Connecting a Modem
When a modem is connected to the auxiliary port, a remote user can dial into the
router and configure it. You can use the light blue console cable that came in the
accessory kit. If you are using the light blue cable with the console port, you can
use any crossover RJ-45-to-RJ-45 cable.
Follow these steps to connect a modem to the router:
Connect one end of the cable to the black AUX port on the router rear panel.
Step 1
Connect the adapter labeled Modem to the other end of the cable.
Step 2
Connect the DB-25 end of the adapter to the modem.
