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

A computer system comprising:

• a chassis at least partially defining an interior and an access opening;
• an interface connector mounted within or adjacent said chassis and oriented to face the interior of said chassis;
• a circuit board assembly configured for insertion into and removal from said interior of said chassis through said access opening and along an insertion axis, said circuit board having a connector oriented for engagement with said interface connector;
• and
• a mounting assembly positioned to facilitate engagement of said connector of said circuit board assembly to said interface connector along a connection axis angled with respect to said insertion axis, said mounting assembly having:
• a tray mounted for movement with respect to said chassis along said connection axis, said tray being configured to receive said circuit board assembly along said insertion axis;
• and
• a cam mechanism having:
• a cam body;
• a lever movable with respect to said cam body;
• a cam follower extending from said lever or said cam body for guided movement with respect to a cam surface of said cam body or said lever;
• and
• a cam follower extending from said tray or said cam body for guided movement with respect to a cam surface of said cam body or said tray.

• a tray engaging said circuit board assembly, said tray being mounted for movement with respect to said chassis along said connection axis, said tray being configured to receive said circuit board assembly along said insertion axis and to move said circuit board assembly relative to said chassis along said connection axis;
• and
• a cam mechanism coupled to said tray and configured to move said tray along said connection axis, said cam mechanism having a cam body coupled for movement with respect to said chassis and a lever coupled for pivotal movement with respect to said chassis and for engagement with said cam body to facilitate movement of said cam body with respect to said chassis, wherein said cam body translates said pivotal movement of said lever to said movement of said tray along said connection axis.
