10/100/1000BaseT Ports

The ASA supports 10/100/1000BaseT ports. You must use at least a Category 5 cable for 100/1000baseT operations, but a Category 3 cable can be used for 10BaseT operations.

The 10/100/1000BaseT ports use standard RJ-45 connectors and supports MDI and MDI-X connectors. See the "Auto-MDI/MDIX Feature" section.

Figure A-1 shows the 10BaseT and the 100BaseTX connector (RJ-45).

Figure A-2 shows the 10BaseT, 100BaseTX, and 1000BASE-T connector (RJ-45).

Console Port (RJ-45)

Cisco products use the following types of RJ-45 cables:

Straight-through

Crossover


Note Cisco does not provide these cables; they are widely available from other sources.


Figure A-3 shows the RJ-45 cable.

Figure A-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 A-4.

Figure A-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 A-1 lists the rolled (console) cable pinouts for RJ-45.

SFP Fiber Ports


Note The fiber connections on the ASA only supports multimode fiber with LC connectors. There is currently no support for single mode fiber or SC connectors. The fiber modules are also not replaceable.
