2.3 Installation Instructions
The following instructions assume that you are installing the
Fortress Bridge with the minimum number of possible changes
to its default configuration:
The Fortress Bridge will operate in Normal operating mode.
Radio 1 will be used, in the 802.11g band, as a WLAN
access point (AP) for wireless devices within range, and it
will transmit and receive on channel 1.
Radio 2 will be used for bridging in a point-to-point or point-
to-multipoint deployment of multiple Fortress Bridges, and it
will transmit and receive on channel 149, with a distance
setting of 1 mile.
STP (Spanning Tree Protocol) is enabled on the Bridge,
and Multicast is enabled on the non-root Bridge(s).
In indoor deployments, the Bridge’s internal LAN switch will
be used to connect a local area network.
Complete configuration guidelines, covering the full set of
Fortress Bridge functions and options, are provided in Chapter
3, Configuration.
Procedures differ between indoor and outdoor installations.
Refer to the instructions that apply to your deployment.
NOTE: Third par-
ty antennas are
subject to local regulato-
ry requirements. For
outdoor installations,
they must be water-
proof.
2.4 Outdoor Installation
When installing the Fortress Bridge outdoors, you must use the
Mast-Mounting Kit and the Weatherizing Kit—both included in
every shipment—to mount and weatherize the Bridge.
When the Weatherizing Kit is installed, the only available
connections to the Bridge are the front-panel WAN port and the
rear-panel antenna ports.
Before installing the Bridge in a hard-to-reach, outdoor
location, Fortress recommends connecting and preconfiguring
the Bridge.
