Setting Up the Device
Before You Start
Local Cable Service
You will need to establish an account with your local cable operator in order to access the Internet with this
modem. They will assist you in setting up the modem to operate on their network.
Then for your modem to communicate with the cable service, you will first need to be able to identify the cable
modem. The Cable Media Access Control (CMAC) address is a unique number that is used for the purpose of
identifying the modem on the network. The CMAC address is found on the rear panel of the modem. You may be
required to provide this information to your cable service operator. For convenient reference you can write the
CMAC address in the space provided below.
