ARDWARE

This chapter describes the panel layout of the Home Network Gateway, as well as detailing the hardware installation procedure.

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

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.

NSTALLATION

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

and the COM port.

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

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

shared printer.

■ 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.

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.

6 CHAPTER 2: HARDWARE INSTALLATION

COM

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

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.

NETWORK SETTINGS

This chapter explains how to conﬁgure the network settings of the computers on your home network running Windows 95, 98, and NT 4.0, and Macintosh operating systems.

Network Settings The default IP address of this product is 192.168.2.1, and the default subnet mask

IP address is 255.255.255.0. These addresses can be changed, but these default values are used throughout this manual.
