Check the Package Contents

Before you start with the installation, verify that your PCI Adapter

package includes the following items:

■ One 3Com Wireless 11n PCI Adapter with standard PCI

bracket

■ Three remote antennas

■ One low-profile PCI bracket

■ One 3Com Installation CD-ROM, which contains the driver

for the PCI Adapter

■ This 3Com Wireless 11n PCI Adapter Quick Installation Guide

■ One warranty flyer

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

3Com network supplier immediately.

Check the Minimum System Requirements

You can install the PCI Adapter on any desktop computer with

Microsoft

®

Windows

®

XP, Windows 2000, or Windows Vista.

If using Windows 2000, please download the driver and utility

from the 3Com web site.

Your computer must also have, at least, the following:

■ Available PCI slot

■ 733 MHz Intel

™

Pentium

™

III or Celeron processor (or

equivalent)

■ 256 MB of RAM

4 Check the Package Contents

■ 7 MB of free disk space

■ CD-ROM drive

Check the PCI Bracket

The standard PCI bracket to which the PCI Adapter is attached by

default is for standard, full-height desktops. If you are using a

low-profile desktop, you need to replace the standard bracket

with the low-profile bracket for the PCI Adapter to fit.

To replace the PCI bracket:

1 Remove the three nuts and washers attached to the three

threaded antenna connectors.

2 Remove the two screws that secure the PCI Adapter to the

bracket. (Be careful not to let the shielding cover fall off, as these

screws also hold that in place.) Save the screws.

3 Replace the standard bracket with the low-profile bracket.

4 Fasten the PCI Adapter to the low-profile bracket with the screws.

5 Replace the three nuts and washers that you removed in step 1.

To install the PCI Adapter into a PCI slot:

1 Shut down your computer, and unplug the power cord from the
