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
Figure 1 on page 39 . Slots 5 and 6 are not contiguous like they are in other
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
TN566 board must be in slot 8 with the two previous and 1 next slot
reserved for AUDIX.
— MAPD requires 2 slots if administered in slot 7, otherwise,
installation requires 3 slots. See Chapter 2, ‘‘Maintenance
Commands’’ for more details.
■
The TN2402/TN798 Processor circuit pack is installed in slot 1 of the A
carrier (see
Figure 1 on page 39 ).
— The TN2402/TN798 Processor circuit pack incorporates the RISC
processor complex, the TN777B NETCON (including PCM flash
card interface), and TN765 Processor Interface functions.
— The TN2402/TN798 has 16 Mbytes of FLASH PROM for software
text and 16 Mbytes of DRAM for translations and other data. The
TN2402/TN798 is the only processor circuit pack compatible in the
CMC1.
— The processor does not have an amber WARNING LED nor a green
ACK LED. If there is a warning, consult the alarm log with display
alarms. See
‘‘TN2402/TN798 Processor Circuit Pack LEDs’’ on
page 111 for more information.
— Four administerable netcon channels are accessible through the
TN2402/TN798 processor. They can be used for asynchronous
adjuncts such as the G3 Management Terminals (SAT) family of
Windows-based applications, BCMS terminals, BCMS VU, system
printers, PMS links, and CDR devices.
— The TN2402/TN798 has separate RS232 ports for the external
modem and CDR port.
■
The AC Power Supply Unit (650A) provides:
— Multiple DC outputs: ± 5.1 VDC, -48 VDC, +8-14 VDC (fan speed
control), and -150 to -115 VDC (Neon bus).
— Three switch-selectable AC ring outputs: 85 VAC @ 20 Hz (North
America), 72 VAC @ 25 Hz (international), and two 28 VAC @ 50
Hz (France).
— See ‘‘Power Supply LEDs’’ on page 115 for more information on
LED indicators and interpretation.
