Command Usage
â—† If the power demand from devices connected to all switch ports exceeds the
power budget as determined during bootup, the port power priority settings
are used to control the supplied power. For example:
â–
If a device is connected to a low-priority port and causes the switch to
exceed its budget, power to this port is not turned on.
â–
If a device is connected to a critical or high-priority port and would cause
the switch to exceed its power budget, power is provided to the port only if
the switch can drop power to one or more lower-priority ports and thereby
remain within its overall budget.
Power will be dropped from low-priority ports in sequence starting from
port number 1.
If priority is not set for any ports, power is denied in reverse sequence,
starting from Port 12/24.
â–
If sufficient power cannot be freed up for a critical or high-priority port by
turning off power to lower-priority ports, power will not be supplied to the
newly connected device.
â—† If priority is not set for any ports, and there is not sufficient power to supply all
of the ports, port priority defaults to Port 1, Port 2, Port 3 ... Port 12/24, with
available power being supplied in that sequence.
