Abstract
A telecommunications switch chassis includes a housing which is divided into front and rear compartments by a transverse printed circuit board or mid-plane. Notches are provided in the upper edges of the mid-plane which are adapted to receive tabs projecting from the ends of a pair of card guides so that the card guides are supported on edge in proper laterally spaced relation within the front compartment. The card guides are formed with columns of slots whose edges are deformed to form slides interleaved with the slots so that the card guides can support a stack of printed circuit cards in vertical spaced relation within the front compartment, the spaces between the cards being aligned with the slots in the card guides. Card connectors are mounted to the printed circuit board, the connectors being aligned with the slides of the card guides so that when printed circuit cards are seated in the slides, end connectors on those cards mate with the corresponding connectors on the mid-plane so that reliable electrical connections via the mid-plane are made between all of the cards in the chassis. The chassis also includes a fan module in the front compartment which directs high pressure …
