Understanding Hot Swap: Example of Hot-Swap Circuit Design Process

High-availability systems, such as servers, network switches, redundant-array-of-independent-disk (RAID) storage, and other forms of communications infrastructure must be designed for near-zero downtime throughout their useful life. Components that fail or need updating must be replaced without interrupting the rest of the system. This process, known as hot-swapping or hot-plugging, requires a hot-swap controller.
