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. An inappropriate ambient environment reduces the heat dissipation efficiency and an RRU may not work properly, as shown in Figure 3-5. Figure 3-5 Inappropriate ambient environment Installation Mode 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. 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 3-6. Issue 05 (2017-03-10) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 12 RRU3278 Installation Guide 3 Information About the Installation An RRU can be installed on a pole, U-steel, or angle steel on a tower. The side-mounted installation mode is recommended for the RRU on the main pole secured on a tower. This installation mode allows multiple RRUs to be centrally installed. If 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 installation mode is recommended for installing the RRU on the auxiliary pole. Otherwise, the standard installation mode is recommended for installing the RRU on the auxiliary pole. Figure 3-6 Requirements for the vertical deviation angle of an RRU 1. RRU 2.

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. Issue 05 (2017-03-10) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 58 RRU3278 Installation Guide Outdoor Cabling Requirements 8 Installing RRU 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 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. 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), CPRI 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 CPRI 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 05 (2017-03-10) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 61 RRU3278 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 05 (2017-03-10) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 62 RRU3278 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 with force. When coiling fiber optic cables, apply even strength. Do not bend the fiber optic cables 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.
