Note to CATV system Installer- This reminder is provided to call the CATV systems

installer’s attention to Section 820-93 of the National Electrical Code, which

provides guidelines for proper grounding and in particular, species that coaxial

cable shield shall be connected to the grounding system of the building, as close

to the point of cable entry as practical.

1. Turn off and disconnect existing modems and routers.

If you are replacing a modem that is currently connected in your home,

unplug the modem and plug the new cable modem into the same outlet.

2. Use a coaxial cable to connect the cable port on the cable modem to a cable

wall outlet.

Make sure that the cable is tightly connected. We recommend that you

connect your cable modem directly to a cable wall outlet.

If you must share the connection, use a 3.5dB (1 to 2) splitter.

3. If you have Xnity Voice, connect your phone to the Tel 1 port

on the cable modem with the phone cable.

If you subscribed to two phone lines, connect the other phone to the Tel 2

port.

Note: The Tel 2 port only works for a two-phone line subscription.

4. Connect the power adapter to the cable modem and plug the power adapter

into an electrical outlet.

After 10 minutes, if the Online LED doesn’t light solid, make sure that the

cable outlet is working or call your Internet service provider (ISP) to make sure

you have service.

Note: When the Online LED lights solid, your cable modem is not connected

to the Internet yet. You must connect a router or computer to your cable

modem and then activate your cable modem with your cable Internet

provider.

port on the router
