There are eight wires in an Ethernet cable, connected to pins 1-8 on the connector. The Ethernet signal is carried on the 3/6 and 1/2 pairs (green and orange wires). For passive POE, pins 4 and 5 (blue) get +12 volts, and pins 7 and 8 (brown) are ground.
(A wire pair is actually one wire of solid color and one white wire with a like-colored stripe.)
You can find more information by doing a web search on "passive power over ethernet".

The ones we are using are from a prior year's First Choice, part number FC14-022. I'm pretty sure they are the same as what is available here:

Any short Ethernet extension should be usable.
As a proof of concept, I also pulled apart a cheap Ethernet coupler (similar to
http://www.cablewholesale.com/produc...mc-8p8c-st.php), stripped the appropriate wires inside it, and soldered on power wires that exit the coupler through a small hole I drilled in the bottom. It would require two Ethernet patch cables to use it, one going to the roboRIO and one to the OM5P.
