Physical description3-6 iRM4451 RRH Product Description and Installation GuideGPS cables are provided and pre-installed by the Operator. The GPS cable bend radius is ≤0.75 in (19 mm).3.2.2 RF connectorsThere are four 50-Ω, 7/16 RF jacks (M29x1.5 threaded couplings) that terminate on the bottom of the iRM4451. They are marked ANT 1 through ANT 4.The RF cables are supplied and pre-installed by the Operator.The RF 7/16 connectors are secured by torquing the M29 screw ferrule 15–20 in-lb (20–28 Nm) using a torque wrench. NOTEThe Operator is responsible for determining the antenna type, and supplying and pre-installing the antennas at the site.3.2.3 Power connector–48V dc power to the iRM4451 is through a 3-pin circular twist-lock power connector, Tyco TE CPC Series 5 (788189-1). The connector is keyed to prevent mis-mating. The mating plug (TE CPC Series 5 [7963075-1]) is fastened by turning the coupling nut clockwise until it 'clicks' into the locked position. The power connector pin assignments, as viewed from the bottom of the iRM4451, are shown in Figure 3-7.1 –48V dc2 RTN3 NCFigure 3-7 –48 V dc 3-pin circular power connectorWe recommend cable type SOOW, 8 AWG (min.), 2-conductor, stranded copper wires, indoor/outdoor, round cable, rated at 600 V, or equivalent.3.2.4 RET connectorThe RET (Remote Electrical Tilt) connector provides the capability of electrical antenna control to all antennas connected to the iRM4451. Pin assignments for the RET 8-pin DIN connector is shown in Figure 3-8. The connector is keyed to prevent mis-mating. The connector is fastened by turning the coupling nut clockwise until hand tight.
Physical descriptioniRM4451 RRH Product Description and Installation Guide 3-7The RET cable can be daisy-chained to each of the PCS/AWS antenna inputs/outputs served by the iRM4451. Antenna remote electrical tilt control is facilitated within the EMS user interface.Figure 3-8 RET 8-pin DIN connector3.2.5 Fronthaul connectorsTwo Gigabit Ethernet (GigE) optical SFP ports provide connection for up to two duplex multi-/single-mode optical GigE cables. The GigE entry ports, labeled FH1 and FH2, are located on the bottom of the iRM4451 (see Figure 3-5). The Q-XCO quick-lock SFP connectors are RoHs compliant and meet the IEC 61753-1 Cat. E standard for performance. Connector FH1 is intended for fronthaul support. FH2 is used to daisy-chain sidehaul support to up to one other iRM4451.The iRM4451 is shipped with captive dust covers over both of the fronthaul entry ports. The dust covers should remain in place until the GigE optical Ethernet cables are connected. The dust covers are keyed and have red alignment arrows to ensure proper installation. To remove the dust cover, twist 120° and pull. The dust covers are re-installed in the opposite manner.The GigE 2× LC Huber + Suhner Q-XCO fiber optic cable is a specialty cable with a bulkhead cable gland integrated into the cable (see Figure 3-9). The cable gland has a ruggedized quick-lock SFP mating connector and is connected the same way as the dust cap.

Installing the iRM4451iRM4451 RRH Product Description and Installation Guide 6-16 Installing the iRM4451 This section provides the procedure for installing the iRM4451 RRH in remote locations such as on towers, poles, masts, walls, roofs, or other structures utilizing a universal mounting assembly.Instructions for making connections to external interfaces, cabling, grounding and power are also provided.6.1 Assembling cablesThe operator will need to order, pre-assemble, and pre-install various cables to the iRM4451.6.1.1 Verify Operator-supplied –48 V dc power cableThe Operator supplies and pre-assembles the –48 V dc power connection cable. We recommend using a 8 AWG minimum, round, 2-wire with ground, shielded cable rated at 600 V minimum. The female plug (Tyco TE CPC Series PN 78818801), for assembly of the dc power cable, is also ordered by the Operator. The connection configuration for the supply side of the power cable is determined by site specific requirements.6.1.2 Verify Operator-supplied GigE optical cableThe GigE optical fronthaul cable is a custom cable sourced from Huber + Suhner. The Operator is responsible for ordering this cable in the appropriate length according to site requirements. The GigE 2× LC Huber + Suhner Q-XCO fiber optic cable (PN 09H02FG0-50-XA/88-2-L-NN; where NN=length in meters) is a fiber-to-the-antenna (FTTA), Q-XC0 feeder to LC duplex, 5.5 mm in diameter.A cable gland is integrated as part of the GigE optical fronthaul cable and seals the SFP optical connectors inside the bulkhead of the iRM4451 to conform to an IP65 standard, completing the weatherproof seal.The cable gland screws directly into the fronthaul port on the bottom of the iRM4451. A gasket seals the cable gland at the fronthaul port. The sealing nut is then hand-tightened to complete the weatherproof seal.6.1.3 Verify Operator-supplied grounding cableThe grounding cable and ground bonding hardware is supplied by the Operator. The operator pre-assembles the grounding cable prior to routing to the iRM4451 . However, the grounding terminal lug is supplied with the iRM4451 . NOTEThe grounding cable to the iRM4451 should be 3.9 in (10 cm) longer than other cables to the unit. This will maintain ground connection should the cables be pulled off when the unit is extended beyond the length of the cables.
Installing the iRM44516-2 iRM4451 RRH Product Description and Installation GuideTo install ground terminal lug:1. Cut a 6 AWG (4.11 mm) stranded grounding cable the appropriate length for the iRM4451 installation.2. Strip away insulation from one end to expose 3/4 in (19 mm) of bare wire.3. Crimp the dual-lug grounding terminal (supplied) to the cable using the special-purpose crimp tool specified in Required tools on page 4-1 (or equivalent) as directed by tool manufacturer instruction manual. Figure 6-12 shows an assembled cable/lug assembly.Figure 6-12 Grounding terminal lug assembled on grounding cable6.2 Routing pre-assembled power/GigE optical fronthaul/grounding cablesThis procedures provides instructions for routing the pre-assembled –48 V dc power cable, the GigE optical fronthaul cable, and the grounding cable to the iRM4451 mounting location before assembling components.To route cables:1. Route the cables from the iRM4451 installation location to cable sources as shown in Figure 6-13.

Installing the iRM44516-6 iRM4451 RRH Product Description and Installation GuideNOTEThe mounting clamp is not used when mounting the iRM4451 to a wall or other flat surface. In addition, the M12 bolts supplied in the hardware kit are not used for wall-mount applications.NOTEThe Operator must provide four (4) M12 anchors, designed for outdoor use, that are compatible with the type structure on which the iRM4451 is to be installed.To install mounting plate on a wall:1. Determine the location where the mounting bracket is to be installed.NOTEThe center-to-center distance for drilling holes to install the selected anchor is 5.5 in (140 mm).2. Using a tape measure and spirit level, mark where the anchor will be installed using a center punch.3. Drill the holes where the fastener will be installed on the wall using a drill bit sized for the fastener.4. Install the iRM4451 mounting bracket to the wall using the four (4) M12 anchor bolts selected and supplied by the Operator, four (4) washers and four (4) lock washers supplied with the mounting hardware.5. Tighten the bolts as specified by the M12 anchor's manufacturer using a torque wrench.6.4 Hoisting the iRM4451 on elevated structuresHoist line eye bolts are located on both sides and the top of the . The hoist line lift points for the iRM4451 is shown in Figure 6-16. An Operator-supplied 2-leg nylon lift sling is attached to the eye bolts and the iRM4451 is lifted directly from the packing container to the mounting location. These are the ONLY recommended points of attachment when hoisting the iRM4451 into position on elevated structures. A tag line can be attached to either eye bolt to control sway during the lift.
