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.
On modular switches, although the percentage of used to budgeted power is measured by each PoE module, you can set the threshold for sending the event for the entire switch. That is, after any PoE module passes the configured threshold, the system sends an event.
The default value for this usage threshold is 70%. You can configure the usage threshold to be any integer between 1% and 99%.
