ABSTRACT:
An improved computer chassis having a backplane with ground pads thereon for contacting fingers formed in channels in the chassis. The backplane is secured in the chassis without the use of screws. The fingers are defined within channels formed by a structure at the rear of a disk drive cage. The computer system further includes a plurality of disk drives mounted on trays which have rear pins that engage guide apertures formed in the backplane. The backplane is inserted within the channels and held therein by a pair of levers on outer corners which engage with catch members on the computer chassis. The engagement between the levers and the catch members ensures the backplane will remain in position during assembly and shipping. The backplane includes ground pads connected to a ground plane within the backplane. The ground pads engage the fingers on the channels to provide a secure electrical interconnection between the chassis and the backplane. After the backplane is inserted, the disk drives are pushed into place such that the rear pins of the trays secure the backplane in position, and such that the respective electrical connectors engage.
