INTRODUCTION
The Motorola CG3500 Communications Gateway cable modem enables you to connect your home or business computer to a
high-speed Data Over Cable Service Interface Specification (DOCSIS) 1.0 or 1.1 compliant data network. The CG3500 provides
high-speed, bi-directional data access with Radio Frequency (RF) downstream transfer rates up to 38 Mbps and RF upstream
rates up to 10 Mbps. It also provides telephony voice communication features using the Internet Protocol (IP) known as Voice
over IP (VoIP).
Unlike a dial-up modem, the CG3500 is always online. Just open your browser and surf.

Required to connect your computer to the CG3500.
Power supply and cable
The CG3500 is powered by an Uninterruptible Power Supply (UPS)
You need to purchase a 75-ohm coaxial cable with F-type connectors for connecting to the nearest cable outlet. If you have a
TV set attached to the cable outlet, you may need a 5-900 MHz splitter to use both the TV and the CG3500.
6
BEFORE YOU BEGIN
NOTE
The Ethernet card must be installed before the
CG3500. If it isn’t, follow the installation
instructions that came with your Ethernet card.
To use all the features of the CG3500, you will need the following:
Telephone(s)
with standard
RJ-11 connectors
Service Provider
Computer
Ethernet card
HTML Browser
Required to use the telephony features of the CG3500.

CG3500. Your computer must be configured for TCP/IP and
have an IP address for the CG3500 to operate. Your
Internet service provider furnishes the IP address.
Any standard HTML (web) browser works with the
CG3500.
®
, Macintosh®, and UNIX® operating systems.

INSTALLATION
NOTE
To turn on your CG3500, simply plug it in. It is
not necessary to unplug it when not in use.
Powering Up the First Time
You must allow 5 to 30 minutes to power up the first time because the
CG3500 must find and lock on the appropriate channels for communications.
1 Be sure that your computer is on and that the CG3500 is unplugged.
2 Plug in the AC power cord for the external UPS. Notice that the lights
on the front panel cycle through this sequence:
• Power flashes during a self-test. When the self-test is
successfully complete, the light is solid green.
• Receive flashes while the CG3500 scans for the downstream
channel. When the downstream channel is locked, the light is
solid green.
• Send flashes while the CG3500 scans for the upstream channel.
When the upstream channel is locked, the LED is solid green.
• Online flashes while the CG3500 is obtaining configuration
information. When the configuration information is obtained,
the LED is solid green.
During normal operation, the Power, Receive, Send, and Online lights are on
and the Activity light flashes.

INSTALLATION
Using the Optional Cradle
The CG3500 may come with an optional cradle that enables the modem to
stand vertically on a flat surface, such as a desktop. To use the cradle, insert
the modem into the cradle until the modem’s feet fully engage with the
grooves.

TROUBLESHOOTING
This information is to help you quickly solve a problem. Before calling your service provider, try pressing the reset button. Resetting
the CG3500 may take 5 to 30 minutes. Your service provider will need to know the status of the front-panel lights.
The problem Possible Solution
Green POWER light is off
Cannot receive or send data
Check that the power cord is properly plugged into the wall outlet and to the rear panel of the CG3500.
Call your service provider.
Check the lights on the front-panel. Note the first light from top to bottom that is off. This light
indicates where the error occurred. If the first light that is off is:
Receive
Send
Online
Check that your TV is working, that you have cable TV, and that you have a clear TV picture. If you
aren’t receiving your regular TV channels, your data service will not funct ion.
Check the coaxial cable at the rear panel and outlet and hand-tighten if necessary.
Check the IP address (follow the steps on page 17); call your service provider if you need an IP address.
During normal operation, the downstream channel is lost. During startup, the downstream
channel is not acquired.
During normal operation, the upstream channel is lost. During startup, the upstream
channel is not acquired.
During normal operations, the IP registration is lost. During startup, the IP registration was
not successful.
