DESCRIPTION
Hot swap, hot plug, and hot dock are terms used interchangeably to refer to hot insertion and removal. Hot swap lets you insert and remove cards, PC boards, cables, and/or modules from a host system without removing power. Because of the need for High Availability (HA) systems, hot swap has quickly become part of every designer's vocabulary. To increase system availability, hot swap is used to reduce down time, simplify system repair, and allow for system upgrade. Because of these advantages, hot-swap solutions are finding their way into a wide variety of applications.
