Abstract: A server cabinet includes a left side wall panel, a right side wall panel, a rear side wall panel and at least one mounting plate. Each of the mounting plates is connected to the left side wall panel and the right side wall panel, and is configured to mount an external server node. A position limiting mechanism is provided on the rear side wall panel, and is configured to limit a relative position between the mounting plate and the external server node mounted on this mounting plate.

Abstract: A power supply management circuit and method are provided. The circuit includes: a power-supplying copper bar configured to receive a power-supplying voltage from an external power supply; at least two power-supplying terminals configured to output the power-supplying voltage of the power-supplying copper bar to a hot plugging unit; the hot plugging unit connected to the at least two power-supplying terminals and a pin interface and configured to receive the power-supplying voltage outputted from the power-supplying terminals, detect whether node overcurrent occurs currently, disconnect from the at least two power-supplying terminals if node overcurrent occurs currently, and output the power-supplying voltage via a first interface in the pin interface if no overcurrent occurs currently; and a PCIE strip configured to output a signal via a second interface in the pin interface.

Abstract: A power supply copper busbar and a server are provided. The power supply copper busbar includes an upper copper busbar and a lower copper busbar, each of which includes a screwing mechanism, and at least two connecting terminals. The screwing mechanism is configured to connect an external power supply module in a screwing manner. A first connecting terminal of the at least two connecting terminals has a first shape for connecting an external node, and the connection is achieved by providing the external node with a first connecting portion having a shape corresponding to the first shape. A second connecting terminal of the at least two connecting terminals has a second shape for connecting an external fan control unit, and the connection is achieved by providing the external fan control unit with a second connecting portion having a shape corresponding to the second shape.
