SYSTEM CONFIGURATION - U SLOT
U Slot Default Settings
If you have a U Slot system (software version 02.**.**), fol-
lowing are the default configurations. If you have a fixed slot
system (software 01.**.**), turn to page 1-20.
4 Slot Cabinet with CPU P/N 80025
Default configuration: 16 trunks x 32 extensionsSlot CN1 = 16 DSTU PCB (Extensions 300-315)
Slot CN2 = 16 DSTU PCB (Extensions 316-331)
Slot CN3 = 8 ATRU PCB (Trunks 1-8)
Slot CN4 = 8 ATRU PCB (Trunks 9-16)

4 Slot Cabinet with CPU P/N 80025A
Default configuration: 0 trunks x 64 extensionsSlot CN1 = 16 DSTU PCB (Extensions 300-315)
Slot CN2 = 16 DSTU PCB (Extensions 316-331)
Slot CN3 = 16 DSTU PCB (Extensions 332-347)
Slot CN4 = 16 DSTU PCB (Extensions 348-363)
Notes on this configuration:
1. Slots CN5-CN8 are not available.
2.You cannot install this configuration as is;it has too many
16DSTU PCBs. You must use 9902: Slot Controlto recon-
figure your PCBs. See your system’s Release Notesor
Software Manualfor more on using 9902: Slot Control.

8 Slot Cabinet with CPU P/N 80025A
Default configuration: 24 trunks x 80 extensionsSlot CN1 = 16 DSTU PCB (Extensions 300-315)
Slot CN2 = 16 DSTU PCB (Extensions 316-331)
Slot CN3 = 16 DSTU PCB (Extensions 332-347)
Slot CN4 = 16 DSTU PCB (Extensions 348-363)
Slot CN5 = 16 DSTU PCB (Extensions 364-379)
Slot CN6 = 8 ATRU PCB (Trunks 1-8)
Slot CN7 = 8 ATRU PCB (Trunks 9-16)
Slot CN8 = 8 ATRU PCB (Trunks 17-24)
Notes on this configuration:
1. This configuration requires 3 power supplies.
2. 8 Slot cabinets requireA version PCBs.

SYSTEM CONFIGURATION - FIXED SLOT
Fixed Slot Configuration Guidelines
Fixed Slot systems use software version 01.**.**. The maxi-
mum configuration of your fixed slot system is 16 trunks and
32 extensions. Also see Where to Install the PCBs in your Fixed
Slot Systemon page 2-5.
Load factor in your fixed slot system is an issue only if you
have DSS Consoles and 2-OPX Modules installed (see the
System Load Factor Calculationschart on page 1-18).
Exceeding the load factor will cause your system’s
power supply to automatically shut down.
Fixed Slot Default Settings
If you have a Fixed Slot system (software version 01.**.**),
following is the default configuration. If you have a U Slot sys-
tem (software 02.**.**), turn to page 1-17.
4 Slot Cabinet with Fixed Slot Software and
CPU P/N 80025
Default configuration: 16 trunks x 32 extensionsSlot CN1 = 16 DSTU PCB (Extensions 300-315)
Slot CN2 = 16 DSTU PCB (Extensions 316-331)
Slot CN3 = 8 ATRU PCB (Trunks 1-8)
Slot CN4 = 8 ATRU PCB (Trunks 9-16)Notes on this configuration:
1. You can plug DSTU PCBs only into slots CN1 and CN2. 
1. You can only plug an ASTU PCB only into slot CN2 (in
place of the second DSTU PCB).
2. Install ATRU PCBs only into slots CN3 and CN4.
Notes for Fixed Slot Software

Fixed slot (01.nn.nn) software is only compatible with 4 slot cabinets.

Fixed slot software is no longer available, but you may encounter it in existing installations.

You can plug 16DSTU PCBs only into slots CN1 and CN2. Do not install more than 2 
16DSTU PCBs under any circumstances.

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.

System Load Factor in Fixed Slot systems is only an issue if you have DSS Consoles and 2-
OPX Modules installed. Note that you cannot install more than 4 DSS Consoles, regardless 
of System Load Factor.

The Release Notes that came with your system indicate if it uses Fixed Slot software.

Check your system s Hardware Manual for more installation details.

Maximum con guration for 4-slot cabinets with Fixed Slot software is 
16 trunks
, 32 exten-
sions
 and 
48 ports
.
