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....

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.
