Abstract: A subrack assembly (1) comprising a subrack (3) comprising two top rails (9), two bottom rails (7) and side elements (5), at least one rigidifying frame (21) comprising a front crossbeam, a rear crossbeam and two side beams; and at least one connector (70) for connecting the rigidifying frame (21) to the top and/or bottom of the subrack (3), comprising at least one movable block movable in translation relative to the rigidifying frame (21) between an insertion position, in which it is spaced away from the subrack (3) and a use position, in which it bears against the subrack (3). The connector (70) is configured for connecting the rigidifying frame (21) to the top and/or bottom of the subrack (3) such that the front and rear crossbeams each extend substantially parallel to a top or bottom rail (7, 9) of the subrack (3) and in alignment therewith along a vertical direction.

Abstract: A cable lead-through assembly (2) includes s frame (10) delimiting a cable reception space (20); and an in-frame sub-system (11) configured for securing cables (1) to the frame (10). The in-frame sub-system (11) includes at least two plates (32) intended for extending in said cable reception space (20), the plates (32) being configured for being coupled to the frame (10) and for forming between each other at least one cable's path for at least one cable (1); securing means (14) configured for securing the or each cable (1) to a corresponding plate (32); and a locking unit (16) coupled to the frame (10). The locking unit (16) has an at-rest configuration and an operational configuration. The locking unit (16) is configured for displacing the plates (32).

Abstract: A fan arrangement has a plurality of fans arranged in parallel to each other and configured to generate airflow along a common main flow direction. A flow channel is assigned to each fan, and a respective flow channel has a flap that can be swiveled between an open position and a closed position. The flap is constructed and positioned within the flow channel in such a way that it is supported by the airflow in the open position and brought into the closed position by a reverse flow opposing the airflow. This arrangement reliably prevents a fluidic short circuit in the event of failure of individual fans, and ensures natural draft convection in the event of failure of all fans. The flap is constructed in such a way that it is brought into the open position when no air is flowing due to its intrinsic weight.
