Installation scenarios must meet heat-dissipation and waterproofing requirements of the RRU. Requirements for the Installation Scenarios 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 3.5.2 Clearance for Three or More RRUs and 3.5.3 Installation Spacing Between RRUs. If the RRU is inappropriately installed, heat dissipation of the RRU deteriorates and the RRU may not work properly, as shown in Figure 3-4. Issue Draft B (2018-05-15) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 10 RRU5303 Installation Guide Figure 3-4 Inappropriately installed RRU 3 Information About the Installation Installation restrictions:
The specifications of installation supports 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. If an AC RRU consists of an 18 L blade RRU and an OPM15M(Ver.B), this AC RRU cannot be installed in side-mounted mode. 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 3-5. 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.

(2) Installation support (pole, U-steel, angle steel, or wall) 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 3-6 shows the diameter of a pole for installing an RRU. Figure 3-6 Diameter of a pole Issue Draft B (2018-05-15) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 12 RRU5303 Installation Guide 3 Information About the Installation 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

If a cable listed below is not required, skip the cabling requirements of the cable. General Cabling Requirements Bending radius requirements The bending radius of a 7/8'' feeder must be greater than 250 mm (9.84 in.), and the bending radius of a 5/4'' feeder must be greater than 380 mm (14.96 in.). The bending radius of a 1/4'' jumper must be greater than 35 mm (1.38 in.). The bending radius of a super-flexible 1/2'' jumper must be greater than 50 mm (1.97 in.), and the bending radius of an ordinary 1/2'' jumper must be greater than 127 mm (5 in.). The bending radius of a power cable or PGND cable must be at least three times its diameter. The bending radius of a fiber optic cable is at least 20 times of its diameter, and the bending radius of a breakout cable is at least 30 mm (1.18 in.). The bending radius of an E1/T1 cable must be at least three times its diameter. The bending radius of a signal cable must be at least five times its diameter. Cable binding requirements Cables of the same type must be bound together. Different types of cables must be separately laid out and bound, with a minimum distance of 30 mm (1.18 in.) from each other. The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged. The cable ties must face the same direction, and those at the same horizontal line must be in a straight line. The excess of the indoor cable ties is cut off. The excess of 5 mm (0.197 in.) of the outdoor cable ties is reserved, and the cut surfaces are smooth without sharp edges. After cables are installed, labels or nameplates must be attached to the cables at their ends, curves, and interconnection positions. Security requirements When routing cables, avoid sharp objects, for example sharp edges on the wall. If necessary, use tubes to protect the cables. When routing cables, keep the cables away from heat sources and use heat insulation materials to insulate the cables from the heat sources. Reserve a proper distance (0.1 m or 3.937 in. is recommended) between equipment and cables especially at the cable curves to protect the cables and equipment. Indoor cabling requirements Issue Draft B (2018-05-15) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 87 RRU5303 Installation Guide 8 Installing RRU Cables Route each cable into the room through the feeder window. Reserve drip loops for all cables outside the feeder window before routing them into the room. Ensure that the radiuses of the drip loops are greater than or equal to the minimum bending radiuses of the cables. When routing a cable into the room, ensure that a person is assisting you in the room. Apply waterproof treatment to the feeder window. Outdoor Cabling Requirements After being connected to a ground clip on power cables, a ground cable must be routed downwards to prevent water from entering the equipment to which the power cables connect. Protect outdoor cables against potential damage. For example, put the cables through tubes. The cables to be protected include AC power cables, transmission cables, and cables laid out underground. When routing cables through tubes on the ground below the cabinet, put a 30 mm to 50 mm (1.18 in. to 1.97 in.) length of the tubes into the base of the cabinet but do not put the tubes into the cabinet. Use waterproof tape or waterproof silicon gel to block both ends of the tubes and use sheet metal tabs to secure the tubes to the cable holes in the base. When routing cables through tubes along a metal cable trough below the cabinet, do not put the tubes into the base of the cabinet but cover the cable trough and connect the tubes to the cable holes in the base. When routing RRU cables, ensure that the highest positions of the routes of all RRU cables (except RF cables and AISG cables) are lower than the bottom of the RRU to prevent water from entering the maintenance cavity of the RRU. Use clips to secure cables outdoors. For the method of installing a clip, see the installation guide delivered with the clip. Arrange cables neatly along the routing direction and use clips to secure the cables. Determine the positions where the clips are installed according to the actual situation. For example, 7/8" feeders are secured with clips at an interval of 1.5 m to 2 m (4.92 ft to 6.56 ft), CPRIIr fiber optic cables and power cables are secured with clips at an interval of 1 m to 1.5 m (3.28 ft to 4.92 ft). Ensure that the clips are evenly spaced and in the same direction. When fastening cables with a clip, ensure that the cables are aligned neatly and are routed through the holes in the clip. Do not stretch the cables too tightly. There are two types of clips: 3-hole clip and 6-hole clip, which are described as follows:
A 3-hole clip is shown by illustration a in the following figure. It is often used to fasten feeders. A 6-hole clip is shown by illustration b in the following figure. It is often used to fasten power cables and CPRIIr fiber optic cables.

If the length of power cables is insufficient, replace the cables rather than adding connectors or soldering joints to lengthen the cables. Cables can only be laid out under well-planned instructions. The cabling activities of fiber optic cables are allowed only when qualified personnel and communication facilities are available. Do not circle and twist cables. Issue Draft B (2018-05-15) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 90 RRU5303 Installation Guide 8 Installing RRU Cables After routing a DC power cable onto the platform on a tower, route it along the shortest path to the rails surrounding the platform, and route it along the inside of the rails. After routing a DC power cable close to the equipment on a tower, use clips to secure the power cable onto a pole or the rails surrounding the platform. Ensure that there is no excessively long distance between the equipment and the position where the power cable is secured. Cabling of PGND cables PGND cables for a base station must be connected to the same group of ground bars. PGND cables must be buried in the ground or routed indoors. The external conductor of the coaxial wire and the shield layer of the shielded cable must have proper electrical contact with the metal surface of the equipment to which they are connected. PGND cables and signal cables must be installed separately. A certain distance must be reserved between them to prevent interference from each other. Switches or fuses must not be installed on the PGND cables. Other devices must not be used for electrical connections of the PGND cables. All the metal parts in the housing of the equipment must be reliably connected to the ground terminal. Cabling of E1 cables E1 cables must not cross power cables, PGND cables, or RF cables when laid out. If transmission cables are laid out with power cables, PGND cables, or RF cables in parallel, the spacing between them must be greater than 30 mm (1.18 in.). E1 cables are lined up straight and bound neatly with cable ties. Sufficient slack is provided for E1 cables at turns. E1 cables must not be pressed by the door of the cabinet when routed, as shown in the following figure. Figure 8-4 E1 cables routed in the cabinet Cabling of fiber optic cables At least three people are required for laying out fiber optic cables. The cabling activities of fiber optic cables are allowed only when qualified personnel and communication facilities are available. Issue Draft B (2018-05-15) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 91 RRU5303 Installation Guide 8 Installing RRU Cables The operating temperature of fiber optic cables ranges from -40C to +60C (-40F to
+140F). If the actual temperature is beyond this range, take protective measures or select another route. Do not circle and twist cables. Do not bind a fiber optic cable at the position where it bends. Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the fiber optic cables away from sharp objects. When fiber optic cables are routed, the excess of the fiber optic cables must be coiled around special devices, such as a fiber coiler. An unarmored fiber optic cable must be bound using binding straps. If a fiber optic patch cord needs to be secured in a cabinet or a piece of equipment, use binding straps to bind it and then use cable ties to secure the binding straps to the cabinet or equipment. Ensure that the fiber optic cables can flexibly move in the cable ties. Do not bend the fiber optic cables sharply. The following figure shows how to bind the fiber optic cables correctly. Figure 8-5 Binding fiber optic cables When coiling fiber optic cables, apply even strength. Do not bend the fiber optic cables with force. Unused optical connectors must be covered with dustproof caps. The fiber optic cables must not be pressed by the door of the cabinet when routed, as shown in the following figures.

----End 8.9 Installing a CPRI Optical Fiber This section describes the procedure for installing a CPRI optical fiber. Prerequisites Before the installation, single-mode optical modules can be distinguished from multimode optical modules in either of the following ways:
SM and MM labels on an optical module: SM indicates a single-mode optical module, and MM indicates a multimode optical module. Color of the puller on an optical module: Blue indicates a single-mode optical module, and black or gray indicates a multimode optical module. Issue Draft B (2018-05-15) Huawei Proprietary and Confidential 110 Copyright Huawei Technologies Co., Ltd. RRU5303 Installation Guide 8 Installing RRU Cables The optical modules to be installed must match CPRI rates. Context A CPRI optical fiber transmits CPRI signals between a BBU and an RRU. The performance of an optical module may deteriorate if it is exposed to the air for a long time. Therefore, after installing the optical module and before connecting the optical fiber, keep the dustproof cap in the port of the optical module. The CPRI optical cables must be correctly connected in one time during the installation. Otherwise, the RRU may become faulty, causing cells to fail to provide services. Procedure Step 1 Lower the pullers of two optical modules, insert one optical module into the CPRI0 port on the RRU and the other optical module into the CPRI port on the BBU, and raise the pullers, as shown in Figure 8-25. Figure 8-25 Installing an optical module Step 2 Install CPRI optical fibers. Issue Draft B (2018-05-15) Huawei Proprietary and Confidential 111 Copyright Huawei Technologies Co., Ltd. RRU5303 Installation Guide 8 Installing RRU Cables After removing dustproof caps from the optical module and optical fiber connector, insert the optical fiber into the optical module immediately (within one minute) to avoid pollution of the optical module or optical fiber connector, which may cause an optical module alarm. Ensure that CPRI optical fibers are correctly connected before the RRU is powered on. Otherwise, the RRU may become faulty, causing cells to fail to provide services. To avoid any damage to optical fibers, the fibers connected to the RRU must be installed according to the installation process. For details about the installation process, see 8.3 Installing RRU Cables. When installing CPRI optical fibers for dual-fiber bidirectional optical modules, remove the dustproof caps from the ports on the optical module and those from the optical fiber connector, and connect the end labeled 1A and 1B on the optical fiber to the optical modules on the RRU side, as shown in Figure 8-26. Connect the DLC ends labeled 2A and 2B to the CPRI port on the main control board (such as the GTMU) or baseband processing board (such as the WBBP) in the BBU. Figure 8-26 Installing CPRI optical fibers for dual-fiber bidirectional optical modules When installing CPRI optical fibers for single-fiber bidirectional optical modules, remove the dustproof caps from the ports on the optical module and from the LC end labeled 1A on the optical cable, divide the DLC end into two LC ends, and connect the end labeled 1A to the optical module on the RRU side, as shown in Figure 8-27.
