What You Will Also Need
What You Will Also NeedWhat You Will Also Need
What You Will Also Need
In addition to the items packaged with your modem, you will need
the following items to complete your installation.
•Macintosh with an available Ethernet port and running Mac
OS 7.6.1 or above.
Note: If you have an older Mac, it may have an AAUI-15
Ethernet port rather than a 10BT Ethernet port. If so, you
will need to purchase an AAUI-15-to-10BT adapter.
•Cable modem service provided by your cable company. The
service must be DOCSIS (Data Over Cable Service Interface
Specification) compatible.
•A power outlet.
•A cable TV outlet that has been configured by your cable
company for high-speed broadband access.
•The proper length of 75-ohm coaxial cable to reach between
your cable modem and the cable outlet
Note: Because there is great variety in the way cable is installed,
we do not provide a coaxial cable to connect to your cable
system. If your cable service company does not provide
one, you should purchase a coaxial cable with an RG-59 or
RG-61U rating (75-ohm) and industry-standard F
connectors on both ends. For best performance, do not
use “push-on” F connectors; use only “screw-on” F
connectors.

Installing Your Cable Modem
This chapter explains how to connect your new cable modem to
your Macintosh and illustrates a typical cable installation in your
home or office.
Note: If your cable company provides you with an installation
procedure, follow it instead of the procedure described in
this chapter.
Installation consists of a few simple steps:
1

1Requesting cable modem service from your cable
company.

2Configuring your Macintosh's network settings.

3Connecting your modem.
Requesting Cable Modem Service
Requesting Cable Modem ServiceRequesting Cable Modem Service
Requesting Cable Modem Service
Before you install your cable modem, contact your cable company
to arrange for cable modem service and to establish an account.
A cable company representative may take care of the entire
installation for you, or you may get an installation CD from the
company and complete the procedure yourself. If you are doing it
yourself, you will need to provide the following information to the
cable company before you make the connections. We recommend
that you write the information down in the table below for future
reference. All the information you need is printed on the modem’s
bottom label, except for your Macintosh’s Ethernet Adapter MAC
(E-MAC) Address. The E-MAC Address is printed on the
Macintosh’s case, either on the side or bottom. If your Macintosh
is missing its E-MAC Address label, you can locate the number by
following the steps in the next section.

CAUTION •Locate the modem so that there is one inch of
free space between its top and sides and any
other device or the wall. This free space will
ensure proper air circulation. Do not block
the vents in any way. Failure to allow proper
air circulation can result in serious damage to
the cable modem.
•Do not place any items on top of the modem
while it is powered up.
•Do not place the modem near a heating or air
conditioning duct, in direct sunlight, or in a
location susceptible to drastic temperature
changes.
Follow the steps below to connect your modem. All connections
are made on the rear panel of the modem.
1
11
1Turn your Macintosh on.

22
2Connect one end of the 10BaseT/Ethernet cable to the 10BT
jack on the rear of the modem and the other end to the
Ethernet <…> jack on your Mac.
3
33
3Connect the coaxial cable to the cable TV jack on your wall.
Connect the other end of the cable to the cable connector on
the back of the modem.
4
44
4Insert the small round end of the power cord into the power
socket on the back of the modem. Plug the power adapter into
the wall socket. The READY and 10BT lights on the front
panel come on.
The cable modem now receives power and starts the
synchronization process as described below.

1 Installing Your Cable Modem 15
Automated Synchronization
Automated SynchronizationAutomated Synchronization
Automated Synchronization
The lights on the modem’s front panel indicate the status of the
synchronization process. After the modem completes a self-test, it
synchronizes with the cable provider network. During this process,
the SYNC light blinks, rapidly at first, then slowly. The ACT light
flickers briefly as the modem receives information from the cable
provider. When the process is complete, the SYNC light stays
steady On. For details on the front panel lights and their modes,
refer to Appendix A.
Note: When your modem receives power for the first time,
synchronization can take 20 seconds to five minutes.
This completes the installation of the modem. Please turn to the
next chapter, Using Your Cable Modem.
Tip:If you want to use your cable modem with more than one
Mac, please contact your cable service provider or Global
Village Sales at 800-631-3116.

Using Your Cable Modem
Once you've installed your cable modem, connecting to the
Internet is as simple as clicking the icon that corresponds to the
desired Internet application.
Note: At this time you may also want to install and use other
software, such as the value-added software included with
your Cable Modem CD or the software furnished by your
cable service provider. Refer to the CD(s) for installation
instructions.
Connecting to the Internet
Connecting to the InternetConnecting to the Internet
Connecting to the Internet
When you have correctly installed the cable modem, it
synchronizes itself with the cable network. The READY, 10BT,
and SYNC lights go on, indicating that the modem is fully
operational. To connect to the Internet, start your browser or other
Internet application.
Ending an Internet Session

Ending an Internet Session
After you have completed your Internet session, just close your
browser. The cable modem remains connected with the cable
system and stays ready to open another session.
Note: There is some risk associated with leaving your computer
and cable modem left on and unattended for long periods
of time. Security software, such as that included on your
Global Village CD, helps to protect your Mac in such
circumstances.

Unplugging the Modem
Unplugging the ModemUnplugging the Modem
Unplugging the Modem
If you unplug the cable modem or if power is lost for any reason,
all communication between the modem and the cable system is
terminated. When the power is restored, the modem must go
through the synchronization process before you can connect to the
Internet. This process takes place automatically when you turn the
modem on.
Note: If your cable TV service is interrupted, your cable modem
service may also be interrupted. Refer to the
Troubleshooting section of this manual for advice.

Troubleshooting Tips
This appendix provides tips for troubleshooting your cable modem
in the event of minor problems. In addition, check your modem
CD for FAQs, and our Website, www.globalvillage.com, for new
tips.
Q: I cannot access my Internet service or send or receive e-mail.
What should I do?
A: Check that the power is on and that the modem has completed
the synchronization process.
Check all physical connections. The READY, 10BT, and SYNC
lights on the modem's front panel must all be a steady green before
your cable modem will work.
Check to see that your cable TV service is working. If not, call your
cable service provider.
Verify that the MAC and Ethernet Adapter addresses you gave to
your service provider are correct, and that they are entered into
their system. (See page 7.)
Make sure you have given the proper cable modem name and
model number to your cable service provider. You will find this
information on the modem’s bottom case label.
Verify that your Ethernet card and port are working correctly.
Check that TCP/IP is configured correctly. Verify that the TCP/IP
parameters supplied by your cable company are correct and up-to-
date.

20 Global Village Cable Modem User’s Guide
Verify that your cable modem service is working.
If all else fails, you should reinstall the cable modem. If that fails,
please call Global Village Technical Support.
Q: Why does the power to my cable modem go on and off?
A: Check that you are using the power adapter that came with your
cable modem.
Q: The Cable Modem's SYNC light blinks for 5 minutes,
goes off, comes on again, and repeats.
A: Make sure the connection is secure.
Check with your cable service provider to make sure that high
speed access is available and running.
In rare instances, the cable signal may be weak or noisy. Be sure the
modem is attached to one of the ports on the first splitter after the
cable enters your home or office. Refer to the diagram below or
contact your cable provider.
