A modular 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 frequency converter class contains various types of frequency converters. A first type of frequency converters of the frequency converter class consists of: power electronics, a carrier element, and a housing element of a first housing element type that, in connection with the carrier element, forms a housing for the power electronics, and a second type of frequency converters of the frequency converter class consists of: the power electronics, the carrier element and a housing element of a second housing element type that, in connection with the carrier element, forms a housing for the power electronics.

A technique for exchanging signals between a control system (200) and at least two field devices (300) is described. One device aspect of the technique comprises a base (102) that comprises a control interface (104) and at least two slots (106). The control interface (104) is configured to connect (108.1) to at least two electrical line channels (108) of the control system (200) and the at least two slots (106) are each configured to detachably mechanically connect (106.1) to a module (110) and to pass (106.2) at least one of the line channels (108) to the respective module (110). Furthermore, the device comprises one or more modules (110), each of which comprises a base-side slot interface (112) and a field-side input and/or output interface, I/O interface, (114) different from the slot interface (112), wherein the slot interface (112) is configured for a detachable mechanical and electrical connection to one of the slots (106) of the base (102), and the I/O interface (114) is configured for a connection (116.1) to signal lines (116) of one of the field devices (300).

Provided is an expansion card installation module including an expansion-card bracket, an operating element, a stopper, and a driving component. The operating element is pivoted on the expansion-card bracket. The stopper is slidably disposed on the expansion-card bracket and is located at a stop position or a non-stop position. The stopper at the stop position is adapted to stop an expansion card in the expansion-card bracket, and the stopper at the non-stop position releases the expansion card, such that the expansion card is allowed to be removed from the expansion-card bracket. The driving component is movably disposed on the expansion-card bracket. The operating element is adapted to push against the stopper to move the stopper from the stop position to the non-stop position, and the driving component is adapted to position the stopper at the non-stop position. A server is also provided.

The telco-grade server/Ethernet network switch is the most compacted-size design with a 1.5 U or 2 U height chassis. A high-speed backplane to connect with all boards, including server/Ethernet switch board, LAN port interface board, power supply board, management board and fan module board and hot-swappable feature supported. Two equal switches are accommodated within chassis to perform two independent switches or one switch with telco-grade to meet high reliability request, such as 99.999% reliability.

An apparatus is provided for loading an electronic device, e.g., a populated GPU board, onto a device tray, e.g., a GPU tray, where the electronic device is cumbersome and the device tray presents obstacles that prevent simply lowering the device into the tray. The apparatus includes a dolly and a base, the base configured to position the dolly against the device tray so that the dolly, carrying the board, may slide the device into position and then be removed from beneath the device.
