Abstract
A fail-safe power limit (FSPL) can be applied to components that lose communication with a management module (MM) to determine a safe power level at which to operate. The FSPL may be computed by the management module (MM) for the information handling system and distributed to components in the information handling system. By computing a FSPL and transmitting the FSPL to the components, a larger amount of the available power can be used by the components. This allows the components to continue operating at performance levels closer to or equivalent to levels available when the management module (MM) is operating normally. The FSPL may be updated at set times and/or on a periodic schedule such that the FSPL used by the components when communication is lost with the management module (MM) reflects a recent operating state of the components.
