The RF cables are supplied and pre-installed by the Installer in lengths according to site requirements.The 4.3-10 RF jack screw connector is secured by torquing the coupling nut to 44.25 in-lb (5 Nm) using a torque wrench.NOTEThe Installer is also responsible for determining the antenna type, and supplying and pre-installing the antennas at the site.The recommended RF jumper cable is an IP-68 compliant, Amphenol 4.3-10, male to 7/16 DIN male, with super flex cable (Part No. AAS-12HF-43SMDM-xM). The variable x is the length of the jumper in meters, where x = 1.0, 2.5, or 5.0. The RF jumper cable minimum bend radius is 1.2 in (30 mm).NOTEIt is recommended that all RF cables be PIM-tested on site to ensure acceptable performance.3.2.4 Power connector–48 V DC power to the iRM2249 iRRH is through a 2-pin, EMI shielded, circular twist-lock quick connect bulkhead jack, Rosenberger (99K73E-199N1). The connector is keyed to prevent mis-mating. The input pins are isolated from the chassis. The power connector pin assignments, as viewed from the bottom of the iRM2249, are shown in Figure 3-7 –48 V DC 2-pin Rosenberger bulkhead jack on page 3-8.Figure 3-7 –48 V DC 2-pin Rosenberger bulkhead jack

Physical description iRM2249nn00-1 iRRH Product Description and Installation Guide 3-9The isolated input allows the iRRH to be connected with a 2-wire or 3-wire supply. Altiostar recommends a 2-wire connection with the +ve connection referenced to chassis ground at the power connector. This is indicated in Figure 3-7 –48 V DC 2-pin Rosenberger bulkhead jack on page 3-8. To facilitate the 2-wire connection, the supplied cable connector has the positive cable terminal connected to the connector body. The Rosenberger 99S73B-199N1 cable connector supports the 2-wire connection. If an isolated supply (3-wire connection) is required, then an alternative Rosenberger 99S73J-199N1 cable connector is available.The mating plug (Rosenberger 99S73B-199N1) is fastened by turning the coupling nut clockwise 1/4 turn by hand until it 'clicks' into the locked position. To remove the power plug, twist the coupling nut counter-clockwise 1/4 turn.The iRM2249 comes supplied with an unconnectorized Rosenberger plug (99S73B-199N1) in a kit (Figure 3-8 Rosenberger –48 V DC power plug (exploded view) on page 3-9). The Installer assembles the cable onto the plug. Assembly instructions (MA_99A5) are found in the kit with the mating plug.Figure 3-8 Rosenberger –48 V DC power plug (exploded view)The power source end of the plug has screw terminals for connection to Installer-provided 8 AWG power cables. Power cable connection at the source end of the power cable (an Installer supplied and assembled task) is shown in Figure 3-9 Cable connection for supplied 2-pin Rosenberger plug on page 3-10.

To remove the power plug, twistthe coupling nut counter-clockwise 1/4 turn.Instructions for the connector assembly are included in the box. The Installer must assemble the cable on site in a length ordered according to the site requirement. Use the cable HUBER and SUHNER with part number 85013657 or equivalent. The power cable length should be decided based on the position of the iRRH and the DC power supply. Ensure the voltage input at the iRRH power supply connector to be in the range of -40VDC to -58VDC. The maximum length of the power cable should not exceed 100m to minimize the voltage drop across the cable. The Rosenberger connector with part number 99S73B-199 or equivalent is used with the cable. Refer to the Altiostar cable assembly drawing 360-00-0272 for details.For assembly instructions of the power connector and cable, refer to Assembly instructions for 2-pin power connector and cable on page A-1.The following points list the power cable recommendations:• Cable should be a 8 AWG minimum (to minimize any voltage drop in the DC feed), round, 2-wire, shielded (recommended) / unshielded /co-axial cable rated at 600 V minimum, or equivalent. • The connector can support cables in the range AWG8-AWG16. Hence, smaller gauge cables could be used for short feed lengths.• Cable should have Copper or Aluminum wire gauge of approximately 10mm2 with 2 cores.

Physical description iRM2249nn00-1 iRRH Product Description and Installation Guide 3-11• Cable should support current per conductor >40A and resistance between 1.83 ohm/Km to 3.08 ohm/Km.• Cable temperature range: -40degC to +90degC.• Cable Standard: IEC 60228 class 2.• Outer cable diameter should be in the range of 7mm to 17mm.• Cable wires carry -48VDC and RTN.The following points list the power connector recommendations:• Rosenberger type power connector (99S73B-199) is always used and comes pre-fitted to the iRRH from manufacturing.• EMI shielded connector with a metallic body.• 2 pins, -48VDC and RTN.• The connector is designed so that the braided shield engages with the metallic connector assembly to provide continuous shielding.• RTN terminal connected to the housing.• Use common single point grounding.3.2.5 RET connectorThe RET (Remote Electrical Tilt) bulkhead connector provides the capability of electrical antenna control to all antennas connected to the iRM2249. Pin assignments for the RET standard 8-pin DIN connector is shown in Figure 3-10 RET standard 8-pin DIN connector on page 3-11. The connector is keyed to prevent mis-mating.

Physical description3-12 iRM2249nn00-1 iRRH Product Description and Installation GuideThe RET cable and connectors is a standardized AISG RET Control Cable available from many vendors. Installer supplies and installs RET cables in lengths according to site requirements.The RET cable can be daisy-chained to other antennas served by the iRM42249 iRRH if the option is provided by the RET motor manufacturer. Antenna RET control is facilitated within the EMS user interface.The Installer is responsible for providing and pre-assembly of the standardized RET cable and connector in a length according to site requirements.3.2.6 Fronthaul connectorsTwo Gigabit Ethernet (GigE) optical SFP fronthaul ports provide connection for up to two duplex multi-/single-mode optical GigE cables. The GigE ports, labeled FH1 and FH2, are located on the bottom of the iRM2249 iRRH (see Figure 3-4 iRM2249 iRRH GPS and fronthaul connectors location on page 3-5). Connector FH1 is intended for fronthaul support. FH2 is used to daisy-chain sidehaul support to up to one other iRM2249.NOTEAltiostar recommends the use of MM SFP module from Finisar – PN: FTLF8519P3BTL or SM SFP module from Finisar – PN: FTLF1318P3BTL for the FH1 and FH2 GigE ports.The macro iRRH is shipped with Rosenberger Fiber Enclosure (RFE) flange (PN 98Z405-K00)—a bulkhead connector with captive dust cover—installed. The mate to the flange is the RFE ‘plug’ (Rosenberger PN 98Z105-S00) which contain the two duplex optical GigE fiber cables and protects the fiber connections. One (1) RFE plug is provided with the macro iRRH. They are UL94-V0 and IP67 compliant at–40° to 158° F (–40° to 70° C).To assemble the Rosenberger RFE plug, the threaded sealing nut is first routed onto the fiber cable, followed by installation of a split grommet and clamping claw onto the fiber itself (see Figure 3-11 Rosenberger RFE fiber-optic enclosure on page 3-13 for the order of RFE assembly). The fiber cable/split grommet/clamping claw assembly is then pressed and seated into the plug body. Approximately 3–5 in (76–127 mm) of fiber cable, including the duplex fiber plug, should extend beyond the outside after the RFE ‘plug’ assembly is assembled.The RFE plug is assembled by screwing the threaded sealing nut clockwise until it seats into position, hand tight, on the plug body. This completes the assembly of the RFE plug. The fiber connector is then inserted into the SFP fiber module, which is recessed in the iRRH fronthaul port, until it ‘clicks’ into position. Any slack fiber cable is stored inside the RFE plug. The RFE alignment rails on the RFE plug are engaged now with the bulkhead connector. When pushed in firmly, it ‘clicks’ into place and is locked onto the bulkhead connector

Physical description iRM2249nn00-1 iRRH Product Description and Installation Guide 3-13completing the installation. The RFE cannot be removed because the latch function has been disabled by the obstruction at the latch pivot when seating the threaded sealing nut.To remove the RFE plug from the bulkhead connector, the plug housing must be turned counter-clockwise until obstruction of the release latches on either side of the plug body, has been cleared. Finally, pressing on both latches at the same time and pulling the plug body removes the RFE from the bulkhead connector.For assembly instructions of the Rosenberger Fiber Enclosure, refer to Assembly instructions for Rosenberger Fiber Enclosure on page A-4.Figure 3-11 Rosenberger RFE fiber-optic enclosureThe dust covers over the FH1 and FH2 flanges should remain in place until the GigE optical Ethernet cables are connected and on any unused port. The dust covers are keyed to ensure proper installation. To remove the dust cover, just pull it off. The dust covers are re-installed in the opposite manner.The recommended GigE fiber optic cable (x2) is OM1 62.5/125, military fibercable, with dual LC/dual LC termination, 10.0 m in length and is provided byL-Com (part no. FODLCMIL-10, or equivalent).NOTE Remove the dust cap only when ready to connect the cable to the iRM2249.The GigE optical fronthaul cables are supplied and pre-installed at the site by the Installer. Detailed assembly instructions (Rosenberger PN MA_98A1) are supplied with each Rosenberger RFE in its packing box.1 Threaded sealing nut 4 Plug body2 Split grommet 5 LC-LC duplex fiber/connector3 Clamping claw 6 Bulkhead connector
