NSTALLING

THE

NTERNET

ERVER

Where the Internet Server fits in the Network

The Internet Server must always be placed between the

device that is used to connect to the Internet (called the

Internet Gateway in this guide) and the rest of your

network. You connect to your network through a hub or

switch.

Positioning the Unit

When installing your Internet Server, ensure:

■

It is installed horizontally.

■

It is out of direct sunlight and away from sources of heat.

■

Cabling is away from power lines, fluorescent lighting

fixtures, and sources of electrical noise such as radios,

transmitters and broadband amplifiers.

■

Water or moisture cannot enter the case of the unit.

■

Ensure that the airvents are not obstructed and that air

flow around the unit and to the fan in the rear of the

case is not restricted. 3Com recommends you provide a

minimum of 25 mm (1 in.) clearance.

For security reasons, 3Com recommends that you install the

Internet Server in a locked room or cupboard where it

cannot be tampered with. 3Com also recommends that, if

possible, you connect the Internet Server to an

Uninterruptable Power Supply to maintain services in the

event of a mains power failure.

Installation Flowchart

This flowchart provides a brief overview of the installation

process. Full instructions are provided in the sections that

follow.

Install your Network and Network Software

The Internet Server provides a connection to a 10BASE-T or

100BASE-TX network. It connects like any other computer

to a hub or a switch on your network.

Before installing the Internet Server, install your hub or

switch and cables. You should also install Network Interface

Cards (NICs) in all the PCs on your network that do not

already have an Ethernet connection built in.

Each PC must also have TCP/IP drivers installed so that it can

communicate with the Internet Server. For more information

about installing TCP/IP drivers, refer to your PC User Guide,

your NIC User Guide or your Windows manual. The TCP/IP

configuration can be carried out by the Internet Server

Client Wizard.

Install your Internet Gateway Device

The Internet Server is designed to work with any Internet

Gateway device that provides either:

■

an Ethernet 10BASE-T or 100BASE-TX connection (such

as LAN modem or router)

■

a serial RS-232 connection (dial up modem device).

The connection you use to access your Internet Service

Provider (ISP), depends on the type of Internet Gateway

device you choose and the services offered by your ISP.

Connect the Internet Server to the local network and to the

Internet Gateway, and power it on. See “Connecting to your

Network” on page 9. Wait for approximately three minutes. The

Internet Server will beep twice to show it has initialized.

Run the Internet Server Client

Wizard CD on the System

Administrator PC. See “Running

the Client Wizard” on page 12.

Open a browser on the

System Administrator PC

and browse to the

Internet Server’s Web

interface at http://is:8000.

Complete the Internet Server

Installation Wizard. See

“Running the Internet Server

Installation Wizard” on page 16.

Create user accounts on

the Internet Server through

the Web interface.

If needed, use the Internet Server

Client Wizard CD to install a

browser, e-mail client and help

files on the other PCs on the

network.

Reboot the PCs to obtain

an IP address from the

Internet Server, if the

Internet Server is the

DHCP Server.

Before installing the Internet Server, install your Internet

Gateway and check that you can connect to your ISP. If you

intend to use e-mail, check that you can send and receive

e-mail across the Internet into your ISP mailbox.

If you have any problems connecting to the Internet, do not

install the Internet Server until these have been resolved.

Check the User Guides supplied with your Internet Gateway

device and, if necessary, consult with your ISP’s technical

support service. If the fault lies in the physical connection to

your ISP, you may need to contact your telecom’s service

provider for assistance.

Connecting to your Network

The Internet Server is connected to your network like any

other computer. The LAN Ethernet Port automatically sets

itself to the speed of your network (10 Mbps or 100 Mbps).

To connect the Internet Server:

Where possible use the Ethernet cable supplied with the

Internet Server. If this is not long enough, use a length

of straight through CAT5 twisted pair cable with RJ-45

connectors at each end.

Connect one end of the cable to the LAN Ethernet Port

on the rear of the Internet Server.

Connect the other end of the cable to the hub or switch

on your network. If you are using a long length of cable,

you may want to label this end of the cable so you can

easily identify it in future.

Connecting to your Internet Gateway

The Internet Gateway device is totally independent of the

Internet Server allowing you to choose the connection to

the Internet which best suits your business. The Internet

Gateway device can connect to your ISP through a

permanent or dial up connection.

You can connect to your Internet Gateway in one of two

ways:

Ethernet WAN Connection

If your Internet Gateway device has an Ethernet port, you

can connect the Internet Server directly to the gateway.

If you have not already done so, install your Internet

Gateway following the instructions in the User Guide

supplied with it. Check that you can connect to your ISP.

Use one of the Ethernet cables supplied in the box. If this

is not long enough, use a length of straight through

CAT5 twisted pair cable with RJ-45 connectors at each

end.

Connect one end of the cable to the WAN Ethernet Port

on the rear of the Internet Server.

Connect the other end of the cable to Ethernet port on

your Internet Gateway device. If you are using a long

length of cable, you may want to label this end of the

cable so you can easily identify it in future.

Serial Port 1

If you are using a dial up connection through a modem or a

Euro ISDN Terminal Adapter, use Serial Port 1 to connect the

Internet Server to your ISP.

If you have not already done so, install your modem fol-

lowing the instructions in the User Guide supplied with

it. Check that you can connect to your ISP.

Connect one end of the serial cable supplied with your

modem to Serial Port 1.

Connect the other end of the serial cable to the serial

port on your modem.

Connecting a Printer

The parallel printer port on the rear panel can be used to

connect any printer to the Internet Server using a standard

parallel printer cable. The Print Server can then be

configured to allow network users access to this printer.

■

For more information about configuring the Print Server,

see the Internet Server User Guide.

■

For information about installing and setting up your

printer, see your printer’s User Guide.

Powering on the Internet Server

Setting the Mains Voltage

CAUTION: Before powering on the Internet Server for

the first time, ensure that the voltage selector is set to

operate correctly with your mains supply.

The Internet Server is shipped with the voltage set to 230V

AC by default. This is suitable for mains supply of 200 to

240V AC.

If your mains power supply provides 90 to 120V AC, you

must set the switch to 115V AC on the Internet Server.

Powering On

When you have made all the connections, power on the

Internet Server. When the Internet Server starts, it beeps

once. When it has initialized and is ready for use, you will

hear 2 short beeps; this takes about three minutes.

The Internet Server starts up with its default settings but

cannot be used until you have run the Client Wizard on the

System Administrator PC and the Internet Server Installation

Wizard.

Check that the link LEDs on both end of the LAN connec-

tion are lit (see the Internet Server back panel for the LAN

Link LED) and then continue the installation by running the

Client Wizard on the System Administrator PC.

Power Down Procedure

Before powering down the Internet Server you should

ensure that all users have disconnected from the Internet

Server.

There are two recommended ways you can power down the

Internet Server:

■

Using the On/Off Switch — Press the on/off switch

and release it immediately. You will hear 2 short beeps to

indicate that graceful shutdown has started. After a short

while the Internet Server powers off.

■

Through the Web interface — See the User Guide for

instructions on shutting down the Internet Server using

the web interface.

CAUTION: Never close down the Internet Server by

simply removing the power cable as you risk losing

data if you do this.

To prevent loss of data in the event of mains power

loss, 3Com recommends that where possible that the

Internet Server is connected to an uninterruptable

power supply.

In the event of a major problem, you may be

instructed by your Technical Support Representative to

carry out an Ungraceful Shutdown. To do this, press

the on/off switch for 5 seconds and you will hear 2

short beeps to indicate that ungraceful shutdown has

started. The Internet Server powers off immediately.
