Power Levels
Power Levels
The devices in an EnergyWise network are from different manufacturers. To manage power usage consistently, EnergyWise uses a set of power levels.
If a domain member sends an end point a request to change the power level, the end point determines the appropriate action.

The range is from 0 to 10.
The default is 10.
A Cisco switch does not support level 0. You cannot turn off the power on a switch.
A PoE end point, such as IP phone, receives power from a PoE switch port.
•The power level is for the port.
•The port supports levels 0 to 10.
•If the port power level is 0, the port is powered off.
•If the power level is from 1 to 10, the port is on.
