A rigid rectangular frame module (44,66,52,80) mounts a printed circuit board (40) and provides a number of edge connector nodes (46) mounted in a multi-connector node carrier (110) forming one structural element of the frame. Service cables, including power lines (200) and input/output fiber optic lines (202) are carried in a guide channel (80) at one side of the frame and coupled to a service cable connector plug (154) fixed in the frame adjacent the multi-connector node carrier (220). Locking cams (210) in frame handles (60,62) are lever actuated to firmly position the frame in a support structure to enable interconnection of its edge mounted connector modules (46) with edge mounted connector modules of a plurality of similar frame mounted printed circuit boards. The printed circuit board and frame module assembly is arranged for use in a closely packed stack (22) of such printed circuit board and frame module assemblies. The frame is configured and arranged to protect the stack of circuit boards and to allow cooling air flow therebetween. Two mutually perpendicular stacks of such printed circuit board and frame module assemblies are mounted in a four sided cage (290,292,294,296) that holds the boards of each stack in direct edge to edge connection. Threaded devices (168,180) force the service cable connector plug (154) into engagement with a service cable connector receptacle (32) carried by the cage. Screw actuated power and fiber optic interconnections (154,32) are provided for connection of electrical power and fiber optic input/output signals.
