The csi 10-slot Compact Modul ar Cabinet (CMC) has a few desig n features that
can affect the system technic ian’s approach to troub leshooting:
■The CMC cabinet has 2 shelves of 5 slots each (1-5, 6-10) as shown in
Figure 1-1. This means that slots 5 and 6 are not contig uous like they are
in other DEFINITY cabinet types and that Multi-Function board s 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
TN566 board in slot 8 with the two previous and 1 next slot reserved
for AUDIX.
— MAPD requires 2 slots if administered in slot 7, other wise,
installation requires 3 slots. See ‘‘change circuit-packs’’ in Chapter
2, ‘‘Maintenance Commands’’ for more details.
■The TN798 Processor circuit pack inc orporates the RISC processor
complex, the TN777B NETCON (including PCM flash card interface), and
TN765 Processor Interface functions and i s always found in slot 1 of the A
carrier. (See Figure 1-1)
— The TN798 has 16 Mbytes of FLASH PROM for software text and 16
Mbytes of DRAM for translations and other da ta. The TN798 is the
only processor circ uit pack comp atible in the CMC.
— The processor does not have either an amb er WARNING LED nor a
green ACK LED. If there is a warning, consult the alarm log with the
display alarms command. More d etails on the processor LEDs can
be found in the ‘‘TN798 Processor Circuit Pack LEDs’’ on page
1-86.
