Key Item

Description
The Ethernet port provides a connection to Ethernet equipped computers using a cable terminated with an RJ-45 connector. The adjacent lights are: 10 On if there is a 10Base-T Ethernet connection. It flashes during data transfer. 100 On if there is a 100Base-T Ethernet connection. It flashes during data transfer.
The USB port provides a connection to USB equipped computers. If you experience a problem, you can push this recessed button to reset the cable modem (see Troubleshooting on page 35). Resetting may take 5 to 30 minutes because the cable modem must find and lock on the appropriate communications channels. The CABLE port provides a connection to the coaxial cable (coax) outlet.

POWER The POWER connector provides power to the cable modem.
Before you begin the installation, check that you received the following items with your SURFboard cable modem:
Power cord 10/100Base-T Ethernet cable USB cable SURFboard Cable Modem CD-ROM
Connects the SURFboard cable modem to the AC electrical outlet Connects to the Ethernet port Connects to the USB port Contains the User Guide and USB drivers
You will need 75-ohm coaxial cable (coax) with F-type connectors to connect your cable modem to the nearest cable outlet. If a TV is connected to the cable outlet, you may need a 5-900 MHz RF splitter and two additional coaxial cables to use both the TV and the cable modem. The coaxial cable and RF splitter are available at consumer electronic stores. To connect your SB4220 to an Ethernet hub as described in Cabling for Multiple Users on page 33, you may need a crossover cable. Check the documentation provided with your hub.

Precautions

To avoid damaging your cable modem or PC with static electricity: Postpone cable modem installation until there is no risk of thunderstorm or lightning activity in the area. To avoid damaging the cable modem with static electricity:
Always make the wall connection first.
Always first connect the coaxial cable to the grounded cable TV wall outlet. Before you connect or disconnect the USB or Ethernet cable from your cable modem or PC, always touch the coaxial cable connector on the cable modem to release any static charges.
To prevent overheating the cable modem, do not block the ventilation holes on its sides. Do not open the cable modem. Refer all service to your cable service provider. Wipe the cable modem with a clean, dry cloth. Never use cleaning fluid or similar chemicals. Do not spray cleaners directly on the unit or use forced air to remove dust.
Before you connect or disconnect the USB or Ethernet cable, always touch the coaxial cable connector on the cable modem.

Signing Up for Service

You must sign up with a cable service provider to access the Internet and other online services. To activate your service, call your local cable service provider. You need to provide the MAC address printed on the bar code label marked HFC MAC ID on the rear panel. You can record your cable modem MAC address here: 00 : ______ : ______ : ______ : ______ : ______ You should ask your cable service provider the following questions:

Do you have any special system requirements? When can I begin to use my cable modem? Are there any files I need to download after I am connected? Do I need a user name or password to access the Internet or use e-mail?
Computer System Requirements
You can use any web browser such as Microsoft Internet Explorer or Netscape Navigator with your SURFboard cable modem. For Microsoft Windows computers, the Installation Assistant application automatically checks your system configuration.

For information about customer service, technical support, or warranty claims, see the Software License and Warranty Information card provided with your SURFboard cable modem. For answers to typical questions, see Frequently Asked Questions on page 55. For information about Motorola consumer cable products, education, and support, visit http://www.motorola.com/broadband.

Here are answers to questions our customers frequently ask.
What is high-speed cable Internet access? Cable Internet access uses cable television wires instead of telephone lines to connect to the Internet. It is extremely fast and affordable and does not tie up telephone lines for incoming or outgoing calls and faxes. How fast are cable modems? Cable modems offer Internet access at speeds up to 100 times faster than a traditional phone modem. You can experience speeds of over 1,000 Kbps. Due to network condition such as traffic volume and the speed of the sites you visit, actual speed may vary. Many network and other factors can affect download speeds. Can I still watch cable TV while using my cable modem? Yes, your cable TV line can carry the TV signal while you send and receive information on the Internet. What are CableLabs Certified, DOCSIS and Euro-DOCSIS? CableLabs Certified, DOCSIS, and Euro-DOCSIS are the industry standards for high-speed data distribution over cable television system networks. They are intended to ensure that all compliant cable modems interface with all compliant cable systems. Your Motorola SURFboard cable modem is DOCSIS or Euro-DOCSIS certified.

Q A Q A

If I have a cable modem, can I still use my old 28.8 Kbps or 56 Kbps modem? Yes! Although once youve experienced the speed of cable Internet access, youll never again want to wait for traditional dial-up services. I have more than one computer. Do I need more than one SURFboard cable modem? No, not if your computers are connected on a network. The SURFboard cable modem supports current Internet connection sharing technologies to enable you to connect up to 32 PCs to the Internet using a single cable modem. Do I need to change my Internet service provider (ISP)? Currently, most Internet service providers do not provide cable Internet access. Contact your cable company for your specific information. Do I need to subscribe to cable TV to get cable Internet access? No, but you will need to subscribe to cable Internet service. Some systems require that you subscribe to basic service before you can get Internet access and/or offer a discount when you use your own cable modem. Check with your local cable company for specific information. What type of technical support is available? For questions about your Internet service, connection, or cable modem, call your cable service provider. What do I do if my SURFboard cable modem stops working? Troubleshooting on page 35 provides tips to diagnose problems and simple solutions. If you continue to have problems, call your cable service provider.
