Chapter 4 Stacking Bridges

Overview

Overview

You can double the throughput, or create a standby link, by stacking two bridges. A stacked installation consists of two bridge systems installed at the same physical location. For detailed mounting instructions refer to the Cisco Aironet 1400 Series Wireless Bridge Mounting Instructions that shipped with your bridge.

Choosing a Second Mounting Location

You can mount the second bridge system in the same general location as the first as long as you separate the antennas by at least 8 ft (2.44 m). For example, in a flat-roof installation you can separate the bridges horizontally, roughly perpendicular to the line of signal propagation. In a tower installation, you can separate the antennas vertically. During the activation process, you verify that the interference between systems is acceptably low. Do not attempt to stack more than two bridges. Figure 4-1identifies the interference paths with stacked bridges.

Installing the Stacked Bridges

To install stacked bridges, refer to Figure 4-1as you follow these steps:

 

 

 

Step 1

Install the link 1 bridges (bridges A and C) normally, but leave room at each site to install the link 2

 

 

 

 

bridges (bridges B and C).

 

 

 

Step 2

Activate the link 1 bridges, align the antennas, and verify proper operation of the link.

 

 

 

Step 3

At each site location, choose a candidate location for the second bridge that is at least 8 ft (2.44 m) away

 

 

 

 

from the first bridge. Separate the bridges as far as is practical from each other, keeping in mind that the

 

 

 

 

second antenna must have a clear path to the remote system.
