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
(see Table A-2).
• 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 (see Table A-3).
• Rolled—The colored wires at one end of the cable are in the reverse sequence of the colored wires
at the other end of the cable (see Table A-4).
