Installation Guide

5. Electrostatic Discharge (ESD) Protection

Electrostatic discharge (ESD) can damage electronic components and

cause latent damage that results in premature failure even if

components remain functional. In addition, the equipment must be

properly grounded. Technicians should always wear proper ESD

grounding straps connected to the ESD connector during equipment

installation, maintenance and repairs.

6. Post Installation Procedures

Make sure that all cables are connected properly with the following

procedures after completing the A3-Ei installation and aligning the

antenna:

 Make sure the antenna is mounted tightly after the alignment

 Make sure the grounding strap is connected properly to the

ground.

 Check all cables are connected to PoE injector correctly and

properly.

o Make sure the Ethernet cable from PC or backhaul

network equipment is connected to “Data In” port of PoE

injector.

o Make sure the Ethernet cable from A3-Ei is connected to

“Data & Power Out” port of PoE injector.

 Make sure the PoE injector’s light is on.

 Make sure the right cables are used during the installation

 Make sure all connectors are sealed with the waterproof seal

properly.

After going through the above procedure, it is necessary to test the

wireless quality and check whether the RSSI fails into the acceptable

range or not via A3-Ei Web UI. It might be needed to re-aligns antenna

again if the performance is not acceptable.
