PoE ports integrate power and data signals on the same wires. The ports use
standard RJ45 connectors and Ethernet pinouts with internal crossovers.

Connect to 10BASE-T- and 100BASE-TX-Compatible Devices
The auto-MDIX feature is enabled by default. Follow the cabling guidelines
below when the auto-MDIX feature has been disabled.
When connecting the ports to 10BASE-T- and 100BASE-TX-compatible
devices, such as servers, workstations, and routers, you can use a two or four
twisted-pair, straight-through cable wired for 10BASE-T and 100BASE-TX.
To identify a crossover cable, compare the two modular ends of the cable. Hold
the cable ends side-by-side, with the tab at the back. The wire connected to the
pin on the outside of the left plug must be a different color from the wire
connected to the pin on the inside of the right plug.
The following figures show these schematics:
• Two twisted-pair, straight-through cable
• Four twisted-pair, straight-through cable
