In today’s fast-paced world, communication and sharing information are crucial.

Computer networks are among the fastest ways to share information, and 3Com

has brought this exciting technology into the home with the our home

networking product line.

The home networking products from 3Com give the home user the same power,

ﬂexibility, and protection that has been available only to large corporations. Now,

you can network the computers in your home, connect them all to a single

Internet outlet, and harness the combined power of all of your computers.

NSTALLATION

This chapter describes the panel layout of the Home Network Gateway, as well as

detailing the hardware installation procedure.

Panel Layout

Front Panel The front panel of the gateway contains 4 Ethernet ports.

Rear Panel The rear panel of the gateway contains three ports: the PRINT port, the WAN port,

and the COM port.

Ports 1 - 4 These ports function as your Ethernet switch. After you connect the devices to

these ports, (including computers, hubs, etc.), they can be networked together,

and you can share files between the computers on your home network.

1 2 3 4

PRINT Parallel port connector (25-pin D-type female). This is where you will connect the

shared printer.

WAN WAN port (RJ-45). This is where you will connect to your cable or DSL modem.

COM Serial port connector (9-pin D-type male). This is where you will connect your

analog or ISDN modem.

Installation

Requirements

The gateway can be positioned in any convenient place in your ofﬁce or home.

Follow these guidelines to ensure a troublefree installation:

■Place the gateway on a ﬂat horizontal surface.

■Keep the gateway away from any sources of heat.

■Do not place the gateway in a dusty or wet environment.

Be sure to turn off the power, remove the power cord from the outlet, and keep

your hands dry when connecting other devices to the gateway.

Ethernet Ports (1-4) The Ethernet port LEDs (green) will flicker when the corresponding port

is sending or receiving data.

WAN (globe icon) The WAN port LED (green) will flicker when the WAN port is sending or

receiving data.

Status (checkmark

icon)

The Status LED will flash once per second to indicate that the gateway

is functioning correctly.

Power connector (1) Plug the included power adapter into this connector. Use only the

power adapter that came with the gateway.

Power switch (2) Turns the power to the gateway on and off.

Hardware Installation 5

Hardware Installation This section details the cable connection procedures for the Home Ethernet

Gateway.

Computer Connection To create your home network, connect an Ethernet cable from the Ethernet port

of your computers to one of the Ethernet ports of the gateway, as shown in the

ﬁgure, below.

All networked computers must have Ethernet networking capabilities to connect

to the gateway.

Modem Connection There are two ways to connect modems to the gateway: using the WAN port (if

you are using a cable or DSL modem), or the COM port (if you are using an analog

or ISDN modem)

Cable or DSL Modem Connection

To connect a cable or DSL modem to the gateway, use one of the included

Ethernet cables to connect the WAN port of the gateway to your modem, as

shown in the ﬁgure below. See your cable or DSL modem documentation for

more details.

6CHAPTER 2: HARDWARE INSTALLATION

Analog or ISDN Modem Connection

To connect an analog or ISDN modem to the gateway, use a COM cable to

connect the COM port of the gateway to your modem, as shown in the ﬁgure

below. See your analog or ISDN modem documentation for more details.

Printer Connection To connect a printer to the gateway, connect the printer cable to the PRINT port of

the gateway, as shown in the ﬁgure, above.

To use your gateway as a print server, allowing you to share one printer across

your home network, see Chapter 5 of this user manual for more details.

Power To supply power to the gateway, insert the power adapter plug in the power

connector of the gateway (see “Left Side Panel” on page 4). Then, power up the

devices of your home network in the following order:

■Modem

■Home Ethernet Gateway

■Other devices (computers, printer, etc.)

Self-Test Phase

Once the gateway is powered up, it will automatically enter self-test phase. When

it is in self-test phase, the WAN and Status LEDs (see “Top Panel” on page 4) will

illuminate for about 5 seconds, and then ﬂash three times to indicate that the

self-test has ﬁnished. Finally, the Status LED will ﬂash once per second to indicate

that the gateway is operating normally.
