Abstract: A system including multiple power supplies is provided. Each of the power supplies is configured to provide a standby power to a management unit in the system through a standby output and a main power through a main output, when an input power signal has been received for the system. The system also includes a resistor configured to receive a standby signal from each of the power supplies to raise a signal voltage, wherein the standby signal is a pre-selected current. The system also includes a controller in each of the power supplies, the controller configured to raise the signal voltage to the specified value when the signal voltage is greater than a threshold, and to enable the standby power from a respective power supply to reach the management unit when the signal voltage is within the specified value. A method to use the above system for a synchronized power supply to a management unit is also provided.

Abstract: One example of a device includes a low voltage direct current (LVDC) bus and a high voltage direct current (HVDC) to LVDC converter to receive HVDC power from an enclosure and provide main LVDC power. The device includes a circuit to pass the main LVDC power to the LVDC bus while the main LVDC power is within regulation limits and to pass backup LVDC power from the enclosure to the LVDC bus in response to the main LVDC power falling outside the regulation limits.

Abstract: Example implementations relate to backup power communication. For example, a system for backup power communication can include a shared backup power supply coupled to a node, a plurality of loads supported by the node, and a pass-through device to support multi-master communication between the shared backup power supply and the plurality of loads.

Abstract: Examples herein relate to a power supply system for a server. The system comprises a primary source, a power interface and a direct current (DC) energy supply chargeable by the primary source through the power interface. The primary source to power the server through the power interface and in the event of failure of the primary source, the DC energy supply powers the server through the power interface. The DC energy supply is located inside the server on a cool side of the server.

Abstract: Example implementations relate to determining computing device information. In some examples, a controller may comprise a processing resource and a memory resource storing machine-readable instructions to request a handshake signal from a power supply of a computing device, receive a response signal from the power supply that includes modified power factor correction characteristics in response to the handshake signal request, and determine, based on the modified power factor correction characteristics, information about the computing device.

Abstract: Example implementations relate to server node shutdown. For example, a server node shutdown can include detecting a secondary power supply integrated into a server node, receiving a primary power supply interruption signal from the secondary power supply, and initiating a sequenced shutdown of the server node in response to receiving the signal using the secondary power supply.
