Disclosed is a chassis comprising an enclosure, a power supply assembly mounted in the enclosure and a backplane assembly mounted in the enclosure in abutting relationship with the power supply assembly; the backplane assembly having a plurality component connectors mounted thereon and a plurality of stand-off posts protruding therefrom, each of the stand-off posts including a first aperture and being electrically coupled to one of the component connectors; the power supply including a panel with a plurality of electrical contacts disposed thereon, each of the electrical contacts having a second aperture; and a plurality of screws disposed through the first and second apertures for securing the electrical contacts of the power supply to the stand-off posts of the backplane assembly.

Power supply connection system

A VXI chassis which has user selectable or configurable slot 0 locations. The VXI chassis includes a personality module interface coupled to the VXI backplane comprised in the chassis. The personality module interface or slot is adapted to receive a personality module. The personality module can be inserted into the personality module interface or slot in one of a plurality of orientations. Based on the orientation of the inserted personality module, the personality module is operable to selectively route signals on the backplane to enable one of a plurality of locations to operate as the slot 0 location. In the preferred embodiment, the VXI chassis can house a plurality of C size and/or B size VXI/VME cards, and the VXI chassis is configurable between different slot 0 locations for different size cards, i.e., between either a C-size or B-size slot 0 controller. Thus the VXI chassis of the present invention provides an innovative solution for using both C-size VXI and B-size VXI/VME resources in a single system. The selection of a C-size or B-size slot 0 controller provides increased options to the user and reduces system costs.
