Abstract: A server power supply includes a first voltage input line, a second voltage input line, a ground cable, a switch, and a voltage limiting device. The switch and the voltage limiting device are connected in series and located between the first voltage input line and the ground cable. When a voltage of the first voltage input line is greater than a conduction voltage, both the switch and the voltage limiting device are in an ON state, so that the server is protected from a relatively high voltage. When the voltage of the first voltage input line decreases and is less than the conduction voltage after the voltage of the first voltage input line is greater than the conduction voltage, the voltage limiting device is in an OFF state.

Abstract: A computing system includes a plurality of fusion nodes and a plurality of switching nodes. A first fusion node in the plurality of fusion nodes includes a plurality of computing chips and at least one first switching chip. The at least one first switching chip is configured to implement communication connection between the plurality of computing chips. A first switching node in the plurality of switching nodes is coupled to the first fusion node through a connector. The first switching node is configured to implement communication connection between the first fusion node and another fusion node in the plurality of fusion nodes. The switching chip and the computing chips are deployed nearby. A mode of orthogonal connection and two-level data exchange is used between the plurality of fusion nodes and the plurality of switching nodes, to build a high-density system with high performance, a high bandwidth, and low latency.
