MM-009290-001  13 3.2 GENERAL INFORMATION M/A-COM’s OpenSky® 700 MHz Cell Site base station is a stand-alone fully-digital trunked base station for 700 MHz OpenSky trunked radio networks. Housed in a compact and easy-to-install weather-resistant cabinet, it can be pole mounted, tower mounted or wall mounted. The Cell Site base station requires a co-located continuous-duty 24-volt DC power source, a 700 MHz antenna system, and site-to-site backhaul communication equipment to link it to the high-power SkyMASTR base station/tower site. OpenSky employs Time-Division Multiple-Access (TDMA) digital modulation technology. TDMA allows multiple users to share a single RF channel. Each channel can support simultaneous digital voice and data communications, in either a 2-slot or 4-slot format. The Cell Site base station operates in the OpenSky Trunking Protocol (OTP) mode on a single 25 kHz wide 700 MHz RF channel. A key advantage of OTP mode is its internet protocol (IP) based communication capability. The station has a RF transmit output power range that is configurable between 15 and 37 watts (35 to 45.7 dBm), with a 25-watt continuous-duty rating. The Cell Site base station complements the wide area coverage of a high-power SkyMASTR base station/tower site by providing a cost-effective RF coverage solution for problem areas. It provides consistent RF coverage to low-traffic areas that require only a single (2-slot or 4-slot TDMA) channel for voice and data communications. Cell Site base stations are typically employed in areas that are problem coverage areas for the respective high-power tower site(s). In other words, those areas hard-to-reach from an RF standpoint via the high-power tower site(s) due to difficult terrain or other geographic or man-made RF obstructions. In essence, a Cell Site base station is an extension of a high-power tower site’s network of OpenSky base stations. A Cell Site base station can typically be deployed for one-tenth the cost of a tower site with an equipment shelter.   OpenSky system software up to release 4 utilizes 2-slot TDMA technology. OpenSky system software release 5 and later utilizes 4-slot TDMA technology.

MM-009290-001 14         Figure 3-2:  Cell Site Base Station — Bottom View (Cabling Not Shown) Each Cell Site base station in an OpenSky trunked radio network is assigned to a SkyMASTR base station/tower site within the trunked radio network. The Cell Site base station gains network connectivity via a site-to-site backhaul communication link between itself and the main station/tower site. This is accomplished using IP-based protocols over either a T1/Fractional T1 (FT1) frame-relay landline link, or a 56 kbps Digital Data Service (DDS) landline modem link. T1/FT1 frame-relay and DDS modem landline links are implemented via a router installed inside the base station cabinet. For a T1/FT1 site-to-site communication link, the router is equipped with a T1/FT1 frame-relay option. For a DDS site-to-site communication link, the router is equipped with a DDS modem option. In an OpenSky trunked radio network, each SkyMASTR base station/tower site is assigned a block of Class C internet protocol (IP) addresses. From these addresses, one address is used for the site-to-site backhaul communication link. Site-specific configuration parameters such as site ID, channel ID and site IP address, MDIS IP address, VNIC IP address, etc. are typically loaded into the Cell Site’s Base Station Controller (BSC) before the equipment ships from the factory. The BSC is a part of the station’s Digital Controller/Transceiver (DCX) which is located inside the Cell Site base station cabinet.

MM-009290-001 20   5. SITE PREPARATION 5.1  BEFORE BEGINNING THE INSTALLATION Before beginning an installation, collect information from the Site Deployment Order (SDO) specific to the site access such as: • Permission to access the site. • Important contact names and telephone numbers. • Location of and directions to the site. • Keys and/or lock combinations to access the site and equipment shelter (if any), or points of contact to obtain them. • Site entry alarm system pass-codes and/or disable keys. • Information about work practices needed to work safely at the site. Other important information that may or may not be included on the SDO includes: • Type of mounting—metal pole, wooden pole, tower base, exterior wall, etc. • Drawing or description of each site showing how the equipment is to be installed. • Applicable inspections completed (pole installation, electrical, local build code, etc.)  CAUTION Keep the working environment clean! Control dust, dirt, and shavings for safety, and to protect the equipment. Be sure to follow installation procedures carefully!  5.2 POLE-MOUNT INSTALLATIONS Contact a local utility company and arrange for installation of the required pole type. Refer to the Site Deployment Order (SDO) and other applicable site installation information as necessary. Typically, a 60- or 70-foot tall 12-inch diameter pole is employed, with at least 10 feet of the pole buried in the ground. 5.3 ELECTRICAL POWER 5.3.1 AC Power A Cell Site base station site equipped with a SkyCharger battery backup system requires 100-amp AC electrical service: • Contact the local electrical utility company and arrange for installation of 100-amp electrical service at the site (to the pole/pad/wall/etc.)  Either over-head or under-ground service may be used; however, under-ground service is recommended for improved safety. If over-head service is used, it can be either 100 or 200-amp rated to the base of the power meter. However, if under-ground service is used, it must be 200-amp rated (minimum) to the base of the power meter.
MM-009290-001  21 • The installed power meter must be rated at 200 amps minimum. For pole-mount installations, the meter is normally installed 90 degrees from the Cell Site base station cabinet, and 90 degrees from the SkyCharger battery backup system cabinet. When facing the pole with the Cell Site cabinet on the left and the SkyCharger cabinet on the right, the power meter is located on the far side of the pole. Power meter egress conduit type, size and related wiring should meet all local building codes. • An AC circuit breaker box must be installed. Typically, a 6-breaker load center box is used. For pole-mount installations, the breaker box is normally installed on the pole 180 degrees from the power meter. In other words, when facing the pole with the Cell Site cabinet on the left and the SkyCharger cabinet on the right, the circuit breaker box is located on the near side of the pole. All breaker box egress conduit and related wiring should meet all local building codes. Typically, ¾-inch GRS-type conduit is employed. • A 20-amp Ground Fault Interrupt (GFI) duplex AC receptacle box should be installed just under or beside the AC circuit breaker box. This receptacle is for auxiliary use by installation and service personnel. It should be connected to an independent breaker located in the AC circuit breaker box. This breaker should remain in the OFF position when installation/service personnel are not using it. Box installation, conduit and wiring servicing this box should meet all local building codes. Typically, ¾-inch GRS-type conduit is employed.   All AC circuit breakers for site equipment must remain OFF during equipment installation. The circuit breaker for the auxiliary duplex AC receptacle (if any) can remain on as needed by installation and service personnel. AC power installation methods must conform to all applicable local installation regulations and/or local building codes, including but not limited to the utilization of the proper AC receptacle and circuit breaker combination. If the SkyCharger battery backup system is not used, refer to the sections 5.3.3 and 5.3.4 for additional information. 5.3.2 Generator Power Some systems require emergency generators with automatic switchover systems. The generators must be connected to the external site grounding system and should be located in an outdoor location. There should only be one neutral/ground bond at the site per NEC code. Automatic switchover systems must be disabled during installation. 5.3.3 DC Power The Cell Site base station requires a 27-volt (nominal) DC power source. This source must have a continuous-duty current rating of at least 10 amps, with a ripple of less than 200 mV peak-to-peak at 7 amps, or 250 mV peak-to-peak at 10 amps.  Refer to the specifications section on page 9 for additional information. Typically, the SkyCharger battery backup system is employed to supply DC power to the Cell Site base station, both during normal operating periods and on a temporary backup basis when the site loses AC power. Battery hold-up time may be specified in the equipment contract and/or on the SDO. Refer to the SkyCharger installation manual (MM20963) included with this manual set.
MM-009290-001 22    Like AC power installations methods, a DC power installation methods must conform to all applicable local installation regulations and/or local building codes.  5.3.4  If the SkyCharger Battery Backup Power System is Not Used Some systems require battery backup power connected to the supply system in case of an AC power failure. Preferably, the battery bank should be in a room separate from the radio equipment. If located in the same room as the radio equipment, the battery bank should be at a point furthest from the equipment room entrance/door. In either case, it should have a separate fume extraction system or it should be located directly below the air extraction system for the site. If the SkyCharger battery backup system is not employed, consult the site’s SDO and/or the respective vendor’s DC power supply system installation instructions for additional information or special instructions that may apply. In any case, as previously stated, the DC supply system powering the Cell Site cabinet must have a 10-amp (minimum) continuous-duty current rating. Battery hold-up time may be specified in the equipment contract and/or on the SDO.   NEVER locate batteries near the air intake(s) of an air conditioning or air circulation system!   Always minimize the risk of contact between lead-acid batteries and aluminum alloys!  5.4  GROUNDING THE EQUIPMENT Ensure all equipment and facilities meet the requirements for grounding and lightning protection. Site Grounding and Lightning Protection Guidelines manual AE/LZT 123 4618/1 provides proper grounding procedures. These guidelines must be observed in order to protect the equipment and service personnel from lightning and other sources of electrical surges. See section 7.1 in this manual for additional information. Proper grounding also ensures the MPE radius of the radio frequency (RF) antenna is maintained. The MPE radius is the minimum distance from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than the allowable MPE level set by the FCC.  Refer to section 1 which begins on page 5 for additional information. 5.5 ANTENNA SYSTEM This section is an overview of the antenna system installation. It includes general antenna installation guidelines and installation information for the respective antenna RF coaxial cables.
MM-009290-001  23 Antenna systems are generally installed by crews specially-trained and equipped for working on antenna towers and/or pole-type installations. As a result, this manual assumes skilled personnel of this type will be working on the towers/poles, and installing the antennas and antenna cables. However, it may be necessary for the system installer to provide information and directions to the crew, and to verify proper installation. 5.5.1 Antenna Mounting 5.5.1.1 Simplex Antennas If the installation utilizes simplex antennas (i.e., separate transmit and receive antennas), the Cell Site base station must be equipped with M/A-COM option MACS-NDU1W.  With simplex antennas, antenna installation/mounting locations must provide least 25 dB of isolation between the TX and RX antennas. This is necessary to avoid interference in the receiver caused by the transmitter. An isolation of greater than 25 dB is easily obtained by mounting the transmit antenna at least ten (10) feet above the receive antenna. 5.5.1.2 Duplex Antenna If the installation utilizes a duplex antenna system (i.e., one antenna for both transmit and receive), the Cell Site base station must be equipped with M/A-COM option MACS-NDU1X.  In installations of this type, the respective antenna is normally mounted at the top of the pole. 5.5.2  RF Coaxial Cables When installing antenna RF coaxial cables, refer to the applicable antenna assembly drawing(s) shown in Antenna Systems manual LBI-38983, which is included with this set of manuals. 5.5.2.1 Cable Length The length of the main coaxial cable for each antenna should be a continuous run with no connectors or splices. Smaller diameter, more flexible coaxial cable is typically used at cabinet end of the main coaxial cable to facilitate cable connection and disconnection, formation of drip loops, etc. 5.5.2.2  Cable Minimum-Bend Radius Always adhere to the cable manufacturer’s minimum-bend radius specification. For Andrew cable, the values are listed in the following table. For another cable brand, consult the respective manufacture’s recommendations.
MM-009290-001 24   Table 5-1:  Minimum-Bend Radius for Andrew HELIAX® 50-Ohm Foam Dielectric Coax Cable CABLE SIZE  TYPE  ANDREW PART NUMBER  MINIMUM-BEND RADIUS 1/4-inch  Super-flexible  FSJ1-50A  1 inch (25 mm) 3/8-inch  Super-flexible  FSJ2-50  1 inch (25 mm) 1/2-inch  Super-flexible  FSJ4-50B  1.25 inches (32 mm) 1/2-inch  Hard-line  LDF4-50A  5.0 inches (125 mm) 7/8-inch  Hard-line  LDF5-50A  10 inches (250 mm) 1-1/4-inch  Hard-line  LDF6-50  15 inches (380 mm) 1-5/8-inch  Hard-line  LDF7-50A  20 inches (510 mm) 5.5.2.3 Hoisting Grips Hoisting grips provide the means to attach a lifting mechanism to the coaxial cable without damaging it. Typically, each hoisting grip is capable of safely lifting 200 feet of cable without causing cable damage. Therefore, one hoisting grip is required for every 200-foot cable section. Grips may be left attached to the cable after the cable installation is completed. Some situations may require more hoisting grips, such as: • An installation on a tower which is on top of another structure; or, • Any installation where the lengths of cable that must be lifted is greater than the height of the tower/pole. In these situations, additional hoisting grips should be ordered and used as needed.  CAUTION Never attach lifting ropes or hoisting grips to an RF connector on the end of a coax cable. 5.5.2.4  Hangers and Adapters Coaxial cables on the tower/pole should be secured at 3-foot intervals (maximum distance). Securing 7/8-inch and 1-5/8-inch diameter coaxial cables is accomplished by using either hangers or hanger-adapter combinations. The hangers secure the cables to the tower/pole structure by using pre-punched holes or attachment adapters. • For wooden poles, shelf-thread lag bolts should be used. • When a tower structure is pre-punched with 3/4-inch holes, snap-in hangers should be used. • When a tower structure is pre-punched with 3/8-inch holes, each hanger should be secured with a 3/8-inch bolt. • For towers without pre-punched holes, hangers and adapters are available for either angle tower members or round tower members.
MM-009290-001  25 Adapters for each antenna system are selected when ordering the system. If antenna coaxial cable must be attached to a structure that is not compatible with any of the previously described hangers or adapters, additional materials or other special considerations may be required. To secure 1/4-inch or 1/2-inch vertical or horizontal coaxial cables of any size, the use of heavy-duty nylon cable ties is recommended. 5.5.2.5 Weatherproofing Connectors A kit of weatherproof tape is normally provided to protect coaxial connectors from the outside elements. Follow all cable manufacturer weatherproofing guidelines. 5.5.2.6  RF Entry Point (Wall Feed-Thrus) If the Cell Site base station cabinet is located inside an equipment room, the room’s RF entry point (wall feed-thrus) should be installed and the respective bulkhead grounded in accordance with the procedures presented in Site Grounding and Lightning Protection Guidelines manual AE/LZT 123 4618/1 (manual include with this manual set). 5.5.2.7  Grounding Transmission Lines and Surge Protection Devices (SPDs) All RF transmission lines and surge protection devices (SPDs) should be grounded in accordance with procedures presented in Site Grounding and Lightning Protection Guidelines manual AE/LZT 123 4618/1.  AE/LZT 123 4618/1 is include with this set of installation manuals. 5.6  SITE-TO-SITE (BACKHAUL) COMMUNICATION LINKS If the Cell Site base station will employ a landline backhaul communications link (i.e., the router with the T1/FT1 frame relay option or the router with the 56 kbps DDS modem option) for the site-to-site backhaul communication link, suitable lines should be in-place before beginning site installation. Typically, lines are ordered from and supplied by the local telephone company. Interfaces will be agreed demarcation points to which the customer/installer will make connections. • For pole-mount installations, the Telco connection box is normally mounted on the same side of the pole as the Cell Site cabinet. Some installations use a NEMA (Type 12, 13, 4) box such as Hammond Manufacturing’s EJ12126. • For other type installations, the Telco connection box can be mounted at any nearby approved mounting surface such as the exterior wall of an equipment building. 5.7  UNPACKING THE BASE STATION EQUIPMENT Cell Site base station equipment is generally packed in mini-pallets approximately 36 inches deep by 32 inches wide. These pallets can generally be moved with a medium-duty hand-truck. A crowbar and hammer will be useful for opening the crates. Wrenches will be needed to unbolt the cabinets from the pallets. Carefully examine each carton upon receipt. If any packaging damage is detected, note the damage on the Bill of Lading.
MM-009290-001 26   Before unpacking a pallet or crate, move it as close as possible to the installation location. Carefully unpack the equipment and examine each item for damage. If any, contact the carrier immediately and have their representative verify the damage. Failure to report shipping damage immediately may cause forfeiture of any claim against the carrier. When unpacking the equipment, check the contents against the packing list. Contact your M/A-COM representative and the carrier if any discrepancies are noted. After unpacking, carefully open each cabinet and inspect its contents to ensure the enclosed equipment has not been damaged during delivery. If damage has occurred, note details of the damage and, if necessary, contact the carrier immediately and have their representative verify the damage. Contact your M/A-COM representative if the damage is such that installation cannot proceed.
MM-009290-001  27 6. MECHANICAL INSTALLATION This section includes mechanical installation procedures for the 700 MHz Cell Site base station and the related equipment. Because of the wide variety of installation conditions and configurations, many installations will require unique mechanical installation planning processes which must be accomplished on a site-by-site basis. For example, installers typically encounter several different types of mechanical installation scenarios such as wooden pole or metal pole mounting, optional cabinets that must be installed on the same pole as the Cell Site base station, if the battery cabinet is installed on the same side of the pole or the opposite side of the pole, etc. The Site Deployment Order (SDO) should include an accurate site layout map, information to designate equipment locations, and other necessary installation information.   Unless otherwise stated, all installation procedures presented in this section should be performed in the order presented. 6.1  MOUNTING THE CELL SITE BASE STATION Mounting the Cell Site base station typically involves attaching its mounting brackets to the mounting surface (i.e., wooden pole, metal pole, tower base), attaching the base station’s Heat Sink Assembly to the mounting brackets, lifting the base station cabinet and bolting it to the Heat Sink Assembly, and attaching the cabinet’s solar shield. However, if the base station is mounted to a flat surface, no bracket is required since the Heat Sink Assembly is simply bolted directly to the mounting surface. Cell Site base station installations typically employ 60 or 70-foot-tall 12-inch-diameter wooden or metal poles, with at least 10 feet of the pole buried into the ground. Two pole-mount installation kits are available—one for wooden poles and one for metal poles. Each kit contains two (2) mounting brackets and hardware for attaching the brackets to the pole. See Table 6-1 and Table 6-2 for kit contents. 6.1.1  Attaching the Mounting Brackets to a Wooden Pole The following procedure is recommended for wooden pole installations. It is assumed the pole is already planted, and that it is vertically level to within 2 degrees: 1. Consult the SDO for the required height above ground specification, and any other mounting-related instructions/requirements. Most installations require the bottom of the base station cabinet at a distance of at least eight (8) feet from the surface of the ground. 2. On the base station cabinet-side of the pole, mark a drill-point location for the lower mounting bracket’s bolt hole. The bottom of the cabinet will be at approximately this same level above ground. However, the bottom edge of the Heat Sink Assembly will be approximately 3.5 inches lower than this point after it is attached to the brackets. See Figure 6-1. 3. Using a bubble or a laser-type level for an accurate vertical reference line, mark a drill-point location for the upper mounting bracket’s bolt hole exactly 16-¾ inches above the mark for the lower bracket’s bolt hole. This mark must be directly above the mark for the lower bracket’s bolt hole. As
MM-009290-001 28   illustrated in Figure 6-1, the two end holes in one of the brackets may be used as a measuring tool, as these holes are exactly 16-¾ inches apart. 4. Using a centering-type gauge/tool, a level-equipped drill, and a 7/8-inch (0.875-inch) drill bit, drill two 7/8-inch holes at the marked locations. These holes must pass through the pole’s diameter-line (within approximately 5 degrees) and they must be perpendicular to the length of the pole (also within approximately 5 degrees). 5. Attach the two (2) mounting brackets to the pole using the ¾-inch hardware included in Pole-Mount Installation Kit MACS-NMA6D (for wooden poles).  See Figure 6-1 and refer to Table 6-1 for kit contents. Do not torque this hardware until after the Heat Sink Assembly has been attached to the brackets (as described in a later section). 6. Advance to section 6.1.3, Attaching the Heat Sink Assembly to the Mounting Brackets (on page 30).

It is assumed the pole is already planted and it is vertically level to within 2 degrees: 1. Consult the SDO for the required height above ground specification, and any other mounting-related instructions/requirements. Most installations require the bottom of the base station cabinet at a distance of at least eight (8) feet from the surface of the ground. 2. On the base station cabinet-side of the pole, mark a location for the lower mounting bracket’s bolt hole. The bottom of the cabinet will be at approximately this same level above ground. However, the bottom edge of the Heat Sink Assembly will be approximately 3.5 inches lower than this point after it is attached to the brackets. 3. Using a bubble or a laser-type level for an accurate vertical reference line, mark a location for the upper mounting bracket exactly 16-¾ inches above the mark for the lower bracket. As illustrated in Figure 6-1, the two end holes in one of the brackets may be used as a measuring tool, as these holes are exactly 16-¾ inches apart. 4. Using the two (2) stainless-steel straps included in Pole-Mount Installation Kit MACS-NMA6E (for metal poles), attach the two brackets to the pole. Refer to Table 6-2 for kit contents. Tighten the straps in accordance with the installations instructions included with the straps. 5. Add the anti-sway straps to the brackets in accordance with the included installation instructions. 6. Advance to section 6.1.3, Attaching the Heat Sink Assembly to the Mounting Brackets (on page 30).

Figure 6-2:  Attaching the Heat Sink Assembly to the Mounting Brackets (Top View; Wooden Pole Installation Shown) 6.1.4  Attaching the Heat Sink Assembly to a Flat Surface Instead of pole or tower base mounting, the Cell Site base station may be mounted directly to a flat surface such as the interior or exterior wall of an equipment shelter. This is accomplished by attaching its Heat Sink Assembly directly to the flat surface. Six (6) 3/8-inch bolts are used to secure the Heat Sink Assembly to the surface (not supplied). The following procedure is recommended: 1. Consult the SDO for the required height above ground specification, and any other mounting-related instructions/requirements. Most installations require the bottom of the base station cabinet at a distance of at least eight (8) feet from the surface of the ground.

MM-009290-001  33 2. Obtain 3/8-inch hardware appropriate for the mounting surface. For example, if mounting to a concrete wall, expandable concrete anchors with appropriate 3/8-inch bolts and washers are normally used. Use of stainless-steel bolts and washers is recommended. For a flat surface that is less than approximately ¾-inch thick, the 3/8-inch stainless-steel hardware in Pole-Mount Installation Kit MACS-NMA6D (includes 1-3/8-inch long stainless-steel bolts) may be used if the opposite side of the mounting surface is accessible. In this case, the two brackets in the kit are not be used and they can be returned to stock or discarded.  CAUTION A steel mounting surface must be grounded by ground wires/cables that are separate from the wires/cables used to ground the base station cabinet.   Verify the mounting surface has no embedded electrical wires, water pipes, etc., or other items on the opposite side such as fuel tanks, batteries, or equipment cabinets. If so, adjust the location of the mounting surface as required so any drilled holes and/or mounting bolts do not interfere with or penetrate items of this type. 3. Using a bubble or a laser-type level for an accurate vertical reference line, mark a vertical centerline for the Heat Sink Assembly. 4. From this centerline, mark two (2) parallel lines exactly 8-3/8 inches (8.375 inches) from the centerline. One line exactly 8-3/8 inches to the left of the centerline and one line exactly 8-3/8 inches to the right of the centerline. 5. On the two (2) parallel lines, mark drill-points for the two bottom bolt holes. The bottom edge of the Heat Sink Assembly will be approximately 3.5 inches lower than these points after it is attached to the mounting surface. However, the bottom of the base station cabinet will be at approximately the same level (height above ground) as these two bolt holes. 6. On the two parallel lines, mark drill-points for the two center bolt holes exactly 8-3/8 inches (8.375 inches) above the bottom holes. 7. On the two parallel lines, mark drill-points for the two top bolt holes exactly 8-3/8 inches (8.375 inches) above the center holes. 8. To verify the locations of the marked drill-points, position the Heat Sink Assembly over the points. Adjust marks if they are incorrect. 9. Center-punch these six (6) drill-points and then drill pilot holes at the six drill-point locations. An 1/8-inch pilot hole is recommended. 10. Re-drill the six pilot holes to the required diameter according to utilized mounting hardware. Hole diameter is typically 3/8-inch, unless anchor or toggle-type hardware is used which will typically require larger holes. 11. Position the Heat Sink Assembly over the bolt holes and install the mounting hardware as required. A flat washer must be used between the head of the each bolt and each mounting hole in the Heat Sink
MM-009290-001 34   Assembly, and between each mounting hole in the Heat Sink Assembly and the mounting surface. If the mounting surface is not nearly completely flat, additional flat washers should be used as required to prevent bending of the Heat Sink Assembly when the bolts are torqued. 12. Torque the six (6) bolts as required per utilized hardware. Torque the two (2) center bolts (left and right sides) first, then torque the four (4) corner bolts. Do not exceed (TBD) pound/inches. Exceeding this torque spec could cause the Heat Sink Assembly to immediately crack, or crack later during temperature cycles. 6.1.5  Attaching the Cabinet to the Heat Sink Assembly After the Heat Sink Assembly is attached to its mounting surface, the Cell Site base station cabinet must be attached to it per the following procedure: 1. Using a lint-free cloth dipped in denatured alcohol, clean the machined heat transfer surface at the back of the base station cabinet and the corresponding surface on the Heat Sink Assembly. The machined surface at the back of the cabinet is the portion of the station’s RF High-Power Amplifier (HPA) heat sink and casting that is visible on the outside of the cabinet. This surface transfers heat to the Heat Sink Assembly via a special thermal interface material applied later. 2. After cleaning, allow several minutes for the alcohol to evaporate.   Observe and follow all recommended safety procedures, warnings, etc. listed by the alcohol’s manufacturer and/or respective Material Safety Data Sheet (MSDS). 3. At the back of the base station cabinet, apply Thermal Interface Material HT-008474 (included with installation kit) to the HPA’s machined heat transfer surface. This material has an adhesive side to adhere to the machined surface, and a foil side which contacts the Heat Sink Assembly when the two are joined together in the next step. Visually center the material parallel to the machined surface, then lay it flat against the surface and use a gentle top-to-bottom sweeping motion to smoothly adhere the material to the surface. 4. Using the cabinet’s lifting handle, carefully lift the cabinet and hang it on the Heat Sink Assembly by the two (2) hooks at the top rear corners of the cabinet. 5. Slightly reposition the cabinet left or right as necessary to align the six (6) holes in the its rear panel to the six corresponding threaded holes in the Heat Sink Assembly. 6. Start 3/8-inch mounting hardware in all six locations. Use a lock washer and a flat washer on each bolt, with the lock washer adjacent to bolt head and the flat washer adjacent to rear panel hole. Do not tighten any one bolt until all hardware has been started. 7. Torque all of the 3/8-inch mounting bolts to (TBD) pound-inches. 6.1.6  Install the Solar Shield Over the Cabinet If not already, Solar Shield FM-008077 must be installed over the base station cabinet by attaching it to the Heat Sink Assembly. This shield improves heat dissipation characteristics of the cabinet during
MM-009290-001  35 daylight hours compared to an unshielded cabinet, and it helps to reduce build-up of foreign material on the top of the cabinet. The Solar Shield is a part of Heat Sink & Solar Shield Pole Mount Kit option MACS-NCK1G.  Attach the shield to the cabinet in accordance with this procedure: 1. Position the Solar Shield directly above the Cell Site base station cabinet’s lifting handle so the shield’s vent slots (on the top of the shield) are up/sky-facing, and its back with the tracked edges are directly above the two vertical grooves in top-front edge of the Heat Sink Assembly. 2. Slide the Solar Shield’s tracked edges down through the respective vertical grooves in the Heat Sink Assembly until the shield is all the down on the assembly. 6.2  MOUNTING THE SKYCHARGER CABINET Mounting the SkyCharger cabinet includes attaching mounting brackets to the mounting surface (i.e., wooden pole, metal pole, flat surface), lifting the cabinet and attaching it to the brackets. For complete installation details, refer to the SkyCharger installation manual (MM20963) included with this manual set.
MM-009290-001 36   7. ELECTRICAL INSTALLATION 7.1  PROTECTIVE GROUND CONNECTIONS All Cell Site base station related equipment must be grounded in accordance with the instructions presented in the Site Grounding and Lightning Protection Guidelines Manual AE/LZT 123 4618/1 (included with this installation manual set). This includes all metal (electrically conductive) items mounted to or in the near vicinity of the pole/mounting surface. Pole-mount installations must employ at least two ¾-inch diameter 8- to 10-foot long copper-clad ground rods near the base of the pole. These rods are driven into the ground to at or below grade-level, and the top of one rod is considered the site’s common ground point. Bentonite can be used to improve the rod grounding performance. Refer to the Site Grounding and Lightning Protection Guidelines Manual for additional information. To ground the site’s antenna(s), a single conductor of 2 AWG solid copper wire (minimum) or of 28 strands of 14 AWG copper wire (minimum) must be run up the pole to the base of the antenna(s). This conductor must be installed inside PVC type conduit secured to the opposite side of the pole from other conductors as much as possible to minimize the risk of flashover during a lightning strike. Make connections to the antenna(s) in accordance with the instructions provided by the antenna’s manufacturer. Primary ground conductors must be exothermically welded (e.g., using Cadweld® process or equivalent) at the top of each ground rod. High-compression type connectors should not be used at the ground rods. Ground the Cell Site base station, SkyCharger battery charger system, and other equipment using separate ground conductors to the common ground point. These conductors must also be installed inside PVC type conduit that is secured to the pole. Refer to the Site Grounding and Lightning Protection Guidelines Manual for additional information. The Cell Site base station cabinet has a stainless-steel 3/8-inch ground stud located at the bottom of the cabinet, near the bottom of the Customer Interface Box.  Secure a ground conductor to this ¾-inch-long stud using a 3/8-inch 16-threads-per-inch (UNC) stainless-steel nut, a stainless-steel 3/8-inch flat washer and a 3/8-inch lock washer. For grounding instructions on the SkyCharger battery backup system, refer to the SkyCharger installation manual (MM20963) included with this manual set. 7.2 POWER CONNECTIONS  CAUTION To prevent damage to equipment, ensure power is not accidentally applied at this time. Make sure all equipment circuit breakers are OFF.  DO NOT apply power at this time! Temporarily label all applicable circuit breakers accordingly to avoid accidental turn-on! Refer to the SkyCharger’s installation manual (MM20963) included with this manual set for general instructions on making AC and DC power connections. DC power connections to the Cell Site base station are accomplished at the +24-volt terminal block in the Customer Interface Box. The DC power wires from the SkyCharger’s cabinet to the Cell Site cabinet must be routed inside conduit.
MM-009290-001  37 7.3  ANTENNA CABLE CONNECTIONS Antenna cable connections are made at the N-type RF connectors located on the bottom of the Cell Site base station cabinet. For simplex antennas, two cable connections are required. For duplex antenna, only one cable connection is required. 7.3.1 Simplex Antennas If the site employs simplex antennas (separate transmit and receive antennas), follow this procedure to make RF antenna cable connections to the base station. It is assumed both antennas and associated antenna feedlines (i.e., coaxial cables) are already secured to the pole/tower, and they have been tested for proper performance: 1. Determine which cable is the receive antenna cable and which cable is the transmit antenna cable. Mark each cable accordingly. If the site has a Tower-Top Amplifier (TTA), the receive antenna cable connects to it. 2. Verify the antenna system is properly grounded. 3. Cut each cable to the required length, leaving length for a 180-degree 8- to-10-inch diameter drip-loop at the bottom of the cabinet. For best results when cutting the cable, use an Andrew EASIAX® coaxial cable cutting tool (or equivalent). This tool will cut the cable properly for easy connector attachment. 4. Install N-type male RF connectors onto each coaxial cable. 5. At the bottom of the cabinet, connect the receive antenna cable to the receive antenna port and connect the transmit antenna cable to the transmit antenna port. Refer to Figure 3-2. 6. Using soft-jaw pliers, tighten both RF connectors securely. 7. Tie and stow the cables as necessary to prevent cable movement in strong winds. 7.3.2 Duplex Antenna If the site employs a duplex antenna, follow this procedure to make the RF antenna cable connection to the base station. It is assumed the antenna and the associated antenna feedline (i.e., coaxial cable) are already secured to the pole/tower, and both have been tested for proper performance: 1. Verify the antenna system is properly grounded. 2. Cut the antenna cable to the required length, leaving length for a 180-degree 8- to-10-inch diameter drip-loop at the bottom of the cabinet. For best results when cutting the cable, use an Andrew EASIAX®  coaxial cable cutting tool (or equivalent). This tool will cut the cable properly for easy connector attachment. 3. Install N-type male RF connectors onto each coaxial cable. 4. Connect the antenna cable to the duplex antenna port at the bottom of the cabinet.
MM-009290-001 38   5. Using soft-jaw pliers, tighten the RF connector securely. 6. Tie and stow the cable as necessary to prevent cable movement in strong winds.
MM-009290-001  39 8. POWER-UP PROCEDURE The following power-up procedure is recommended: 1. In the site’s main AC circuit breaker box, verify the AC circuit breaker for the SkyCharger battery backup system is OFF and verify the respective DC load (output) circuit breaker is OFF. If the SkyCharger system is not employed at the site, verify the corresponding AC circuit breaker for the site’s 24-volt DC power source/battery charger is OFF and verify the respective DC load (output) circuit breaker is OFF. 2. Verify all mechanical and electrical installations are complete. 3. Verify all equipment is properly grounded. 4. Open the access door of the Cell Site base station’s Customer Interface Box and set both the main DC circuit breaker (labeled BREAKER) and the DCX power switch (labeled DCX POWER) to their OFF positions, if not already. 5. If the SkyCharger battery backup system is employed, perform all SkyCharger system AC power-up and DC voltage checks in accordance with the instructions provided in the SkyCharger’s installation manual (publication number MM20963). After completing these checks, leave its AC circuit breaker and the DC load (output) circuit breaker that powers the Cell Site base station cabinet both ON . If the SkyCharger system is not employed, perform site battery charger AC power-up and DC voltage checks in accordance with the instructions provided with the vendor equipment. After completing these checks, leave its AC circuit breaker and the DC load (output) circuit breaker that powers the Cell Site base station cabinet both ON. 6. In the Cell Site base station’s Customer Interface Box, verify the DC supply voltage at the main DC input terminal block is between 24.0 and 28.5 Vdc. (+ with respect to ground).  The nominal DC voltage level is 27.5 Vdc.  Also verify correct polarity! Do not proceed until the DC voltage and polarity are verified!   The TVS protection diodes on the Customer Interface Board’s DC input begin to conduct at approximately 31.1 Vdc (+ with respect to ground). Therefore, exceeding this approximate DC supply power input voltage potential will cause the main DC circuit breaker to trip off if it is on. Reversed polarity connections (at any DC voltage) will also cause the breaker to trip off. 7. In the Customer Interface Box, turn on the main DC circuit breaker (labeled BREAKER) while observing the HPA’s power indicator (labeled POWER ON in the HPA section). The HPA in the cabinet is “hot-wired” (i.e., its power is not switched on and off by the main DC power switch). Therefore, this indicator will light when the HPA is powered-up, even when the DCX power switch is off.
MM-009290-001 40   8. In the Customer Interface Box, turn on the DCX power switch (labeled DCX POWER) while observing the DCX’s power indicator (labeled POWER ON in the DCX section). This indicator will light when the DCX is powered up. 9. In the Customer Interface Box, verify the DC supply voltage at the main DC input terminal block remains 24.0 and 28.5 Vdc. (+ with respect to ground).  The nominal DC voltage level is 27.5 Vdc.  If the DC supply voltage is not with this range, refer the battery backup system’s installation manual for troubleshooting information. 10. Continue with the configuration procedures presented in the next section. Several Light-Emitting Diode (LED) status indicators are located at the front panel of the Customer Interface Box.  Indicator operation is summarized in the following table:
MM-009290-001  41  Table 8-1:  LED Status Indicators at Customer Interface Box’s Front Panel FRONT PANEL DESIGNATION  INDICATOR COLOR  INDICATOR OPERATION DCX Section:     POWER ON  Green  This indicator lights to indicate the DCX is powered-up. The DCX consists of the BSC and BSX assemblies. SELF TEST  Red  This indicator blinks to indicate the DCX’s BSC is in a self test mode. The BSC executes a self test just after it is powered-up or reset. RX DATA  Green  This indicator blinks to indicate the DCX’s BSC is receiving data from the Ethernet or SLIP interface. TX DATA  Green  This indicator blinks to indicate the DCX’s BSC is transmitting data to the Ethernet or SLIP interface. HPA Section:     POWER ON  Green This indicator lights to indicate DC operating power (24 volts nominal) is applied to the Cell Site base station and the station’s HPA is powered-up. Since the HPA is “hot-wired,” it remains powered-up even when the DCX power switch on the front panel is in the OFF position. TX ON  Red  This indicator lights when the HPA is transmitting RF power to the 700 MHz antenna system. RF DISABLED  Amber  This indicator lights to indicate the HPA transceiver has been disabled. This is accomplished by placing the RF ENABLE/DISABLE rocker switch in the RF DISABLE position.
MM-009290-001 42   9. CONFIGURATION 9.1 GENERAL INFORMATION Cell Site base station configuration is performed during final equipment tests at the factory in accordance with the customer’s order. Most configurations are programmed into the BSC section of the Cell Site’s DCX.  These factory configurations include but are not limited to: • Site ID number • Site color • Area color • Channel ID number • Wide Area Network (WAN) IP addresses • RF operating frequencies (transmit and receive) • Service Provider Network Identifier (SPNI) number • Wide Area Service Identifiers (WASI) number • Site adjacency data Optional configurations programmed into the optional equipment include: • Router parameters (if so equipped) The Cell Site base station requires very little configuration in the field. Once the mechanical and electrical installations are completed, the equipment is powered-up, and the site-to-site backhaul communication link is established, configuration must be performed at the network level. Each Cell Site base station in an OpenSky trunked radio network is assigned to a SkyMASTR base station/tower site within the trunked radio network. The Cell Site base station gains network connectivity via a site-to-site backhaul communication link between itself and the main station/tower site. This is accomplished using IP-based protocols over either a T1/Fractional T1 (FT1) frame-relay landline link, or a 56 kbps Digital Data Service (DDS) landline modem link. Therefore, the site-to-site backhaul communication link must be operational before configuration can be performed. 9.2  CELL SITE ALARMS 9.2.1  AC/DC Power Source Alarms The SkyCharger battery backup system is configured at the factory to generate alarms based upon any one of the following conditions: • Loss of AC input power • Door open (or low battery voltage) • Charger rectifier failure
MM-009290-001  43 Alarm logic states are transferred from the SkyCharger cabinet to the Cell Site cabinet via the modular cable that interconnects between terminal block TB3 in the SkyCharger cabinet and the ALARM modular jack at the front panel of the Cell Site cabinet Customer Interface Box. Inside the Cell Site cabinet, these alarm logic states are then passed to the BSC in the DCX for processing. For remote alarm monitoring purposes, after processing by the BSC, the alarm states are transferred over the IP-based network to the radio system’s Network Switching Center (NSC)4 and Centralized Network Manager (CNM)5. 9.2.2 HPA Alarms Cell Site base station HPA-related alarms are preset at the factory and require no configuration. These alarms include: • Loss of “heartbeat” • Loss of Automatic Level Control (ALC) • Low DC input voltage condition • Over current condition (of HPA DC input power) • Over temperature condition Like the power source alarms, these alarms are processed by the BSC and then transferred over the IP-based network to the radio system’s NSC and CNM for remote monitoring purposes. 9.2.3  Cabinet Door Alarm The Cell Site base station’s cabinet door alarm disables the HPA from transmitting when the Customer Interface Box’s door is open, activating the alarm. No field configuration is necessary.                                                  4 The NSC was formerly referred to as the Regional Operation Center (ROC). 5 The CNM was formerly referred to as the Network Operations Center (NOC).
