To identify the RJ-45 cable type, hold the two ends of the cable next to each other so that you can see the colored
wires inside the ends, as shown in
Figure 4 RJ-45 Cable Identification
Examine the sequence of colored wires to determine the type of RJ-45 cable, as follows:

Straight-through—The colored wires are in the same sequence at both ends of the cable.

Crossover—The first (far left) colored wire at one end of the cable is the third colored wire at the other end of
the cable.
Table 1 lists the rolled (console) cable pinouts for RJ-45.
