Methods, systems, and computer programs encoded on computer storage medium, for identifying a power event of a chassis system; in response to identifying the power event, negotiating between a first and a second enclosure controller (EC) to place the one of the ECs in an active state, wherein the first and the second EC are redundant; in response to placing one of the ECs in the active state, performing, by a chassis orchestration engine, a sequence of actions, including: determining, by coordinating with a first daemon, whether a condition is present that would prevent safe activation of a power supply unit, activating, by coordinating with a second daemon, the power supply unit of the chassis system, activating, by coordinating with a third daemon, a cooling system of the chassis system after performing the sequence of actions, providing a signal to components indicating the active state of the first EC.
