6.1.2 Supporting Information
The following sections provide information about functional components of
the XCRP4 Controller card.
6.1.2.1 Processors
The XCRP4 Controller card has four processors: one processor runs the
low-level software and the other three processors run the BRAS and routing
software. Support for more than one processor to run the BRAS and routing
software depends on the release of the SmartEdge OS.
6.1.2.2 Main Memory
Synchronous Dynamic Random Access Memory (SDRAM) is used by the
SmartEdge OS shared databases that are accessed by the line cards. In a
chassis with two controller cards, both cards must have the same memory
configuration
