    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. After the initial period of time passes, the power provided to the computing system by the battery backup unit is reduced at a particular rate of change while the power from the backup generator system is allowed to flow to the computing system through the power supply unit.

    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: Various embodiments of the present technology provide systems and methods to pair each of a plurality power supply units (PSUs) of a server system with a corresponding one of a plurality of ATS modules. A failed ATS module or PSU can be detected and replaced without forcing a shutdown of the remaining pairs of PSUs and ATS modules of the server system. In some embodiments, a controller of the server system can monitor status of each of the plurality ATS modules and the plurality of PSUs. Based at least in part upon statuses of the plurality ATS modules and the plurality of PSUs, the controller may further determine an optimized output power of the PSUs and manage loading of the server system.

    Abstract: Various examples of the present disclosure provide a high efficient battery backup (BBU) system and systems and methods for managing the BBU system through a microcontroller unit (MCU) and an ORing FET system of the BBU system. In some examples, a baseboard management controller (BMC) of a server system is used to control the MCU and the ORing FET system of the BBU system such that the BBU system can operate in multiple operating modes without a battery discharger. The operating modes of the BBU system includes, but are not limited to, a battery constant-current-charging mode, a battery constant-voltage-charging mode, a battery discharging mode, or a battery capacity calibration mode.

    Abstract: Various embodiments of the present technology provide methods for determining a status of power supplies to a server system and dynamically managing an uninterruptible power system (UPS) of the server system between an off-line mode and an on-line mode based upon the status of the power supplies. The UPS requires a minimum standby power during the off-line mode while requires no switch time to continuously supply power to loads of the server system during the on-line mode. Some embodiments determine a status of an AC input power to a server system and, in response to detecting an abnormal condition associated with the AC input power, generate a power warning signal. The power warning signal can cause an UPS of the server system to be switched from an off-line mode to an on-line mode.
