Console Port (RJ-45)
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 A-2 shows the RJ 45 cable.
Figure A-2 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 A-3.
Figure A-3 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 A-1 lists the rolled (console) cable pinouts for RJ-45.
