Power over Ethernet (POE) – распиновка Power over Ethernet is a technology that allows IP telephones, wireless LAN Access Points, Security network cameras and other IP-based terminals to receive power, in parallel to data, over the existing CAT-5 Ethernet infrastructure without the need to make any modifications in it. Described by IEEE 802.3af standard. PoE integrates data and power on the same wires, it keeps the structured cabling safe and does not interfere with concurrent network operation. PoE delivers 48v of DC power over unshielded twisted-pair wiring for terminals consuming less than 13 watts of power. http://pinouts.ru/Net/poe.shtml IEEE 802.3af standard POE pinout: Pin Alternative A 1 Vport Positive 2 Vport Positive 3 Vport Negative Alternative B 4 Vport Positive 5 Vport Positive 6 Vport Negative 7 Vport Negative 8 Vport Negative POE devices pinouts of various manufacturers SOURCE Source 1 2 3 RX, RX, TX, protected DC+ DC+ DC- Voltage IEEE 802.3af using spare pairs REMARKS Ethernet RJ-45 connector pin number STANDARD IEEE 802.3af using data pairs LOAD 4 5 6 7 8 Load DC Load Voltage Connector Industry 48 V DC, spare spare TX, DC- spare spare (embedded) Standard for active PoE Industry 48 V DC, protected RX RX TX DC+ DC+ TX DC- DC- (embedded) Standard for passive PoE Usually Intel, Symbol, Orinoco 12 or 24 Cisco (OLD old standard) 48 V DC Cisco (NEW old standard) 48 V DC Most RX RX TX DC+ DC+ TX DC- DC- (embedded) V DC Brands of PoE Older Cisco RX RX TX DC- DC- TX DC+ DC+ (embedded) polarity is REVERSED New Cisco RX RX TX DC+ DC+ TX DC- DC- (embedded) is IEEE compliant Seen on Cisco (very unusual) D-Link 28 V DC DC+ DC- TX n.c. n.c.
