Introduction
Understanding and controlling energy usage is a focus of businesses worldwide. Cisco EnergyWise, an
innovative architecture which is added to existing Cisco Catalyst switching portfolio, promotes
company−wide sustainability by reducing energy consumption across an entire corporate infrastructure.

Cisco EnergyWise architecture can power off devices powered via Power Over Ethernet (PoE). You can
power off devices based on a preconfigured schedule, or based on configurable thresholds if using
EnergyWise aware network management software. Devices managed via this technology include Cisco
Unified IP Phones, Cisco Aironet Access Points, Cisco Video Surveillance IP Cameras and other
PoE−compatible devices.

Because unplanned power outages are a normal occurrence, recovery from such an event has always been a
focus of Cisco product testing. Cisco takes great care to ensure the complete and timely restoration of service
after the device is powered on. When a phone is powered down using the EnergyWise technology, the event is
indistinguishable from an unplanned event from the device perspective, and the devices recover via the
normal processes that are in place today.
