Abstract: An equipment rack includes a frame, a first pair of mounting rails and a second pair of mounting rails. Each pair of mounting rails includes a front mounting rail and a rear mounting rail and the front and rear mounting rails each include a first planar surface defining in part a first equipment-mounting interface when the front and rear mounting rails are coupled to the frame through a second planar surface of each of the front and rear mounting rails in a first configuration. The front and rear mounting rails each further include a third planar surface and a fourth planar surface defining in part a second equipment-mounting interface when the front and the rear mounting rails are coupled to the frame through the first planar surface in a second configuration. The first and second equipment-mounting interfaces can be defined by an equipment rack standard.

Abstract: The disclosed embodiments relate to a rack for housing electronic components with a movable power distribution unit (PDU). The rack includes a rack housing configured to accommodate a plurality of electronic components. It also includes a first PDU configured to supply electrical power to the plurality of electronic components. The rack additionally includes an attachment mechanism configured to movably attach the first PDU to the rack housing, so that the first PDU can be moved to create an access space to facilitate a maintenance operation while the first PDU continues to supply power to the plurality of electronic components.
