The bending radius of an optical cable is at least 20 times the diameter of the optical cable, and the minimum bending radius of the branch at each end of the optical cable is 30 mm. The bending radius of the signal cable must be at least five times the diameter of the cable. Cable Binding Cables of the same type are bound together. Different types of cables must be separately routed with a minimum spacing of 30 mm and cannot be entangled or crossed. The cables are bound tightly and neatly and the cable sheath is intact. The cable ties face the same direction and all cable ties bound at similar positions must be in a straight line. The extra length of each indoor cable tie must be cut off. A slack of 5 mm is reserved for each outdoor cable tie. All cut surfaces have no sharp edges. Labels or nameplates are attached to both ends, joints, or turns of cables after they are installed. Safety Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 34 DBS3900 LampSite Installation Guide 6 Installing an RHUB The steel pipe or fire-resistant rigid polyvinyl chloride pipe should be used for the cable duct or for routing cables. The cross-sectional usage of the cable duct should be 30% to 50% and that of the pipe for routing cables should be 25% to 30%. Cables are placed away from sharp objects or wall burrs. If these positions are inevitable, protection pipes are required for the cables. Cables are routed away from heat sources, or heat-insulation materials are added between cables and heat sources. Cables are routed away the cooling vents of the RHUB. A clearance is reserved at turns of a cable or the position close to a device, facilitating cable and device maintenance. The recommended clearance is about 0.1 m. Requirements for Special Cables Ethernet Cable A maximum of 100 Ethernet cables can be bundled if no PVC pipes are used. If pipes are used, a maximum of 24 Ethernet cables can be led through a pipe. In this case, ensure that 1/3 space inside the pipes must be vacant. The point at which an Ethernet cable is bundled must be spaced 400 mm or less from the Ethernet port on an RHUB. For the RHUB used in the elevator engine room on the rooftop, generator set for the subway engine, and equipment room with central air conditioning, Ethernet cables must be led through metallic conduits that are reliably grounded at both ends. Power cable Positions for routing power cables meet requirements of the engineering design. Cables are routed only by qualified and trained personnel before all preparations are made. Cables are routed in an untangled and orderly fashion. PGND cable PGND cables are buried in the ground or routed indoors. They cannot be routed overhead before they are routed into the equipment room. Outer conductors of coaxial cables and both ends of the shield layers on shielded cables are in proper electrical contact with the metal surface of the equipment to which they are connected. PGND cables and signal cables are installed in an untangled and orderly fashion. A certain distance is reserved between them to prevent interference from each other. Fuses or switches are not allowed on PGND cables. Other devices cannot be used for electrical connections of PGND cables. All the metal parts in the equipment are reliably connected to the ground terminal. Optical cable Cables are routed in an untangled and orderly fashion. Optical fibers cannot be bound at turns. Optical fibers cannot be stretched with too much force or stepped on, and they are far away from sharp objects. Heavy objects cannot be placed on optical cables. When optical cables are routed, the extra length of the cables is coiled around special devices, such as a fiber coiler. Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 35 DBS3900 LampSite Installation Guide 6 Installing an RHUB Even strength is applied when optical cables are coiled and optical cables cannot be bent in a forcible manner. Vacant optical connectors are covered with dust-proof caps. Fiber optic cables cannot be squeezed by the cabinet door when routed through the cabinet. If optical cables need to be routed on the tower platform, the optical cables are routed along the inner side of the guard rail and the distance between the guard rail and the cable is the shortest one. If optical cables need to be routed close to a device on the tower, the optical cables are secured to the guard rail or pole with cable clips and the device cannot be far away from the position for securing the optical cables. If the optical cable close to a device on the tower is too long, the optical cables are wrapped and secured to the tower. 6.4.2 Cable List This section describes the connector types and connections of the RHUB cables.

Different types of cables must be separately routed with a minimum spacing of 30 mm and cannot be entangled. The cables are bound tightly and neatly and the sheaths of the cables is intact. The cable ties face the same direction and all cable ties bound at similar positions must be in a straight line. The extra length of each indoor cable tie must be cut off. A slack of 5 mm is reserved for each outdoor cable tie before the extra length is cut off. All cut surfaces are without sharp edges. Labels or nameplates are attached to both ends, joints, or turns of cables after they are installed. Safety The steel pipe or fire-resistant rigid polyvinyl chloride pipe should be used for the cable duct or for routing cables. The cross-sectional usage of the cable duct should be 30% to 50% and that of the pipe for routing cables should be 25% to 30%. Cables are placed away from sharp objects or wall burrs. If these positions are inevitable, protection pipes are required for the cables. Cables are routed away from heat sources, or heat-insulation materials are added between cables and heat sources. A clearance is reserved at turns of a cable or the position close to a device, facilitating cable and device maintenance. The recommended clearance is about 0.1 m. Requirements for Special Cables Ethernet Cable A maximum of 100 Ethernet cables can be bundled if no PVC pipes are used. If pipes are used, a maximum of 24 Ethernet cables can be led through a pipe. In this case, ensure that 1/3 space inside the pipes must be vacant. The point at which an Ethernet cable is bundled must be spaced 400 mm or less from the Ethernet port on a pRRU. For the pRRU used in the elevator engine room on the rooftop, generator set for the subway engine, and equipment room with central air conditioning, Ethernet cables must be led through metallic conduits that are reliably grounded at both ends. 8.4.2 Cable List This section describes pRRU3902 and pRRU3911 cable connections. pRRU3902 Cables Table 8-8 lists pRRU3902 cables.

Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 172 DBS3900 LampSite Installation Guide 9 Installing a pRRU3907 NOTE 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 (5.00 in.). The bending radius of a PGND 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. Cables must be bound tightly and neatly. The sheaths of cables must not be damaged. Cable ties must face the same direction, and those at the same horizontal line must be in a straight line. The excess of indoor cable ties must be cut off. The excess of 5 mm (0.197 in.) of outdoor cable ties should be reserved, and the cut surfaces must be 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 laying out cables, avoid sharp objects, for example sharp edges on the wall. If necessary, use tubes to protect the cables. When laying out cables, keep cables away from heat sources, or use heat insulation materials to insulate the cables from the heat sources. Reserve a proper distance (0.1 m [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. Outdoor Cabling Requirements Protect outdoor cables against potential damage. For example, thread the cables through tubes. Cables to be protected include AC power cables, transmission cables, and cables laid out underground. Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 173 DBS3900 LampSite Installation Guide 9 Installing a pRRU3907 Use cable clips to secure cables outdoors. Arrange cables neatly along the routing direction and use cable 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 (4.92 ft) to 2 m (6.56 ft), and CPRI fiber optic cables and power cables are secured with clips at an interval of 1 m (3.28 ft) to 1.5 m (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. When using clips to secure cables, tighten the screws on the clips after all cables are arranged and laid out. Special Cabling Requirements Cabling of PGND cables PGND cables for a base station must be connected to the same ground bar. 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 which they are connected to. 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. 9.4.2 pRRU3907 Cable List This section describes pRRU3907 cables, connectors added to the pRRU3907 cables, and installation positions for both ends of each cable.

Context This section applies to Huawei sign plate labels. If other engineering labels in accordance with local standards are used on site, follow the local standards for attaching sign plate labels. In the DBS3900 LampSite solution, blank L-Shaped engineering labels are delivered by default. The L-shaped label is usually used for the signal cable, E1/T1 cable, optical cable, and power cable. The description in this section takes the Ethernet cable in a base station as an example. Procedure Step 1 Obtain the engineering label to be attached from the whole set of the L-shaped engineering labels, as shown in Figure 14-8. Figure 14-8 Engineering label to be attached Step 2 Attach the long end of the engineering label to the cable in the position 20 mm away from the connector, and then turn over the long end along the adhesive face. Ensure that the edges of the turned-over engineering label are in a line, as shown in Figure 14-9. NOTE By default, the label is attached in the position 20 mm away from the connector. If required, you can change the position to make installation faster and more efficient. Consistency and neatness, however, must be maintained. Step 3 Adhere the long end to the labeling area. Ensure that the spacing between the cable and the labeling area is 2 mm to 3 mm.

Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 237 DBS3900 LampSite Installation Guide 14 Appendix Context This section applies to Huawei sign plate labels. If other engineering labels in accordance with local standards are used on site, follow the local standards for attaching sign plate labels. A sign plate label is usually used for a power cable, ground label, signal cable, and antenna. This section uses 14.3 DBS3900 LampSite Engineering Label as an example. Procedure Step 1 Lead the cable ties through the holes of a label, and then bind the label to the cable, as shown in Figure 14-12. Ensure that the cable ties are led through the holes of the label in the same direction. Figure 14-12 Binding the label (1): Cable tie (2): Label (3): Cable NOTE You should use an outdoor cable tie with a appropriate width in outdoor scenarios (the default is black cable tie with 3.6 mm or 0.14 in. width). The position for banding the label is recommended from 20 mm to 100 mm (0.79 in. to 3.94 in.) away from the cable connector. Ensure the front of the label facing you and not be covered. In case of both ports of the cable connected have different silkscreen, both ends of the cable should bind the port label on the two ends of cable. For example, in dual BTSs cascading scenarios, one end of the cascading FE/GE cable is connected to LAN1 port on BTS0, and the other end connected to WAN port on BTS1. At this point, both ends of the cable should band two labels Micro BTS0 LAN1 and Micro BTS1 WAN. As shown in Figure 14-13, the distance between the two labels is recommended from 10 mm to 20 mm (0.39 in. to 0.79 in.). Figure 14-13 Positions for banding labels Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 238 DBS3900 LampSite Installation Guide 14 Appendix NOTE You may change the positions for attaching labels in actual situations. For example, you can bind a label where the cable is bent. Step 2 Tighten the cable tie, securing the label on the cable, and then cut off the extra part of the cable tie, as shown in Figure 14-14. Figure 14-14 Securing the label on the cable (1): Cable tie (2): Cable (3): Label NOTE l When you bind a label, ensure that the side with characters faces outwards. l Ensure that the labels are attached in an orderly and neat manner. When you cut a cable tie, keep a surplus length of 5 mm to 10 mm (0.20 in. to 0.39 in.). ----End Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 239 DBS3900 LampSite Installation Guide Index Index Issue 07 (2015-12-30) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 240 pico Remote Radio Unit Compliance and Safety Manual Regulatory Compliance Information 1.
