The system generates an SNMP event after a preset percentage of the reserved power for any slot or total power for a stand-alone switch is actually used by a connected PD. This preset percentage is called the usage threshold and is the percentage of the measured power to the budgeted power for each slot or total power for a stand-alone switch.
The default value for this usage threshold is 70%. You can configure the usage threshold to be any integer between 1% and 99%.
