Connecting to a Management Console or Auxiliary Device

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 Routing Engine Interface Cable and Wire Specifications.

To connect a management console or auxiliary device:

1. Turn off the power to the console or auxiliary device.
2. Plug the female end (shown in Figure 45) of the provided serial cable into the appropriate CONSOLE or AUX/MODEM port. Figure 43 shows the external device ports on the craft interface. The upper ports connect to the Routing Engine in the upper Routing Engine slot (RE0), and the lower ports connect to the Routing Engine in the lower Routing Engine slot (RE1).
3. Using a 2.5-mm flat-blade screwdriver, tighten the screws on the connector.
4. Attach the other end of the cable to the console or auxiliary device.
