Abstract: A power supply and circuit module includes a housing, a power supply and a circuit module received in the housing. The power supply and the circuit module can be removably installed into and removed from a cage of an electronic system as a unit by a sliding action. The cage includes a first bottom plate, a backplane connected to the first bottom plate. A plurality of standoffs are formed on the first bottom plate for supporting a motherboard thereon. An electrical connector, such as a card connector, is directly formed on the backplane for connecting a circuit card.

Abstract: A circuit card for a data processing system includes a printed circuit board (PCB) and a carrier. The PCB includes opposing sides parallel to a mounting direction when the PCB is installed to a cage. The carrier is attached to the PCB and includes at least one guiding member offset from a normal direction of the PCB and guiding installation of the PCB in the cage. The cage includes a plurality of support plates extending along a first direction and aligned along a second direction perpendicular to the first direction of the cage to define a plurality of air flow channels. When the circuit card is mounted to one of the support plates by engaging the guiding member to the support plate, the PCB is offset from the support plate and located right in the air flow channel without being obstructed by the support plate.
