Abstract: A system for the management of rack-mounted field replaceable units (FRUs) that affords the enhanced availability and serviceability of FRUs provided by blade-based systems but in a manner that accommodates different types of FRUs (e.g., in relation to form factors, functionality, and the like) installed within a rack or cabinet.

Abstract: A management record specification for use with a frame or other structure holding one or more field replaceable units (FRUs) such as rack-mount servers or blade enclosures that broadly allows for management of installed FRUs. The management record specification is implemented within a number of programmable read-only memory (PROM) images such as a worker PROM image stored in memory of a number of frame arms that receive or interface with respective FRUs, and a manager PROM image that is accessed by the “frame manager” of the frame. Installed FRUs access respective worker PROM images to determine their roles within the frame, physical locations, and the like. The frame manager obtains manager PROM image information to manage installed FRUs in relation to hot-swapping, firmware updates, and the like.

Abstract: A computer system comprises a plurality of shelves. Each shelf has a carrier for removably receiving a plurality of information processing modules and a switching module. Each shelf also has an interconnection member for providing connections between the information processing modules and the switching module. The switching modules of the respective shelves are interconnected in a logical stacking configuration to form a logical stacking arrangement.
