Abstract
This failure management system architecture guides, detects, validates and logs field replaceable unit (FRU) changes. This system includes a guided capability by which service personnel use the guided process to select candidates for FRU swaps or FRU replacement. FRU change and swap detection is described as a function of FRU memory scanning coupled with embedded database query activity. For swap activity virtual Composite Failure Events are created to manage post-swap failures. Validation logic determines whether the changed FRU is positioned correctly, is at the correct hardware, software and feature level, executes diagnostics correctly and performs flawlessly during monitored and extended functional operation.
