Cisco Stokes PoE Lighting Push with Dedicated Ethernet Switch, Signs Up Marriott

The IT company’s Digital Building Ethernet box will support lighting, heating, security, and other building operations without the electricity losses associated with some PoE schemes. Hoping to solve some of the shortcomings of Power-over-Ethernet technology, Cisco Systems introduced a new Ethernet data switch optimized for building operations including lighting, and said that a Marriott Hotel and a Swiss commercial office headquarters are pioneering its use. Like Cisco’s general line of Ethernet switches, the new box knocks voltage down from the 120V and 240V electrical lines that feed it, transforming it into a lower voltage that is sufficient to power LED lights — renowned for low energy needs — and that can travel safely over standard Ethernet cable, commonly referred to as Cat5 and Cat6. http://www.ledsmagazine.com/
