The power management module is cabled to the server blade enclosure management module(s) to facilitate communication of management information, such as server blade and interconnect location, power supply budget, and health status. • Investment protection-All current and future server blades and interconnect options can be used with any of the power subsystem options. • Tooless installation and serviceability-power enclosures are easily installed with spring-loaded rack rails and thumbscrews. 30
