4-Slot Cabinet Default Configuration
Note:
Always observe the System Load Factor when configuring your system.
In a 4-slot cabinet, you can install either A series PCBs or non-A series PCBs. If
you install non-A series PCBs, you must install the RFI Suppressor Assemblies as
shown in your Hardware Manual. If you install A series PCBs, you do not need to
install the RFI Suppressor Assemblies on your extension and trunk cabling. The
available PCBs are:
●
CPU PCB P/N 80025A and 80025
●
Power Supply P/N 80005A and P/N 80005
●
16DSTU Digital Station PCB P/N 80021A and 80021
●
8 ASTU 8 Port Analog Station PCB P/N 80041A and 80041
●
4ASTU 4 Port Analog Station PCB P/N 80040A and 80040
●
8ATRU 8 Port Analog Trunk PCB P/N 80011A and 80011
●
4ATRU 4 Port Analog Trunk PCB P/N 80010A and 80010
If your 4-slot cabinet is using CPU PCB P/N 80025, it automatically loads a
unique 4-slot version of system software. This software supports:
●
Slots 1-4
●
24 trunks (maximum)
●
40 extensions (maximum)
●
48 ports (maximum)
●
2 16DSTU PCBs (maximum)
Following is the default PCB configuration for this unique 4-slot cabinet system
software:
If your 4-slot cabinet is using CPU PCB P/N 80025A, your system will automati-
cally load the 8-slot version of system software during startup (see below).
Review the default configuration above to see if it meets your site requirements. If
