Supported system configurations:

ASTRO 25 Repeater Site Trunked IP Simulcast Subsystems Supported trunked frequency bands:

800 MHz 700 MHz 1.1 DBR M12 MultiCarrier Site in an ASTRO Repeater Site The DBR M12 MultiCarrier Site in an ASTRO 25 repeater site is set up in a single trunked site, with one active control channel and a number of voice channels at the site, with a total of 28 channels. If packet data services are supported at the site, you can configure a number of voice channels with packet data channel capability. Voice traffic is routed to and from each channel (virtualized on a DSC 8500 and utilizing a transceiver) to the system for distribution to other sites and is repeated by the channel to support other local subscribers. However, data traffic is routed to the site controller. The site controller routes these packets upstream to the zone core for further processing and routing. 1.2 DBR M12 MultiCarrier Site in a Trunked IP Simulcast Subsystem The RF channel (virtualized on a DSC 8500 and utilizing a transceiver) captures inbound signals through external receive (Rx) antennas from the subscriber/mobile radios and then amplifies, filters, and demodulates the signals into voice packets which are forwarded to a comparator. The comparator processes the received voice packets for a particular call and forwards the best quality voice packets to the zone core, which routes them to the associated base radio at each remote site. At a predetermined time, all RF channels transmit the voice packets simultaneously on the same frequency to complete the communication. You can install a maximum of 30 RF channels per a remote site. 1.3 DBR M12 MultiCarrier Site Components The DBR M12 MultiCarrier Site consists of an open rack or cabinet that contains the following components:

DSC 8500s Transceivers (XCVRs) 21 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description MultiCarrier Power Amplifiers (MCPA) Transmitter (Tx) Radio Frequency Distribution System (RFDS) components (including an integrated Power Monitoring Unit (PMU)) Receiver (Rx) RFDS components Fan modules Optional AC power supply shelf and modules Optional site routers These modules and components (some of which may be shared among the carriers), provide the functionality necessary to support up to 12 transmit or receive carriers per cabinet or rack. Multiple cabinets or racks can be ordered (up to 3) to create a site with up to 28 channels or carriers (Site Repeater) or 30 channels

(Simulcast). Depending on the selected configuration options, the DBR M12 MultiCarrier Site rack or cabinet can have some or all of the modules shown in the following figure:

Each of the DSC 8500s is able to fully support 12 carriers. The DSC 8500s provide the following functionalities:

Site reference, distributed to all components that require frequency or timing through the Ethernet PTP Optionally an integrated Rubidium that provides up to 72 hours of hold over in the event of GNSS loss DSP symbol and IQ data conversions Station, carrier, channel, and site control (hardware and software) 23 Junction Panel (Open Rack Only)(Cabinet has junction panel included in the top lid)Breaker Access2RU3RU5RUBank 1TXPost Filter/PMURXPreselector(Optional)Bank 2TXPost Filter/PMU(Optional)DiversityPreselectorBranch BAirflowRMC Cage (1-2 site RMC, 1-4 Cabinet RMC)N - way Combiner (1 per TX Antenna)PA CardcagePower AmplifiersPA Fan Kits (3), Filter, and Air IntakeN - way Splitter (1 Per TX Antenna)Transceiver Cardcage (qty 1-12)with dual 6 way excilter combinerCable bracketDSC 8500DSC 8500Cable braket(Optional) Redundant Gateway (Juniper SRX 345)Gateway (Juniper SRX 345)(Optional) AC Supply2RU3RU13RU1RU1RU5RU1RU1RU1RU1RU4RUApplicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description Single point of contact for site configuration, service and maintenance in the Provisioning Configuration Agent (PCA) Network management Alarm I/O ports Site switch interface for:

Local service Site router XCVR Frequency reference, timing, modulation, control, monitoring and alarming MCPA Frequency reference, control, monitoring and alarming PMU Monitoring and alarming Auxiliary connections Conventional Base Radios, and other site equipment Tx and Rx Generation The XCVRs provide for the receiver (RF to IQ data) and exciter (IQ data to small signal RF) conversions in the DBR M12 MultiCarrier Site. Each configured channel (Rx/Tx Frequency) is associated with an XCVR at the site. The association between channel and XCVR is determined automatically by the software to optimize the frequency spacing per bank, the distribution of priority channels (control capable channels), and to support the XCVR n+1 redundancy feature. The association is re-evaluated on a change of frequency, addition/removal of hardware at the site, or during the XCVR n+1 failover. Tx Subsystem (Final Tx Amplification and Tx RFDS) The MCPA bank accepts the combined low-level modulated RF signals from the XCVR modules of a given bank and amplifies them for transmission to the site transmit antenna through the N-Way combiner and the Tx post filter. The use of MCPAs eliminates the cavity combiners and the maintenance they require. Additionally, this architecture provides the following features:

Tx-Tx spacing of 50 kHz (minimum) without the use of hybrid combining Remote frequency changes without an RF site visit Fault tolerance the loss of one MCPA results in the loss of at most one Tx carrier Improved site level carrier availability over temperature The following are the additional DBR M12 MultiCarrier Site transmitter sub-system configurations and features in the same cabinet or rack:

Up to 12 Tx carriers on one Tx antenna (same band) Up to 12 Tx carriers on one Tx antenna (diplexed 700 and 800 MHz bands) Up to two sets of six Tx carriers with each set on a separate Tx antenna (same or different bands) An integrated PMU within the Tx post filter for each Tx antenna (measures composite Tx power) For more information about the splitting and combining configurations involved in the transmit path, see DBR M12 MultiCarrier Site RFDS Transmit Path on page 44. Rx RFDS The DBR M12 MultiCarrier Site integrated RFDS provides a receive multicoupler (RMC) system that is optimized for the solutions that contain a tower top amplifier, and the solutions that do not, in both diversity and non-diversity configurations. The Rx RFDS includes the following components and features:

Dual band (700/800 MHz) preselector for each Rx branch Active Site RMC modules with adjustable gain that support:

30 Simulcast channels 28 Site Repeater channels 6 spare channels Power Subsystem (DC and AC power) The DBR M12 MultiCarrier Site employs a highly fault tolerant power system. When powered by a DC power source (built-in DBR M12 MultiCarrier Site configuration) a distributed DC architecture is utilized. This type of DC architecture offers the following features:

Fault tolerance single DC power source failure results in loss of at most one carrier. Reduces the number of FRUs necessary to support the DBR M12 MultiCarrier Site. When the DBR M12 MultiCarrier Site is powered by an AC power source, an optional AC power supply can be ordered and field installed in the reserved space within the DBR M12 MultiCarrier Site rack or cabinet. This solution provides for n+1 redundancy where no carriers are lost in the event of a singular AC/DC power supply module failure. For more information about the DBR M12 MultiCarrier Site power system, see DBR M12 MultiCarrier Site DC Power System on page 40 and DBR M12 MultiCarrier Site AC Power System on page 43. 1.3.1 DSC 8500 Physical Description The DSC 8500 provides the station control and DSP operations of the individual RF channels assigned to a given rack/cabinet. Two DSC 8500 controllers are equipped in each rack/cabinet, but a single DSC 8500 can support all RF channels in the rack/cabinet it resides in. This arrangement aids in preventing a single point of failure. The DSC 8500 also provides the RF Site controller and reference distribution functionality, also ensuring LAN connectivity and switching within the site. It also provides the time reference within the site and can be connected to a GNSS remote receiver, if already at the site. Each DSC 8500 supports 14 digital inputs that can be monitored and configured to send fault management traps to registered fault managers. The 14 digital inputs are the pull to ground type, which can be driven by an open collector device that is capable of sinking 7 mA. 25 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description The DSC 8500 can be supplemented with an optional rubidium oscillator device to ensure an extended holdover in the event of GNSS signal loss.

The functionality of the 2-3 N-Way combiner and the 4-6 N-Way combiner is the same. The only difference between the two combiners is the number of power amplifiers that can be connected to them. Each rack can support up to two 2-3 N-Way combiners or one 4-6 N-Way combiner. WARNING: An RF Phasing cable must be connected to each input of the N-Way combiner at all times, even if there is no associated PA for that connection. Removing a phasing cable when the site is powered on can cause damage to the equipment. Cables for non-populated PAs must be placed in through the locating features in the PA blank panels.

The center 4.3-10 connector on the N-Way combiner connects to the post filter. Each QN connector is connected to the PA associated with the label next to the connector, or connected to a cable with its other end placed behind the blank panel that corresponds to that PA. 1.3.6 N-Way Splitter Physical Description The DBR M12 MultiCarrier Site rack has two types of N-Way splitters, the 2-3 N-Way splitter and the 4-6 N-Way splitter. The N-Way splitters take the combined XCVR output and split it to each Power Amplifier (PA). The functionality of the 2-3 N-Way splitter and the 4-6 N-Way splitter are the same. The only difference between the two splitters is the number of PAs that can be connected to them. Each rack can support up to two 2-3 N-Way splitters or one 4-6 N-Way splitter. On each board the connectors labeled as XCVR Bank A and XCVR Bank B are connected to the XCVR Combiner board in the XCVR card cage. Each connector labeled as MCPA X is connected to the corresponding PA. 36 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 Figure 15: 2-3 N-Way Splitter MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description Annotation Description 1 Coax jumper connection.

A second Tx post filter is used when there are two transmit banks, and two transmit antennas. 38 0 0 0 0 0 0 0 M0 0 0 0 0 0 0 0 0 0 0 0 0 2 3 4 1 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 Figure 20: Tx post filter MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description Annotation Description 1 2 3 4 Tx connection from combiner (4.3-10) Tx to antenna (4.3-10) Power monitor (Ethernet connection) 30dB coupled output (QMA) The transmit filter removes any remaining noise in the receive sub-band between the combiner and the transmit antenna. The transmit band pass filter has a built-in power monitor on the output for monitoring the antenna system voltage standing wave ratio (VSWR) and the composite transmitter output power in reference to the top of the DBR M12 MultiCarrier Site cabinet/rack. The composite transmitter output power and VSWR can be viewed in the Provisioning and Configuration Agent (PCA). Additionally, the VSWR alarms are routed to the infrastructure as they occur. The transmit filter is either 768776 MHz or 851870 MHz. The Tx post filter is band-dependent. There are two versions, one for the 700 MHz and one for the 800 MHz range. A rack can contain both bands if it is set up as a split bank. Tx post filter 1 connects to a 4-6 N-Way combiner, or a 2-3 N-Way combiner for a single or split bank configuration. Tx post filter 2 only connects to a 2-3 N-Way combiner in a split bank configuration. The 30dB coupled output allows you to see the composite filtered output spectrum of the DBR M12 transmitter subsystem. 39 2314Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description Figure 21: Rx Preselector Annotation Description 1 2 3 Rx out to site Receive Multi-Coupler (RMC) (QMA) Tx to antenna (4.3-10) 30dB coupled output (BNC) The Rx preselector covers both the 700 MHz and the 800 MHz range. Only one preselector is required even if there is both a 700 MHz range and 800 MHz range transmit bank in the same rack. The first preselector connects its Rx output to the site RMC 1. If there is Rx diversity, the second preselector connects to the site RMC 2. The 30dB coupled output allows you to monitor the composite filtered input spectrum to the DBR M12 MultiCarrier Site receiver subsystem. 1.3.8 DBR M12 MultiCarrier Site DC Power System The DC power is the default configuration of the DBR M12 MultiCarrier Site, unless the optional AC power supply (T8926A) is ordered. The DBR M12 MultiCarrier Site employs a distributed DC architecture (there is no central DC supply). The DC-DC converters are distributed throughout the DBR M12 MultiCarrier Site that galvanically isolates and regulates the input 48 VDC power source connection (+/- 43.2-60 VDC). The DC-DC converters are located in each of the Multi-Carrier Power Amplifiers (MCPAs), Transceivers (XCVRs), and components of the distributed DC architecture in the DSC 8500. This type of DC architecture offers high availability and reduces the number of FRUs necessary to support the DBR M12 MultiCarrier Site. The following are the selected functionalities of the DC architecture:

40 231Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description Each MCPA has its own breaker. Each fan is powered by one of two MCPAs. Each router has a separate breaker. Each DSC 8500 has a separate breaker. Each XCVR is powered by one of the two DSC 8500s. Each Receive Multi-Coupler (RMC) (site and cabinet) is powered by one of the XCVRs (up to twelve XCVRS can be present). Figure 22: DC Architecture The DBR M12 MultiCarrier Site is galvanically isolated (floating ground) and may be connected to either a positive or negative grounded 48 VDC power source. Wire colors and schemes may differ, depending on the power ground reference or regional codes, but the polarity does not change. Regardless of power system ground reference, positive is positive, and negative is negative, and connection should be completed to that polarity.

The default configuration is for power to be received from a single DC source through the two DC inputs. If power system redundancy from the two separate DC sources is desired, then you must remove the DC jumper bridging the two DC inputs into the rack/cabinet. The noted jumper is located on the underside of the rack/cabinet breaker rail. NOTE: You should only consider removing the DC jumper for rack/cabinets that are configured for two transmitter banks. Removing the DC jumper allows XCVRs 1-6, MCPAs 1, 3, and 5, and the bottom DSC 8500 to receive power from one DC source. The balance of the XCVRs, MCPAs, and DSC 8500 receives power from the other DC source. This perfect split of the MCPA, XCVR, and DSC 8500 resources can not be achieved with a rack/

cabinet configured for a single transmitter bank. Because of that, the DC jumper must remain in place for rack/cabinets configured for a single transmitter bank. The top of the rack/cabinet contains two sets of terminal blocks for the purposes of reducing the current supplied through any one set of DC input cables to a value within the rating of the DC cables maximum size

(1 AWG) and/or minimizing voltage drops. NOTE: The terminal block screws must be tightened within the range of 6Nm and 8Nm. For racks/cabinets loaded with modules to support the maximum carrier capacity, both pairs of DC feeds must be installed to the power distribution subsection. WARNING: Disconnect all Power before servicing. Multiple power sources may be present. Failure to do so may cause property damage, personal injury or death. AVERTISSEMENT: Dbranchez toute alimentation avant lentretien. Plusieurs sources dalimentation peuvent tre prsentes. Ne pas le faire peut entraner des dommages matriels, des blessures ou la mort.

For more information about the connections, see DBR M12 MultiCarrier Site DC Power System on page 40 and Connecting Power to an AC Power Source on page 81. This option provides two power shelves that can support up to three 1300W AC/DC power supply modules each. 43 123Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 1: DBR M12 MultiCarrier Site Description Figure 25: DBR M12 MultiCarrier Site Power Shelves The DBR M12 MultiCarrier Site AC Power Supply is a separate component that is shipped separately. The integration must be done in the field or in staging at the reserved, open space, at the bottom of the rack. The DBR M12 MultiCarrier Site AC Power Supply supports n+1 redundancy so that no carriers are lost in the event of a singular AC/DC power supply module failure. To ensure that the correct number of AC/DC power supply modules are present to support the n+1 redundancy, see Multicarrier Site Design Tool and DBR M12 MultiCarrier Site Ordering Guide. IMPORTANT: Ensure that an alarm is generated in the event of an AC/DC power supply module failure. The alarm outputs of the DBR M12 MultiCarrier Site AC Power Supply must be wired to the alarm inputs of the DSC 8500 (and configured in the PCA), MC-EDGE RTU or SDM 3000 RTU. A second AC/DC power supply module failure can power down an entire DBR M12 MultiCarrier Site rack or cabinet. 1.4 DBR M12 MultiCarrier Site RFDS Transmit Path The DBR M12 transmitter does not use cavity combiners or lossy hybrid combiners to achieve power combining. The power combining is accomplished before the high power amplification and followed by bank(s) of highly linear MultiCarrier Power Amplifiers (MCPAs) that amplify the already combined carriers.

That is, racks/cabinets loaded with modules to support 12 carriers transmitting at full rated output power, the receive diversity option, the site router option, and the DSC 8500 rubidium option. The top of the rack/cabinet contains two sets of terminal blocks to accept the DC feed line sets. Both of these feed line sets are required to reduce the current supplied through any one set of DC input cables to a value within the rating of the DC cables maximum size (1 AWG) or reasonably limiting the voltage drop of the two feed line sets. The breaker recommendations for two 1 or 2 AWG feed line sets that feed the two terminal blocks are as follows:

Site installation must include a current interrupting device (fuse or circuit breaker) on each of the two feed line sets supplying the two terminal blocks. The current interrupting device for each of the two feed line sets should be 85A. For more information about the sizing of cables and the DC power distribution in installations utilizing rack/cabinet configurations with lesser current draw, see the Standards and Guidelines for Communication Sites manual. 2.2 Cabling Requirements Diagrams for cabling are typically included in the system-specific configuration documentation Motorola Solutions provides. Also see the Motorola Solutions Standards and Guidelines for Communication Sites manual for cabling standards. IMPORTANT: System certification was completed using shielded cables. To prevent emission problems, use only shielded cables. Do not substitute other cable types. Position the equipment to avoid excessive tension on cables and connectors. Cables must be loose with absolutely no stress on the connectors. Careful cable routing and securing the cables with tie wraps (or other devices) is one way to provide this protection. Set up preventive maintenance loops. Dress the cables neatly using cable ties. Do not tighten the cable ties until you are sure that the required service length and bend radius requirements are met. Leave cable ties loose enough to allow adjustment. Verify that all cables are properly labeled to match system-specific configuration documentation Motorola Solutions provided. 54 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 2: DBR M12 MultiCarrier Site Equipment Installation Ensure that cables do not exceed the minimum bend radius as outlined in the Motorola Solutions manual for cabling standards. CAUTION: Use only Category 5e Shielded Twisted Pair (or higher) for cabling Ethernet connections. Motorola Solutions has engineered this system to meet specific performance requirements. Using other cabling and connectors may result in unpredictable system performance or catastrophic failure. ATTENTION: Utilisez uniquement une paire torsade blinde de catgorie 5e (ou suprieure) pour le cblage des connexions Ethernet. Motorola Solutions a conu ce systme pour rpondre des exigences de rendement particulires. Utiliser dautres cblages et connecteurs peut entraner une performance imprvisible du systme ou une panne catastrophique. For more information on cabling guidelines, see the documentation supplied with components from each equipment manufacturer. 2.2.1 DBR M12 MultiCarrier Site Grounding In the DBR M12 MultiCarrier Site, each module, or each card cage that contains multiple modules, is grounded to the rack grounding bar by the use of 6 AWG ground bond cables. The rack grounding bar must be connected to the master grounding bus bar by 2 gauge, 75C rated wire (capable of 170A single conductor) per NEC table 310.15(B)(17). Ground conductor must be connected with the included Panduit LCC2-14A-Q crimp lugs. Crimp connections must be made in accordance with Panduit instructions and by using only the approved tools and dies. The supplementary grounding bus bar must be connected to the master grounding bus bar by 2 gauge, 75C rated wire (capable of 170A single conductor) per NEC table 310.15(B)(17) If a cabinet enclosure is used, you must create a connection from the cabinet top to the #2 wire by using an inline splice, #6 AWG wire, a 5/8 spacing double right angle lug, (Panduit LCC6-14AWF-L or equivalent UL rated crimp lug) and the two studs that use the M5 nuts. If the site grounding system is below the rack instead of above the rack, all #6 AWG ground bonding cables must be rerouted or reversed to connect below each chassis and connection point on the equipment with accordance to R56 guidelines for cable dressing and bend radius requirements. New #6 AWG cables for the RFDS filter elements are required to connect all modules connected to the supplementary ground bus bar to the main grounding bus bar instead. These cables are not provided or available as a standard, and must be procured or fabricated separately.

You can add redundant rubidium frequency references to provide an extended holdover on GPS signal loss. It is recommended that new sites utilize these new capabilities as they save space and power at the site. 2.5 Connecting GNSS Units to DSC 8500s The GNSS units must be mounted with an unrestricted aerial down view to within ten degrees of the horizon in all directions. The GNSS units must be mounted high enough so they have an un-obstructed view of the sky. Adjacent structures (such as trees, buildings, and antenna towers) are considered obstructions. If an un-obstructed view is not possible, you must install the GNSS units so they have a clear view of the appropriate sky region. 58 5/16 ANCHOR BOLTSQTY 6Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 2: DBR M12 MultiCarrier Site Equipment Installation Adjacent antenna towers at the RF site which protrude into the required region have a minimal effect on GNSS unit reception due to their narrow, largely open profiles and are not considered obstructions. For northern hemisphere installations, an un-obstructed view of the southern sky must be maintained. For southern hemisphere installations, an un-obstructed view of the northern sky must be maintained.

Carefully inspect all equipment and accessories to verify that they are in good condition. Promptly report any damaged or missing items to a Motorola Solutions representative. CAUTION: Do not tamper with factory configuration settings for these devices. These settings include software configuration, firmware release, password, and physical connections. Motorola Solutions has configured and connected these devices to meet specific performance requirements. Tampering with these devices may result in unpredictable system performance or catastrophic failure. 3.3.3 Placement and Spacing Recommendations Proper spacing of equipment is essential for ease of maintenance and safety of personnel. Spacing requirements have been established to meet the National Fire Protection Associations (NFPA) code, and the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) standards. Adhere to 73 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 3: DBR M12 MultiCarrier Site Installation any local regulations that apply to the installation. Placing Equipment Recommendations Place each rack on a firm, level, and stable surface, and bolt the racks together. Use the proper mounting hardware and shims to prevent rack movement. See the Standards and Guidelines for Communication Sites manual. Use strain relief when installing and positioning cables and cords to help ensure that no interruption of service occurs. Provide an appropriate amount of space around all components to allow for proper air flow, cooling, and safe access to equipment. Locate the site racks and other equipment with enough spacing to allow access for service. Locate the system in an area free of dust, smoke, and electrostatic discharge (ESD). Equipment that is not part of the defined product configurations should not be added to the rack. Extraneous hardware may compromise thermal performance by raising the temperature or impeding airflow. External cables coming into the racks must not significantly reduce airflow. For grounding racks information, see the Standards and Guidelines for Communication Sites manual. Detailed Spacing Recommendations Cabinets and racks allow equipment to be added to a site. Always consider room for expansion when setting up a site. Cabinets or racks may be installed next to each other or to other equipment. However, provide all cabinets and racks with sufficient floor space to permit access for installation and service. Front access:

At least 2 ft floor access in front of the cabinet or rack. Side and rear access:

At least 2 ft floor access at the rear of the cabinet or rack. At least 2 ft access on at least one side of the cabinet or rack, plus 6 inches at the rear of the cabinet or rack. For details on space requirements, see the Standards and Guidelines for Communication Sites manual. 3.3.4 Cabinet Bracing Recommendations Use all supplied bracing hardware when installing a rack or cabinet, and secure all equipment within a rack or cabinet. If additional equipment is installed, see the system design document the field engineer provided, or consult the Motorola Solutions Field Representative. Subsystem cabinets are self-supporting structures. In areas subject to seismic activity, additional bracing of the cabinet may be required to prevent it from tipping. However, the bracing hardware must be locally procured. No specific procedures are provided within this manual for bracing cabinets in active seismic areas. See the Motorola Solutions Standards and Guidelines for Communication Sites manual for details on seismic conditions. 74 RISK OF FIRE: Install only on concrete or other non-combustible surface.RISQUE DINCENDIE: Installer uniquement sur du bton ou toute autre surface non combustible.Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 3: DBR M12 MultiCarrier Site Installation 3.3.5 Mounting Cabinets or Racks to a Floor Perform the following steps to properly install a cabinet or open rack within a site building. Secure the cabinets and racks to the floor for optimum stability. This procedure is written so that the cabinet or rack is moved only once. Procedure:

1. Carefully mark the mounting holes with a pencil, as indicated on the appropriate cabinet or rack footprint. 2. Drill the marked mounting holes to the appropriate depth of the mounting hardware with a hammer drill and bit. 3. Insert an anchor into the drilled hole. If necessary, tap the anchor into place using a hammer. 4. For cabinets, adjust leveling feet until the mounting plate solidly touches the floor. 5. Carefully move the cabinet or rack into the position indicated by the holes in the floor. WARNING: Equipment cabinets and racks are heavy and may tip. Use extreme caution when moving. Lift from top eyenuts with the appropriate apparatus, or secure the cabinet or rack from tipping if lifting from the bottom. Failure to do so could result in death or serious injury or equipment damage. AVERTISSEMENT: Les armoires et les btis dquipement sont lourds et peuvent basculer. Soyez extrmement prudent lorsque vous les dplacez. Soulevez-les partir des crous il suprieurs avec lappareil appropri ou prvenez le basculement de larmoire ou du bti si vous le soulevez par le bas. Ne pas le faire pourrait entraner la mort, des blessures graves ou des dommages matriels. 6. Adjust and level the cabinet or rack as necessary to position the cabinet mounting holes with the pre-drilled holes. 7. Secure the cabinet or rack to the site floor with the locally procured mounting hardware. IMPORTANT: If securing a rack to a concrete floor, use 1/2-inch grade 8 bolts with anchors, for a cabinet use 5/16-inch grade 8 bolts with anchors. 8. For cabinets, adjust leveling feet until they touch the mounting surface. 3.3.6 Bonding and Grounding Requirements Cabinets and racks include a Rack Grounding Bar (RGB) with the capacity to terminate numerous ground wires, which are associated with internal metallic or fiber optic cables and external grounding to power company equipment. Attach equipment added to the cabinet or rack to the ground bar using solid or stranded 6 AWG copper wire. The RGB uses dual-hole lugs to terminate ground wires. The minimum number of dual-hole attachments is system-dependent and specified by your organization. This bar provides electrical continuity between all bonds and ground wire with a current-carrying capacity equal to or exceeding that of a 6 AWG copper wire. See the Motorola Solutions Standards and Guidelines for Communication Sites manual for more information on proper bonding and ground at a site. 75 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 3: DBR M12 MultiCarrier Site Installation 3.3.7 Cabling Requirements Diagrams for cabling are typically included in the system-specific configuration documentation Motorola Solutions provides. Also see the Motorola Solutions Standards and Guidelines for Communication Sites manual for cabling standards. IMPORTANT: System certification was completed using shielded cables. To prevent emission problems, use only shielded cables. Do not substitute other cable types. Position the equipment to avoid excessive tension on cables and connectors. Cables must be loose with absolutely no stress on the connectors. Careful cable routing and securing the cables with tie wraps (or other devices) is one way to provide this protection. Set up preventive maintenance loops. Dress the cables neatly using cable ties. Do not tighten the cable ties until you are sure that the required service length and bend radius requirements are met. Leave cable ties loose enough to allow adjustment. Verify that all cables are properly labeled to match system-specific configuration documentation Motorola Solutions provided. Ensure that cables do not exceed the minimum bend radius as outlined in the Motorola Solutions manual for cabling standards. CAUTION: Use only Category 5e Shielded Twisted Pair (or higher) for cabling Ethernet connections. Motorola Solutions has engineered this system to meet specific performance requirements. Using other cabling and connectors may result in unpredictable system performance or catastrophic failure. AVERTISSEMENT: Utilisez uniquement une paire torsade blinde de catgorie 5e (ou suprieure) pour le cblage des connexions Ethernet. Motorola Solutions a conu ce systme pour rpondre des exigences de rendement particulires. Utiliser dautres cblages et connecteurs peut entraner une performance imprvisible du systme ou une panne catastrophique. For more information on cabling guidelines, see the documentation supplied with components from each equipment manufacturer. 3.3.8 Power Guidelines and Requirements For information on providing electrical service, power budgeting, selecting batteries, and other topics for supplying power at the site, see the Motorola Solutions Standards and Guidelines for Communication Sites manual. Perform electrical installation work in accordance with the current edition of the NFPA 70 and local building codes. Where required, use a qualified and licensed electrician for all electrical installations. NOTE: In the event of a power supply failure, the AUX BUS connection configuration prevents transceivers in the chassis with the failed power supply from going offline. When the failed Power Supply is replaced, the lower transceiver card in the chassis resets automatically. The reset is needed for the transceiver to recognize the new Power Supply. Similarly, if the AC and/or DC input to the Power Supply is removed and then reconnected, the same reset scenario occurs. 3.3.8.1 AC Power Guidelines and Requirements The Motorola Solutions Standards and Guidelines for Communication Sites manual defines the guidelines and requirements for cabinets and racks which house equipment that requires AC power input. Some of the guidelines and requirements are as follows:

76 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 3: DBR M12 MultiCarrier Site Installation The cabinet or rack is designed to accept 120/240 V, single-phase power with an amperage service size as required by the electronic equipment. Cabinets and racks powered by commercial power must be equipped with a Nationally Recognized Test Laboratory (NRTL) certified power distribution module that contains a main circuit breaker, or individual circuit breakers of the correct size as required for the electronic equipment, or as specified by your organization. A decal showing an electrical schematic of the power wiring is affixed to the inside surface of the cabinet. All AC power equipment and electrical components must conform to National Electrical Manufacturers Association (NEMA) and National Electrical Code (NEC). The AC power equipment must also be listed by an NRTL. A surge arrestor, designed to protect equipment systems from a 120/240 V service and load center, is placed on the power feed ahead of all individual load center circuit breakers. This gapless arrestor must be listed by an NRTL for the purpose intended. Selection of a surge arrestor is based on the susceptibility of the equipment powered by the electrical service, with margin provided for locally generated disturbances. See ANSI/IEEE C62.41 (21) for more details. At least one 120 VAC, 15 A duplex convenience outlet equipped with Ground Fault Interrupter (GFI) protection must be provided in the electronic equipment compartment. CAUTION: Do not use surge/transient suppressors without careful and expert power system analysis. AVERTISSEMENT: Nutilisez pas de suppresseurs de surtensions/surtensions transitoires sans faire faire une analyse minutieuse du systme dalimentation par un expert. TIP: Redundant devices could be terminated on different AC main phases so that a single phase failure does not result in a power loss for both devices. 3.3.9 Electrostatic Discharge Recommendations Electronic components, such as circuit boards and memory modules, can be sensitive to Electrostatic Discharge (ESD). Use an antistatic wrist strap and a conductive foam pad when installing or upgrading the system. If an ESD station is not available, wear an antistatic wrist strap. Wrap the strap around the wrist and attach the ground end (usually a piece of copper foil or an alligator clip) to an electrical ground. An electrical ground can be a piece of metal that literally runs into the ground (such as an unpainted metal pipe), or the metal part of a grounded electrical appliance. An appliance is grounded if it has a three-prong plug and is plugged into a three-prong grounded outlet. NOTE: Do not use a computer as a ground, because it is not plugged in during installation. 3.3.10 FCC Requirements Radio frequency (RF) transmitters installed at sites within the US must be in compliance with the following FCC regulations:

The station licensee is responsible for the proper operation of the station at all times and is expected to provide observations, servicing, and maintenance as often as may be necessary to ensure proper operation. The transmitter ERP must not exceed the maximum power specified on the current station authorization. 77 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 3: DBR M12 MultiCarrier Site Installation The frequency of the transmitter must be checked during initial installation of the transmitter, when replacing modules, or when making adjustments that affect the carrier frequency or modulation characteristics. 3.3.11 Networking Tools Use the following networking tools for installing and servicing the network:

Site-specific information includes the following:

Site design drawings showing the location of racks, cabinets, cable trays, and other components Rack drawings showing the location of the equipment in each rack Cable matrix in a table format that shows each cable and its connections Interconnect wiring diagrams to show the cable connections between devices Pre-programmed parameters of each site component Templates used to program each device All firmware and software revisions of each site component Test data from each device that requires operational verification Optimization requirements and settings of each electrical path Acceptance Test Plan for the site components NOTE: Maintain this site-specific information to reflect the current site configuration and layout for the system. 3.4 Power Connections This section covers topics on connecting power cables to the DBR M12 Site and the power distribution module, calculating the length of wire for various gauges, and mounting the battery temperature sensor. 3.4.1 DC Power Connection Wire Gauge Calculations for Integrated Voice and Data Since the power supply disconnects itself from the DC input when it senses that DC voltage has dropped to 42 VDC, it is important to minimize the voltage drop in the DC power supply loop (the total length of the 48 VDC hot wire and the DC return wire) to no more than 1 V total. Minimizing the voltage drop ensures that the maximum energy is removed from the battery before disconnecting the power supply from the DC input line. A DBR M12 MultiCarrier Site rack/cabinet configured with a single 2-3 N - way combiner bank, with 6 carriers at rated RF output, can consume up to 2400W. This equates to 44A of current when operating from a 54 V source (nominal 48 VDC system). As the voltage decreases (due to the standby battery discharging) the current increases proportionally (since the base radio appears to be a constant power load). At the low voltage disconnect point (42 V for a nominal 48 VDC system), the current is up to 57 A. If a single pair of 2 AWG wires is used to connect the battery to the junction panel, the maximum length of a single conductor is 17m (55 ft). Use of smaller gauge wire would reduce the length of a single conductor, depending on the resistance of the wire. To determine the maximum length of wire for wire other than 2 AWG, you can refer to the following relationship:

Length (meter/feet) = V/I/R where:

V = voltage drop in one leg of the loop (max = 0.5 V) 80 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 MN010943A01-C Chapter 3: DBR M12 MultiCarrier Site Installation I = current drawn by the base radio during DC operation R = resistance of the wire being considered (in Ohms per meter/foot) For common wire sizes for an IV&D site, the maximum distances apply. Table 18: DC Power Connection Wire Gauge Maximum Distances for an IV&D Site AWG 1 2 4 6 Resistance (ohm/1000 ft) Maximum Distance (for 57 A) 0.1239 0.1563 0.2485 0.3951 21m (70 ft) 17m (55 ft) 11m (35 ft) 7m (23 ft) In some installations, local codes may require the installation of wire heavier than 2 AWG. In these situations, a local splice box can be used to reduce the incoming wire to the 2 AWG needed for connection to the input terminal box. The splice box should be as close as possible to the junction panel. If two pairs of 2 AWG wire are used to connect the DBR M12 MultiCarrier Site to the battery bank, the maximum distance from the battery to the junction panel would be 110 ft. If longer distances are required, a splice box must be included in the DC distribution. In that event, the following diagram provides guidance regarding the maximum distance permitted for various wire gauges available. These values are based on a splice box located 10 ft from the junction panel. If the splice box is more than 10 ft from the junction panel, the allowable distance between the splice box and the battery bank is shorter. NOTE: Each DC input termination is rated for a maximum of 65 A. Figure 45: Wire Gauge and Distance Guide 3.4.2 Connecting Power to an AC Power Source WARNING: Shock hazard. The DBR M12 MultiCarrier Site contains dangerous voltages which can cause severe electrical shock or damage to equipment. You must disable power to the system before servicing this part.

A separate circuit breaker for each power cord is needed to ensure that not more than one AC/DC power supply module loses power when a breaker is tripped or opened. All AC power breakers, wiring and receptacles must comply with the installation guidelines specified in Standards and Guidelines for Communication Sites. The DBR M12 MultiCarrier Site AC Power Supply can be ordered with one of the following power connection options:

1.8m (6 ft) NEMA 520 to IEC C19 Power Cord 3.7m (12 ft) NEMA 520 to IEC C19 Power Cord Connector Field Kit that provides 1 loose IEC C19 connector for the equipment end and the field. You must provide the proper length cable and region specific plug. Procedure:

1. Remove the power cords from the loose shipment accessories. 2. Assemble the two snap-on EMI Ferrite suppressors (HZ000947A01) to each line cord, as close to the C19 connector as possible. 3. Insert the C19 connectors into the frame power chassis in the receptacles aligned to the two Power Supply Units (PSU). 4. To retain the cable from accidental removal, place the cable retention clip over the strain relief of the C19 connector of the power cord, and squeeze it. 5. To apply power, connect the NEMA 520 plugs into a compatible wall receptacle. 3.5 Grounding Detailed grounding information is beyond the scope of this manual. See the Motorola Solutions Standards and Guidelines for Communication Sites manual for detailed information about grounding and lightning protection. IMPORTANT: Ground the battery system, either positive or negative, at the battery. The DC input

(battery charger output) of the power supply is floating with respect to earth ground. The power supply can therefore be used in either positive ground or negative ground DC systems. The appropriate terminal (+ or -) of the DC system should be connected to protective earth at the battery. These instructions assume that all telephone lines, antenna cables, and AC or DC power cables have been properly grounded and lightning-protected. When rack installations have a primary rack and one or more expansion racks, all these racks must be connected to the same Sub System Ground Bus Bar (SSGB) (and no other rack connected to the SSGB). Grounding ensures that surge events do not produce ground potential differences that affect signals between the racks. 82 Applicant: Motorola Solutions EQUIPMENT TYPE: ABZ89FT5912 / 109AB-T5912 Figure 46: Rack Grounding MN010943A01-C Chapter 3: DBR M12 MultiCarrier Site Installation Annotation Description 1 2 3 Ground BUS Conductor Irreversible Crimp Connector or Split Bolt Route Conductors Toward Ground BUS and SSGB 3.6 Junction Panel Connections The junction panel for the DBR M12 MultiCarrier Site cabinet/rack provides locations for all the non-RF connections to external devices. Cables provided by Motorola Solutions include the specific connectors for the junction panel on one end and the subsystem equipment on the other end.
