powered off.

Application scenarios:

To ensure proper heat dissipation of the RRU, the following requirements must be met:

l The RRU cannot be installed in an enclosed cabinet without a cooling system.

l The RRU cannot be installed in an enclosed camouflage box.

l The RRU cannot be installed in an enclosed equipment room without a cooling system.

l When multiple RRUs are installed in centralized mode, the minimum clearance

requirements must be met. For details about the minimum clearance requirements, see 3.5.2

Clearance for Three or More RRUs and 3.5.3 Installation Spacing Between RRUs.

l RRU mounting kits in assembled installation mode are not allowed in indoor scenarios.

NOTICE

If the RRU is inappropriately installed, heat dissipation of the RRU deteriorates and the RRU may not work properly, as shown in Figure 3-5.

Issue () Huawei Proprietary and Confidential

3 Information About the Installation

Figure 3-5 inappropriately installed RRU

Correct installation methods:

l The installation supports' specifications described in this document are only based 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.

l 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 Figure 3-6.

l 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 multiple RRUs to be installed next to each other at the same level on a pole. When the horizontal distance between the main and auxiliary poles on a tower is equal to or greater than 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.

3 Information About the Installation

NOTICE

l 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.).

l When the diameter of a pole ranges from 60 mm (2.36 in.) to 76 mm (2.99 in.), a maximum

of three RRUs can be installed on the pole and the side-mounted installation is recommended. The RRU installation in standard mode is not recommended.

l Only a pole whose diameter ranges from 76 mm (2.99 in.) to 114 mm (4.49 in.) supports

more than three RRUs.

l The recommended thickness of the pole wall is 3.5 mm (0.14 in.) or above.

Installing an RRU on a Wall

The wall for installing RRUs must meet the following requirements:

l For each RRU, the wall must be able to bear a weight four times heavier than the RRU's

weight and the bolts' pulling force of 1.25 kN (281.25 lbf) vertical to the wall.

l Expansion bolts must be tightened to 30 N•m to ensure that the bolts work properly and

the wall remains intact.

NOTICE

l The standard installation is recommended for RRUs installed on a wall.

l When RRUs are installed on a wall in side-mounted mode, do not combine mounting brackets

for multiple RRUs, as shown in Figure 3-17.

3 Information About the Installation

Installing an RRU on an IFS06

l The upper and lower adjustable beams on an IFS06 can be moved up and down to fit for

heights of RRUs.

l The IFS06 supports at least three RRUs when the ambient temperature is higher than or

equal to the lowest operating temperature of the RRUs and at least 5°C (41°F) lower than the highest operating temperature of the RRUs. The IFS06 supports a maximum of six RRUs when the ambient temperature is higher than or equal to the lowest operating temperature of the RRUs and at least 10°C (50°F) lower than the highest operating temperature of the RRUs.

NOTE

For details about the operating temperature of the RRUs, see section "Technical Specifications of RRUs" in 3900 Series Base Station Technical Description.

NOTICE

The mounting brackets for multiple RRUs cannot be combined when the RRUs are installed on an IFS06, as shown in Figure 3-19.
