INTRODUCING THE ACCESS POINT
Welcome to the world of networking with 3Com®. In the modern
business environment, communication and sharing information is crucial.
Computer networks have proved to be one of the fastest modes of
communication but, until recently, only large businesses could afford the
networking advantage. The OfficeConnect® product range from 3Com
has changed all this, bringing networks to the small office.
The products that compose the OfficeConnect range give you, the small
office user, the same power, flexibility, and protection that has been
available only to large corporations. Now, you can harness the benefits of
wireless networking.

CHAPTER 1: INTRODUCING THE ACCESS POINT
Minimum System
and Component
Requirements
Front Panel
Your Access Point requires that the computer(s) and components in your
network be configured with at least the following:
■
A computer with an operating system that supports TCP/IP
networking protocols (for example Windows 95/98/NT/Me/2000/XP,
Unix, Mac OS 8.5 or higher).
■
An Ethernet 10Mbps or 10/100 Mbps or 10/100/1000 Mbps NIC.
■
An 802.11b wireless NIC.
■
A Web browser program that supports JavaScript, such as Netscape
4.0 or higher or Internet Explorer 5.0 or higher.
The front panel of the Access Point contains a series of indicator lights
(LEDs) that help describe the state of various networking and connection
operations.
Figure 2 Access Point - Front Panel
1 Alert LED
Orange
Indicates a number of different conditions, as described below.
Off - The Access Point is operating normally.
Flashing quickly - Indicates one of the following conditions:
■
The Access Point has just been started up and is running a self-test
routine, or
■
The administrator has invoked the Reset to Factory Defaults
command, or
■
The system software is in the process of being upgraded
In each of these cases, wait until the Access Point has completed the
current operation and the alert LED is Off.
Front Panel
15
Flashing slowly - The Access Point has completed the Reset to Factory
Defaults process, and is waiting for you to release the reset button. The
Access Point will then enter the start-up sequence and resume normal
operation.
If you have used the reset button to reset the unit to Factory Defaults,
follow steps 5 to 6 in “Forgotten Password and Reset to Factory
Defaults” on page 54.
Continuously on - A fault has been detected with your Access Point
during the start-up process. Refer to Chapter 5 “Troubleshooting”.
2 Power LED
Green
Indicates that the Access Point is powered on.
3 LAN Status LED
Green (100Mbps link) / yellow (10Mbps link)
If the LED is on, the link between the port and the next piece of network
equipment is OK. If the LED is flashing, the link is OK and data is being
transmitted or received. If the LED is off, nothing is connected, the
connected device is switched off, or there is a problem with the
connection (refer to Chapter 5 “Troubleshooting”). The port will
automatically adjust to the correct speed and duplex.
4 Wireless LAN (WLAN) Status LED
Yellow
If the LED is on it indicates that wireless networking is enabled. If the LED
is flashing, data is being transmitted or received. If the LED is off, the
Wireless LAN has been disabled in the Access Point, or there is a problem.
Refer to Chapter 5 “Troubleshooting”.
16
CHAPTER 1: INTRODUCING THE ACCESS POINT
Rear Panel
The rear panel (Figure 3) of the Access Point contains one LAN port, a
reset button, an MDI/X switch and a power adapter socket.
Figure 3 Access Point - Rear Panel
5 Wireless Antennae
The antennae on the product should be placed in a ‘V’ position when
initially installed.
CAUTION: Do not force the antennae round further than 90 degrees in
either direction.
6 Power Adapter Socket
Only use the power adapter supplied with this Access Point. Do not use
any other adapter.
7 Ethernet Port
Use the supplied patch cable to connect the Access Point to the LAN. The
port will automatically adjust to the correct speed and duplex.
8 Reset Button
This button allows you to reset the unit to factory defaults.
9 Uplink/Normal Switch
This switch affects the operation of the Ethernet Port. If you are
connecting the Access Point to a Hub or a Switch, set the switch to
Uplink (in). If you are connecting to a PC, set the switch to Normal (out).

Introduction
HARDWARE INSTALLATION
This chapter will guide you through a basic installation of the Access
Point, including:
■
Connecting the Access Point to your network.
■
Setting up your computers for networking with the Access Point.
Safety Information
WARNING: Please read the “Safety Information” section in Appendix D
before you start.
VORSICHT: Bitte lesen Sie den Abschnitt “Wichtige Sicherheitshinweise”
sorgfältig durch, bevor Sie das Gerät einschalten.
AVERTISSEMENT: Veuillez lire attentivement la section “Consignes
importantes de sécurité” avant de mettre en route.
Positioning the
Access Point
You should place the Access Point in a location that:
■
allows convenient connection to the computer or other ethernet
device that will be connected to the LAN port on the rear panel.
■
allows easy viewing of the front panel LED indicator lights, and access
to the rear panel connectors, if necessary.
■
is centrally located to the wireless computers that will connect to the
Access Point. A suitable location might be on top of a high shelf or
similar furniture to optimize wireless connections to computers in
both horizontal and vertical directions, allowing wider coverage.
18
CHAPTER 2: HARDWARE INSTALLATION
When positioning your Access Point, ensure:
Using the Rubber
Feet
Wall Mounting
■
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.
■
Air flow around the unit and through the vents in the side of the case
is not restricted. 3Com recommends you provide a minimum of
25 mm (1 in.) clearance.
Use the four self-adhesive rubber feet to prevent your Access Point from
moving around on your desk or when stacking with other flat top
OfficeConnect units. Only stick the feet to the marked areas at each
corner of the underside of your Access Point.
There are two slots on the underside of the Access Point that can be used
for wall mounting.
When wall mounting the unit, ensure that it is within reach of the power
outlet.
You will need two suitable screws to wall mount the unit. To do this:
1 Ensure that the wall you use is smooth, flat, dry and sturdy and make two
screw holes which are 150 mm (5.9 in.) apart.
2 Fix the screws into the wall, leaving their heads 3 mm (0.12 in.) clear of
the wall surface.
3 Remove any connections to the unit and locate it over the screw heads.
When in line, gently push the unit on to the wall and move it downwards
to secure.
When making connections, be careful not to push the unit up and off the
wall.
CAUTION: Only wall mount single units, do not wall mount stacked
units.
Powering Up the Access Point
Powering Up the
Access Point
19
To power up the Access Point:
1 Plug the power adapter into the power adapter socket located on the
back panel of the Access Point.
2 Plug the power adapter into a standard electrical wall socket.
Connecting the
Access Point
The first step for installing your Access Point is to physically connect it to a
switch or hub. See Figure 4.
Figure 4 Connecting the Access Point
To use your Access Point to connect to the wireless LAN to the wired LAN:
1 Insert one end of the supplied Ethernet (RJ-45 Category 5) cable into the
LAN port on the rear panel of the Access Point.
2 Insert the other end of the cable into the RJ-45 port on switch or hub.
Check that the LAN status LED lights on the Access Point.
You have now completed the hardware installation of your Access Point.
Next you need to set up your computers so that they connect to the
Access Point.
