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 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

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
Preparing Your Works pace 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
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

USB INSTALLATION
2
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.

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

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 use one Internet protocol
(IP) address per cable modem.
Using the Ethernet port allows you to use a hub to connect
multiple computers to the cable modem, and you can use
multiple 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 2 “USB Installation” to set up the USB
connection.
