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.
9
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:
1
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.
2
Connect one end of the cable to the LAN Ethernet Port
on the rear of the Internet Server.
3
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.
1
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.
2
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.
3
Connect one end of the cable to the WAN Ethernet Port
on the rear of the Internet Server.
4
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.
10
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.
1
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.
2
Connect one end of the serial cable supplied with your
modem to Serial Port 1.
3
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.
11
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.
