Patent ID: 8724330

Claim:
An apparatus, comprising: a chassis having a first end, a second end, a bracket between the first and second ends, a first slot adjacent the first end, and a second slot adjacent the second end, wherein the bracket is positioned for securing a first surface of a midplane at a known distance from the first slot, and wherein a first electronic device is selectively securable within the first end of the chassis with a first device connector coupled to the first surface of the midplane and a first device latch secured to the first slot; and a sub-chassis receivable within the second end of the chassis, wherein the sub-chassis has a proximal end that engages a second surface of the midplane, a distal end having a sub-chassis latch that selectively engages the second slot to secure the sub-chassis in the second end of the chassis with the proximal end engaged against the second surface, and a sub-chassis slot adjacent the distal end of the sub-chassis that is a known distance from the proximal end of the sub-chassis, and wherein a second electronic device is selectively securable within the distal end of the sub-chassis with a second device connector coupled to the second surface of the midplane and a second device latch secured to the sub-chassis slot.
