Abstract: Power systems and methods for supplying direct current power to a server rack via a power shelf assembly that includes multiple power supply units (PSUs) and a power shelf controller (PSC) that ensures a correct configuration of PSUs, backup battery units (BBUs), and connection components using a power shelf configuration record. Upon a boot cycle of the PSC, the configuration identified in the power shelf controller is compared to an actual configuration of the components being connected between a server rack and the power shelf assembly to avoid providing power too soon and causing an overload of components for the server rack.
