Introduction

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 com prehensive 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 prepar e your computer system for cable modem installation.
* Actual speeds will vary depending on computer hardware, applications, service offered by your cable service provider, and network traffic.

BEFORE YOU BEGIN

Cable Modem Features

Cable line band wi dth a ll ows u ser d ata rat es of up to 3 8
megabits per second (Mbps)*, faster than 56K analog modems, ISDN, or ADSL.
Two-way design means that the cable modem both
sends and receives data over the cable line.
Plug-and-play USB 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
2 CHAPTER 1: BEFORE YOU BEGIN
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) the level of network traffic, which varies depending on when and where you go online.

Contacting Your Local Cable Service Provider

In order to use your cable modem, you need to set up an Internet access account with your local cable service provider.
Before contacting your provider to set up an account, have the following informa tion ha ndy:
The modem’s serial number. The serial number appears
on the white bar code label on the back of the modem
and consists of 10 characters preceded by the text
SN=. In the following example label image, the serial
number is 6LZ1377410.
Media Access Contr ol (MAC) ad dress. The MAC addr ess
appears on the white bar code label on the back of the
modem and consists of 12 characters preceded by the
text EA =. In the following example label image, the
MAC address is 00104B377410. Write both of these
numbers in the following blanks for future reference.
Serial number: SN= __________________
MAC address: EA = __________________
You should now contact your local cable service provider and verify that:
The cable service to your home supports two-way
cable modem access. If your cable service provider
does not provide two-way service, this modem will not

cable modem to use. You can also visit the following URL for additional information:
http://www.3com.com/cablemodem
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 service provider can install one. If you use your current cable line for cable television access, your cable service provider can also install an additional line for use with your cable modem.
Your cable service provider has set up your cable
Internet access account. Your cable service provider will set up an Inte rnet access account that wi ll allow you to send and recei ve e-mail, acc ess the Wo rld Wide Web, and receive other Internet services. This account must be set up before you can use your cable modem.

Preparing Your Workspace

Position your computer so that it is located near the
wall cable outlet.
Position the cable modem so that it is located near the
computer and the wall cable outlet. There should be plenty of room to guide the cables away from the modem without crimping them.
Do not restrict the airflow around the modem.
Ensure that the temperature in the room where the
cable modem will be operating is between 0 and 40°C (32 and 104°F). Relative humidity should be between 5% and 90%, non-condensing.
Familiarize yourself with all of the materials supplied
with the modem. Please read these i nstallation instructions thoroughly before installing the modem.

USB INSTALLATION

Deciding Which Installation Process to Use

The 3Com® HomeConnect™ cable modem allows you to connect to the Internet using either the USB port or the Ethernet port. Be sure to follow the instructions provided for the port that you want to use.
Using the USB port to connect to the Internet allows you to install the cable modem more quickly and easily than connecting to the Internet using the Ethernet port, because you do not need to install a network interface card (NIC). USB, however, only allows you to connect one computer to the cable modem.
Using the Ethernet port allows you to use a hub to connect multiple computers to the cable modem. To do this, you may need to obtain additional IP addresses from your cable service provider.
CAUTION: You cannot use the USB and Ethernet connections simultaneously. Therefore, you should not have the USB cable and the Ethernet cable plugged into the cable modem at the same time. Having the USB and Ethernet cables plugged into the cable modem at the same time might prevent you from accessing the Internet.
See Chapter 3 Ethernet Install ati on to set up the Ethernet connection.
