OfficeConnect 54 Mbps 11g Access Point Features
Observing Safety Precautions
This equipment must be installed in compliance with local and national building codes, regulatory
restrictions, and FCC rules. For the safety of people and equipment, only professional network
personnel should install the Access Point.
Feature Description
Power Port The power port connects to the external power supply. Use only the 3Com
external power supply included in this package to power the Access Point.
Ethernet Port The Ethernet port provides a 10/100BASE-TX Ethernet connection to a
3Com Wireless LAN switch. Use a suitable RJ45 cable to connect your
Access Point to a computer or other equipment that has an Ethernet port
(such as a hub or a switch). This port has an automatic MDI/MDIX feature,
which allows you to use either a straight-through or a crossover cable.
LEDs The LEDs indicate power and network activity. See “Checking the LED
Indicators” on page 5 for details.
Antenna Connector One RSMA antenna connector allows you to connect an antenna that
operates in the 2.4 GHz band.
Reset Button Push the reset button to restart the Access Point. To return the unit to
factory defaults, power off the unit, press and hold the Reset button, and
power on the unit again. Continue holding the Reset button for 15 seconds
and release. Cycle power again and AP will have the factory defaults.
WARNING: To comply with FCC radio frequency (RF) exposure limits, a minimum
body-to-antenna distance of 20 cm (8 in.) must be maintained when the Access Point is
operational.
WARNING: To avoid possible injury or damage to equipment, you must use power supply
equipment that is safety certified according to UL, CSA, IEC, or other applicable national or
international safety requirements for the country of use. All references to power supply in this
document refer to equipment meeting these requirements.

1. Unpacking the Access Point
Make sure that you have the following items, which are included with the Access Point:
•One OfficeConnect Wireless 54 Mbps 11g Access Point
•One 3Com power adapter for use with the Access Point
•One cradle for vertical tabletop mounting
•Wall-mounting hardware: includes two threaded screws
•One CD-ROM containing the Setup Wizard software and
an additional copy of this Quick Start Guide
•One Warranty Flyer
2. Preparing for Installation
It is advisable to connect the power and check the Ethernet cables and LEDs before installing the
Access Point in a hard-to-reach location. Additionally, observe the following items before
mounting or connecting the Access Point:
3. Attaching the Antenna
Carefully unpack the standard detachable antenna that came included with your Access Point.
Screw the antenna on to the antenna connector on the Access Point and hand-tighten it. After
network startup, you may need to adjust the antenna to fine-tune coverage in your area.
For best results, adjust the antenna so that it is perpendicular to the floor and ceiling.
Installation Item Description
Hub or Switch To connect your wireless network to your wired network you will need an
additional hub or switch connected to the Access Point’s Ethernet port.
Cabling Make sure that standard Ethernet cable is installed at the site before you
install the Access Point.
Power
Requirements
Power can only be supplied using 3Com Power Adaptor which is included
with the Access Point.
Make sure the power outlet is accessible. The power supply plug is the only
means of disconnecting the Access Point from power.
MAC Address Record the Access Point MAC address in a safe place before the
Access Point is installed in a hard-to-reach location.
The MAC address is printed on the back of the Access Point.
CAUTION: Do not handle the antenna tips, especially after they are connected to the
Access Point. This could lead to electrostatic discharge (ESD), which could damage the
equipment.

4. Mounting the Access Point
.
Wall Mounting
To mount the Access Point to a wall:
1Locate a position on the wall which is free of obstructions.
2Screw two mounting screws into the wall 85 mm apart.
3Connect the Ethernet cable and power cable to the ports on the side of the Access Point.
4Align the holes on the back of the Access Point with the screws and hang the Access Point
on the screws.
Tabletop Mounting
To install the Access Point on a flat surface such as a table or desktop:

5. Checking the LED Indicators
When the Access Point is connected to power, LEDs indicate activity as described in the following
table. A steady lit LED indicates connection; a blinking LED indicates activity.
6. Configuring the Access Point
The CD shipped with your Access Point includes software to help you set up and administer the
Access Point. Perform the following steps to configure your Access Point for the first time:
1Insert the 3Com Access Point CD into your PC's CD-ROM drive. Your PC must be on your
wired network to set up the Access Point.
2When the OfficeConnect Installation screen appears, click Run Discovery Application.
If the Installation screen does not appear automatically, launch the program by typing
d:\setup.exe (where “d” is the drive letter for your PC’s CD-ROM drive).
3Follow the Setup Wizard’s instructions on the screen.
4(Optional) Change the default settings.
The Access Point is preconfigured with common default parameters. If you want to change
these settings, use your Web browser to configure the Access Point using its Web-based
interface.
The default wireless settings for the Access Point are:
LED Color Indicates
Power Green The Access Point is powered up and
operating normally.
Off The Access Point is not receiving power
or there is a fault with the power supply.
WLAN Green If the LED is on it indicates that wireless
networking is enabled. If the LED is
flashing, the link is OK and data is being
transmitted or received.
Off No wireless link is present.
LAN Green If the LED is on, the Ethernet 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.
Off No Ethernet link is present.

7. Troubleshooting
What to do if the Setup Wizard does not detect your
Access Point
Be sure the Access Point has finished booting
If you run the Setup Wizard before the Access Point has fully booted, the application may not be
able to find the device. During its boot-up sequence, the Access Point tries to get an IP address
from a DHCP server on the network. After 2 to 3 minutes of trying unsuccessfully, the Access Point
sets itself to use the factory default static IP address of 192.168.1.250, subnet mask
255.255.255.0. Sometimes the default IP address will appear in the Setup Wizard just before the
proper DHCP-assigned address is set. If opening the web browser to manage the Access Point is
initially unsuccessful, try running the wizard again to get the proper address.
Be sure the Access Point and your PC are on the same network
The Access Point and the PC must be on the same wired network and subnetwork for the Setup
Wizard to be able to detect the Access Point.
Connect to the Access Point manually
During boot up, if the Access Point does not detect a DHCP server after 2 or 3 three minutes, it
will assign itself the factory default static IP address of 192.168.1.250, subnet mask
255.255.255.0. To communicate with the Access Point using the default address, follow this
procedure:
1Set the IP address of your PC to any address in the same IP subnet as the Access Point (for
example 192.168.1.10), with subnet mask the same as the Access Point (255.255.255.0).
2Point your web browser at the Access Point default address: 192.168.1.250.
3At this time you will be able to log in and change the operating mode, and change the static
IP address if needed.
3Com recommends that you set a static IP address in the Access Point so that you will always
know the IP address. Depending on the DHCP server used, a different IP address could be assigned
to the Access Point with each reboot.
Reset the Access Point to Factory Defaults
To return the Access Point to the factory defaults power off the unit, press and hold the Reset
button, and power on the unit again. Continue holding the Reset button for 15 seconds and
release. Cycle power again and the Access Point will have the factory default conditions.
Note that the default IP address will only become available after the Access Point spends 2 to 3
minutes searching for an address from a DHCP server.
