Circuit card with separate interfaces for different bus architectures

A circuit card assembly for removable attachment to either a bus of a first type through a connector of a first type, having a first card locating surface engaging a circuit card fully inserted into said connector of a first type, and to a slotted bracket of a first type adjacent said connector of a first type, with said slotted bracket of a first type including an access slot offset through a first offset distance in a first direction from an adjacent side of a card inserted within said connector of a first type, or to a bus of a second type through a connector of a second type, having a second card locating surface engaging a circuit card fully inserted into said connector of a second type, and to a slotted bracket of a second type adjacent said connector of a second type, with said slotted bracket of a second type including an access slot offset through said first offset distance in a direction opposite said first direction from an adjacent side of a card inserted within said connector of a second type, bracket of a first type and said slotted bracket of a second type each additionally including a bracket attachment surface, with said first card locating surface being displaced at a second offset distance from said bracket attachment surface of said slotted bracket of a first type, with said second card locating surface being displaced at a third offset distance from said bracket attachment surface of said slotted bracket of a second type, and with said circuit card assembly comprising:

• a circuit card having parallel longitudinal edges extending between front and rear ends;
• a first connector structure for removably engaging said connector of a first type, extending along a first of said longitudinal edges, including a first connector locating surface engaging said first card locating surface;
• a second connector structure for removably engaging said connector of a second type, extending along a second of said longitudinal edges, including a second connector locating surface engaging said second card locating surface wherein said first and second connector locating surfaces are separated by a first separation distance;
• a bracket mounting structure providing a mounting surface extending perpendicularly to a surface of said circuit card and extending perpendicularly to said parallel longitudinal edges thereof;
• and
• a bracket including an attachment feature for engaging said bracket attachment surface, wherein said bracket is removably fastened to said bracket mounting structure and repositionable thereon at first and second bracket positions, wherein said second bracket position is rotated 180 degrees on said mounting surface from said first bracket position about an axis of rotation extending perpendicularly from said mounting surface, wherein said axis of rotation is offset from an adjacent side of said circuit card through said first offset distance, and wherein said axis of rotation is offset along said surface of said card from said first connector locating surface by a distance equal to half a sum of said first separation distance and a difference between said second and third offset distances.
