An example modular diagnostics interface system includes one or more insertable measurement boards configured to communicably couple with a backplane of a modular measurement rack, and configured to collect a measured current from a component of a beamline.

The disclosure provides a server including a housing, a plurality of Hash boards, a power module, a control module, a power supply module, and an electrical connection board. Each Hash board is disposed in the first accommodation cavity of the housing; the power module is disposed in the second accommodation cavity; the control module is slidably disposed in the third accommodation cavity; the power supply module is slidably disposed in the fourth accommodation cavity; the electrical connection board is disposed in the housing. The plurality of Hash boards, the power module, the control module, and the power supply module are all connected to the electrical connection board; the power module supplies power to the plurality of Hash boards via the electrical connection board, and the power supply module supplies power to the control module via the electrical connection board.

A modular networking hardware platform utilizes a combination of different types of units that are pluggable into cassette endpoints. The present disclosure enables the construction of an extremely large system, e.g., 500 Tb/s+, as well as small, standalone systems using the same hardware units. This provides flexibility to build different systems with different slot pitches. The hardware platform includes various numbers of stackable units that mate with a cost-effective, hybrid Printed Circuit Board (PCB)/Twinax backplane, that is orthogonally oriented relative to the stackable units. In an embodiment, the hardware platform supports a range of 14.4 Tb/s-800 Tb/s+ in one or more 19″ racks, providing full features Layer 3 to Layer 0 support, i.e., protocol support for both a transit core router and full feature edge router including Layer 2/Layer 3 Virtual Private Networks (VPNs), Dense Wave Division Multiplexed (DWDM) optics, and the like.

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
