1BEFORE YOU BEGIN

Introduction Congratulations! You have just purchased a modem which features a

pioneering new technology. 3Com, the leader in networking and data

access, is proud to offer you this technology that makes Internet access

possible at speeds previously only imagined!

This internal cable modem is one part of a comprehensive

communications system that utilizes the cable television network to

deliver high-speed data to your computer. Data is requested via your

phone line and sent from the Internet via the cable network to your

computer at burst rates of up to 38 Mbps*!

* Actual speeds will vary depending on computer hardware, applications,

service offered by your Broadband Service Provider, and network traffic.

NOTE: If the information in the release notes shipped with your product

differs from the information in this guide, follow the instructions in the

release notes.

Conventions The following table lists the conventions used within this manual.

Icon Notice Type Description

Information note Important features or instructions

Caution Information to alert you to potential damage to a

program, system, or device

Warning Information to alert you to potential personal injury

1-2 CHAPTER 1: BEFORE YOU BEGIN

Cable Modem

Features

■DOCSIS compatibility ensures interoperability with cable operators.

■You can achieve data transfer burst rates up to 38 Mbps.

■Local and remote diagnostic capabilities ensure troubleshooting ease.

■The modem’s design allows for easy software updates.

■3Com’s extensive end-user technical support provides quick solutions

to your problems.

Contacting Your

Local Cable

Company

In order to use your cable modem, you need to establish an Internet

access account with your local cable company. Before contacting your

cable company to establish an account, have the following information

handy:

■The modem’s Media Access Control (MAC) address, which is located

on a bar code sticker on the modem (see the following image). The

MAC address is a 12-character number beginning with 00C049. Write

the MAC address in the blank provided here:

MAC address: 00C049__________

■The modem’s model number. The modem’s model number is located

on the circuit board itself and begins with 1.012 (see the following

image). Write the model number in the blank provided here:

Model number:_____________

Preparing Your Workspace 1-3

You should now contact your local cable company and verify the

following:

■The cable service to your home should support one-way (or “telco

return”) cable modem access. If your cable company does not provide

one-way service, the 3Com HomeConnect Cable Modem will not be

able to communicate with your cable company’s Internet access

service. You should immediately consult your cable company and

place of purchase to determine the proper 3Com cable modem to use.

You can also visit the following URL for additional information:

http://www.3com.com/cablemodem

■Your cable provider should set up your cable Internet access account.

Your cable provider will setup an Internet access account that will

allow you to send and receive e-mail, access the World Wide Web,

and receive other Internet services. This account must be setup before

you can use your cable modem.

■Your cable company may also provide you with a login name and

password for your cable modem Internet access account. Write these

in the blanks below for future reference:

Password: ______________________

Preparing Your

Workspace

■Position your computer so that it is located near the cable access

outlet and a telephone wall jack.

■Familiarize yourself with all of the materials in this box.

1-4 CHAPTER 1: BEFORE YOU BEGIN

■Please read these installation instructions thoroughly before installing

your cable modem.

■If you use your current cable line for cable television access, your cable

company can also install an additional line for use with your cable

modem.

CAUTION: Your cable company will provide a cable connection. Do not

attempt any rewiring without first contacting your cable company.
