Safety Precautions
This document is intended to provide guidelines for hardware quick installation.
Thunderstorm
Do not perform operations on towers or poles with high voltage and AC power
during thunderstorms.
Working at Heights
When working at heights, be careful about objects falling down from a height.
Hoisting Heavy Objects
When heavy objects are hoisted, do not stand or walk under the boom or the
objects.
Microwave
High power radio-frequency signals are harmful to human body. Do not stay too
close to the antenna in the emitting direction of the antenna when the microwave
communication equipment is working. When installing or maintaining an antenna
on the tower or pole installed with more than one antenna, avoid the strong
radiation from the other antennas.
IF Cable
Before installing or removing an IF cable, turn off the ODU power switch.

Direct Mounting Mode
Do not install the ODU under harsh weather conditions, such as windy, rainy, or stormy weather.
After the ODU is unpacked or powered off, it must be powered on within 24 hours to avoid moisture
accumulation in it.
Do not damage the coating when you install or replace an ODU.
In case of operating in the sea or around the coast area (within 3.7 km from coastline) or 3 km away
from inland pollution sources (including coal mines, metallurgic plant, thermal power plant , and chemical
plant), measure must be taken for the ODU against salt damage. Please contact HUAWEI for the
countermeasure.

Changing Polarization Direction of the Antenna
The antennas are available in multiple types. This procedure for changing the antenna polarization direction is provided for
reference only. In actual installation, follow the instructions delivered with the antenna.
By default, the antenna applies vertical polarization. If the antenna requires horizontal polarization in the network plan, the
polarization direction of the antenna should be changed.
1. Loosen the fastening screw ④on feed boom ③so that the feed boom can rotate freely.
2. Rotate the feed boom ①90 degrees in a clockwise direction or an anticlockwise direction to ensure that the red
polarization identifier on the feed boom is aligned with the H identification line.
3. Adjust feed boom ①to align the four feed booms tabs ③with the holes in the feed boom, and then tighten
fastening screw ④on the feed boom.

Installing the ODU on the Antenna
1. Observe the position of the ODU guide pin . It is attached to the inner side of the ODU handle by default.
When the antenna is installed in horizontally polarized mode, secure guide pin ①to identifier H. Before
securing the guide pin, you should screw out the plastic screw ②at identifier H. When the antenna is installed
in vertically polarized mode, secure guide pin ①to identifier V. Before securing the guide pin, you should screw
out the plastic screw ②at identifier V. The following describes how to install the guide pin for horizontal-
polarized antennas.
The guide pin is used together with the guide through to facilitate the installation of the ODU.
Apply anti-seize grease to the screws on the guide pin.
2. Remove the dust-proof caps ①from the antenna port of the ODU and the antenna feed boom.

3. Installing the ODU on the Antenna
3.1. Apply lubricant on gasket ⑥of the antenna interface on the ODU. (Note: Do not apply lubricant on end face ⑤.)
3.2. Apply anti-seize grease to the four M6 captive screws ①on the ODU.
3.3. Lift the ODU to slide guide pin ②of the ODU into guide trough③facing the antenna direction.
3.4. Install the ODU on the antenna and ensure that the IF interface ④of the ODU faces downwards.
3.5. Screw the four M6 captive screws ①on the ODU part way in and then tighten them cornerwise in sequence.

a Changing the Polarization Direction of the Hybrid Coupler
Installing the Hybrid Coupler on the Antenna
The hybrid coupler is available in multiple types. This procedure for changing the polarization direction of the
hybrid coupler is provided for reference only. In actual installation, follow the instructions delivered with the
hybrid coupler.
By default, the hybrid coupler applies vertical polarization. If horizontal polarization is required, change the
polarization direction of the hybrid coupler antenna port.
When adjusting the polarization direction of the hybrid coupler , ensure the seal washer is correctly installed
and intact.
1. Loosen the four hex socket screws ②and remove the polarizer ①. Note: Ensure that the seal washer does not
fall off during this procedure.
2. Align the arrow (↑) on the polarizer ①with the letter H on the antenna by rotating the polarizer ①.
3. Check whether the seal washer is correctly installed and intact before installing the polarizer. Then, install the
polarizer ①and tighten the four hex socket screws ②.

1. Apply lubricant on gasket ⑤of the antenna interface of the hybrid coupler. (Note: End face ④should not be
applied with lubricant.)
2. Apply anti-seize grease to the four M6 captive screws ③of the hybrid coupler.
3. Slide guide pin ②of the hybrid coupler into guide trough ①, and then install the hybrid coupler onto the antenna.
4. Screw the four M6 captive screws ③of the hybrid coupler part way in and then tighten them cornerwise.

Installing the ODU on the Hybrid Coupler
1. Replace guide pin position ①of the ODU and ensure that it is located at indicator H. Apply anti-seize grease to
the screws on the guide pin.
2 Apply lubricant on gasket ⑥of the antenna interface of the ODU. (Note: End face ②should not be applied with
lubricant.)
3. Apply anti-seize grease to the four M6 captive screws ③of the ODU.
4. Slide guide pin ①of the ODU into guide trough ④of the hybrid coupler, and then install the ODU onto the hybrid
coupler. Ensure that the IF interface ⑤of the ODU faces downwards.
5. Screw the four M6 captive screws ③of the ODU part way in and then them cornerwise.
Two ODU interfaces are available on the hybrid coupler. The main ODU must be installed on the MAIN interface of the hybrid
coupler and the standby ODU must be installed on the STD BY interface of the hybrid coupler.
