When I look at crossover cables, this is not correct Assuming (1) above is correct, then I don't see how this can be correct.īoth kinds of crossover are correct, but for different Ethernet standards. When I look at pinout diagrams showing T568A and T568B, the odd number pins are all color/white with the even number pins solid color. I had always understood (and the Internet has it spewed in multiple places) that if I connect T568A on one side, and T568B on the other I am creating a crossover connection. I hypothesize maybe there is some differential signalling going on to allow it to work, and the pair orders don't make a difference, but that does not feel right?Ĭan anyone confirm that the LED colors are standard across most switches, and that an Orange only light (ie green not on) means there is a problem at the hardware (probably cabling) level? Assuming (1) above is correct, then I don't see how this can be correct. When I look at crossover cables, this is not correct, which makes sense to me. I further understand that if plugging into a gigabit switch this will still work because it does crossover correction. I strongly suspect that this is indicative of a problem - so questions. I have attempted to terminate my side as both T568A and T568B with the same result each time on the switch - An Orange light on the left side, nothing on the right. I'm trying to wire up an ethernet cable and I suspect the remote end is improperly terminated, but for various reasons I can only access one end, meaning I can't use a cable tester.
