The PowerCycleStateMachineTypeis used to inform the user to perform a manual power cycle.

When the server needs a manual power cycle it indicates that to the client by changing the state to WaitingForPowerCycle. After restart of the Device,it transitions to NotWaitingForPowerCycleautomatically.

There are no methods, all transitions originate from the installation process. The state machine is illustrated in Figure 51and formally defined in Table 95. The transitions are formally defined in Table 97.
