Cables and Connectors Appendix D
The PoE ports on the PoE expansion modules 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
When connecting the ports to 10BASE-T- and 100BASE-TX-compatible
devices, such as servers and routers, you can use a two or four twisted-pair,
straight-through cable that is 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 color of the wire that
is connected to the pin on the outside of the left plug must differ in color from
the wire that is connected to the pin on the inside of the right plug.
Figure 86 and Figure 87 show the cable schematics.
