Stacking Bridges
Step 5
Slowly tilt the bridge up and down, and watch for peaks in signal strength. Use the full vertical
adjustment range of the mounting brackets.
adjustment range of the mounting brackets.
Step 6
Return the bridge to the position where the signal level is strongest.
Step 7
Secure the vertical adjustment by tightening the four bolts that secure the housing bracket to the support
bracket. Torque bolts to 14 to 16 ft. lb.

Step 8
Remove the cable from the RSSI port and replace the cover.
Stacking Bridges
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.

Operations summary:
•
Adjacent bridges should be located at least 8 feet apart.
•
Radios of adjacent bridges should be configured for operation on non-adjacent channels.
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 feet. 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.
