7.2.6 Basic Antenna Alignment
When you use directional antennas to communicate between two bridges,
you must manually align the antennas for proper bridge operation. Directional
antennas have greatly reduced radiation angles. The radiation angle is
approximately 25 to 30 degrees, and the parabolic dish antennas radiation angle
is approximately 12.5 degrees.
You can use the link-testing tool to help measure the alignment of two
antennas after the bridges are associated. The link-testing tool provides you
information you can use to gauge the alignment.
7.2.7 ESD Protection
The ESD (electrostatic discharge) can damage the electronic components.
The ESD can cause latent damage that results in premature failure even if
components remain function.
The equipments must be properly grounded.
The technical people always need to wear the proper ESD grounding straps and
make sure the ESD grounding strap connecting to the ESD connector during
equipment installation, maintenance and repairs.
7.2.8 Review the Installation
When you finish installing the bridges and aligning the Antennas, you need to
secure all cable connection is tight properly.
z
Secure the Antenna mounting set is tight
after the alignment.
z
Check the cable connection is between the Antenna and the bridge is tightly.
z
Make sure the grounding strip is properly connected to the Ground.
z
Check the cable to POE adapter is connected correctly.
z
Make sure the cable from the PC or the notebook to the POE adapter is
connected appropriately.
z
Make sure the POE adapter’s light is on.
z
Make sure you use the right cables during the installation.
z
Make sure all connectors are sealed with the waterproof seal.
z
Configure the ODU with the setting you want before the field installation.
z
Check if the both side bridges having the same radio settings.
z
Make sure you set up the both MAC address on each side
After taking all of these checks, you need to use the Web UI to test the
link quality and to see if the RSSI value is in the right value range. You
might need to do the Antenna alignment again if the performance is not good
enough.
