Module Configurations
The CESM supports the following module configurations:
• Standalone.
• 1:N card set redundancy, without bulk distribution.
• 1:N card set redundancy, with bulk distribution—For line redundancy to be supported in this
configuration, there must be redundant PXM1E or PXM45 cards and redundant SRME cards. The
APS connector must be installed between the SRME cards.
• Bulk distribution.
Note For module configuration information, refer to Chapter 4, “Planning for Card Redundancy, Line
Redundancy, and Bulk Distribution”.
