----End 6 Installing the DRH 6.6 Installing a DRH on an IFS06 This section describes the procedure and precautions for installing a DRH on an IFS06. Prerequisites The hoist clamp on the main bracket is secured properly. Context Do not stand the DRH upright because the RF ports cannot support the weight of the DRH. Place a foam pad or cardboard under a DRH to protect the DRH housing from damage during the installation. The upper and lower adjustable beams on an IFS06 can be moved up and down to fit for heights of DRHs. DRHs can be installed on an IFS06 only when the ambient temperature is higher than or equal to the lowest working temperature of the DRH and at least 5C (41F) lower than the highest working temperature of the DRH. In this scenario, the IFS06 supports at least three DRHs. When the ambient temperature is higher than or equal to the lowest working temperature of the DRH and at least 10C (50F) lower than the highest working temperature of the DRH, the IFS06 supports a maximum of six DRHs. Install DRHs in the sequence from bottom to top and from left to right. This section describes how to install a DRH in height-unrestricted scenarios. The procedure for installing a DRH in height-restricted scenarios is the same as that in height-unrestricted scenarios. When installing the main bracket, you need to use the M10x50 bolts delivered with the IFS06. Rubber washers are easily compressed or broken, whereas do not need to be replaced.

If a cable listed below is not required, skip the routing requirements of the cable. General Cabling Requirements Requirements for Bending Radius The bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bending radius of the 5/4'' feeder must be more than 380 mm (14.96 in.). The bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bending radius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bending radius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.). The bending radius of the power cable or PGND cable must be at least three times the diameter of the cable. The bending radius of a fiber optic cable is at least 20 times the diameter of the fiber optic cable, and the minimum bending radius of the breakout cable at each end of the fiber optic cable is 30 mm (1.18 in.). The bending radius of the signal cable must be at least five times the diameter of the cable. Requirements for Cable Binding The same types of cable must be bound together. Different types of cable must be separately routed with the minimum spacing of 30 mm
(1.18 in.) and cannot be entangled. The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged. Cable ties are installed in the same direction, and those at the same horizontal line must be in a straight line. The excess of indoor cable ties is trimmed off, and the excess of outdoor cable ties allows about 5 mm (0.2 in.), without remaining rough edges. Labels or nameplates must be attached to both ends, joints, or turns of cables after they are installed. Security Requirements Cables should be placed away from sharp objects or wall burrs. If these positions are inevitable, protect the cables with protection pipes. Cables must be routed away from heat sources, or heat-insulation materials are added between cables and heat sources. Sufficient slack (recommended for about 0.1 m [0.33 ft]) is provided in cables at turns or the position close to a device, facilitating cable and device maintenance. Indoor Cabling Requirements Issue Draft A (2013-09-16) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 63 DRH3985A&3917A&3919A Installation Guide 7 Installing DRH Cables Cables are routed indoors through the feeder window. Drip loops must be made outside the feeder window, and the requirements for the minimum bending radius are met. When cables are routed indoors, engineers are required indoors for cooperation. The feeder window must be waterproofed. Outdoor Cabling Requirements Cables routed outdoors must be led through a pipe when they may be damaged. AC power cables, transmission cables, and cables buried in the ground must be protected. If cables at the cabinet bottom need to be routed through a pipe along the ground, lead the pipe into the cabinet base for about 30 mm (1.18 in.) to 50 mm (1.97 in.), not into the cabinet. Block the pipe with waterproof tape or silicon gel, and secure the pipe to the cable hole at the cabinet bottom with metal piece. If cables at the cabinet bottom need to be routed through a pipe along the metal cable trough, do not lead the pipe into the cabinet base. The cable trough must be sealed and routed through the cable hole at the cabinet bottom. When routing DRH cables, ensure that the highest positions of the routes of all DRH cables (except RF cables and AISG cables) must be lower than the bottom of the DRH. Cables are secured with cable clips. Cables are routed neatly along the specified cabling direction and secured with cable clips. The positions for cable clips are determined onsite. For example, the cable clips for the 7/8" feeder are installed at the spacing of 1.5 m (4.92 ft) to 2 m (6.56 ft) in the same direction, and the cable clips for the power cables are installed at the spacing of 1.5 m
(4.92 ft) to 2 m (6.56 ft) in the same direction. Cable clips must be vertical with cables, and the cables in a cable clip must be parallel. After routing cables neatly and correctly, tighten the screws on cable clips. Secure cables on the cable tray, as shown in Figure 7-1. Issue Draft A (2013-09-16) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 64 DRH3985A&3917A&3919A Installation Guide Figure 7-1 Securing cables on the cable tray 7 Installing DRH Cables 7.1.1 Special Cabling Requirements Cabling Requirements for Power Cables Power cables must be installed in the position specified in engineering design documents. If the length of power cables is insufficient, replace the cables rather than adding connectors or soldering joints to lengthen the cables. Cables must be routed by only qualified and trained personnel before all preparations are made. Cables are routed in an untangled and orderly fashion. Cabling Requirements for PGND Cables PGND cables for the base station must be connected to the same ground bar. PGND cables must be buried in the ground or routed indoors. They should not be routed overhead before they are led into the equipment room. The exterior 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 in an untangled and orderly fashion. A certain distance must be reserved between them to prevent interference from each other. Fuses or switches 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 Requirements for Fiber Optic Cables Issue Draft A (2013-09-16) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 65 DRH3985A&3917A&3919A Installation Guide 7 Installing DRH Cables Fiber optic cables must be routed by at least three qualified and trained personnel before all preparations are made. Fiber optic cables are used within the temperature range of -40C to 60C. If the current temperature is out of the range, make protection measures or route the cables again. Cables are routed in an untangled and orderly fashion. Do not bind fiber optic cables at turns. Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables away from sharp objects. When fiber optic cables are routed, the excess of the cables must be coiled around special devices, such as a fiber coiler. When coiling fiber optic cables, apply even strength. Do not bend the cables with force. Vacant optical connectors must be covered with dustproof caps. Fiber optic cables cannot be squeezed by the cabinet door when routed through the cabinet, as shown in Figure 7-2. Figure 7-2 CPRI fiber optic cables routed through the cabinet 7.2 Cable Connections This section describes the cable connections for DRHs.

The Distributed Remote Head (DRH) performs the following functions:
Receives downlink baseband data from the DCU and sends uplink baseband data to the DCU. Receives RF signals from the antenna system, down-converts the signals to intermediate frequency (IF) signals, amplifies the IF signals, and performs analog-to-digital conversion. The transmit (TX) channel filters downlink signals, performs digital-to-analog conversion, and up-converts RF signals to the TX band. Multiplexes receive (RX) and TX signals on the RF channel, which enables these signals to share the same antenna path. It also filters the RX and TX signals. The DRH can be powered by the AC/DC power module. In this case, this DRH is called AC DRH. An DRH consists of a high-speed interface unit, signal processing unit, power amplifier, and dual-duplexer. Figure 2-3 shows the logical structure of the DRH.
