Title: ASSEMBLY FOR HIGH-SPEED INTERCONNECTION OF DIGITAL ELECTRICAL COMPONENTS
Abstract:
A modular cable backplane assembly for high-speed interconnection of digital electrical components in Field Replaceable Units, FRUs, (12) mounted in an equipment rack (10). A vertical stack of a plurality of parallel horizontal cable connector carrying trays (51) is mounted within a rigid chassis (32). The trays provide electrical component connector pins on a front side and high-speed data and power cable connectors on a back side thereof. At least one enclosed vertical channel (21) is attached to the vertical stack of horizontal plates (51) for protectively routing cables to the cable connector carrying trays. Vertical spacing of the cable connector carrying trays enables cooling fans (41) mounted on the rigid chassis to provide unimpeded front-to-back airflow over the FRUs (12). The cable backplane assembly may be removed and replaced as a unit, and may be upgraded, in situ, from copper to optical connections.
