Control Cards
Table 4: Control Cards
Card Important Details
Main Controller II E Provides 8 Mbytes of RAM if system is running software version
M21.0 or earlier. If the system is running software version M21.1 or
later, it provides 15 Mbytes of RAM, and therefore the control RAM
II cards must be removed.
Main Controller III or
Main Controller III R
Provides 16 Mbytes of RAM.
Main Controller III E Provides 16 Mbytes of RAM if system is running a software version
between P02.3.2 and Q10.7.14 (must be programmed as MCIIIr).
If the system is running software version Q10.5 or later, it provides
32 Mbytes of RAM and built-in Ethernet connection.
Circuit Switch Matrix II Increases main controller’s circuit switch size from 24 x 24 circuit
switch links to a 48 x 48 non-blocking link matrix. It is required in a
redundant system.
Control Resource Card Required in SX-2000 LIGHT non-redundant and redundant
systems.
Control Resource Card II This card is required in the SX-2000 MICRO LIGHT system but
can be used as a replacement for the control resource card in
SX-2000 LIGHT non-redundant and redundant systems.
Control Resource Card III This card is required for systems that use the OPS Manager ETI
interface.
Peripheral Switch
Controller Card
This card performs all peripheral switch functions for up to 12
Peripheral Interface Cards.
Peripheral Resource Card Peripheral nodes that use a PSCII have PRC functionality built in.
One or two peripheral resource cards are installed in each DSU
node.
