Replace the Console or Auxiliary Cable

To use a system console to configure and manage the Routing Engine, connect it to the appropriate CONSOLE port on the craft interface. To use a laptop, modem, or other auxiliary device, connect it to the appropriate AUX/MODEM port on the craft interface. Both ports accept an RS-232 (EIA-232) serial cable with DB-9/DB-9 connectors. One such cable is provided with the router. If you want to connect a device to both ports, you must supply another cable. For cable specifications, see Cable Specifications for Routing Engine Management Interfaces.

To connect a management console or auxiliary device, follow this procedure:

1. If a cable is already installed in the CONSOLE or AUX/MODEM port, perform the following steps:
   1. Turn off the power to the console or auxiliary device.
   2. Unscrew the screws that secure the cable connector to the port, using a 2.5-mm flat-blade screwdriver if necessary.
   3. Pull the cable connector straight out of the port.
   4. Disconnect the cable from the console or auxiliary device.
2. Plug the female end of the replacement serial cable into the appropriate CONSOLE or AUX/MODEM port. Figure 44 shows the external device ports on the craft interface.
3. Tighten the screws on the connector, using a 2.5-mm flat-blade screwdriver if necessary.
4. Power on the auxiliary or console device.
