Hardware Installation
•
Connector: Make sure you choose the correct connection type. is, for example N-Type, SMA Male/Female.
Antenna Alignment
Use the following procedure to align your antenna.
1.
Follow the antenna installation guide to install the antenna properly.
2.
Connect your laptop to the Ethernet port and if necessary, install a Cellular Speed Test utility on your
laptop or connect to the carrier provider’s web page, as some carriers provide an utility on their web site.
3.
Adjust the antenna location, run the Speed Test utility to check the result after changing the location or
direction.
Lightning Arrestor
If you install an external antenna in outside area, we recommend installing a lightening arrestor to avoid an
environment attack through the antenna. A lightening arrestor protects the insulation and conductors of the
system from the damaging effects of lightning.
Note:
Before installing an external antenna, make sure that the antenna can support a 3G connection. Most of
the high gain external antennas are installed in higher place than the AP, you should get a low power
loss antenna cable in advance. If installing the AP in a metal field box, connect an extended antenna
cable to outside the box to avoid the Radio lost.
Connect the Power
The following table provides WR7802-XT electrical specifications.
The WR7802-XT supports redundant power supplies if you connect both PWR1 and PWR2. The WR7802-XT
accepts a positive power source. If both power inputs are connected, the WR7802-XT is powered from the
highest connected voltage. The WR7802-XT does not support reverse polarity protection.
The DC power circuit of the WR7802-XT is not an isolated design circuit. In practice, we recommend using an
isolated DC power design PSU for field installations. Do not power on the WR7802-XT without an appropriate
PSU and following proper grounding methods.
Note:
Power should be disconnected from the power supply before
connecting it to the WR7802-XT. Your screw driver blade can
inadvertently short the terminal connections to the grounded
enclosure.
Use the following procedure to connect the power to the WR7802-XT.
1.
Connect the DC power inputs by inserting the positive and negative
wires (12-16AWG) into the PWR+ and PWR- contacts using the
following wiring drawing.
Note:
Tighten the wire-clamp screws to prevent the wires from coming loose.
