Crossover Cables

When making an uplink connection between one hub and

another (or between a hub and a switch or bridge) using X -type

jacks at both ends, you must use a crossover cable. In a

crossover cable, two pairs of wires are switched at one end.

Carry out the following steps to create a crossover twisted-pair

cable:

1. Leave one end of the cable as-is, with the wiring on the

RJ-45 connector unchanged. The wiring needs to be

modified at one end only.

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:

1 2 ... 7 8 9 10 11 12 13
