Global Configuration
Command Usage
◆ Setting a maximum power budget for the switch enables power to be centrally
managed, preventing overload conditions at the power source.
◆ If the power demand from devices connected to the switch exceeds the power
budget setting, the switch uses port power priority settings to limit the
supplied power.
Example
Console(config)#power mainpower maximum allocation 180
Console(config)#

the no form to turn off power for a port, or the no form with the time-range
keyword to remove the time range settings.
Syntax

no power inline [time-range]
time-range-name - Name of a time-range during which PoE is supplied to
the attached device. (Range: 1-30 characters)

Command Usage
◆ The switch only provides power to the Gigabit Ethernet copper-media ports.
◆ When detection is enabled for PoE-compliant devices, power is automatically
supplied when a device is detected on the port, providing that the power
demanded does not exceed the port’s power budget or the switch’s power
budget.
