Circuit card and cage arrangement with improved cooling

摘要

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.

主权项

1. A circuit card comprising:
a printed circuit board (PCB) having a PCB surface, a normal direction defined normal to the PCB surface, and including opposing sides parallel to a mounting direction when the PCB is installed to a cage; and a carrier attached to the PCB and including at least one guiding member offset from the PCB in the normal direction, the guiding member defining a slot for guiding a support plate of a cage into the slot so as to mount the PCB to the support plate, the slot being parallel to and open in the mounting direction.
