HARDWARE INSTALLATION

Introduction 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

Positioning the Access Point

WARNING: Please read the “Safety Information” 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.

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 simil ar

furniture to optimize wireless connections to computers in both horizontal

and vertical directions, allowing wider coverage.

section in Appendix D

18 CHAPTER 2: HARDWARE INSTALLATION

When positioning your Access Point, ensure:

■ 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.

Using the Rubber Feet 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.

Wall Mounting There are two slots on the underside of the Access Point that can be used for

wall mounting.

Powering Up the Access Point

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.

CAUTION: Only wall mount single units, do not wall mount stacked units.

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 19

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

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) ca ble 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.

20 CHAPTER 2: HARDWARE INSTALLATION

RUNNING THE SETUP WIZARD

Accessing the Wizard 3Com recommends that you perform the initial Access Point configuration

from a computer that is directly connected to the LAN port and not from a wireless connection.

However, you may configure the Access Point from a wireless admin computer but, note that you may lose contact with the Access Point if you change the wireless configuration. To communicate with the Access Point, your wireless NIC should be set as follows:

■ Encryption — none

■ Service Area Name/SSID — 3Com

The Access Point setup program is Web-based, which means that it is accessed through your W eb browser (Netscape Navigator , Internet Explorer or Mozilla).

To use the Setup Wizard:

1 Ensure that you have at least one computer connected to the Access Point.

Refer to Chapter 2

2 Insert the Access Point CD-ROM in the CD-ROM drive on your computer . A

menu will appear; select Discovery.

Discovery will find the Access Point even if it is unconfigured or misconfigured.

for details on how to do this.

22 CHAPTER 3: RUNNING THE SETUP WIZARD

Figure 5 Discovery Welcome Screen

3 When the Welcome screen is displayed, select the NIC from which the Access

Point will be discovered. Then click on Next and wait until the application discovers the Access Points connected to your LAN.

Figure 6 Discovered Access Point Screen

4 Figure 6 shows an example Discovered Devices screen. Highlight the Wireless

11a/b/g Access Point by clicking on it, and press Next.

If the discovery application finds multiple Access Points compare the serial number on the Discovered Devices Screen with the serial number on the base of your Access Point.

The Country Selection screen is only displayed on initial config ura tion of the Access Point.

Figure 9 Country Selection Screen

9 When you have logged in and selected a country either:

■ The Status screen will appear (Figure 10). Select the Wizard option from

the menu on the left hand side. or

■ If your Access Point has not been configured before, the Wizard page will

be shown (refer to Figure 10

10 Click Next. 11 You will be guided step by step through a basic setup procedure.

Figure 10 Welcome Screen

Accessing the Wizard 25

Figure 11 Setup Wizard

26 CHAPTER 3: RUNNING THE SETUP WIZARD

1 Select channels for the Access Point to use or Auto if you want the Access

Point to choose an unused channel on start-up.

2 Enter a Service Area Name/SSID.

The Service Area Name default for 3Com products is “3Com”. Up to 32 (case sensitive) characters can be entered for the Service Area Name .

3Com strongly recommends that you c hange the SSID to someth ing other than the default.

For information on improving your Wireless network security see “Wireless

Settings” on page 39.

If you are configuring the Access Point from a wireless computer any changes you make to the wireless configuration will result in communication between the Access Point and your computer being lost. This is why 3Com strongly recommends that you configure the Access Point from a wired computer.

It is very important that you set up your wireless clients to use the same Service Area Name or SSID as the one you use on this screen. If your clients use a different Service Area Name then they will not be able to communicate with the Access Point.

The choice of channel is less important as Clients will generally search all of the available channels. You should however make a note of the channel you select as this may be useful if you experience problems with your clients.
