You are making the cables incorrectly, but this won't effect POE because the unused wires are supposed to go straight through and you are using DC for POE and not AC so which wires are matched doesn't matter.
But you should google for the correct wiring, if you don't use matched pairs for the RX and TX signals the signals will be weaker and you will be transmitting a lot of RF into the environment, it also means your cables can't be very long without getting a lot of errors, and finally it meansif someone else repairs one of these cables one day they might not notice you did it wrong and do one end correctly and then the cable won't work and could even damage the equipment if using POE. Really, the RF problem is the biggest thing, radios of all kinds are much less usable inside my lab in part because someone once made a lot of ethernet cables incorrectly and also we get packet errors when we really shouldn't. (The high concentration of class A computer equipment is a big part of the problem too.) PS If you are making your own cables anyway you can make very inexpensive POE for non-POE equipment by just building power plugs into the cable instead of using an injection block. -- Daniel << When truth is outlawed; only outlaws will tell the truth. >> - RLiegh On Mon, 8 Sep 2003, Michael Yellin wrote: ]Hello, ] ] I am considering doing POE.
