Power over Ethernet (PoE) and its impact on the CIO portfolioPoE is the transfer of electrical power, along withdata, to remote devices over standard data cablesin an Ethernet network (Cat3/Cat5/Cat5e/Cat6 ).
IEEE802.3af-2003 Specifications• The original IEEE 802.3af-2003 standard version of PoE supplies up to 15.4 W of DC power (minimum 44 VDC and 350 mA) to each device.• Only 12.95 W is assured to be available at the powered device (PD) as some power is dissipated in the cable.
IEEE802.3at-2009 Specifications• Cabling: CAT5E required• Power Feeding: 2-pairs and 4-pairs possible – Focus on 2-pairs Medium Power: PSE 30W output, PD 25.5W input – 4-pairs High Power should be based on 2x2-pairs: PSE 60W output, PD 51W input• IEEE 802.3az Energy-Efficient Ethernet – savings upwards of 3 watts per link
