The CSI 10-slot Compact Modular Cabinet (CMC1) has a few design features that
can affect the system technician's approach to troubleshooting:
The CMC1 cabinet has 2 shelves of 5 slots each (1-5, 6-10) as shown in

Avaya Definity Server cabinet types. Multi-Function circuit packs such as
the TN566 and the MAPD boards (TN800, TN801, and TN802) must be
installed in specific slots. For example:
— AUDIX, if present, requires 4 slots (slots 6-9 on the top row). The
— MAPD requires 2 slots if administered in slot 7, otherwise,
The TN2402/TN798 Processor circuit pack is installed in slot 1 of the A
