Check that your package includes the following items:
•One Internet Gateway
•One CD-ROM
•One power adapter and power cord
•One Ethernet cable
•Installation instructions, including a Quick Start for cable
modem users, and this User Guide.
If anything is missing or damaged, please contact your supplier.
1.2 You Will Also Need
The IG-4160 is compatible with computers using the Windows,
Macintosh, and Linux operating systems.
Optionally, you can use your Gateway as a print server and share a
parallel port printer connection among multiple PCs. (Note: This
option is only for Windows computers.) If you want to use your
Gateway as a print server, you will need a standard parallel printer
and cable.

The first step is to decide what type of WAN device you intend to
use to access the Internet. (Your choices are depicted on the left-
hand side of the diagram above.)
Once you’ve made that decision, the key stages to set up and use
your Gateway are as follows:
1

1Connect the hardware.
2

2Establish wired communication with the Gateway using a PC
that we’ll call the Administrator PC.

Using the following flowchart as a road map should simplify the
process of setting up your Gateway. You can also keep this
flowchart as a handy reference, should you ever want to modify
your Gateway setup.

6 IG-4160 Zoom Internet Gateway User Guide
In this manual we also describe additional options and features
available to you. For example, you can connect a printer to your
Gateway and share it among multiple users. You can also add more
sophisticated capabilities to the Gateway. For instance, you can
modify its built-in firewall protection to accommodate special
gaming or video applications. The flowchart also includes these
additional chapters.

connections will originate from this back panel.
Port Description
COM Serial port in case you want to connect a dial-up or ISDN
modem
PRINTER Parallel printer port for optional printer
1A LAN port for connecting networked computers and other
10/100BaseT Ethernet LAN devices

and other 10/100BaseT Ethernet LAN devices
WAN In case you want to connect an Ethernet cable or DSL
modem
12VDC Power: DC 12V, 1.5A (minimum)
Before connecting your modem and Gateway, be sure to review
the following pre-installation checklist.
PRE-INSTALLATION CHECKLIST
Review this checklist before setting up your Gateway and modem
✔Check with your service provider: If you have a cable modem,
you may have to register your Gateway’s WAN MAC address
before setting up the Gateway. Note: The WAN MAC address
is printed on the Gateway’s bottom case label.
✔Is your Internet or online service working properly? If
necessary, refer to the instructions provided by your service
provider.
✔Check that an Ethernet NIC card is already installed in your
PC, then turn to page 9.

the 12VDC power jack on the back of the Gateway and
then plug the other end into a wall outlet. The Gateway’s
SYS indicator will come ON for about 10 seconds, and
then it will flash rapidly a few times. When the indicator
flashes continuously once per second, the start-up process
is complete, and your Gateway is ready.
