When the server switches between the two power supplies, if the server does not restart, break down, or
generate any alarm (except power failure alarms), the power supply switchover meets the requirements.
For the diagrams and tables, see the initial configuration parameter manual for the solution in use.
Save parameters before power-off.
Power off the devices in the normal power-off logic sequence.
During the power-off process, there is no fire or other exceptions, but the extinguishant
control panel displays a power failure alarm. Ignore the alarm.
After power-off, all circuit breakers should be OFF.
Shut down servers and storage devices.
Shut down cooling products.
Switch off circuit breakers level by level to power off devices by referring to the power
supply and distribution system diagram.
Switch off the external input power circuit breaker of the FusionModule1000.
