Console and Auxiliary Port Cable Connections

Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. The DCE-mode console port is for connecting a console terminal and the DTE-mode auxiliary port is for connecting a modem or other DCE device (such as a CSU/DSU or other router) to your router.

Step 1 Before connecting a terminal to the console port, configure the terminal to match the router console port as follows: 9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2).

Step 2 Use an auxiliary and console port cable. (An auxiliary port and console port cable and adapter kit is available from Cisco Systems—Product Number ACS-2500ASYN=.) Use the console cable to connect the terminal to the console port. After you establish normal router operation, you can disconnect the terminal.

Note You must supply your own interface cable between the auxiliary port and the equipment you are connecting. For

console and auxiliary port pinouts, see the online Cisco 7401ASR Installation and Configuration Guide.

Gigabit Ethernet and Fast Ethernet Port Connections

The Cisco 7401ASR router has two native 10/100/1000-Mbps Ethernet interfaces. Each interface consists of two physical ports, an RJ-45 media port and a GBIC media port. The RJ-45 media ports provides 10/100-Mbps connectivity while the GBIC media ports provides 1000-Mbps connectivity.

Note The RJ-45 media is not capable of 1000 Mbps. This is only available via the Gigabit Ethernet GBIC media.

Note Any two of the four Ethernet ports may be used at the same time.
