Using Power Over Ethernet to Reduce Network Energy Consumption
Power over Ethernet (PoE) technology has become an increasingly important tool for simplifying network deployment while improving overall energy efficiency. The latest advances have presented new opportunities to further reduce power consumption and associated energy costs. PoE enables data and power to be carried over a single Ethernet cable. The technology delivers up to 60 Watts (W) of safe, uninterrupted power over the existing LAN infrastructure to Powered Devices (PDs), at voltages from 50 to 57 Volt (V) levels, in support of the latest high-power IEEE802.3at-2009 standard.
