RJ-45 Cables
Cisco products use the following types of RJ-45 cables:
• Straight-through
• Cross-over
• Rolled (console)
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 1-5.
Figure 1-5 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.
• Cross-over—The first (far left) colored wire at one end of the cable is the third colored wire at the
other end of the cable.
• Rolled—The colored wires are in the opposite sequence at either end of the cable.
