Bridge and Access Point
3CRWEASYA73 / WL-575
The 3Com WL-575 802.11a Outdoor Building-to-Building Bridge and Access Point provides IEEE
802.11a or 802.11b/g wireless access to the network. The bridge offers a fast, reliable, and costeffective solution for connectivity between remote Ethernet wired LANs or to provide Internet access
to an isolated site.
Power is supplied by Power Over Ethernet (PoE) using a:
• 3Com propriety PoE Injector (output: 48V 60W)

The Ethernet port provides a 10/100BASE-TX Ethernet connection to a 3Com Wireless
LAN switch. The connection can be direct to a 3Com switch or indirect through an
intermediate Layer 2 or Layer 3 network.
Use a standard Category 5e cable or better with straight-through signaling and
standard RJ-45 connectors to connect the bridge to the switch on the network.
The bridge should be powered via proprietary Power Over Ethernet (PoE) power

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 bridge.
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 bridge 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 Bridge
Make sure that you have the following items, which are included in the package:
• One 3Com Outdoor 11a Building to Building Bridge and 11bg Access Point
• Mounting bracket and hardware
• One Weatherproof Category 5 network cable
• One Weatherproof Console to RS232 cable
• PoE power injector/ Ethernet connector and AC power cord
• One grounding screw, not attached
•This Quick Start Guide
• One CD-ROM containing the Setup Wizard software and User’s Manual
• One Warranty Flyer
• Optional: One N-type RF coaxial cable
2 Preparing for Installation
It is advisable to connect and check the PoE connection, Ethernet cables, and LEDs before installing the
bridge in a hard-to-reach location. Additionally, observe the following items before mounting or
connecting the bridge:

3 Mounting the Bridge
The bridge can be mounted on the following types of surfaces:
•Pole
•Wall
.
CAUTION: The bridge is intended for outdoor use only. Do not install the bridge indoors.
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.)

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:
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.
1 Always attach the bracket to a wall with the flat side flush against the wall (see following
figure).
