Cable Pinouts

This appendix describes pinout information, and includes the following sections:

10/100/1000BaseT Ports

The adaptive security appliance 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. Ethernet ports normally use MDI connectors and Ethernet ports on a hub normally use an MDI-X connector.

Use an Ethernet straight-through cable to connect an MDI to an MDI-X port. Use a cross-over cable to connect an MDI to an MDI port, or an MDI-X to an MDI-X port.

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

Figure 1-2 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 1-3 shows the RJ 45 cable.

Figure 1-3 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 1-4.

Figure 1-4 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 1-1 lists the rolled (console) cable pinouts for RJ-45.

MGMT 10/100 Fast Ethernet Port

The MGMT 10/100 Fast Ethernet port has 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.

Table 1-3 lists the cable pinouts for 10/100BASE-T Management Port Cable Pinouts (MDI).
