Spare Pair and Data Pair powering - ULTRA Power midspans stk nos. 666-8211 (POE60U single-port) and 666-8220 (POE80U single-port), have a combination of Spare Pair and Data Pair powering over the full 8 wires. There are no specific IEEE standards for these yet. The midspans are compliant to the performance of 10baseT, 100baseT and 1000baseT (Gigabit). They have safety features, such as handshake detection, overload, connect and disconnect functionality as for the IEEE802.3af and IEEE802.3at standards but the handshake detection resistance is 12.5KΩ, instead of 25KΩ for the IEEE802.3af and IEEE802.3at standards
