Routine management on Huawei flash storage systems involves power-on and power-off. Which of the following statements is false about power-on and power-off? The *HCIP-Storage V5.5 Training Material (Module 5: Storage System Maintenance and Troubleshooting)* covers power management: - Option A: True. ''Correct expansion cable connections are required before power-on to ensure proper operation.'' - Option B: True. ''The BMC system allows powering on controller enclosures via the external management IP when none are powered on.'' - Option C: False. ''After an emergency power-off, the storage system is powered on via DeviceManager, CLI, or BMC, not by pressing the controller enclosure's power button, which is used for normal power-on.'' - Option D: True. ''In OceanStor Dorado 8000, powering on a controller enclosure automatically powers on cascaded disk enclosures.'' Thus, option C is false.

A. Before powering on the storage system, you need to ensure that all expansion cables are correctly connected
B. If none of the controller enclosures in the cluster are powered on, you can log in to the BMC system using the external management IP address of the BMC and run the power-on command to power on all the controller enclosures
C. To power on the storage system after an emergency power-off, you need to press the power button on the controller enclosure
D. For Huawei OceanStor Dorado 8000 storage, after a controller enclosure is powered on, its cascaded disk enclosures will be automatically powered on
