltage threshold varies with devices.
