This appendix describes the ASA 5585-X Ethernet, management, console, and auxiliary ports, and includes the following sections:

ASA 5585-X Cables

The ASA 5585-X uses the following cables:

  • For the Ethernet ports you can use either straight-through or cross-over twisted-pair cables because all RJ-45 Ethernet ports support MDI/MDIX.

Note Auto-MDI/MDIX refers to the ability of the PHY associated with a given port to sense and automatically switch (if required) the transmit and receive signaling across a twisted-pair RJ-45 cable, thereby eliminating the need for special (for example, cross-over) cables based on the connecting port.


  • The management ports are 10/100/1000 Mbps-capable; you can also use either straight-through or cross-over twisted-pair cables since the ports also support MDI/MDIX.
  • The console and auxiliary ports are serial ports and require the use of a flat rollover cable for terminal server connectivity (and a DB9 connector for connection to a PC).

RJ-45 Ethernet Ports

The ASA 5585-X supports 10/100/1000BaseT ports. You must use at least a Category 5 cable for 100/1000Base-TX operations. You can use a Category 3 cable for 10Base-TX operations.

Figure A-1 shows the 10/100BaseT (RJ-45) port pinouts.

Figure A-2 shows the 10/100/1000BaseT (RJ-45) port pinouts.

Management 10/100/1000 Ethernet Port

The management port is a 10/100/1000-Mbps Ethernet port with an RJ-45 connector. You can use a modular, RJ-45, straight-through UTP cable to connect the management port to an external hub, switch, or router.

Figure A-3 lists the cable pinouts for 10/100/1000BASE-T management port cable pinouts (MDI/MDIX).

Console and Auxiliary Ports (RJ-45)

Figure A-4 shows the RJ 45 cable.

Figure A-4 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-5.

Figure A-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.
  • Roll-over—The colored wires are in the opposite sequence at either end of the cable.

Table A-1 lists the roll-over (console) cable pinouts for RJ-45.
