Connecting the Cable Modem

1 Power off the computer.
2 Use the illustration on page 35 as a guide to make the
following connections:
Connect the cable line to the cable modem's CATV
I
cable connector. Be careful not to bend the wire in
the center of the cable line when you connect it to
the cable modem. After hand-tightening the CATV
cable connector, use your adjustable wrench to
firmly tighten it. Be careful not to over-tighten the
connector or you may damage either the connector
or the cable modem. If you plan to have the cable
line connected to a television as well as to the cable
modem, you will need a cable line splitter (not
included).
Plug the cable modem's power adapter into a wall
I
outlet or surge protector and into the cable
modem's power jack.
Plug one end of the RJ-45 network cable into the
I
cable modem's Ethernet port and the other end into
the existing NIC.
3 Verify that the cable modem starts up and initializes
properly. When the cable modem is operating properly, the
cable modem Link Status and Power LEDs are lighted a
solid green.
If you are powering up the cable modem for the first time,
allow 15 minutes for this process to complete. See "Cable
