Cisco Cisco Aironet 1400 Wireless Bridge 설치 가이드

With the exception of the following, no antenna alignment procedures are required:

Ensure that the antenna is installed on the azimuth and elevation data provided in the site survey.

Check to see that nothing obstructs the line of sight between the antenna and the devices to which 
it associates.

A comprehensive discussion of antenna alignment theory and procedures is contained in the Cisco 
Aironet 1400 Series Wireless Bridge Mounting Instructions.

Activate the link after the bridge system is completely installed and ready to power up. The following 
procedure summarizes the bridge activation procedure:

Power up the root bridge, observing the LEDs to verify proper startup.

Power up the remote (non-root) bridge, verify successful association, and position the antenna.

If the initial antenna positioning was reasonably accurate, both bridges initialize and quickly associate 
with one another. If the bridges do not associate, the antennas may be poorly aligned or not set for the 
same polarization, so you may need to adjust the antenna position during the bridge startup cycle. 
Persistent association problems can indicate poor placement of the bridge or obstacles in the 
transmission path.

Use LED indications to verify the state of the bridge during the association process. The following 
section explains how to interpret LED indicators.

When you power up the bridge for the first time, it starts in a special installation mode. In this mode, the 
LEDs indicate the startup status, operating mode, association status, and received signal strength. This 
information helps you activate the link and position the antenna while at the bridge mounting location. 
The LEDs are mounted on the back of the housing near the connectors (see
