Introduction
Congratulations, you have a new Motorola® SURFboard® cable modem. It provides
high-speed access to the Internet and other online services. This cable modem transmits
and receives data much faster than traditional dial-up or ISDN modems. Unlike a dial-up
modem, your cable modem is always online. Just open your browser and surf!
You can use your high-speed, upgradeable cable modem to connect one or more
computers in your home or business to the Internet. You can connect:
• A single computer equipped with a Universal Serial Bus (USB) port directly to the
USB port on the SURFboard cable modem
• A single computer equipped with an Ethernet adapter directly to the Ethernet port on
the SURFboard cable modem
• Two computers; one to the USB port and one to the Ethernet port
• Up to 63 computers to a single SURFboard cable modem using an Ethernet hub as
shown in “Cabling for Multiple Users” on page 40
Easier!
Unlike dial-up modems or ISDN, you’re always on,
always connected. For easiest set-up, use the
Installation Assistant on the SURFboard Cable
Modem CD-ROM.
Faster!
Your cable modem is up to 100 times faster than a
dial-up modem. It lets you enjoy surfing the Web
without the long wait. Because many network and
other factors can affect performance, the actual
speed will vary.
Better!
Your cable modem is made by the company with
over 50 years of cable TV expertise.

Cabling and Startup for a Single User
Allow 5 to 30 minutes to power up the first time because the SURFboard cable modem
must find and lock on the appropriate channels for communications.
1Be sure your computer is on and the cable modem is unplugged.
2Connect one end of the coaxial cable to the cable outlet or splitter. Connect the
other end of the coaxial cable to the CABLE connector on the cable modem.
Hand-tighten the connectors to avoid damaging them.
3Insert the SURFboard Cable Modem CD-ROM into your CD-ROM drive.
4Plug the power cord into the +12VDC connector on the cable modem and the
electrical outlet. This turns the SURFboard cable modem on. You do not need to
unplug it when not in use.
5Check that the lights on the cable modem front cycle through this sequence:
• Power flashes during the self-test and changes to solid green when the self-test
is successfully complete.
• Receive flashes while scanning for the receive (downstream) channel and
changes to solid green when it is connected.
• Send flashes while scanning for the send (upstream) channel and changes to
solid green when it is connected.
• Online flashes while the cable modem downloads configuration data and
changes to solid green when the download is complete.
