Configure EnergyWiseHelper in Windows PC for CEM

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.
