· • Low priority port will be shutdown. When a newly
powered device is connected, the switch searches
among its currently connected and powered devices. If
any port has lower priority than the newly connected
port, the switch discontinues the power supply to the
lower priority port and provides power to the newly
connected port. If this power budget from disabling
one low priority port is not enough, the switch disables
the next low priority port and so on until the power
budget is enough. If there are no low priority ports or
not enough power, the newly connected device is not
powered.
Power Usage Threshold: The Power Usage Threshold is the threshold to enable the
SNMP trap. The default value is 80% and is configurable by the
administrator. If the power budget is consumed, an SNMP trap
is sent to the associated receivers. If an SNMP trap receiver is
defined, no SNMP trap is sent.
