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 receive a waveform corresponding to an input current that includes a non-cyclical irregular waveform modification from a power supply of a computing device, analyze the modified waveform of the input current to determine a binary message included in the modified waveform, and determine, based on the binary message, information about the computing device.

Abstract: One example of a server enclosure includes a plurality of slots, a first power backplane, and a second power backplane. Each slot includes a first power connector and a second power connector. The first power backplane is electrically coupled to each of the first power connectors. The second power backplane is electrically coupled to each of the second power connectors.

Abstract: A power converter (14) can include a switching system (18) to convert a direct current (DC) input voltage to an output voltage based on a switching signal having a duty-cycle. A controller (16) can set the duty-cycle of the switching signal, depending on the DC input voltage, to one of a substantially constant value, such that the output voltage follows the DC input voltage in a normal mode, and a value that varies inversely with respect to the DC input voltage, such that the output voltage is substantially constant in another mode.

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: Examples relate to power supply system comprising a primary power supply to deliver a first power to a load and a secondary power supply that, in response to a failure in the primary power supply, is to deliver a second power to the load. The system further comprises a primary energy storage component coupled to the primary power supply that, in response to the failure in the primary power supply, is to deliver a third power to the load while the secondary power supply transitions from a lesser output power level to a greater output power level. The third power is at the same full-rated power level than the first power.

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.
