1. Introduction

Congratulations on your purchase of the Harmony 8430 Series

802.11b PC Card wireless LAN adapter. The Harmony 8430

Series 802.11b PC Card is a long range, high performance,

wireless LAN adapter card that complies with the IEEE 802.11b

standard.

The Harmony 802.11b PC Card supports Windows 95, Windows

98, Windows 2000, and Windows NT. Computers with the

Harmony 802.11b PC Card installed “look” like standard

network nodes to the operating system.

The Harmony 802.11b PC Card can be used with other 802.11b

PC Cards to form a stand-alone wirefree Ad Hoc network or

used in conjunction with a Harmony infrastructure to provide

mobile clients with wirefree access to an Ethernet network.

Proxim is the leading supplier of wirefree networking solutions.

Proxim’s unmatched expertise in spread spectrum radio network-

ing technology, combined with the company’s extensive experi-

ence serving the communication needs of the mobile computing

user, have kept Proxim at the forefront of the wireless LAN

market.

The Harmony Family

The Harmony 802.11b PC Card is a member of a product family

that provides a complete wirefree networking solution.

qThe Harmony Access Point Controller Model 7560

centralizes the management, security, and filtering

capabilities of a wireless LAN. The Access Point

Controller communicates with Harmony Access Points

over the Ethernet network to provide wirefree network

access for mobile clients. The Access Point Controller

can support multiple Access Points, even if each Access

Point follows a different wireless standard.

qThe Harmony Access Point is a networking bridge that

operates at Layer 2 of the OSI networking model.

Working in conjunction with a Harmony Access Point

Controller, the Access Point forwards packets between

its radio and the Ethernet network. Two models of the

Harmony Access Point are available to support either

the OpenAir or IEEE 802.11b wireless standards: the

OpenAir Access Point Model 7550 and the 802.11b

Access Point Model 8550. Note that the Harmony

Power System operates only with the 802.11b Access

Point.

qThe optional Harmony Power System Model 7562

provides remote DC power to Harmony 802.11b Access

Points over the unused pins of a twisted pair Ethernet

cable.

qThe Harmony PC Card is a wireless LAN adapter that

fits into a PCMCIA Type II slot in a laptop computer.

Two models of the Harmony PC Cards are available to

support either the OpenAir or IEEE 802.11b wireless

standards.

The Harmony 802.11b PC Card Model 8432, which includes an

integrated antenna (with built-in diversity), is shown in Figure 1.

Figure 1

Harmony 802.11b PC Card With Integrated Antenna

(Model 8432)

Warning!

Do not attempt to remove the antenna from the Model

8432 PC Card. This will damage the card and

antenna.

qA Harmony Installation CD containing drivers and

qOne Harmony 8430 Series 802.11b PC Card User’s

Guide

If any of these items are missing or damaged, please contact

your reseller or Proxim Technical Support.

must have the following minimum requirements:

qA computer with a PCMCIA Type II slot.

qWindows 95, Windows 98, Windows 2000, or

Windows NT

qAt least one other IEEE 802.11b-compatible product

installed on the network (this includes other Harmony

802.11b products)

2. Installation

This chapter describes how to install the Harmony 802.11b PC

Card and software in a computer running Windows 95, 98, 2000,

and NT.

Windows 95/98 Installation

This section describes how to install the Harmony 802.11b PC

Card in a computer running either Windows 95 or Windows 98.

Pre-installation Considerations

Before beginning the installation of a Harmony 802.11b PC

Card, confirm that you have a Windows CD or diskettes avail-

able (either Windows 95 or Windows 98, depending on the

computer’s operating system). You may be prompted to insert a

Windows CD during the installation.

If you do not have the Windows CD or diskettes, it is possible

that you already have the Windows 95 or Windows 98 installa-

tion files on your hard disk. These Windows installation files

are known as Windows Cabinet files or CAB files. The Win-

dows Cabinet files are commonly located in

C:\WINDOWS\OPTIONS\CABS.

Note:

You may need the Windows CD, diskettes, or Cabinet

files to complete the installation of the Harmony

802.11b PC Card. Proxim recommends that you do

not proceed with the installation until you have con-

firmed that you have one of these Windows 95 or

Windows 98 installation media available.

Note to Customers Who Have a Laptop Without a

CD-ROM Drive

If you are installing a Harmony 802.11b PC Card in a laptop that

does not have a CD-ROM drive, you should follow the steps

below prior to installing the Harmony software:

1. Confirm that the Windows cabinet (CAB) files are

installed on the computer. The CAB files are typically

located in C:\WINDOWS\OPTIONS\CABS\.

2. If the computer does not have the CAB files installed, copy

the WIN95 or WIN98 folder, found on the Windows

CD-ROM, to a temporary folder on the computer.

3. Copy the contents of the Harmony Installation CD-ROM to

a temporary folder on the computer. Alternatively, you

may download the Harmony software from Proxim’s Web

site at http://www.proxim.com/support/.

4. Follow the installation instructions contained in this chap-

ter. When the instructions call for either the Windows CD

or the Harmony Installation CD, direct the installation

wizard to search the temporary folders you created in Steps

#2 and 3 above.

5. When the installation is complete, remove the temporary

folders you created in Steps #2 and #3 above from the

computer’s hard drive.
