The Power Off action does not disable the battery, halt the processor, or switch the SP status to
Active Secondary. Use the Prepare to Power Off action to perform these operations before using the
Power Off action.

The status of the power supply on the other PMF2 CRU in this enclosure is OK.●
The other PMF2 CRU in this enclosure has ServerNet accessibility.●
The processor in the other PMF2 CRU in this enclosure has connectivity to CPU 0 or CPU 1.●
If the checks fail, the Prepare to Power Off action fails, and the steps that follow are not taken. If the
