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 (i.e., 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.
Note:
Power is dropped from low-priority ports in sequence starting from port number 1.
