Patent ID: 8817463

Claim:
A rack for housing electronic components with a movable power distribution unit (PDU), comprising: a rack housing configured to accommodate a plurality of electronic components; a first PDU configured to supply electrical power to the plurality of electronic components; an attachment mechanism configured to slidably mount the first PDU to the rack housing so that the first PDU can slide to create an access space to facilitate a maintenance operation while the first PDU continues to supply power to the plurality of electronic components; a second PDU fixedly attached to the rack housing and also configured to supply power to the plurality of electrical components, wherein the second PDU is an inner PDU which is located closer to the plurality of electronic components than the first PDU; wherein when the first PDU is in a normal-operating position abutting to the rack housing, the first PDU restricts access to the second PDU; and wherein slidably moving the first PDU away from the normal-operating position creates the access space between the first PDU and the rack housing to facilitate a maintenance operation for the second PDU, wherein the second PDU remains fixedly attached to the rack housing while the first PDU slidably moves away from the rack housing to create the access space between the first PDU and the rack housing.
