Abstract: The present disclosure provides a system and method for dynamically defining a specific input pin of a management controller (e.g., a baseboard management controller (BMC)) of a server system in response to a new device being plugged into the server system. The new device comprises one of a power supply unit (PSU), an automatic transfer switch (ATS), or a battery backup unit (BBU) of the server system. In some implementations, the PSU, the ATS, and the BBU are modularized into a plurality of ATS modules, a plurality of PSU modules, and a plurality of BBU modules, respectively. Each of the plurality of ATS modules, the plurality of PSU modules, and the plurality of BBU modules has substantially the same physical size.

Abstract: A system and method is directed to charging and discharging an energy-tank capacitor of a power supply unit (PSU) in a computing system. The PSU has a forward converter, a buck converter, a switch box, and an option box. The forward converter has a transformer. A primary winding of the transformer is coupled to an input of the PSU, while a secondary winding of the transformer is coupled to an output of the PSU. Two or more components of the forward converter are shared with the buck converter to support the functionality of the buck converter when it is enabled. The switch box has a power switch and a controller switch connected to the forward converter. The energy stored on the energy-tank capacitor is capable of supporting power consumption of the server system during a hold-up time, when an input power to the PSU is interrupted.

Abstract: In some implementations, power provided to a computing system, such as a rack system, may be interrupted. This interruption is detected, and in response, power from a battery backup system is directed to the computing system to replace the interrupted power source, which in some implementations may be a main AC power grid source. A signal is received indicating that a backup power source, for example a backup generator system, is online and prepared to deliver power to the computing system. For an initial period of time, this backup power source is prevented from providing power to the computing system. For example, the backup generator system may be providing power to a power supply unit of the computing system, but the power is not allowed to flow to the computing system.
