Introduction

You have just purchased a cable 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 uses the cable television network to deliver high-speed data to your computer. Data is requested and sent over the cable television network at up to 38 megabits per second (Mbps). (Actual speeds will vary depending on your computer hardware, applications, the service offered by your cable service provider, and network traffic. This chapter explains how to prepare your computer system for cable modem installation.

Cable Modem Features

Your new cable modem has these features:

■ Cable line band wi dth a ll ows u ser d ata rat es of up to 3 8

megabits per second (Mbps) downstream,* faster than 56K analog modems, ISDN, or ADSL.

2 CHAPTER 1: BEFORE YOU BEGIN

■ You can use the Ethernet connection and USB

connection at the same time, allowing you to connect to the Internet using your computer and another Internet device at the same time.

■ 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 set up and

installation.

■ DOCSIS-compliance ensures interoperability with

DOCSIS-compliant cable suppliers.

■ 3Com’s extensive technical support organization

provides you with the quick answers you need to connect to the Internet.

* 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 cable 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

To use your cable modem, you first must have your service provider set up an Internet access account for you. Before contacting your cable provider to set up an account, have the following informa tion ha ndy:

■ The cable modem’s hardware revision, software

revision, Ethernet address, and USB address are located on a bar code sticker on the back of the cable modem. Write these numbers in the following blanks.

Contacting Your Local Cable Provider 3

■ Hardware revision: __________________

Software revision: __________________ Manufacturing date: __________________ Ethernet address: __________________ USB address: __________________

Now contact your local cable provider and verify this information:

1 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 cannot communicate with your cable company’s Internet access service. You should immediately consult your cable company and place of purchase to determine which 3Com cable modem to use. You can also visit the following URL for additional information:

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

2 Your cable provider has set up your cable Internet access

account. This Internet access account enables you to send and receive e-mail, access the World Wide Web, and receive other Internet services. This account must be set up before you can use your cable modem.

3 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 acce ss, 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 additiona l lin e fo r use wit h your cable mode m.

4 CHAPTER 1: BEFORE YOU BEGIN

Preparing Your Workspace

Before installing the cable modem you should prepare your workspace.

Before installing the modem:

■ Position your computer and cable modem so that they

are located near your cable outlet.

■ Allow plenty of r oom to guide th e cables away f r om the

cable modem without crimping them.

■ Allow for airflow around the cable modem.

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

the instructions on page 25 concerning stacki ng this cable modem with other 3Com OfficeConnect products.)

■ Ver ify that the temper ature in the room wher e the cable

modem will be operating is betwe en 0 and 40°C (32 and 104°F). Relative humidity must be between 5% and 95%, non-condensing.

■ Familiarize yourself with all of the materials supplied

with the cable modem. Please read these installation instructions thoroughly before installing the cable modem.

CAUTION: Your cable provider provides a cable connection. Do not attempt any rewiring without first contacting your cable provider.

It begins with “HBPK” followed by the last 6 digits of your Ethernet address. (The complete Ethernet address is located on the white sticker on the back of the cable modem.) If you need to call our customer support line, a representative will ask you for this serial number to help identify your cable modem.

Serial number: HBPK_________________

Before you begin installing the cable modem hardware, you need to determine how you would like to fit the cable modem into your work environment. There are three installation options:

■ Wall-mount installation (page 23)

■ Desktop installation ( page 24)

■ Stacking installation (page 25)

Connecting the Cabl e M od e m to Your Com p uter

Connect the cable modem to your computer and cable outlet before you install the cable modem software drivers. You can have the Ethernet cable and the USB cable connected to the cable modem and computer at the same time.

TIP: Before you unplug any computer cables, label them or make a sketch of how they are connected. This can be helpful when you plug them back in later.

CAUTION: To avoid risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged from electrica l outle t s.

NOTE: Refer to the illustration on page 26 while connecting the cable modem to your computer.
