How to Use this Guide
In addition to the documentation contained in the accompanying Firmware User’s Guide , this guide is designed
to get you up and running and connected to your local area network and the Internet. It is intended to be viewed
on-line, using the powerful features of the Adobe Acrobat Reader. The information display has been deliberately
designed to present the maximum information in the minimum space on your screen. You can keep this
document open while you perform any of the procedures described, and find useful information about the
procedure you are performing.
You can also print out all of the manual, or individual sections, if you prefer to work from hard copy rather than
on-line documentation. The pages are formatted to print on standard 8 1/2 by 11 inch paper. We recommend
that you print on 3-hole punched paper, so that you can put the pages in a binder for future reference.
This guide is organized into chapters describing the Netopia 3386-ENT’s advanced features. You may want to
read each chapter’s introductory section to familiarize yourself with the various features available.
Use the guide’s table of contents and index to locate informational topics.

This section tells you how to make the physical connections to your Netopia 3386-ENT Cable/DSL Router. This
section covers the following topics:
• “Find a Location” on page 2-1
• “What You Need” on page 2-1
• “Identify the Connectors and Attach the Cables” on page 2-3
• “Netopia 3386-ENT Cable/DSL Router Status Lights” on page 2-5
Find a Location
When choosing a location for the Netopia Cable/DSL Router, consider:
• Available space and ease of installation
• Physical layout of the building and how to best use the physical space available for connecting your Netopia
Cable/DSL Router to the LAN
• Available wiring and jacks
• Distance from the point of installation to the next device (length of cable or wall wiring)
• Ease of access to the front of the unit for configuration and monitoring
• Ease of access to the back of the unit for checking and changing cables
• Cable length and network size limitations when expanding networks
For small networks, install the Netopia 3386-ENT near one of the LANs. For large networks, you can install the
Netopia 3386-ENT in a wiring closet or a central network administration site.
WhatYou Need
Locate all items that you need for the installation.
Included in your router package are:
• The Netopia 3386-ENT Cable/DSL Router
• A power adapter and cord
• One Category 5 Ethernet cable
• One RJ-45 Modem cable
• The Netopia CD containing software and documentation

2-2 Getting Started Guide
You will need:
• A Windows–based PC or a Macintosh computer with Ethernet connectivity for configuring the Netopia
3386-ENT. This may be built-in Ethernet or an add-on card, with TCP/IP installed and configured. See
“Sharing the Connection” on page 4-1.
• A cable or DSL modem connected to a wall outlet wired for a connection to a telephone carrier who
supports either cable or Asymmetric Digital Subscriber Line (ADSL) connections.
Important Safety Instructions
CAUTION: Depending on the power supply provided with the product, either the direct plug-in power supply
blades, power supply cord plug or the appliance coupler serves as the main power disconnect. It is
important that the direct plug-in power supply, socket-outlet or appliance coupler be located so it is readily
accessible.
CAUTION (North America Only): For use only with a CSA Certified or UL Listed Limited Power Source or
Class 2 power supply, rated 12Vdc, 1.5A.
CAUTION (Europe Only): For use only with a GS approved Limited Power Source, rated 12Vdc, 1.5A.
TELECOMMUNICATION INSTALLATION CAUTIONS
When using your telephone equipment, basic safety precautions should always be followed to reduce the
risk of fire, electric shock and injury to persons, including the following:
1. Do not use this product near water, for example, near a bathtub, wash bowl, kitchen sink or laundry
tub, in a wet basement or near a swimming pool.
2. Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote
risk of electrical shock from lightning.
3. Do not use the telephone to report a gas leak in the vicinity of the leak.

Port Description
Modem port An RJ-45 jack labeled Modem to connect to the Ethernet port of your cable or DSL
modem.
Ethernet ports Four RJ-45 10/100Base-T Ethernet jacks. You can use one of these to configure the
Netopia 3386-ENT. You can either connect your computer directly to an Ethernet port
using the supplied Category 5 Ethernet cable, or connect both your computer and the
Netopia 3386-ENT to an existing LAN environment. The Ethernet ports are auto-sensing,
eliminating the need for a crossover cable.
Power port A DC power adapter cable connection.

2-4 Getting Started Guide
Connect your computer, DSL line, and power source as shown.
1. For a direct computer to router Ethernet connection, use the standard Ethernet cable included with your
router.
2. Use the supplied RJ-45 Modem cable to connect the router to your cable or DSL modem’s Ethernet port. Be
sure your cable or DSL modem is correctly installed according to its instructions.
3. Connect the supplied power brick to a power outlet and the connector end to the router.
You should now have: the power adapter plugged in; the Ethernet cable connected between the router and your
computer; and the Modem cable connected between the router and the cable or DSL modem. The cable or DSL
modem should be connected to its appropriate wall jack.
