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:
