    Hi.

    I have a customer with a cat6 from his house to a workshop on his land further up. Most of the run is underground, and the pipe is fair tight.

    3 of the cores are damaged at some point and he's reluctant to pull a new cable in if he can avoid it since its a massive run, although I have stressed that this is the best option.

    If cores are in order 1 to 8 if I remember correctly it was 3, 4, and 5 that were damaged. maybe 4, 5, and 6. (Either way both blues and one of of the greens.)

    As I understand it, the greens are the issue as the blues are not connected in a switch or router, so If I did a little moving around of the order of the cores and replace browns with the greens say, in the rj45 plug, could this work?

    This cable is going straight from a router to a switch, no PoE or anything like that.

    For the record I have googled it but I've seen different options on what the cores actually do, so I just need some guidance.

    I'd go with Yes. As long as you are replacing a damaged twisted pair with a unused twisted pair I can't see the problem.

    If it's only being used for 10/100 speeds then reusing the other cores should prove successful. If it's being used for Gig ethernet, gig requires all 4 pairs so it would not be possible.
