10BaseT/100BaseTx Power & Data Out Port, Left Connector
The Power Bridge has a single Power & Data port configured as
MDI (non-crossover). This port is designed to carry Ethernet data
over the standard 2-wire pairs (RJ-45 pins 1/2 and 3/6) and DC
power source over the spare wire pair (RJ-45 pins 4/5 and 7/8).
The maximum segment length from the switch/hub to the
Network Interface Card (NIC), including the Power Bridge, is
100m (328 ft), per the IEEE 802.3 standard.
