![2.1 Reference DocumentsBefore the installation, you must be familiar with reference documents.The following reference documents are required during RRU installation:lRRU3203 Hardware DescriptionlDBS3900 Installation GuidelOCB User GuideThis document describes the RRU installation on a pole, U-steel, angle steel, or wall. If RRUsare installed on the IFS06, the following reference document is required:lDBS3900 (ICR) Installation Guide2.2 Tools and InstrumentsAll tools and instruments required for RRU installation must be ready before the installation.Hammer drill (a φ 14 bit) ESD gloves Vacuum cleanerHeat gun Phillips screwdriver (M3 toM6)Flat-head screwdriver (M3 toM6)Rubber mallet COAX crimping tool Wire stripperUtility knife Cable cutter Adjustable wrench (capacity≥ 32 mm [1.26 in.])RRU3203Installation Guide 2 Installation PreparationsIssue 06 (2012-04-16) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.5](https://usermanual.wiki/Huawei-Technologies/RRU3203-B12.UserManual-InstallationManual-pdf/User-Guide-2196892-Page-13.png)

Before performing any operation, onsitepersonnel must be familiar with correct operation methods and safety precautions.Before the installation, pay attention to the following items:lThe customer's technical engineers must be trained by Huawei and be familiar with theproper installation and operation methods.lThe number of onsite personnel depends on the engineering schedule and installationenvironment. Generally, only three to five onsite personnel are necessary.RRU3203Installation Guide 2 Installation PreparationsIssue 06 (2012-04-16) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.6](https://usermanual.wiki/Huawei-Technologies/RRU3203-B12.UserManual-InstallationManual-pdf/User-Guide-2196892-Page-14.png)
![2. Hit the expansion bolt with a rubber mallet until the expansion tube completely enters thehole.3. Tighten an expansion bolt slightly and place it vertically into each hole.4. Remove the M10x65 bolt, spring washer, plastic tube, and flat washer from each expansionbolt assembly in sequence.NOTEAfter completely removing an expansion bolt, store the plastic tube properly.5. Hammer the bolt into the wall.CAUTIONDo not hammer the expansion bolt entirely into the wall. Instead, leave 20 mm (0.79 in.)to 30 mm (1.18 in.) of the expansion bolt outside the wall.Step 3 Fit the auxiliary mounting bracket on the expansion bolt, and then use a torque wrench (17 mm[0.67 in.]) to tighten the expansion bolt to 30 N·m (265.52 lbf·in.), as shown in Figure 7-36.Figure 7-36 Fitting the auxiliary mounting bracket on expansion bolts CAUTIONVerify that the arrow on the auxiliary mounting bracket is pointing up.Step 4 Loosen the screws on the main mounting bracket and store them properly.Step 5 Install the main mounting bracket, as shown in Figure 7-37.RRU3203Installation Guide 7 Installing the RRUIssue 06 (2012-04-16) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.58](https://usermanual.wiki/Huawei-Technologies/RRU3203-B12.UserManual-InstallationManual-pdf/User-Guide-2196892-Page-66.png)
![8.1 Cabling RequirementsCables must be routed according to the specified cabling requirements to prevent signalinterference.NOTEIf a cable listed below is not required, skip the routing requirements of the cable.General Cabling RequirementsRequirements for Bending RadiuslThe bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bendingradius of the 5/4'' feeder must be more than 380 mm (14.96 in.).lThe bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bendingradius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bendingradius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.).lThe bending radius of the power cable or PGND cable must be at least three times thediameter of the cable.lThe bending radius of a fiber optic cable is at least 20 times the diameter of the fiber opticcable, and the minimum bending radius of the breakout cable at each end of the fiber opticcable is 30 mm (1.18 in.).lThe bending radius of the E1/T1 cable must be at least three times the diameter of the cable.lThe bending radius of the signal cable must be at least five times the diameter of the cable.Requirements for Cable BindinglThe same types of cable must be bound together.lDifferent types of cable must be separately routed with the minimum spacing of 30 mm(1.18 in.) and cannot be entangled.lThe cables must be bound tightly and neatly. The sheaths of the cables must not be damaged.lCable ties are installed in the same direction, and those at the same horizontal line must bein a straight line.lThe excess of indoor cable ties is trimmed off, and the excess of outdoor cable ties allowsabout 5 mm (0.2 in.), without remaining rough edges.lLabels or nameplates must be attached to both ends, joints, or turns of cables after they areinstalled.Security RequirementslCables should be placed away from sharp objects or wall burrs. If these positions areinevitable, protect the cables with protection pipes.lCables must be routed away from heat sources, or heat-insulation materials are addedbetween cables and heat sources.lSufficient slack (recommended for about 0.1 m [0.33 ft.]) is provided in cables at turns orthe position close to a device, facilitating cable and device maintenance.Indoor Cabling RequirementslCables are routed indoors through the feeder window.RRU3203Installation Guide 8 Installing RRU CablesIssue 06 (2012-04-16) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.62](https://usermanual.wiki/Huawei-Technologies/RRU3203-B12.UserManual-InstallationManual-pdf/User-Guide-2196892-Page-70.png)
