Cisco Universal Power Over Ethernet: Unleash the Power of Your Network

Enterprise workspace is quickly evolving with new networked devices to improve communication, collaboration, security, and productivity. Power over Ethernet (PoE), a way to deliver electrical power over LAN cabling to networked devices, has been widely deployed over the years to provide power to various endpoints in the enterprise workspace environment. Cisco® Catalyst® 4500E, a market leader of PoE technology, continues to innovate to deliver Universal PoE (UPOE) technology with up to 60 watt power to enable even broader endpoint support, with additional benefits of higher availability, lower OpEx, and faster deployment.

This paper provides an overview of the Cisco UPOE technology. It describes how Cisco has evolved PoE technology to UPOE, the use case examples of UPOE to simplify enterprise deployment, and UPOE architecture and operations.

This paper provides a superb complement to the "IEEE 802.3az Energy Efficient Ethernet: Build Greener Networks" paper. While the prior paper concentrated on EEE, this continues the discussion of the capabilities supplied by various generations of POE.

In particular, it starts with a great discussion of the evolution of POE from the original ability to deliver 7 Watts of power to today's capability to deliver up to 60 Watts.

The latter part of the paper is specific to Cisco's UPOE capabilities. Regardless of your exact choice of supplier, this provides a great benchmark.
