Printed circuit board mounting cage

DETAILED DESCRIPTION In carrying out principles of the present invention in accordance with a preferred embodiment thereof, a mounting cage for supporting a plurality of circuit board frame module assemblies comprises first and second pairs of mutually parallel and mutually spaced support panels, each of said pairs of panels extending between and fixedly interconnecting panels of the other of said pairs to define a rigid cage having a front opening framed by front edges of the panels and a rear opening framed by rear edges of said pairs.
Panels of said first pair each includes circuit board receiving guideways forming mutually opposed and aligned pairs of guideways, each pair of said guideways being configured and arranged to receive opposite edges of a circuit board.
The guideways of said first pair of panels extend from said front edges toward said rear edges, and the guideways of the second pair of panels extend from the rear edge thereof toward said front edges.
The cage carries mid-plane terminal panels bearing cable connector sockets and has its panels apertured for blowing air over stacks of circuit boards.
Two stacks of printed circuit board frame module assemblies are mounted in the cage by slidable reception of guide ribs of the frame module assemblies in sets of parallel guideways formed in facing surfaces of cage support panels.
