Direct contact or indirect contact via damp objects and conductors with high-voltage wires or mains supply may be fatal.
Installation Manual Airbridge cBTS3612 CDMA Base Station PrecautionsSafety Precautions　S-5 l Installation of AC power supply equipment must be implemented in compliance with local safety regulations, and the personnel engaged in AC power supply must be qualified for high-voltage and AC operations. l Electrical conductors such as watches, bracelets and rings must be removed before operation. l If the cabinet is found to be wet, please turn off power supply immediately. l Keep the equipment dry upon operation under humid environment. Warning: Improper high-voltage operations may result in fire accidents and electric shocks. Therefore, AC power cables must be laid in compliance with local codes and regulations. High-voltage operators should be trained and qualified. 3.2 Power Cables Caution: Live installation and removal of power cables are prohibited. Electric sparks or arcs may be generated when power cables get in touch with conductors, which may cause fire accidents or eye injuries. l Power must be switched off before installation and removal of the power cable. l Before connecting a cable, make sure that the cable and cable label to be used should match actual installation requirements. 3.3 Tools Warning: High-voltage and AC operations require special tools instead of general-purpose or makeshift tools.
Installation Manual Airbridge cBTS3612 CDMA Base Station PrecautionsSafety Precautions　S-6 3.4 Drilling Warning: Unauthorized drilling on the cabinet is strictly prohibited. Improper drilling may damage the connections and cables inside the cabinet and the metal filings produced during the drilling may cause short-circuits of the circuit boards if they fall into the cabinet. l Wear protective insulation gloves and remove the cables inside the cabinet before drilling holes on the cabinet. l Take care of your eyes when drilling holes. As the splashing metal burrs &scraps may hurt your eyes. l Prevent metal scraps from entering the cabinet inside. l Improper drilling will damage the electromagnetic shielding performance of the cabinet. l Clean up the metal scraps after drilling. 3.5 Thunderstorms Danger: High-voltage and AC operations and operations on the steel towers and masts are strictly prohibited in a stormy weather. l Thunderstorms can generate powerful electromagnetic field in the atmosphere. Therefore, equipment should be grounded properly in order to prevent the equipment from being thunderstruck. 3.6 Static Electricity Caution: Static electricity generated by the human body may damage the electrostatic-sensitive parts on the circuit boards, such as large-scale integrated circuit (IC). l The grating generated between human activities and the components is the rootage for electrostatic charge accumulation. In dry climate, the
Installation Manual Airbridge cBTS3612 CDMA Base Station PrecautionsSafety Precautions　S-7 electrostatic charge carried by human body may go up to 30 kV, which will remain on the human body for a rather long period of time. The operator’s contact with the sensitive component and the resultant electric discharge will cause damage to the component. l Before contacting/touching any equipment such as holding plug-in boards, circuit boards and IC chips, put on the anti-static wrist strap with one end well grounded so as to prevent sensitive parts from getting damaged by static electricity on the human body. l Before operators touch the board or module, they should release the electrostatic charge in their body. That is, before the operator touches a board or a module, he or she must wear the anti-static grounded wrist strap. The connecting line between the wrist and the grounding point should connect in series with a resistance greater than 1 M¦¸ to protect people from being accidentally shocked. The resistance value greater than 1 M, is rather low in terms of electrostatic voltage discharging. The anti-static wrist strap should be checked regularly. Using other cable to replace the cable of anti-static wrist strap is strictly prohibited. l Electrostatic-sensitive board or module should not be in contact with the object with static electricity or the object that may easily generate static electricity. For instance, packaging bags, delivery boxes and conveyor belts made of insulating materials will generate static electricity by themselves, and can cause electrostatic charging when in contact with human body or the earth and might thus bring forth damages. l Electrostatic-sensitive boards or modules can only contact quality discharging materials, such as anti-static packing bags. The board in stock or in the course of transportation should be packaged with anti-static packing bag. l Before the measurement device is connected to boards or modules, first discharge its static electricity, that is, the measurement device should be grounded first. l The single board or module should not be placed near strong DC magnetic field, for instance, near the cathode ray tube of the oscilloscope. The safety distance should be at least 10 cm. l Damage caused by static electricity is accumulative. If the damage is slight, the component will not malfunction. However, as the number of damages increase, the components may suddenly fail. The electrostatic discharging damage to the component is of two types: obvious damage and hidden damage. Hidden damage is not shown when the damage occurs, whereas the component may become vulnerable and easily get damaged under the condition of over-voltage and of high-temperature. The correct way of wearing anti-static wrist strap is shown in Figure 1.
Installation Manual Airbridge cBTS3612 CDMA Base Station PrecautionsSafety Precautions　S-8 Plug of anti-static wrist strap Figure 1 Wearing the anti-static wrist strap 3.7 Power Labels Caution: Before connecting the cables, check the correctness of labels and then make the connection. 3.8 Leakage Current Warning: To avoid the occurrence of large leakage current, the equipment must be grounded before connecting to the power supply. l Before connecting the AC input power supply, the operation and maintenance personnel should first connect the protection-grounding terminal of the equipment housing to the earth. The purpose of doing so is to avoid electric shock on human body resulting from leakage current, which is usually caused by the earth capacitance of the EMI wave filter at the AC power supply input terminal of the equipment or the Y capacitance of the primary power supply.
Installation Manual Airbridge cBTS3612 CDMA Base Station PrecautionsSafety Precautions　S-9 3.9 Flammable Air Environment Danger: The equipment should not be placed in an environment where flammable, explosive air or smog exists.

Pay attention to the direction of the subrack, and mark the positions of four connecting holes of the cabinet (Each cabinet has four connecting holes).
Installation Manual Airbridge cBTS3612 CDMA Base Station Hardware Installation3 Cabinet Installation 3-6　III. Drilling Drill holes on the floor at the marks of the cabinet connecting holes with a percussion drill. The drill bit size should be v14 or v16. Caution: 1. Generally, the selected drill bit is bigger than the expansion bolt. If the hole diameter is too small for the F14 drill bit, enlarge the hole diameter by technical means. 2. Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it in the right direction, as vibrations of the drill may damage the floor or produce a slanting hole. 3. The hole depth should be the length of the expansion bolt stem plus the drill bit. All holes should share the same. Before measuring the hole depth, remove the dust inside the hole with a vacuum cleaner, then drill again if necessary. 4. If the ground is too hard and smooth to settle the drill bit, punch out a pit with a chisel before drilling. 3.2.3 Installing Lower support I. Installing the expansion bolt 1) Before the installation, remove the dust inside and outside the holes with a vacuum cleaner, and then check the hole distance. Whenever big errors occur, the concerned hole must be re-located and re-drilled. 2) Unfix the spring washer, nut and the big plain washer, put the bolt into the hole and strike it with a hammer (such as nail hammer) until the bolt is completely driven into the hole. To avoid the vibration of the bolt in the hole, put the nut on the bolt and screw the nut until the bolt is slightly exploded in the hole. Caution: Take off the spring washer before installation, otherwise the washer will get invalid when the expansion bolt is knocked. Carefully knock the bolt into the hole so as to avoid damaging the bolt thread. II. Installing the lower support 1) Place the insulating plate and the lower support in turn aligning with the four expansion bolts. 2) Put insulating covering, big plain washers, spring washers Ö12 and nuts M12 onto the four expansion bolts in turn; make the nuts cross-fastened one by one;

Support assemblies There are four types of assemblies in A600 series: three height-adjustable types and one height-fixed type. For their range of adjustable heights, please see Table 3-1. Table 3-1 Heights of A600 series supports assemblies Assembly Adapted anti-static floor heights (mm) I 195~230 II 231~300 III 301~445 IV Customized according to the floor height (min height: 140mm) & Note: The anti-static floor height refers to the distance between the upper surface of the anti-static floor and the concrete floor.
Installation Manual Airbridge cBTS3612 CDMA Base Station Hardware Installation3 Cabinet Installation 3-10　The heights of A600 series support assemblies I, II and, III can be adjusted steplessly within their adjustable ranges. The heights are adjusted by moving the upper and lower supports. Type IV assembly is a height-fixed support. It is mainly suitable for ultra-high and ultra-low floors. The minimum applicable floor height of this assembly is 140mm. III. Support installation The support is installed in the floor-bracketing mode. Namely, bracket the floor between the cabinet and the support, then run the bolts through the anti-static floor to fix the cabinet and the support. In this way, the cabinet can be firmly fixed and supported. IV. Number of supports 2N installation supports are used to install the cabinets, i. e., N cabinets should be supported with 2N supports. Figure 3-9 is the schematic diagram of cabinet installation on anti-static floor. Figure 3-9 Cabinet installation on anti-static floor

Marking Place the lower support of the cabinet on the ground as per the cabinet layout (make sure it is in correct direction). Mark the positions for all connecting holes (each cabinet has four connecting holes) of the cabinet on the floor. III. Drilling Remove the lower support and drill a hole through the marked place for each connecting hole on the anti-static floor with a v20 drill bit. 3.3.4 Locating Support I. Positioning and marking for support Place the support below the anti-static floor. Align the connecting holes of the support with the holes on the anti-static floor. Take the installation hole of the support as the template. Mark positions for the expansion bolts on the concrete floor. Caution: The support should be installed strictly based on the blueprint shown in Figure 3-11. The connecting holes at the outer side of the support should be aligned with the floor holes to prevent the support extruding out of the cabinet. (1) Connecting hole (for outer use) (2) Anti-static floor Figure 3-11 The connection between the support connecting holes and the floor holes
Installation Manual Airbridge cBTS3612 CDMA Base Station Hardware Installation3 Cabinet Installation 3-13　II. Drilling Use a Ö14 or Ö16 bit to drill holes at the marked places. Caution: 1. Generally the size of the selected bit is bigger than the expansion bolt. If the hole diameter is too small for the Ö14 drill bit, enlarge the hole diameter by technical means. 2. Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it in the right direction, as vibrations of the drill may damage the floor and enlarge the size of the hole or produce a slanting hole. 3. The hole depth should be the length of the expansion bolt stem plus the length of the drill bit. All bolts should share the same depth. Before measuring the hole depth, remove the dust inside the hole with a vacuum cleaner, and then drill again if necessary. 4. If the floor is too hard and smooth to settle the drill bit, punch a pit with a chisel to help positioning the hole. Marking and drilling are the fundamental steps for the hardware installation. If the result is not accurate, it will bring trouble to the future work. Thus the quality at the initial stage is the prerequisite of the whole project. III. Installing expansion bolts 1) Before fixing the expansion bolts, clean the dust inside and outside the hole with a vacuum cleaner, then measure the distance between holes. For the hole with intolerable error, it should be re-located and drilled again. 2) Unfix the spring washers, nuts and plain washers; put the expansion bolts perpendicularly into the installation holes; carefully knock the bolts with a hammer (nail hammer) into the floor. To avoid the bolts getting loose in the hole, install and tighten the nuts. Pull the expansion bolt until it slightly expands. Caution: Take off the spring washer before installation, otherwise the washer will get invalid when the expansion bolt is knocked. Carefully knock the bolt into the hole so as to avoid damaging the bolt thread. IV. Adjusting support height Adjust the support to the predefined height, finely adjust the height-lock bolts on the upper support to such an extent that they will not slip down by itself. Put the support

Screw the M12×70 bolts from the top to bottom. Meanwhile, place the plain washer, spring washer and insulating covering (for the purpose of increasing the contact area) as is shown in Figure 3-12. 2) Gently knock the support to adjust the height so that the anti-static floor falls on its original place on the framework. Make sure that the upper plane presses against the anti-static floor. Then, screw the tightening bolts on the anti-static floor. 3) Make the expansion bolts cross fastened to 45Nm with a Torque wrench one by one to reduce the stress between the bolts and the support. 4) Tighten the height-lock bolts to 45Nm with a Torque wrench. The bolts in the middle should be tightened first and then those on both sides. Figure 3-12 is the diagram of bolt position. Caution: Fasten the three bolt sets in strict accordance with the above-mentioned procedures. i.e.: anchor bolt for the floordexpansion boltdheight-lock bolt (first in the middle, then on both sides).

When errors exist, adjust the levelness by adding washers beneath the lower support, as shown in Figure 3-13. 3.3.8 Insulation Test Set the multimeter to the megohm range, and measure the resistance between the expansion bolt and the lower support. If the resistance is greater than 5 megohms, the circuit is an open circuit and the installation thus ends. Otherwise, the lower support is not insulated from the ground. In this case, remove all installation parts and check whether the insulating covering is missing or damaged. Repeat the installation procedures of the lower support and perform the insulation test again. 3.3.9 Cabinet Installation Place the upper support (being fixed already at the lower part of the cabinet upon delivery) to the lower support, push in and fix cabinet with bolts to complete the installation.

The recommended material for the support is the 14b-3000 type of GB707-88 hot-rolled U-bar. The length is based on the actual situation (The total length of the U-bar shown in the figure is 3000mm), Drill installation holes for and fixing holes on the U-bar as shown in and Figure 3-18. Remove all burrs and sharp edges; Finally paint the whole support with rustproof coat and top-coat (The color of the coat should be the same with or similar to that of the cabinet). Thus, the fabrication of U-bar support is completed.

Determine the installation position The installation position of the cabinet should be determined based on the predefined benchmark dimensions in project plane design. II. Marking Determine the installation positions of U-bar supports according to the installation position of the cabinet. Mark several points with a tap and draw two straight paralleling benchmark lines with a marker. The spacing between the two straight lines is 630mm. Then determine the first hole position for the support U-bar on the two lines according to the design requirement. Take this hole as the benchmark point to mark the rest installation holes of the support one by one. Then re-measure the lines to confirm the accuracy of each hole. The installation hole positions for U-bar supports are shown in Figure 3-18.

Drilling Use Ö14 or Ö16 drill bit to drill holes at the marked points on the floor. Caution: 1. Generally, the selected drill bit is bigger than the expansion bolt. If the hole diameter is too small for the F14 drill bit, enlarge the hole diameter by technical means. 2. Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it in the right direction, as vibrations of the drill may damage the floor or produce a slanting hole. 3. The hole depth should be the length of the expansion bolt stem plus the drill bit. All holes should share the same. Before measuring the hole depth, remove the dust inside the hole with a vacuum cleaner, then drill again if necessary. 4. If the ground is too hard and smooth to settle the drill bit, punch out a pit with a chisel before drilling. Marking and drilling hole are fundamental to the hardware installation. If the result is not accurate, it will bring trouble for the future work. Thus the quality at the initial stage is the prerequisite for the whole project. 3.4.4 Fixing U-bar Supports I. Installing expansion bolts 1) Before the installation, remove the dust inside and outside the holes with a vacuum cleaner, and then check the distance among holes. Whenever big errors occur, the relevant hole must be located and drilled again. 2) Unfix the spring washer, nut and plain washer. Put the expansion bolt into the hole and knock directly on the bolt with a hammer (such as nail hammer) until
Installation Manual Airbridge cBTS3612 CDMA Base Station Hardware Installation3 Cabinet Installation 3-22　the bolt is completely driven into the floor. Then, put the nut on the bolt and tighten it until the bolt is expanded slightly so as to avoid it getting loose. Caution: Take off the spring washer first before installation, otherwise, it will get invalid when the expansion bolt is knocked. Carefully knock the bolt into the hole and avoid damaging the threads on the bolt. II. Installing U-bar Supports Install and fix the U-bar support as shown in Figure 3-19. Cross-fasten the nuts of the lower support one by one so as to reduce the stress between the bolts and the lower support.

Installation Manual Airbridge cBTS3612 CDMA Base Station Hardware Installation4 Installation of Cabinet Modules and Parts 4-1　4 Installation of Cabinet Modules and Parts 4.1 Installing Boards of Baseband Subrack The baseband subrack is located at the cabinet–uppermost part. The boards inserted in this subrack are common boards. One connector is equipped at the rear of a board and used to connect to the backplane. On the front of the board are two metal handles with spanners used to pull out and plug in the board. The installation procedures of the board are as follows: 1) Align the board with the positions marked with corresponding board names and push in the board gently along the guide rail until explicit resistance can be felt, then lock the front panel. 2) Fasten all screws one by one in position on the panel with a screwdriver, to ensure that it is seamless between the board panel and the baseband subrack. Caution: 1. Before installing the board, first check the cleanness of the cabinet and the subrack. Clean the cabinet and the frame if necessary. 2. Wear antistatic wrist strap (Make sure that the plug of the antistatic wrist strap is inserted in the socket on the sidedoor post of the cabinet) or discarge the static on the body by touching the chassis before touching the board or the module. 3. Insert the boards strictly according to the labels on the individual nameplates. Do not insert the boards wrong. 4. Insert the board vertically into the subrack and the boards are interconnected through the system bus on the backplane. 5. Insert the boards with care so as to prevent the pins from getting bent on the backplane. 4.2 Installing Other Functional Modules Refer to the following procedures for installing the fan box, power supply module, BTRM module, BHPA module, BTRM fan module, RLDU module and the CDU module. 1) Align the fan box, power supply module, BTRM module, BHPA module, BTRM fan module, RLDU module, and the CDU/DFU/DDU module respectively with the “fan subrack”, “power supply subrack”, “RF subrack”, “RLDU/CDU subrack”
Installation Manual Airbridge cBTS3612 CDMA Base Station Hardware Installation4 Installation of Cabinet Modules and Parts 4-2　and so on, then push them in gently along the corresponding guide rails until explicit resistance can be felt. 2) Fasten all screws into position on the panel one by one with a screwdriver to ensure that it is seamless between module panel and the cabinet subrack. Caution: 1) The transmitting and receiving indexes of the BTS will probably descend if the BTRM, CDU, DFU, DDU, RLDU and other RF modules are not inserted correctly and the screws are not fastened. Meanwhile, the CDU frequency is fixed and not adjustable. Its corresponding upper subrack probably has higher carrier frequency, while the lower subrack has relatively lower carrier frequency. Decide the slot position of the specified carrier frequency module according to the actual frequency in pratical configuration, otherwise, it will result in such faults as low transmitting power of the BTS. 2) When DFU and DDU are used, they have no special requirement on frequencies, and are configured from bottom up in the subracks. Installation processes of fan box, BTRM module, BHPA module, and BTRM fan module are shown in Figure 4-1. And the installation processes of other modules are similar.

II. Installing or disassembling rear doors For the installation or disassembly of the rear door, align rear door with positioning pin of the lower enclosure frame at the back of the cabinet, and install or disassemble the six captive screws on the rear door. Thus that is the whole process. III. Installing or disassembling left-front door and right-front door During the installation for right-front door, align the door with the positioning pin at the right-front of the cabinet, pull the pin at the upper part of the right-front door and align it with the pin hole, thus ending the installation. The process for disassembling the right-front door is exactly reversed. The process for installing or disassembling left-front door is similar to that for installing or disassembling right-front door. 4.4 Setting BCIM Switches and Jumpers The DIP switches of the BCIM and jumpers are shown in Figure 4-2.
