Installation Guide
802.11g mini-PCI Radio Module
MODEL WL-463
The 3Com 802.11g mini-PCI Radio Module kit contains everything you need to install an additional radio and
antenna into your 3Com Access Point.
Kit Contents
The upgrade kit contains these items:
• one antenna module
• one 802.11g mini-PCI Radio Module
• two cables
• two antennas
1 Detach and disconnect the access point.
If the access point is mounted on the wall, turn the unit counterclockwise to disengage it from the mounting
plate. Disconnect the Ethernet cable. Place the access point face down on a static-free surface.
2 Remove the back cover.
Using a cross-tip screwdriver, remove the four screws from the back cover. Remove the cover from the unit. Set
the cover and screws aside.
3 Remove the antenna housing.
Grasp the inside edge of the antenna housing and pull up to disengage the housing from the
unit, as shown below. This part is no longer needed.
4 Install the radio board.
Holding the radio board at an angle, align the contact edge with the mini PCI connector on the unit. Make sure
the keying notch on the contact edge lines up with the key on the connector, as shown in the detail below. Slide
the board into the connector and press down gently until the two retainer clips snap into place.
5 Attach the cables to the antenna module.
With the notched side of the square connector facing up (button side facing down), insert one cable connector
into the B1 connection on the antenna module and push gently until it snaps into place. Attach the other cable
connector to the B2 connection in the same manner.
6 Attach the antenna module and connect the cables.
1 Align the antenna module with the snaps and posts on the unit and press until the module
snaps firmly into place. Make sure the cables are routed through the slots in the unit.
2 Align the free end of one cable with one connector on the board. Press until the cable snaps
into place. Repeat with the other cable and the other connector. (You can connect either cable
to either connector; the order is not important.)
3 After the cables are connected, press them down out of the way inside the housing.
7 Replace the back cover.
Make sure that the cables are tucked away inside the housing so that they do not obstruct the cover. Align the
back cover with the unit and settle the cover into place. Tighten the four screws.
8 Attach the antennas.
Being careful not to touch the antenna tips, screw the antennas onto the SMA connectors and hand tighten
them. After network startup, you may need to adjust the antennas to fine tune radio coverage.
9 Reinstall the access point.
Reconnect the Ethernet cable and reattach the access point to the wall mounting plate. Adjust the antennas to
improve the radio signal, if necessary.
SELECTING AND CONNECTING A DIFFERENT
ANTENNA MODEL
The standard detachable antennas supplied with the WL-463 11g mimi-PCI radio module and are suitable
for a broad variety of environments. If you require a different type of antenna several options are available
by model number from the 3Com Web site (www.3Com.com).
For each of the antenna models, you will need either a 6-foot accessory cable (model 3CWE480), a 20-foot
accessory cable (model 3CWE481) or a 50-foot accessory cable (model 3CWE482) to provide the transi-
tion from the SMA connector on the access point to the N-type connector on the antenna. To ensure the
physical safety of anyone near the antenna and to prevent damage to the access point, follow the building
codes for antenna installations in your area. Also, when connecting the optional antenna to the access point,
remember to use only the A-side connector on the access point, on the right when properly installed.
1 Position the antenna so that there are minimal obstacles between it and any client with which it will
communicate. While maintaining a direct line of sight between the antenna and a client is not strictly necessary,
such an arrangement helps to ensure a strong signal. Ensure that access is available for routing the antenna
cablefrom the antenna to the access point.
2 If they are installed, remove both arms of the standard detachable antenna, making sure not to handle the tips
of the antenna.
3 Connect one end of the optional antenna cable to the antenna and secure the antenna in place.
4 Connect the free end of the antenna cable to the right-hand side connection on the access point, as shown in
the illustration above.
5 Make certain that the antennas and antenna masts are appropriately grounded to prevent injury or damage
from lightning strikes.
