Onsite personnel must be qualified and trained. Before performing any operation, onsite
personnel must be familiar with correct operation methods and safety precautions.
Before the installation, pay attention to the following items:
lThe customer's technical engineers must be trained by Huawei and be familiar with the
proper installation and operation methods.
lThe number of onsite personnel depends on the engineering schedule and installation
environment. Generally, only three to five onsite personnel are necessary.

options and installation clearance requirements.
3 Information About the Installation
3.1 RRU Exterior
This section describes the exterior and dimensions of an RRU.
3.2 RRU Ports
This section describes ports on the RRU panels. An RRU has a bottom panel, cabling cavity
panel, and indicator panel.
3.3 RRU Indicators
This section describes six indicators on an RRU. They indicate the running status.
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.
3.5 Installation Clearance Requirements of an RRU
This section describes the requirements for the installation clearance of a single RRU and
multiple RRUs and the requirements for the installation spacing between RRUs.

You can obtain the RRU frequency band and power supply information from the
configuration label on the cover plate and obtain the RRU name from the nameplate on the
side of RRU that accommodates the conversion bracket. Figure 3-3 shows the positions of the
configuration label and nameplate on the RRU.

Alarms are generated. The alarms may be
caused by the faults on the related boards or
ports. Therefore, you need to locate the
fault before deciding whether to replace the
module.

To ensure proper heat dissipation of the RRU, the following requirements must be met:
lThe RRU cannot be installed in an enclosed cabinet without a cooling system.
lThe RRU cannot be installed in an enclosed camouflage box.
lThe RRU cannot be installed in an enclosed equipment room without a cooling system.
lWhen 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 Clearances for Three or More RRUs and 3.5.3 Installation Spacing Between
RRUs.
lRRU mounting kits in assembled installation mode are not allowed in indoor scenarios.
NOTICE
If the RRU is improperly installed, heat dissipation of the RRU deteriorates and the RRU may
not work properly, as shown in Figure 3-5.
3 Information About the Installation
Figure 3-5 Improperly installed RRUs
Method of installation:
lThe 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.
lTo 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 3-6.
lOn 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
Issue 10 (2015-12-30)Huawei Proprietary and Confidential
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.

lThe upper and lower adjustable beams on an IFS06 can be moved up and down to fit for
heights of RRUs.
lThe IFS06 supports at least three RRUs when the ambient temperature is higher than or
equal to the lowest operating temperature of the RRU and at least 5°C (41°F) lower than
the highest operating temperature of the RRU. The IFS06 supports a maximum of six
RRUs when the ambient temperature is higher than or equal to the lowest operating
temperature of the RRU and at least 10°C (50°F) lower than the highest operating
temperature of the RRU.
NOTE
For details about the operating temperature of the RRU, 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 3-16.
