Abstract: A redundant pair of interconnected board sub-assemblies have substantially the same dimensions and level of functionality. A module interconnect card is configured to mechanically and electronically connect to the first and second board sub-assemblies. Each sub-assembly is configured (e.g., via a properly configured microcontroller) to compensate for a loss of functionality in the other sub-assembly. Each subassembly preferably includes a re-usable adapter card that interfaces with a first card such that components requiring a lower certification level—e.g., commercial off-the-shelf (COTS) components or the like—may be isolated on the first card, wherein the adapter card includes high certification-level parts and communicates with the first card. The two cards are electronically and mechanically coupled to form the finished board assembly.

Abstract: A re-usable adapter card interfaces with a first card such that components requiring a lower certification level—e.g., commercial off-the-shelf (COTS) components or the like—may be isolated on the first card, wherein the adapter card includes high certification-level parts and communicates with the first card. The two cards are electronically and mechanically coupled to form the finished board assembly. The interface card may be re-used in a variety of current or future cabinet specifications, including, for example, cabinets manufactured in accordance with the Compact PCI (cPCI) 3U and 6U specifications.
