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. 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.

Gigabit Ethernet networking has expanded to desktop connections in campus networking and to dense server connectivity in data centers. In short gigabit Ethernet has become mainstream with multiple use cases driving its growth. But a new generation of gigabit Ethernet switches is needed to satisfy market demands with attributes such as PoE-Plus, stacking, data center cooling, power efficiency and more. It’s these attributes and more that Extreme is delivering with its new Summit X460 Gigabit Ethernet switch. I talk with Darius Goodall, Senior Manager Product Marketing at Extreme Networks about the Summit X460 and the new network designs it enables.

In addition to desktop connectivity wiring closet switches now connect wireless access points, laptops, kiosks, netbooks, IP phones, printers, video desktop systems and more while also managing electrical power of the devices they connect. New PoE Plus standard 802.3at allow 30W per port to be delivered which has driven a change in wiring closet power management. I talk with Berna Devrim, Sr. Manager, Access Switching Marketing at Cisco Systems about the dynamics forcing a change in wiring closet switching and the new Cisco X and S series of edge switching products which represent progressive thinking in this space. Enjoy, Nick.
