Chapter 3: Connecting the
Cable Modem to Your PC
Connecting Using the Ethernet Port
1. Make sure that you have TCP/IP installed on your computer. If you don’t
know what TCP/IP is or you don’t have it installed, refer to the section in
“Appendix B: Installing the TCP/IP Protocol.”
2. If you have an existing cable modem that you are replacing, disconnect it at
this time.
3. Connect the coaxial cable from your ISP/Cable Company to the Cable Port
on the back of the Cable Modem. The other end of the coaxial cable should
be connected in the manner proscribed by your ISP/Cable Company.
4. Connect a UTP CAT 5 (or better) Ethernet cable to the LAN Port on the back
of the Cable Modem. Connect the other end of the cable to the RJ-45 port
on your PC’s Ethernet adapter or your hub/switch/router.
5. With your PC turned off, connect the power adapter included in your pack-
age to the Power Port on the back of the Cable Modem. Plug the other end
of the power cord into a standard electrical wall socket. The Power LED on
the front of the Cable Modem should light up and remain on.
6. Contact your Cable ISP to activate your account. Usually, your Cable ISP
will need what is called a MAC Address for your Cable Modem in order to
set up your account. The 12-digit MAC address is printed on a bar code label
on the bottom of the Cable Modem. Once you have given them this number,
your Cable ISP should be able to activate your account.
The Hardware Installation is now complete.
Your Cable Modem is ready to use.
