Introduction

Congratulations! You have just purchased a modem

featuring a pioneering new technology, making Internet

access possible at speeds previously only imagined! This

external 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 and sent over the cable television network at

burst rates of up to 38 megabits per second (Mbps). This

chapter explains how to prepare your computer system for

cable modem installation.

Conventions

The following table lists the conventions used within this

manual.

Cable Modem Features

■

Cable line bandwidth allows user data rates of up to 38

megabits per second (Mbps)*, faster than 56K analog

modems, ISDN, or ADSL

■

Two-way design means that the cable modem sends

and receives data over the cable line (unlike one-way

cable modems, which require an analog modem for

upstream data)

■

Plug and play operation ensures easy setup and

installation

■

DOCSIS-compliance ensures interoperability with cable

suppliers

■

3Com’s extensive technical support organization

provides you with the quick answers you need to get up

and running

* NOTE: Please note that the following factors affect the

speeds you may experience: (1) your computer equipment

and configuration, including the speed of your processor,

the amount of RAM on your system, and your available

hard disk space; (2) applications running simultaneously

with the modem which use varying amounts of your

computer’s resources; (3) the capacity of the Internet

service you order from your provider; (4) changing network

traffic levels depending when you go online.

Contacting Your Local Cable Provider

In order to use your cable modem, you need to setup an

Internet access account with your local cable provider.

Before contacting your cable provider to setup an account,

have the following information handy:

■

The modem’s hardware revision, software revision,

Ethernet address, and USB address are located on a bar

code sticker on the back of the modem. Write these

numbers in the following blanks.

■

Hardware revision: __________________

Software revision: __________________

Manufacuring date: __________________

Ethernet address: __________________

USB address: __________________

Preparing Your Workspace

You should now contact your local cable provider and verify

the following:

■

The cable service to your home supports two-way cable

modem access. If your cable company does not provide

two-way service, this 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 has 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.

■

You have a cable line near your PC and it has been

prepared for cable modem service. If you do not have a

cable line in your home that supports two-way cable

modem access, or if your current cable connection is

not conveniently located near your computer, your

cable provider can install one. 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.

Preparing Your Workspace

■

Position your computer so that it is located near your

cable outlet.

■

The cable modem should be located near your

computer and the cable outlet. There should be plenty

of room to guide the cables away from the modem

without crimping them.

■

Airflow around the modem should not be restricted.

■

Do not stack anything on top of the cable modem. (See

the instructions on page 14 concerning stacking this

modem with other 3Com OfficeConnect

products.)

HAPTER

1: B

EFORE

EGIN

■

The temperature in the room where the cable modem

will be operating should be between 0 and 40°C (32

and 104°F). Relative humidity should be between 5%

and 95%, non-condensing.

■

Familiarize yourself with all of the materials supplied

with the modem. Please read these installation

instructions thoroughly before installing the modem.

CAUTION: Your cable provider will provide a cable

connection. Do not attempt any rewiring without first

contacting your cable provider.
