The General Instrument® SURFboard® SB3100 cable modem enables you to
connect your home or business computer to a DOCSIS-compliant data
network. It provides high-speed access to the Internet and other online
services. The SB3100 transmits and receives data at much higher speeds than
traditional telephone or ISDN modems.
Unlike a telephone modem, the SB3100 is always online. Just open your
browser and surf.

Before you begin the installation, check that you received:
Power cord
Required to connect the SB3100 to the
electrical outlet.
One 10Base-T Ethernet cable
Required to connect your computer to the
SB3100.
You need to purchase a 75-ohm coaxial cable with F-type connectors for
connecting your SB3100 to the nearest cable outlet. If you have a TV set
attached to the cable outlet, you may need a 5-900 MHz splitter to use both
the TV and the SB3100.

To use the SB3100 with your computer system, you need the following:
Service Provider
You must sign up with your data service provider who
provides access to the Internet and other online services.
Computer
Your computer must support Ethernet and the TCP/IP
protocol to access the SB3100. The SB3100 is compatible
with Microsoft
®
, Macintosh®, and UNIX® operating systems.
You don’t need special software to operate the SB3100.
Ethernet card
Any standard 10Base-T Ethernet card operates with the
SB3100. Your computer must be configured for TCP/IP and
have an IP address for the SB3100 to operate. Your service
provider furnishes the IP address.
HTML Browser
Any standard HTML (web) browser works with the SB3100.

You must call your service provider to activate your service. You need to
provide the media access control (MAC) address. This address is found on
the barcode label marked HFC MAC ID on the rear panel. The address
format is 00:20:40:xx:xx:xx.
The installation of the SB3100 can be completed in a matter of minutes.
After you attach the three cables, you must configure your computer.
For a Single User
1
Connect the coaxial TV cable to the SB3100 connector marked
CABLE and the other end to the cable outlet or splitter. Hand-tighten
the connectors to avoid damaging them. You may need a 5-900 MHz
splitter if you have a TV connected to the cable outlet.
2 Connect the 10Base-T Ethernet cable to the SB3100 connector
marked ENET and the other end to the Ethernet jack on the back of
your computer.
3 Plug the power cord into the SB3100 connector marked POWER and
the other end to the electrical outlet.

For Multiple Users
The SB3100 can easily serve as a gateway to the Internet for up to 32 users.
The users must be on the LAN and the SB3100 must be attached to the
LAN and the cable system.
The network administrator at your service provider configures your modem
for multiple users.

Powering Up the First Time
You must allow 5 to 30 minutes to power up the first time because the
SB3100 must find and lock on the appropriate channels for communications.
1 Be sure that your computer is on and SB3100 is unplugged.
2 Plug the SB3100 in and notice that the lights on the front panel cycle
through this sequence:
• Power flashes during a self-test. When the self-test is successfully
complete, the light is solid green.
• Receive flashes while the SB3100 scans for the downstream
channel. When the downstream channel is locked, the light is
solid green.
• Send flashes while the SB3100 scans for the upstream channel.
When the upstream channel is locked, the LED is solid green.
• Online flashes while the SB3100 is obtaining configuration
information. When the configuration information is obtained, the
LED is solid green.
During normal operation, the Power, Receive, Send, and Online lights are on
and the Activity light flashes.

The SB3100 contains all necessary software. You don’t need to configure the
SB3100 but you must configure your computer for TCP/IP and check for an
IP address. Your service provider may provide additional instructions for
setting up your computer. The following basic instructions are for
Windows™ 95 or Windows 98. If you are using a different operating
system, refer to that user guide.
Configuring for TCP/IP
1
On the Windows Desktop, click Start.
2 Select Settings and then Control Panel from the pop-up menus.
3 Double-click the Network icon on the Control Panel window.
4 Select the Configuration tab on the Network window.
5 Check to see if TCP/IP has been installed for the Ethernet card. If
TCP/IP appears in the list of network components, it is installed and
you can proceed to step 10. If it doesn’t appear on the list, continue
with step 6.

Verifying Your IP Address
The following basic instructions are for Windows 95 or Windows 98. If you
are using a different operating system, refer to that user guide. To check the
IP address:
1 On the Windows Desktop, click Start.
2 Select Run.
3 Type winipcfg.exe. A window similar to the example is displayed.
4 Select your adapter name.
5 Click Renew.
6 Click OK after the system displays an IP address.
If after performing this procedure, your computer doesn’t access the
internet, call your service provider. They will assist in verifying your
configuration.

Check that the power cord is properly plugged into the wall outlet and the rear panel of the SB3100.
Call your service provider.
Check the lights on the front-panel. Note the first light from top to bottom that is off. This light
indicates where the error occurred. If the first light that is off is:
Receive
Send
Online
During normal operation, the downstream channel is lost. During startup, the downstream
channel is not acquired.
During normal operation, the upstream channel is lost. During startup, the upstream
channel is not acquired.
During normal operations, the IP registration is lost. During startup, the IP registration was
not successful.
Check that your TV is working if you have cable TV and you have a clear TV picture. If you aren’t
receiving your regular TV channels, your data service will not function.
Check the coaxial cable at the rear panel and outlet and hand-tighten if necessary.
Check the IP address (follow the steps on page 13); call your service provider if you need an IP address.
