Getting Started
Your Zoom™ Ethernet (10/100BaseT) cable modem is
designed to connect your personal computer to the Internet
through the same cable that you use for television reception.
Contacting Your Cable Company
Please fill out the information in the following table before you
begin installing your Zoom cable modem. Your cable service pro-
vider needs this information to ensure that your modem connects
to the Internet successfully. Note: This manual assumes that you
have already arranged for cable modem service and established a
cable modem account with your cable company.
Important Installation Information
The following information is located on the label on the bottom of your
modem. You will be asked to provide it when you call for installation.
Product Name: Zoom CableModem

You Will Also Need
To complete your installation, you must have these items:
•Cable modem service provided by your cable company. The
service must be DOCSIS- (Data Over Cable Service Interface
Specification) or EuroDOCSIS-compatible, where applicable.
•A computer running the Windows®95, 98, NT 4.0, 2000, Mil-
lennium (Me), XP, or Linux operating system, or a Macintosh®
running System 7.5 or later.
•An Ethernet (10BaseT or 100BaseT) port in the computer you
want connected to your cable modem. If your computer
doesn’t have an Ethernet port, you will need to buy a Network
Interface Card (NIC) and install it before completing the cable
modem setup. Some cable operators offer the option of pro-
viding and installing the NIC card.
•A power outlet.
•A 75-ohm coaxial cable that will connect to the cable TV sys-
tem and that can reach to where you intend to place your cable
modem.
Note: Because there is great variety in the way cable is installed,
Zoom does not provide a coaxial cable to connect your
modem to your cable system. Your cable company may
provide the appropriate length cable for your use. If the
company doesn’t supply the cable, you should buy a coax-
ial cable with an RG-59 or RG-61U rating (75 ohm) and
industry-standard F connectors.
Tip: For best performance, do not use “push-on” F con-
nectors; use only “screw-on” F connectors.

Tips:
✔If you are using the mounting stand and find that the modem
is top heavy with the coaxial cable connection on top, turn the
modem over so that the coaxial cable connection is on the
bottom.
✔Your service provider may advise you that a splitter, amplifier,
and high-pass filter are required. The Troubleshooting ap-
pendix includes a diagram illustrating such a setup (page 28).

CAUTION: Place the modem so that there is one inch of free
space between its top and sides and any other de-
vice or the wall. Do not block the vents in any way.
Failure to allow proper air circulation can result in
serious damage to the modem.
Do not place any items on top of the modem while
it is on.
Do not place the modem near a heating or air con-
ditioning duct, in direct sunlight, or anywhere sus-
ceptible to drastic temperature changes.
1Plug one end of the Ethernet cable into the Ethernet jack on
the rear of the modem and the other into the Ethernet jack on
your computer.
2•If you have a wall outlet cable jack, connect one end of the
coaxial cable to it. Connect the other end of the cable to
the Cable connector on the back of the cable modem.
•If you don’t have a wall jack, you should have a length of
coaxial cable entering your house close to where you want
to locate your cable modem. Connect the end of this cable
to the Cable connector on the back of the modem.
3Connect the power cord. Insert the small round end of the
power cord into the Power socket on the back of the cable
modem. Plug the power adapter into the wall socket.

The Modem’s Power-Up Process
As your cable modem powers itself up, the lights on the front
panel indicate the different stages. When the modem initially pow-
ers itself up, the PWR light comes on. After completing a self-test,
the cable modem registers with the cable system. While the modem
is searching for and registering with the cable system, the SYNC
light blinks: At first the light blinks fast; then it blinks slowly. After
the process is complete, the SYNC light stays on steady. (The table
on page 6 lists the LEDs and their modes.)
Note: It may take several minutes for the modem to register with
the cable system.
After the cable modem is connected, the 10BT light comes on.
This indicates that the cable modem and the computer’s data inter-
face are linked.
If you do not see the 10BT light on, double-check to see that the
Ethernet cable is securely inserted in the proper jacks on the cable
modem and computer. The PWR light must be on before the
10BT light will come on.
Note: If you experience an outage with your cable TV service,
your cable data connection will most likely also be off. If
you are unable to connect to the Internet, or if your
browser notes that it is unable to find a selected URL,
check to ensure that you have cable TV service available.
If not, contact your cable service provider.
At this point, the system at your cable company will communicate
with the modem and computer to finalize the installation. This part
of the installation varies from company to company, so you should
follow the directions that are given to you.
In some cases, the cable company will automatically query the cable
modem via the cable connection. In other cases, your cable com-
pany may have instructed you to phone back with your cable mo-
dem’s MAC address once you completed the hardware installation.
The cable company may need the cable modem’s MAC addresses
(located on your cable modem’s label), or request billing informa-
tion. Refer to the table on page 1.

The Zoom CM Monitor Utility
The Zoom CM Monitor Utility works with Windows
98/2000/Me/XP computers. It is automatically installed when you
install the cable modem software.
The utility is intended for both end users and cable service provid-
ers. It is meant to eliminate or decrease the number of cable com-
pany “truck rolls” and to save subscribers and service providers
time and money.
For end users installing the modem themselves, should a question
arise pertaining to the installation, the application can help during a
call to the cable company.
