3 Mounting the Bridge
The bridge can be mounted on the following types of surfaces:
•Pole
•Wall
.
Using the Pole-Mounting Bracket
Perform the following steps to mount the unit to a 2 to 3 inch diameter steel pole or tube using the
mounting bracket:
1 Place the V-shaped part of the bracket around the pole and tighten the securing nuts just
enough to hold the bracket to the pole. (The bracket may need to be rotated around the
pole during the antenna alignment process.)
IP Address Record the bridge MAC address in a safe place before the bridge is installed in a
hard-to-reach location.
The MAC address is printed on the back of the bridge. Additional IP address labels
are shipped with the bridge.
Location The WL-575 bridge must only be installed outdoors. It is not for indoor use. The PoE
injector is for indoor use only. Plan your equipment location accordingly.
CAUTION: The bridge is intended for outdoor use only. Do not install the bridge indoors.

6
4 Attach the bridge with bracket to the plate already fixed to the pole.
5 Use the included nuts to secure the wireless bridge to the pole bracket. Note that the
wireless bridge tilt angle may need to be adjusted during the antenna alignment process.
Be sure to take account of the antenna polarization direction; all antennas in a link must be
mounted with the same polarization.
Using the Wall-Mounting Bracket
Perform the following steps to mount the unit to a wall using the wall-mounting bracket:
1 Always attach the bracket to a wall with the flat side flush against the wall (see following
figure).
CAUTION: The wall-mounting bracket does not allow the bridge’s integrated antenna
to be aligned. It is intended for deployment using a 5.0 GHz external antenna.
7
2 Position the bracket in the intended location and mark the position of the four mounting
screw holes.
3 Drill four holes in the wall that match the screws and wall plugs included in the bracket kit,
then secure the bracket to the wall.
4 Use the included nuts to tightly secure the wireless bridge to the bracket.
4 Connecting External Antennas
The bridge's primary antenna is it's built-in internal antenna. For some applications when deploying an
WL-575 unit for a bridge link or access point operation, you may need to mount external antennas and
connect them to the bridge. Typically, a bridge link requires a 5.0 GHz antenna, and access point
operation a 2.4
GHz antenna. WL-575 units acting as managed APs also require an external antenna for
2.4 GHz operation.
Perform these steps:
1 Mount the external antenna to the same supporting structure as the bridge, within 3 m
(10
ft) distance, using the bracket supplied in the antenna package.
2 Connect the antenna to the bridge’s N-type connector using the RF coaxial cable provided in
the antenna package.
3 Apply weatherproofing tape to the antenna connectors to help prevent water entering the
connectors.
8
5 Connecting Cables
1 Attach the Ethernet cable to the Ethernet port on the wireless bridge.
2 For extra protection against rain or moisture, apply weatherproofing tape (not included)
around the Ethernet connector.
3 Be sure to ground the unit with an appropriate grounding wire (not included) by attaching it
to the grounding screw on the unit.
NOTE: When you have connected external antennas, be sure to use the management
interface to configure the bridge for correct antenna operation.
CAUTION: Be sure that grounding is available and that it meets local and national
electrical codes. For additional lightning protection, use lightning rods, lightning arrestors,
or surge suppressors.

7 Checking the LED Indicators
The bridge’s 11a and 11b/g LEDs operate in two display modes, which are configurable through the
software. The default AP mode indicates data traffic rates. The RSSI mode indicates the received signal
power and is for use when aligning antennas in a bridge link.
When the bridge is connected to power, LEDs indicate as follows:
LED Color Indicates
Power Green The bridge is powered up and operating
normally.
Off The bridge is not receiving power or there is a
fault with the power supply.
Amber The system is under cold reset status.
Link Green The bridge has a 10/100 Mbps Fast Ethernet
connection, but there is no activity.
Flashing Indicates that the bridge is transmitting or
receiving data on a 10/100 Mbps Ethernet LAN.

8 Aligning Antennas
After wireless bridge units have been mounted, connected, and their radios are operating, bridge link
antennas must be accurately aligned to ensure optimum performance. This alignment process is
particularly important for long-range point-to-point links. In a point-to-multipoint configuration the root
bridge uses an omnidirectional or sector antenna, which does not require alignment, but bridge nodes
still need to be correctly aligned with the root bridge antenna.
• Point-to-Point Configurations – In a point-to-point configuration, the alignment process
requires two people, one at each end of the link. The use of cell phones or two-way radio
communication may help with coordination. To start, you can just point the antennas at each
other, using binoculars or a compass to set the general direction. For accurate alignment, you
must monitor the signal strength LEDs as the antenna moves horizontally and vertically.
• Point-to-Multipoint Configurations – In a point-to-multipoint configuration all bridge
nodes must be aligned with the root bridge antenna. The alignment process is the same as in
point-to-point links, but only the bridge node end of the link requires the alignment.
The signal strength LEDs indicate the received radio signal strength for a particular bridge link. The more
LEDs that turn on, the stronger the signal. Alternatively, you can monitor the Receive Signal Strength
Indicator (RSSI) value directly from the management interface. The higher the RSSI value, the stronger
the signal.
When you move the antenna during alignment, the radio signal from the remote antenna can be seen
to have a strong central main lobe and smaller side lobes. The object of the alignment process is to set
the antenna so that it is receiving the strongest signal from the central main lobe.
To align the antennas in the link, monitor the signal strength LEDs or the RSSI value in the management
interface. Start with one antenna fixed and then perform the following procedure on the other antenna:
Main Lobe

Horizontal Scan
Vertical Scan
RSSI
Value
Side Lobe

1 Pan the antenna horizontally back and forth while checking the LEDs. If using the pole-
mounting bracket with the unit, you must rotate the mounting bracket around the pole.
Other external antenna brackets may require a different horizontal adjustment.
2 Find the point where the signal is strongest (all LEDs on) and secure the horizontal
adjustment in that position.
3 Loosen the vertical adjustment on the mounting bracket and tilt the antenna slowly up and
down while checking the LEDs.
4 Find the point where the signal is strongest and secure the vertical adjustment in that
position.
Troubleshooting
Refer to the 3Com WL-575 Outdoor Building-to-Building Bridge and Access Point User's Guide or
the 3Com website (www.3Com.com) for troubleshooting information.
Note: The RSSI value can be configured through management interfaces to display a value
for specific WDS bridge links.
Note: Sometimes there may not be a central lobe peak because vertical alignment is too
far off; only two similar peaks for the side lobes are detected. In this case, fix the antenna
so that it is halfway between the two peaks.
