if I reverse the orange and green pair on one end of a cat6 network cable, will it upset my network or will the switch "fix" the problem?

    Accepted Solution

    It will create a cross-over cable.  Unless you need a cross-over cable, do no do it.

    Some times the switches are smart enough to recognize this, but it's not a recommended thing.  And it might create a havoc for 1+ Gbps connections.

    I noticed there were 6 ports on one of 3 24 port switches punched down this way.
    I had been having some disconnects from some of the workstatioins and was wondering if this might be the cause.

    all modern switches have auto switching ports which will cross over the send and receive pairs when needed, usually when you connect two switches together one will 'switch' round how its using the cable.( this used to be done manually with crossover cables). All modern switches will detect a cross-over situation, whether its a crossover cable or a connection to another switch with a 'straight' cable and behave correctly which is what you are describing.

    it is not likely to be your problem, keep looking, could still be a cable issue, but not the fact its x-over

    I agree with both of these guys. In fact, the only time these days when you need a crossover is connecting two computers.
