POWER OVER ETHERNET

Randy Frank -- Design News, February 6, 2006

PowerDsine 8012 High Power Midspan (http://rbi.ims.ca/4913-541). IEEE 802.3af defines how to safely obtain Power over Ethernet (PoE) connectivity from Power Sourcing Equipment (PSE) and eliminate external power supplies and ac/dc power cables. PoE provides power to high speed devices similar to the way telephones receive power through the same twisted pair carrying the voice. Targeting high power consumption Ethernet devices such as Pan-Tilt-Zoom (PTZ) network cameras and multi-channel wireless LAN access points, PowerDsine's 8012 midspan PSE has 12 ports that provide up to 39W per port. The unit includes automatic detection and protection and delivers power over an existing Cat5 LAN infrastructure. For more information on Power over Ethernet and IEEE 802.3af, go tohttp://rbi.ims.ca/4913-542.
