8.4.10 PowerCycleStateMachineType ToC Previous Next index

The PowerCycleStateMachineType is 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 NotWaitingForPowerCycle automatically.

There are no methods, all transitions originate from the installation process. The state machine is illustrated in Figure 51 and formally defined in Table 80. The transitions are formally defined in Table 82.
