Hi just trying to find out some documents and websites show that a crossover cable as one side T568A and the other side T568B and other documents show pins 4 5 and 7 8 crossed over as well.
Thanks

Why do you need such a cable? Most of the device in use today does that automatically.

If they don’t

We are working with some old pcs used as web servers windows nt with two network ports one for the network while the other one in used by by our webmaster to upload content that one must be crossover had some upgrades in the cable room and of course they removed all the old patch cables and put new ones in now the crossover cable was replaced by normal cable now upload does not work any more and all old patch cables have disappeared. Normal crossover yesterday but did not work will have to make one with all cables crossed and see if that works.
