Cisco products use the following types of RJ-45 cables:
Straight-through
Crossover
Note: Cisco does not provide these cables, yet they are widely available from other sources.
Figure 3 shows the RJ 45 cable.
Figure 3 RJ-45 Cable
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.
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.
