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 3387W-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.

Important Safety Instructions
POWER SUPPLY INSTALLATION
Connect the power supply cord to the power jack on the Cayman Router. Plug the power supply into an
appropriate electrical outlet.
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.
(Sweden) Apparaten skall anslutas till jordat uttag när den ansluts till ett nätverk
(Norway) Apparatet må kun tilkoples jordet stikkontakt.
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.

Ethernet ports Four RJ-45 10/100Base-T Ethernet jacks. You can use one of these to configure the
Netopia 3387W-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 3387W-ENT to an existing LAN environment. The Ethernet ports are
auto-sensing, eliminating the need for a crossover cable.

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.
4. Each computer using the wireless network requires its own Wi-Fi CERTIFIED™ 802.11b adapter to be
installed in the computer.
This may be purchased from any Wi-Fi CERTIFIED™ manufacturer for your particular computer.
You should now have: the power adapter plugged in; the Ethernet cable connected between the router and your
computer; and the telephone cable connected to its appropriate wall jack.

This chapter describes how to physically connect the Netopia 3387W-ENT to your local area network (LAN).
Before you proceed, make sure the Netopia 3387W-ENT is properly configured. You can customize the router’s
configuration for your particular LAN requirements using console-based management (see “Telnet-Based
Management” on page 5-1).
This section covers the following topics:
•“Readying Computers on Your Local Network” on page 3-1
•“Connecting to an Ethernet Network” on page 3-2
Readying Computers onYour Local Network
PC and Macintosh computers must have certain components installed before they can communicate through
the Netopia 3387W-ENT. The following illustration shows the minimal requirements for a typical PC or
Macintosh computer.
Application software: This is the software you use to send e-mail, browse the World Wide Web, read
newsgroups, etc. These applications may require some configuration. Examples include the Eudora e-mail client
and the Web browsers Microsoft Internet Explorer and Netscape Navigator.
TCP/IP stack: This is the software that lets your PC or Macintosh computer communicate using Internet
protocols. TCP/IP stacks must be configured with some of the same information you used to configure the
Netopia 3387W-ENT. There are a number of TCP/IP stacks available for PC computers. Windows 95 includes a
built-in TCP/IP stack. Macintosh computers use either MacTCP or Open Transport. See “Configuring TCP/IP on
Windows-based Computers” on page 4-5. Macintosh computers use either MacTCP or Open Transport. See
“Configuring TCP/IP on Macintosh Computers” on page 4-7.

3-4 Getting Started Guide
The Netopia 3387W-ENT in an 802.11b wireless network
To create your 802.11b wireless network
you must install a Wi-Fi CERTIFIED™
wireless adapter card in each computer
that will join the wireless LAN.
Many manufacturers offer such adapter
cards for almost all major brands of
computers. You can find lists of these
adapters on the Wi-Fi Alliance website:
http://www.weca.net .
Follow the manufacturer’s instructions for installing your wireless
adapter card, and using any scanning or networking utility they provide.
These vary by manufacturer.
Once your Netopia 3387W-ENT is installed and configured, and the
wireless LAN is enabled, your wireless client computers can join your
wireless LAN.
Various wireless security features are available, but disabled by default.
See Chapter 7, “Wireless LAN Configuration,” on page 7-1 for
instructions on enabling wireless security features.
