7.2.2.3.4 Installation Scenarios
An RRU can be installed on a pole, U-steel, angle steel, wall, or IFS06. Installation scenarios must
meet heat-dissipation and waterproofing requirements of the RRU.
•Requirements for the Installation Scenarios
•Installing an RRU on a Pole
•Installing an RRU on U-Steel
•Installing an RRU on Angle Steel
•Installing an RRU on a Wall
•Installing an RRU on an IFS06
Requirements for the Installation Scenarios
NOTICE:

RRU is a professional communications equipment and cannot be installed in areas which are
accessible to people. The installation scenarios involve the related security features. For details
about specific requirements and precautions, see Safety Information.
Application scenarios:
To ensure proper heat dissipation of the RRU, the following requirements must be met:
•The RRU cannot be installed in an enclosed cabinet without a cooling system.
•The RRU cannot be installed in an enclosed camouflage box.
•The RRU cannot be installed in an enclosed equipment room without a cooling system.
•When multiple RRUs are installed in centralized mode, the minimum clearance requirements
must be met. For details about the minimum clearance requirements, see Clearance for Three or More
RRUs and Installation Spacing Between RRUs.
NOTICE:
If the RRU is inappropriately installed, heat dissipation of the RRU deteriorates and the RRU may
not work properly, as shown in Figure 1.
Figure 1 Inappropriately installed RRU
Installation restrictions:
•The specifications of installation supports described in this document are based only on the
exterior and dimensions of the mounting kits. Before installing equipment, assess the strength
and reliability of the installation support to determine whether it can bear the weight of the
equipment.
•To ensure the heat dissipation of the RRU and waterproofing of the ports at the bottom of the
RRU, the vertical deviation angle of an RRU must be less than or equal to 10 degrees, as shown
in Figure 2.
•On a tower, an RRU can be installed on a pole, angle steel, or U-steel. The side-mounted
installation mode (one side instead of the rear of an RRU is mounted on the support) is
recommended for RRUs on the main pole secured on a tower. This installation mode allows the

RRU stacked installation. When the horizontal distance between the main and auxiliary poles on
a tower is greater than or equal to 810 mm (23.62 in.), the side-mounted mode is recommended
for installing RRUs on the auxiliary pole to meet the minimum clearance requirements.
Otherwise, the standard mode is recommended for installing RRUs on the auxiliary pole.
•RRU stacked installation is not allowed in indoor scenarios.
•RRU stacked installation is allowed only when installed on one or more poles in outdoor
scenarios, and a maximum of three RRUs can be stacked installation.
•The periphery of RRU5309w external antennas should avoid metal shielding (such as wirelines
of the cable tower, metal fence, ground bar, and billboard).
Figure 2 Requirements for the vertical deviation angle of an RRU
(1) RRU
(2) Installation support (pole, U-steel, angle steel, or wall)
NOTE:
•When the operator faces the RRU whose handle and cabling cavity are on the right-hand side, the side facing the
operator is the front of the RRU, and the other side is the back of the RRU.
•Standard installation: RRU mounting kits are installed on the back of an RRU.
•Reverse installation: RRU mounting kits are installed on the front of an RRU.
•Side-mounted installation: RRU mounting kits are installed on the side face (not the side face of the maintenance
cavity) of an RRU.
•Stacked installation: Two or more RRUs are installed next to each other at the same level by stacking multiple RRU
mounting kits.
Installing an RRU on a Pole
Figure 3 shows the diameter of a pole for installing an RRU.
Figure 3 Diameter of a pole

NOTICE:
•The diameter of a pole for installing an RRU ranges from 60 mm (2.36 in.) to 114 mm (4.49 in.).
The recommended diameter is 80 mm (3.15 in.).
•The recommended thickness of the pole wall is 3.5 mm (0.14 in.) or above.
•When RRUs are installed on a pole, the side-mounted installation is recommended. A maximum
of three RRUs can be installed on a pole with the diameter ranging from 60 mm (2.36 in.) to 76
mm (2.99 in.).
•Only a pole whose diameter ranges from 76 mm (2.99 in.) to 114 mm (4.49 in.) supports more
than three RRUs.
Figure 4 shows a single RRU installed on a pole.
