A system circuit board configured to be supplied by at least one power supply unit, with an operating voltage in an operating state and a stand-by voltage in at least one stand-by state, the system circuit board includes at least one connection device for at least one extension card, wherein the connection device is configured to provide at least one first card voltage on the basis of the operating voltage; at least one switching element arranged on the system circuit board and configured to disconnect the at least one connection device from the operating voltage; and a control device arranged on the system circuit board, and configured to identify a type of a connected power supply unit and send a switching signal to the switching element depending on the identified type.

System circuit board, operating method for a system circuit board, and computer system

An interface arrangement () includes a plug connector () arranged on an interface board (). Furthermore, the interface arrangement () includes an electrically conductive cover () at least partially surrounding the plug connector (). The electrically conductive cover () is adapted to seal an interface opening of the housing, in which opening the plug connector () can be arranged, against electromagnetic radiation. The electrically conductive cover () includes at least one tab () with a latching device. The interface board () includes at least one receiving device, which is adapted to receive the at least one tab () and to latch with the latching device. A computer system with such an interface arrangement (), and a method for assembling such an interface arrangement ().

Interface arrangement with protection against electromagnetic radiation and computer system using a method of assembling the same

A computer system that includes a power supply unit that generates at least one secondary supply voltage (V) and an auxiliary voltage (V) based on an AC supply voltage (V), and a system board electrically connected to the power supply unit, the system board comprising a sequencing microcontroller that selectively activates further components of the system board, the further components comprising a chipset, wherein the sequencing microcontroller is configured to monitor the state of at least one control signal of the power supply unit and/or the system board to detect a failure of the AC supply voltage (V) and signal the failure of the AC supply voltage (V) to at least the chipset.
