Identifying Cable Pinouts


This appendix describes pinout information for 10/100/1000BaseT ports, console the RJ-45 to DB-9 ports, and the Management 10/100/1000 Ethernet ports.

This chapter includes the following sections:

10/100/1000BaseT Connectors

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 support 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 5-1 shows the 10BaseT and the 100BaseTX connector (RJ-45).

Figure 5-2 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, yet they are widely available from other sources.


Figure 5-3 shows the RJ 45 cable.

Figure 5-3 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 5-4.

Figure 5-4 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 5-1 lists the rolled (console) cable pinouts for RJ-45.

MGMT 10/100/1000 Ethernet Port

The MGMT 10/100/1000 Ethernet port is an 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.

Table 5-3 lists the cable pinouts for 10/100/1000BASE-T Management Port Cable Pinouts (MDI). (See Figure 5-2 for an illustration of the pinouts.)
