2. Connect Ethernet cables
An Ethernet cable must be connected between the A2 Ethernet port
and the Power over Ethernet (PoE) Output port. The PoE AC Adapter
supplies the power to A2.
Another Ethernet cable (RJ –45 Straight Cable) must be connected
between the PoE Input Port and the computer or backhaul link.

7. Ethernet cable waterproof protection
1) Start wrapping a layer of electrical tape from 2” (50mm) below the edge of
the cable connector. Overlap the tape to half –width. The tape should cover
the cable connector body and the cable connector clamping nut.
2) The tape can be applied in one or more strips if necessary. A strip can be
coiled onto an applicator such as a pencil. Apply only enough tension to get
good adhesion and keep the tape smooth.
3) Start wrapping a layer of butyl rubber tape from 1” (25mm) below the edge
of the cable connector. Overlap the tape to half –width. Take extra care to
make sure that the cable connector-A2 Ethernet port junction is tightly
sealed. Press the tape edges together so that there are no gaps. Press the
tape against the cable connector body and the Ethernet port.
4) Start wrapping a layer of electrical tape from 1” (25mm) below the edge of
the cable connector. Overlap the tape to half –width.

1. For both unused RF ports, retain the RF caps on the ports.
2. Start wrapping a layer of butyl rubber tape from the bottom of RF port. Overlap
the tape to half –width. Take extra care to make sure that the RF port and the RF
cap are tightly sealed by the tape. Press the tape edges together so that there
are no gaps.
3. Start wrapping a layer of electrical tape the base of the RF port. Overlap the
tape to half –width.
2.6. General Antenna and Safety Recommendations
Please follow these safety recommendations while installing an antenna:
For safety reasons, never touch a high-gain antenna or point it at any part
of your body when it is in operation.
Follow the instructions come with your antenna manual.
Keep antennas away from metal objects and obstructions (heating and air-
conditioning ducts, large ceiling trusses, building superstructures, and major
power cabling runs).
Utilize built-in +16dBi patch antenna to establish a link between two
buildings.
Locate a pair of omni-directional antenna in the middle of the desired
coverage area if possible.
Outdoor antennas should be mounted at a sufficient height to prevent the
radio path from being blocked by obstructions such as trees and buildings.
Antenna towers should keep a safe distance from overhead power lines.
Recommended twice distance of the tower height.
Use proper ground kits and follow national safety regulation to properly
ground outdoor antenna and tower.
Ensure proper sealing on antenna cable and all external cable connecter
using waterproofing product (e.g.: coax compatible electrical tape and
coax-seal) to prevent water ingress.

2.7. 5GHz Antenna Alignment LED
When A2 WiFi Access Point/Bridge utilizes the built-in +16dBi patch antenna to
establish a bridge, then antenna should be aligned manually. Both vertical and
horizontal beamwidth of built-in +16dBi patch antenna are approximately between
25 to 30 degrees.
A2 can be configured to show the signal strength using two LED lights.
When the signal is weak, the lower light will be off. When the signal strength exceeds
the highest level configured in the web interface, the lower light will be solid on.
When the signal strength is intermediate, the lower light will blink about every five
seconds.

2.8. Grounding A2 WiFi Access Point/Bridge
It is essential to properly ground all equipment to prevent the A2 from the electrical
damage and possible electric hazer due to non-proper power grounding. Use a
10AWG grounding wire to connect to the ground connector of the A2 WiFi Access
Point/Bridge by screw driver. Secure the grounding screw tight and the strap
connects to the ground (Please refer to 错误!未找到引用源。3 for the position of
Grounding point of A2).
It is recommended that the A2 WiFi Access Point/Bridge should be installed with
lightning rod to avoid any potential electrical damage and to be connected with the
ground node to the existing ground. Proper grounding will always be the safety
consideration for the A2 WiFi Access Point/Bridge.
Note: Grounding kits are not provided in the package.
2.9. Surge Protection
The type of Ethernet cable to be used in outdoor deployment is critical. The Ethernet
cable should be either CAT5 or CAT5e, outdoor rated, and shielded. Specifically, the
following types of Ethernet cable should be used for outdoor installation: sFTP, FTP, or
STP.
Using UTP Ethernet cable and / or unshield RJ-45 jack are not recommended due
to the increased electromagnetic noise level for outdoor deployment. Furthermore,
using shielded CAT5 Ethernet cable without using shielded RJ45 jack at the base
station and PoE injector may cause more problems than not using it. This is because if
a shielded CAT5 Ethernet is ungrounded, it will act as a magnet for static charges
present in the environment. Since the charges cannot be discharged properly
through a shielded RJ45 jack, it may couple with the internal data or power lines of
the PoE cable. As a result, the coupling of high voltages present on the Ethernet
cable may damage the base station directly interfacing with it. Therefore, it is
important to always use shielded outdoor rated Ethernet cable together with shielded
RJ45 jack in outdoor deployment.
The only difference between crimping an UTP cable and a FTP cable is that the
latter has a small wire under the foil. This wire (preferably 2cm longer than other wires),
also known as the drain wire, should be wrapped around the outside of the shield
when installing the shielded RJ45 plug. It is very important to have direct contact
between the foil and the shield of the RJ45 connector.
The following figure shows a shielded, metal-enclosed RJ45 connector. First the
boot is slid onto the cable, then the cable shield and drain wire are folded back, next
the load bar is loaded with the eight inner cable conductors, then the load
