    Installing the Power Supply (Figures 1-9 and 1-10)
    The power supply provides the
    DC power sources required to
    operate the system:
    1. Slide the power supply into the
    CN101 slot as shown at right.
    2. Using a long-shaft phillips
    head screwdriver, tighten the
    two screws that secure the
    power supply.

    System Configuration
    Your cabinet uses fixed slot software. This means:
    You can plug DSTU PCBs only into slots CN1 and CN2.
    
    You can plug an ASTU PCB only into slot CN2 (in place of
    the second DSTU PCB).
    
    Install ATRU PCBs only into slots CN3 and CN4.
    Load Factor
    
    Load factor in your fixed slot system is an issue only if you
    have DSS Consoles and 2-OPX Modules installed (see the
    load factor chart below). Exceeding the load factor will cause
    your system’s power supply to automatically shut down.
    
    The maximum configuration of your fixed slot system is 16
    trunksand 32 extensions.

    Caution
    Do not plug in the CPU PCB hot (i.e., with the
    system power applied).
    You can plug in ASTU and ATRU PCBs hot as
    required.
    You can plug in DSTU PCBs hot provided you
    first disconnect the station cabling from the PCB.

    CONNECTING BLOCKS
    Working With 8-Pin Jacks
    The system uses 8-pin mod jacks to connect extensions, trunks
    and optional equipment. Using the Installation Cable (P/N
    80892) makes it easy to connect the PCBs to standard 66M1-50
    connecting blocks. These cables have 6 8-pin modular jacks on
    one end and are unterminated on the other. In general, each cab-
    inet needs:
    One 66M1-50 block and Installation Cable (P/N 80892) for
    extensions and optional equipment.
    
    One 66M1-50 block and Installation Cable (P/N 80892) for
    trunks.
    Note:Depending on your PCB configuration and local codes,
    you may need an additional 66M1-50 block and
    Installation Cable (P/N 80892) for optional equipment.
    Punching Down the Cables (Figures 2-11 to 2-14)
    The Installation Cables have 6 8-pin jacks installed on one end
    and are unterminated on the other. Each 8-pin jack connects 4
    extensions or 4 trunks.
    1. For each 66M1-50 block, punch down the Installation Cable
    in standard color-code order.
    Use Figure 2-11 when connecting extensions.Use Figure 2-12 when connecting trunks.
    2. After you have punched down your cables, route them
    through the side of the cabinet and secure them with the
    strain relief (Figure 2-13).
    3. Following Figure 2-14, snap an RFI Suppressor Assembly
    around each 50-pin cable.
    Making your own Cables (Figure 2-15)
    If you want to make your own cables (instead of using
    Installation Cable P/N 80892), follow the pinouts in Figure 2-15.
