The standard RJ-45 pin assignments

Straight cable for use with MDI-II to MDI-X connections

With a crossover cable, two pairs of wires are switched at one connector end. Carry out the
following steps to create a customized, crossover twisted-pair cable:

1. Leave one end of the cable as is, with the RJ-45 connector intact. Only one end of the

cable’s wiring needs to be modified.

2. At the other end of the cable, connect wires 1 and 2 to contacts 3 and 6, respectively.

Likewise, connect wires 3 and 6 to contacts 1 and 2. Refer to the following diagram:
