An assembly for mounting printed circuit boards (11), which are interconnected via an electrical backplane (25) includes a housing (23), into which the backplane (25) and boards are insertable via a frontal access aperture (35). The size and shape of the backplane (25) is such that forward portions (39a, 39b) thereof have their free ends juxtaposed the forward wall portions (41a, 41b) of the housing (23) and fastened thereto. To protect the boards from environmental contamination and external electromagnetic radiation, the frontal access aperture (35) has an associated closure member (not shown). To facilitate maintenance, both the boards and the electrical backplane (25) are removable through the access aperture (35) of the housing (23). The upper and lower walls (57a, 57b) of housing (23) are provided with a plurality of liquid cooling channels. <IMAGE> |
