Introduction
This document describes how to configure EnergyWiseHelper in a Windows PC host.
The Cisco EnergyWise Windows Helper is a slim service for Windows client machines to communicate with Cisco Energy Management (CEM) in environments where the native and agentless Windows Management Instrumentation / Windows Remote Management (WinRM) access is not feasible, for example, due to security objections or limitations within the network infrastructure.
The Cisco EnergyWise Windows Helper regularly communicates with the CEM Message Queue, and performs all the commands that it receives from it.
Prerequisites
Requirements
Cisco recommends that the Customer must have CEM and controller up and running.
Components Used
The information in this document is based on Host running Windows 7.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
