Chapter 1 Managing Single Entities

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.
