Method and apparatus for installing a printed circuit assembly within a chassis of a computer system

A computer system is provided with a chassis at least partially defining an interior and an access opening. The computer system is also provided with an interface connector mounted within or adjacent to the chassis and oriented to face the interior of the chassis. A circuit board assembly is configured for insertion into and removal from the interior of the chassis through the access opening and along an insertion axis, wherein the circuit board assembly has a connector oriented for engagement with the interface connector. The computer system also includes a mounting assembly positioned to facilitate engagement of the connector of the circuit board assembly to the interface connector along a connection access angled with respect to the insertion axis. The mounting assembly has a tray mounted for cam-activated movement with respect to the chassis along the connection axis, wherein the tray is configured with channels to receive rails of the circuit board assembly along the insertion axis and to move the circuit board assembly relative to the chassis along the connection axis to join the circuit board and interface connectors.
