Getting Started  
Contacting Your Local Cable Service Provider  
You must also give your cable service provider  
the following information:  
You need to set up an Internet access account with  
your local cable service provider in order to use  
your cable modem. When you contact your cable  
service provider, verify the following conditions:  
• The serial number of the modem  
• The Media Access Control (MAC) address of  
the modem  
• The cable service to your home supports  
two-way, Euro-DOCSIS-compatible cable  
modem access. If your cable company does not  
provide two-way Euro-DOCSIS-compatible  
service, this modem will not be able to  
communicate with your cable service  
providers Internet access service.  
These numbers appear on a white bar  
code label located on the side of the  
cable modem. The serial number consists of  
a series of alpha-numeric characters located  
directly under the SER. NO. bar code. The  
MAC address consists of a series of  
alpha-numeric characters located directly  
under the MAC bar code. The following  
example illustrates a sample bar code label.  
• You have an active RF coaxial cable line near  
your personal computer (PC), and is it capable  
of two-way cable modem service. If your  
current cable input is not conveniently located  
near your PC, your cable service provider can  
install one.
