Carefully open each rack and inspect the 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  Harris  representative  if  the  damage  is  such  that installation cannot proceed. 4.3  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. Each 19” rack mounted assembly  typically has a grounding point identified on the assembly.  Use this location to ground each sub-assembly to the cabinet or rack ground bus bar.  Properly ground the bus bar to the building or room’s ground system. Transmission lines, telephone equipment, HVAC equipment, door frames, and any other metallic objects located in and around the facility must be properly grounded per the site grounding manual. CAUTION
    14222-5000-3000 21 4.3.1  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.  PolyPhaser®  or  similar  SPD  devices  are  required  for  all  RF,  phone,  or  on-site control  lines  entering  the  building  from  external  sources.  For  GPS  antenna  installation,  Harris recommend using a GPS surge arrestor, part number HD-TM1M-02, inline with each GPS antenna. 4.4  INSTALLING THE EQUIPMENT The HDT300 is designed to be installed in a 19-inch rack or cabinet.  A ground bus bar should be utilized to minimize ground loops and the potential for electrical surges, such as lightning, from traveling through the equipment while dissipating to the grounding system. Carefully pre-plan the rackup, locating the fan shelf directly under each transceiver shelf, and ensuring adequate air flow above and below the rackup.  It is also recommended to install the modules after the shelf is fully installed, the grounding bus bar system is fully installed and the bus bar is properly grounded to the site grounding system. Additionally, it may be beneficial to begin installing equipment from the bottom of the rack or cabinet and building up the rail.  It is recommended to follow the steps shown in the following sub-sections when installing equipment.   The first transceiver and fan shelf installation supports the first four (4) RF channels.  For sites with five (5) or more RF channels, multiple transceiver and fan shelf installations are preformed.  Typically, two (2)  individual  rackups  consisting  of  a  transceiver  shelf,  fan  shelf,  and  EIB  may  be  installed  per  the average tall  rack  or  cabinet  (supporting RF channels 1  through  8).    For  RF  channels  9 through 16,  a second cabinet or rack is typically required. 4.4.1  Installing the Fan Shelf 1. Determine  the  installation  location along  the  rails  and  if  required,  install screw  clips  in  the  two  (2)  screw locations. 2. Install screws in the two (2) mounting locations.  3. Install a ground wire from the fan shelf rear panel to the ground bus bar. For  best  performance,  equipment ground  wires  should  be  constructed using  UL-listed  compression-type connectors  and  14-gauge  or  larger stranded  ground  wire.    Always  use gradual  bends  in  the  wire  (no  sharp angles).  4. Set DIP Switch S3 for the proper shelf identity per the following instructions:  DIP Switch S3 is used to associate the fan shelf to the corresponding transceiver shelf.  The DIP switch settings are described in Table 4-2.  Section S3-3 is the Least Significant Bit (LSB) and S3-4 is the Most Significant Bit (MSB).  Fan shelves 1 through 4 are assigned Logic 0 through 3, respectively.

Install  screws  in  all  eight  (8) mounting locations.
    14222-5000-3000 23 3. Install  a  ground  wire  from  the  transceiver shelf to the ground bus bar. For  best  performance,  equipment  ground wires should be constructed using UL-listed compression-type  connectors  and  14-gauge or larger stranded ground wire.  Always use gradual bends in the wire (no sharp angles).  4. Set  DIP  Switch  SW1  for  the  proper  shelf identity per the following instructions:  DIP Switch  SW1  is  used to  identify the  transceiver shelf  to  the  BSCU.    The  DIP switch  settings are described in Table 4-3.  Transceiver Shelves 1 through 4 are assigned Logic 0 through 3, respectively, using  SW1-1  and  SW1-3.    Section  SW1-1  is  the  Least  Significant  Bit  (LSB)  and  SW1-3  the  Most Significant Bit (MSB).  .  Sections SW1-2 and SW1-4 are not used.  NOTE The DIP switch is mounted in an inverted position.  SW1-1 is actually the right-most position as viewed while facing the rear panel.

14222-5000-3000     24 4.4.3  Installing the Extended Interface Board 1. Determine the installation location and install using the six (6) screw locations.  2. Install  a  ground  wire  from  the  EIB  panel  to  the ground bus bar. If possible, install the ground lug to the rear of the EIB  panel  where  the  surface  is  not  painted.  Alternately, remove paint from around  one hole on the front of the panel’s mounting flange. For  best  performance,  equipment  ground  wires should be constructed using UL-listed compression-type  connectors  and  14-gauge  or  larger  stranded ground wire.  Always use gradual bends in the wire (no sharp angles).  4.5  CABLE CONNECTIONS Figure 4-1 represents a 4-channel rackup.  Up to four (4) rackups similar to that shown in Figure 4-1 may be connected for a maximum of 16 RF channels at one site.  Backplane connections at each of the four rackups are similar with only cable additions for interconnecting the multiple rackups. 4.5.1  Initial Backplane Cable Connections Before  installing  cables,  the  equipment  shelves  and  grounding  system  should  be  installed  as  per  the previous sub-sections.

    14222-5000-3000 27 4.6  INSTALLING MODULES  WARNING Some  components  of  the  power  system  carry  hazardous  voltage  in  operation. Direct or indirect contact through moist objects with these components will result in fatal injury.  WARNING Make sure all AC input power is turned off to the equipment and the power switch on each PSU is set to the Off position before installing the PSU modules.   The  ESD  symbol  calls  attention  to  procedures,  practices,  or  the  like,  which  could expose equipment to the effects of Electro-Static Discharge. Proper precautions must be taken to prevent ESD when handling circuit boards or modules. Cabinets  and  racks  may  be  pre-racked  and  tested  in  a  shop  or  staging  environment;  however,  the Momentum modules and fan drawers must be removed from the shelves before transporting the rackup.  This will prevent damage to the shelf units and modules.  CAUTION DO NOT transport a pre-assembled rackup without first removing the modules and fans from the shelf assemblies.  The weight of the installed modules and fan drawers can potentially damage the shelf assemblies during transport. 1. Install the modules into the shelf slots as shown in Figure 4-5 per the following instructions: a. Loosen the two ejectors by pressing the red locking mechanism to release the ejectors (refer to Figure 4-3).  Figure 4-3: Loosening the Ejector b. Slide the BSCU along the guide rails smoothly as shown in Figure 4-4. c. Re-latch the ejectors after the module is fully inserted into the card cage. d. Tighten the screw located within each ejector. e. Tighten the screw on the top and bottom-right corners of each module as shown in Figure 4-4.

    14222-5000-3000 29 4.7  FRONT PANEL CONNECTIONS 4.7.1  RF Antenna Connections The CHU modules include RF connections for the RX and TX antennas.  Cables for each connection are customer supplied and must be high grade, low loss cables.  Cable lengths should be kept as short as possible to minimize cable loss; however, it may be desirable to use the same type cable for each similar connection and similar lengths to minimize imbalances between channels during operation. 4.7.2  GPS Receiver Antenna Connections The GPS receiver input on each BSCU module is a non-powered antenna connection.  A GPS antenna, part number HD-TM1M-01, is available and may be ordered through the Harris representative for the HDT300 system.  A GPS antenna surge arrestor, part number HD-TM1M-02, should be installed along with each GPS antenna.  If both BSCU modules are installed, the GPS antenna inputs may be connected to  separate  GPS  antennas  (desired  method,  antennas  not  supplied)  or  connected  to  a  common  GPS antenna using a customer supplied power splitter/multicoupler. Follow all manufacturers’ instructions for installing and connecting the GPS antenna to the BSCU.  Cable lengths should be kept as short as possible to minimize cable loss.  Any recommended maximum antenna cable lengths should be observed.  For installations requiring longer than recommended cable lengths, an amplified antenna system is recommended or use an inline RF antenna amplifier designed specifically for GPS antenna systems. 4.7.3  Additional front panel connections  Additional front panel connections for RS232 and other ports are used during setup and configuration and out of the scope of this manual.
