If the rain-proof gasket is damaged, replace the system (RRH-B8) with a new one. © SAMSUNG Electronics Co., Ltd. VII Ver. 1.0 SAFETY CONCERNS Radius of Curvature of Feeder Line When installing a feeder line, the radius of curvature of the sections where cables bent should be larger than the allowed radius of curvature. If the radius of curvature for the feeder line installation is less than the allowed radius of curvature, it may affect the performance of the system. Connection of Feeder Cable Connector Connecting the feeder cable connector is critical process, so the qualified workers who finished the related education should perform. Caution When Connecting RET Cable Make sure to turn off the breaker connected to the RRH-B8 power of the DU cabinet before connecting the RET cable between the antenna RET port and the RRH-B8 RET port. If you connect or disconnect the RET cable while the breaker is turned on, it may cause an electric short circuit resulting in damage to the RET function. Installation General Managing unused port Finish unused port of UADU by dust-cap, not making the alien substance flowed. Finishing Cable Insertion Hole Finishing work is required on cable insertion holes (Cable gland, Conduit and etc.) to prevent entering of any foreign substance, external air and moisture. - Unused cable insertion hole: Finish cable insertion hole using fishing materials such as dust cap, rubber packing and etc. - Cable-installed insertion hole: After installing cable, finish insertion hole using tape, compressed sponge, rubber packing, silicon, etc. to prevent empty space. VIII © SAMSUNG Electronics Co., Ltd. 2600-00CTEIGAA Ver. 4.0 Smart MBS RRH-B8 Installation Manual/Ver.1.0 Caution when assembling the cable gland Ensure that all parts of the cable gland are assembled in the correct sequence. Incorrect assembly may result in influx of external air or moisture into the system and may cause corrosion, system malfunction and/or critical failure of the cooling system. Caution when installing the cable in the cable gland Only one cable of permitted specification (radius) should be installed in the cable gland. - Installing a cable of smaller radius than the permitted specification may result in influx of external air or moisture into the system and may cause corrosion or system malfunction. - Installing a cable thicker than the permitted specification or installing two or more cables in the gland may damage the gland. Caution when loosen and tighten the Cable Gland Nut In case of assembling the cable gland and cabling, do not loosen and tighten by turning the cable gland body or other parts. turning the cable gland body may cause corrosion and system failure by entering of any external air and moisture. Checking assembly state of the unused cable gland All components of the unused cable gland must be secured in the original factory configuration. If the cable gland nut is fitted without the rain protection filler or the protection cover in place, reassemble them as illustrated in ‘Figure 2.7.’ Do not work by yourself Do not work by yourself in any key process. Caution for cleaning the Rack Make sure that worker does not damage installed cables while cleaning the rack. Cautions When Connecting the CRPI Cable Failure to observe the CPRI cable connection specified in Table 2.5 may impair the communication between the CDMA and LTE FDD terminal. © SAMSUNG Electronics Co., Ltd.

(Cable tray, ducts, flexible pipe, etc.) Cable Cutting Measure the exact distance, carefully checking the route, and cut the cable using a cutting tool. Follow these guidelines when cutting the cable. Cut the cable to the length determined in the Cable Path Inspection step. Use a dedicated cable cutting tool. Cut the cable at right angles. Be careful to keep the cable away from any moisture, iron, lead, dust or other foreign material when cutting. Remove any foreign material attached to the cable using solvent and a brush. Cable Installation Cable installation involves running the cable along the cabling path to the target connector of the system or an auxiliary device after cable path inspection and cable cutting have been completed. Follow these guidelines when installing a cable. 1-8 Be careful not to damage the cable. If the cable is damaged, cut out the damaged section before installing. Run the cable so that it is not tangled. In particular, when installing a cable from a horizontal section to a vertical section, be careful not to reverse the upper and lower lines of the cable. Always use the maximum curvature radius possible, and make sure that the minimum curvature radius specification is complied with. If the cable needs to be protected, use a PVC channel, spiral sleeve, flexible pipe, and cable rack, etc. © SAMSUNG Electronics Co., Ltd. 2600-00CTEIGAA Ver. 4.0 Smart MBS RRH-B8 Installation Manual/Ver.1.0 Table 1.2 Minimum Allowed Cable Bend Radius No Type Min.

Cable Binding Cable binding involves fixing and arranging an installed cable using binding strings, cable ties, binding lines, and ram clamps, etc. Follow these guidelines when binding a cable. Be careful not to damage the cable during binding. Use appropriate cable binding tools according to the target location (indoor or outdoor, etc.) and the use of the cable (power supply cable, optical cable, feeder line, etc.). Do not let the cutting section of a cable tie and binding line, etc. be exposed to the outside. This may cause damage to cables or personal injury. Make sure that the cutting sections of cables are not exposed to the outside. Trim the binding string so that you have about 1.97 in. (5 cm) of string left from the knot. And insert the remaining string into the knot and make sure the knot does not loosen. If there is a potential danger of contact failure in a connector connection due to tension, install the cable in the shortest distance. © SAMSUNG Electronics Co., Ltd. 1-9 Ver. 4.0 2600-00CTEIGAA CHAPTER 1. Before Installation Connector Attachment Connector attachment involves assembling a connector to an installed cable or to a device on the site. Follow these guidelines when attaching a connector. Make sure you are fully aware of the connector assembly method before assembling a connector. Assemble the connector in accordance with its pin map. Each connector has a hook to prevent its core positions from being changed. Use a heat shrink tube at a connector connection for cables that are installed outdoor, such as feeder lines, to prevent water leakage and corrosion from occurring at the part exposed to the outside. Connect each cable of the connector assembly in a straight line. Be careful when connecting a cable not to trigger contact failure at a connector connection due to tension. Identification Tag Attachment Identification tag attachment involves attaching a marker cable tie, nameplate, and label, etc. to the both ends of a cable (connections to a connector) to identify its use and cabling path. Marker Cable Tie On the marker cable tie, a label can be attached. The appearance and specification may differ depending on the type and manufacturer. Follow these guidelines when attaching an identification tag. When installing a cable outdoor, use relief engraving and coated labels, etc. to prevent markings from being erased. Since the form and attachment method for identification tags are different for each provider, consult with the provider before attaching them. Connecting Ground Cable In cabling, the connection of cables without the connection to the ground cable may cause the damage of the equipment or the bodily injury of the worker. Connect the ground cable first. Cable Installation Checklist When installing, take care not to overlap or tangle the cables; also, consider future expansion.

Sector Antenna Installation A.1 Cautions when Installing a Sector Antenna Precautions of antenna installation are as follows. Sector antennas should be installed vertically. (±1°) Antenna is the precise material, so be careful not to make damage or form change. When moving antenna, use the tool suitable to rating. In addition, use the rated carrying device which is at least 200 % or more than antenna considering the stability. Be careful not to give too much strength to the antenna. If it rains, suspend connecting the feeder cable and antenna. Fix it after adjusting the direction of antenna exactly. Distance between steel tower and antenna and the distance between send-receive antennas are based on the antenna layout. Attach the antenna on the position specified in the drawing. Install the antenna not to make a feature change of the antenna considering the direction of the radiation When connect the connector to the antenna, not making the alien substance flowed and is not under the influence of PIMD. Measure VSWR of all antennas and the value should be within the regulated value. A.2 Sector Antenna Layout The method of sector antenna layout is as follows. 1) 2) 3) 4) Use the transit to adjust the antenna installation direction exactly. Fix the direction of the sector antenna, same as the angle settled when designing the cell after installing the steel tower. Arrange the antennas of each sector to the sector directional angle at right angles by adjusting the distance between antenna and steel tower. In the event of the station whose the direction between sectors is not 120°, install it to make the steel tower and antenna direction different being careful of the tilt and azimuth. For circular platform, separate the antenna interval at maximum. © SAMSUNG Electronics Co., Ltd. A-1 Ver. 4.0 2600-00CTEIGAA ANNEX A. Sector Antenna Installation A.3 Sector Antenna Installation The method of sector antenna installation is as follows. 1) Put up an antenna pole and insert the sector antenna into the antenna pole using a fixing clamp. 2) Set the antenna’s up/down tilt to 0° and fix the fixing clamps at the top and bottom. 3) After tightening the fixing clamp, adjust the antenna up/down (tilt) depending on the signal strength. The bolt of the guide clamp must be loosened, so the antenna angle can be adjusted. 4) After setting the antenna angle, fasten the bolt of the guide clamp, which was loosened previously. Regarding the nut, the double nut mounting should be used to prevent the nut from coming loose.
