  • Why doesn't a patch panel screw up the wiring?

    I'm a relative newbie at this, but it seems to me that a properly wired patch panel reverses the wires.

    Typically, the 8 pins on the computer port, as you look at it, are from left to right 1,2,3,4,5,6,7,8...You run a cat5 cord from that computer to a router and, from left to right on the router, the coordinated pins are 8,7,6,5,4,3,2,1. Routers expect this, no problem.

    Now you go to a patch panel. You have the computer with say the blue wire on the left as you look at the port. That blue wire wants to be at pin 8 on the router (the right hand side, see above). You put it to a patch panel. Now it's on pin 8 (right side) into the patch panel. On the other end of the patch, pin 8 (right side) is still blue. You connect your cord to that with blue on the left. What was once wire 8 in the patch cord is now connected to what should be pin 1, blue. You run that to the router and now the blue wire into the router is on the right but it's not the same data because the patch panel didn't reverse them...

    I'm going insane over-thinking this.
