Abstract
A halt event separates a boot up operation from a run time operation. A controller grants a request from a baseboard management controller for an electrical power associated with a boot-up operation. As the baseboard management controller completes the boot-up operation (such as a power on self-test), the baseboard management controller predicts the electrical power that is required for a run time operation (e.g., executing an operating system). The baseboard management controller is then required or forced to submit a subsequent request for the additional electrical power that is required for the run time operation. The controller compares the electrical power predicted for the run time operation to a power availability from a power supply (such as a safe or maximum operating condition). If the power supply can provide the electrical power predicted to be required during the run time operation, then the controller may permit or authorize a transition from the boot up operation to the run time operation. However, if the power supply cannot provide the electrical power predicted to be required during the run time operation, then the controller denies the run time operation.
