ABSTRACT:
Techniques for accommodating chassis tolerances use joiners which enable outer side panels for a front card cage to reference a front side of a midplane, and outer side panels for a rear card cage to reference a rear side of the midplane. The joiners couple the outer side panels together in a rigid but accommodating manner regardless of variations in midplane board thickness. Accordingly, both the front and rear card cages are capable of accurately and consistently referencing from the midplane sides. Not only do these techniques solve registration drawbacks which exist in conventional midplane installation approaches involving the bolting of midplanes to the middles of pre-constructed frames, these techniques further enable accurate direct connection of other components such as a power supply subsystem (e.g., to the midplane front side) and a fan assembly (e.g., to the midplane rear side) thus alleviating the need for burdensome cables.
