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.
2. Connect the Ethernet cable to the Ethernet port on your computer (or
other device) and to the Ethernet port on the rear of your SB6121.

Testing the Modem Connection
1. Power ON your computer and log in. The RECEIVE, SEND, and
ONLINE LEDs on your modem should first FLASH (blink) and then light
up SOLID. See next page for more LED information.
Note: If all three LEDs did not light up SOLID, contact your service
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
address bar and then click or press Enter. The website should open.
- If it opened, your modem was set up properly.

your Internet service or activate your modem.
