1BEFORE YOU BEGIN

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 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.

* Actual speeds will vary depending on computer

hardware, applications, service offered by your cable

service provider, and network traffic.

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 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

2CHAPTER 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 information handy:

■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 Control (MAC) address. The MAC address

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

Preparing Your Workspace 3

be able to communicate with your cable service

provider’s Internet access service. You should

immediately consult your cable service provider 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

■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

willset up 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 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 installation

instructions thoroughly before installing the modem.
