service and an Internet account with your cable provider.  
1
Note: If you’re connecting a single computer to the modem, you may use either the  
modem’s USB or Ethernet port. If you’re connecting more than one computer, you  
must use the Ethernet port combined with a Router.  
USB Connection  
If youre connecting the modem to one computer using the USB port, you must have:  
®
Windows 98 Second Edition, Me, 2000, or XP.  
An available USB port in the computer.  
A USB cable.  
Note: There is one USB cable in the box with the cable modem.  
Ethernet Connection  
If youre connecting the modem to one or more computers, for each computer you must have:  
An available RJ-45 Ethernet port (or adapter) either built-in or from a network  
interface card (NIC) installed on the PC.  
TCP/IP networking installed.  
®
®
Windows computers: Client for Microsoft Networks software installed.  
Note: TCP/IP and Client for Microsoft Networks is installed on most Windows  
computers. Please see Windows Help if you need help installing either on a  
Windows computer.  
A Category 5 (Cat 5) Ethernet patch cable.  
Note: There is one cable in the box with the cable modem.  
Additionally, if you want to connect more than one computer to the modem, you need:  
A Ethernet router, hub, or switch (for example, RP614 Cable/DSL Web Safe Router  
Gateway).  
Note: If using a hub or switch, you may need to get additional IP addresses from  
your ISP.

Install the Cable Modem  
After unpacking the box, you can install the cable modem. You do not have to power  
down any equipment to do this, but if you need to move your computer (perhaps to get  
to a port in the back), you may want to shut down the computer before moving it.
