1. Installing the Cabinet 1-11 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. Figure 1-9 POWER SUPPLY Figure 1-10 Installing the Power Supply 80000 - 29 POWER SUPPLY INSTALLATION
1-12 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.

INSTALLING PCBs 2-4 Installing the CPU(Figures 2-3 and 2-4) CPU PCB installs in the CN0 slot in the Main Equipment Cabinet. To install the CPU PCB: 1. Slide the Mode Switch to the RUN position (see Figure 2-3). 2. Insert the battery into the battery clips. 3. Plug the CPU into slot CN0 (see Figure 2-4). Refer to Part 4, Installing Optional Equipmentfor instructions on connecting the music source, External Paging and the auxiliary relay.

2. PCB Installation 2-5 INSTALLING PCBs Digital Station (16DSTU) PCB(Figures 2-5 and 2-6) The 16DSTU provides connection for 16 digital telephones. Refer to Section 3, Installing Extensions and Trunksfor wiring instructions.To install the 16DSTU PCB: 1. Plug the 16DSTU PCB for exten- sions 300-315 into slot CN1. 2. Plug the 16DSTU PCB for exten- sions 316-331 into slot CN2. 3. Set the mode switch on each installed 16DSTU to RUN. Figure 2-5 DIGITAL STATION (16DSTU) PCB Figure 2-6 INSTALLING THE 16DSTU PCB 80000 - 31 Mode Switch
INSTALLING PCBS 2-6 Analog Station (8ASTU and 4ASTU) PCBs (Figures 2-7 and 2-8) The 8ASTU PCB provides connection for 8 analog extensions. The 4ASTU PCB provides connection for 4 analog extensions. Refer to Section 3, Installing Extensions and Trunksfor wiring instructions.To install the ASTU PCB: 1. Plug the ASTU PCB into slot CN2. With an 8ASTU PCB, this pro- vides extensions 316-323. With a 4ASTU PCB, this pro- vides extensions 316-319. You should reserve slot CN1 for a 16DSTU PCB. 2. Set the mode switch on the ASTU to RUN.

2-8 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.
