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 1300 Series Wireless Bridge Mounting Instructions that shipped with your
bridge.
Note To meet regulatory restrictions, the external antenna BR1300 configuration and the external antenna
must be professionally installed. The network administration or other IT professional responsible for
installing and configuring the unit is a suitable professional installer. Following installation, access to the
unit should be password protected by the network administrator to maintain regulatory compliance.
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 TBD ft (TBD 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 4-1 identifies
the interference paths with stacked bridges.
