Install the Cable Modem

WARNING:

To prevent possible damage to equipment, disconnect any other telephone service before connecting your cable modem to the same wires.

Hazardous electrical voltages can exist on the telephone, Ethernet, or coax cable wiring. Be sure to disconnect AC power from all devices while installing your service.

All wiring and connections must be properly insulated to prevent electrical shock.

Telephone connections to an installed home telephone wiring network should be done by a qualified installer. The cable telephone service provider may offer professional installation and connection to the home telephone wiring network. A fee may be charged for this service.

2Power off your PC and other networking device; then, unplug them from the power source.

3Connect the active RF coaxial cable from your service provider to the coax connector labeled CABLE on the back of the cable modem.

Note: To connect a TV, DHCT, set-top, or VCR from the same cable connection, you will need to install a cable signal splitter (not included). Always check with your service provider before using a splitter as a splitter may degrade the signal.

4Connect your PC to the cable modem by connecting one end of the yellow Ethernet cable to the Ethernet port on your PC, and the other end to the yellow ETHERNET port on the back of the cable modem.

Note: To install more than one Ethernet device on a cable modem that has only one Ethernet port, use an external multi-port Ethernet switch(s) or cable router (not provided).

5If your cable modem supports digital telephone service (VoIP), connect one end of a telephone jumper cable (not included) to a telephone outlet in your home or to a telephone or fax machine. Then connect the other end of the jumper cable to the appropriate RJ-11 TELEPHONE port on the back of the cable modem. The telephone ports are light gray and are labeled 1/2 and 2 or 1 and 2 depending on the region of the world the cable modem is used.

Notes:

–Make sure to connect your telephone service to the correct RJ-11 port. For single line telephone service, connect to port 1/2 or 1.

–In North America, cable modems have multi-line capability on the RJ-11 telephone port labeled 1/2. Line 1 is on pins 3 and 4 of port 1/2, and Line 2 is supported on pins 2 and 5. In Europe, cable modems support only one line per port. Line 1 is on port 1 and line 2 is on port 2.

–Telephones that require electrical connectors other than RJ-11 may require an external adapter (sold separately).
