CIOM-A FIM versus C200 CPM redundancy 
Bo
th the CIOM-A FIM and the C200 CPM or Controller redundancy use Redundancy 
Modules in a Redundant Chassis Pair (RCP) configuration to provide redundant 
functionality. The RCP does this by providing a pair of chassis, so a component failure in 
one chassis switches the handling of the assigned functions to the other chassis. This is
