Connecting to the Auxiliary Port

When a modem is connected to the auxiliary port, a remote user can dial in to the router and configure it. Use the light blue console cable and the DB-9-to-DB-25 connector adapter that came in the router accessory kit.

To connect a modem to the router, follow these steps.

Procedure

Step 1 Connect the RJ-45 end of the adapter cable to the black AUX port on the router. See Figure 4-13.
