◆ If a device is connected to a switch port and the switch detects that it requires
more than the maximum power allocated to the port or to the overall switch,
no power is supplied to the device (i.e., port power remains off).
Example

Command Usage
◆ If the power demand from devices connected to the switch exceeds the power
budget setting as determined during bootup, the switch uses port power
priority settings to control the supplied power. For example:
■
A device connected to a low-priority port that causes the switch to exceed
its budget is not supplied power.
■
If a device is connected to a critical or high-priority port and causes the
switch to exceed its budget, port power is still be turned on if the switch
can drop power to one or more lower-priority ports and keep within its
budget.
Power will be dropped from low-priority ports in sequence starting from
port number 1.
■
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.
◆ If a device is connected to a port after the switch has finished booting up and
would cause the switch to exceed its budget, power will not be provided to
that port regardless of its priority setting.
