  title: Dell Servers Power Action with State Polling
  summary: Issue a power action on a system and poll until the power state settles.
  description: >-
    Drives a power transition on a Dell PowerEdge server through the iDRAC
    Redfish API and waits for it to complete. The workflow reads the current
    power state, issues the requested reset action, and then re-reads the
    system on a poll loop until the reported power state is no longer a
    transitional value such as PoweringOn or PoweringOff. Branching directs the
    flow back into the poll loop while the system is still transitioning and
    ends the flow once a stable state is reached. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
