Abstract
Substantial reduction or total elimination of switching transients (glitches) in an information handling system caused by inserting and/or removing hot-pluggable nodes having large power requirements is achieved with a plurality of power supplies having spare power capacity and being configurable into a main power source and an isolated power source. When insertion of a new hot-pluggable node is detected, this newly inserted node is powered from the isolated power source that is not coupled to the other existing operational nodes. When power to the new hot-pluggable node has stabilized and no longer has any detectable transients thereon, the new node is coupled to the main power source which powers the existing nodes of the information handling system. The isolated power source may thereafter be coupled to the main power source for added power supply redundancy. The new node may be detected and made part of or removed from the information handling system without being coupled to the main power source. When an operating node to be removed is detected, all processes to that node are stopped, and the node to be removed is coupled to the isolated power source. After removal of the node, the isolated power source may thereafter be coupled to the main power source for added power supply redundancy.
