Configuring Port PoE Power
If a device is connected to a switch port and the switch detects that it requires more than the power budget of
the port, no power is supplied to the device (the port power remains off).
If the power demand from devices connected to switch ports exceeds the power budget set for the switch, the
port power priority settings are used to control the supplied power. For example:
If a device is connected to a low-priority port and causes the switch to exceed its budget, port power
is not turned on.
If a device is connected to a critical or high-priority port and causes the switch to exceed its budget,
port power is turned on, but the switch drops power to one or more lower-priority ports.
