Connecting Console and Auxiliary Port Cables

The Cisco ASR 1004 Router has a DCE-mode console port for connecting a console terminal and a DTE-mode auxiliary port for connecting a modem or other DCE device (such as another router) to your chassis. Figure 5-14shows the CON and AUX ports on the Cisco ASR 1000 Series RP1 route processor card.

Console port - CON

Auxiliary port - AUX

Note Both the console and the auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

The Cisco ASR 1004 Router uses RJ-45 ports for both the auxiliary port and the console port.

For console and auxiliary port pinouts for the RJ-45 connector, see Cisco ASR 1004 Router

Specifications, page A-5. Both ports are configured as asynchronous serial ports.

Step 1 Before connecting a terminal to the console port, configure the terminal to match the chassis console port as follows: 9600 baud, 8 data bits, no parity, 1 stop bits (9600 8N1).

Step 2 After you establish normal router operation, you can disconnect the terminal.

Connecting the Ethernet Management Port Cable

When using the Fast Ethernet Management port in the default mode (speed-auto and duplex-auto) the port operates in auto-MDI/MDI-X mode. The port automatically provides the correct signal connectivity through the Auto-MDI/MDI-X feature. The port automatically senses a crossover or straight-through cable and adapts to it.

However, when the Fast Ethernet Management port is configured to a fixed speed (10/100/1000 Mbps) through command-line interface (CLI) commands, the port is forced to MDI mode.

When in a fixed-speed configuration and MDI mode:
