Abstract
A circuit pack blank occupies an unequipped position in an electronic equipment shelf that is cooled by forced-air convection. The blank incorporates two diffuser blades that protrude into a cooling space in the shelf adjacent to the blank. When air is forced through the cooling space at a constant velocity, a backpressure is generated that is equivalent to backpressures generated at cooling spaces adjacent to equipped positions. In addition, the blank has a faceplate that incorporates one or more cable trays used to retain cables at the unequipped position for future use.
Claims16
A circuit pack blank for use in an unequipped position in an apparatus shelf, the blank comprising:
- a base for positioning the blank in the unequipped position;
- and
- a diffuser blade attached to and positioned on the base, said diffuser blade arranged to substantially reduce the effective cross-sectional area of an air plenum that is adjacent to and partially formed by the base when the blank is placed in the unequipped position.
A circuit pack blank for use in an unequipped position in an apparatus shelf, the blank comprising:
- a base for positioning the blank in the unequipped position;
- a diffuser blade attached to and positioned on the base, said diffuser blade arranged to substantially reduce the effective cross-sectional area of an air plenum that is adjacent to and partially formed by the base when the blank is placed in the unequipped position;
- and
- a faceplate that includes a substantially planar member perpendicularly attached at an edge of the base, wherein the faceplate provides a means for inserting and removing the apparatus blank from the apparatus shelf.
A shelf for housing electronic apparatus, the shelf comprising:
- a frame;
- an apparatus guide that is attached to the frame;
- a blank;
- the blank including
- a base, having an edge held by the apparatus guide to position the blank in an unequipped position of the shelf, and
- one or more diffuser blades attached to and positioned on the base;
- an air plenum adjacent to the blank and formed by said base and the frame;
- and
- the blank arranged in the frame so that said one or more diffuser blades substantially reduces the effective cross-sectional area of said air plenum.
