provider.
2. Open a web browser of your choice, such as Internet Explorer, Firefox, or
Google Chrome, or Safari.
3. Type a valid URL (for example, www.arrisi.com/consumer) in the

- If it did not open, please contact your current service provider to set up
your Internet service or activate your modem.

the modem label on the bottom of your SB6121 (see back page for details).
Before starting, make sure your cable service is up and running, and that
the coaxial cable is already connected to your home’s cable outlet. If not,
contact your service provider.

outlet) to the Cable connector on the rear of your SB6121.
Use your hand to tighten each connector.
