Power Supply and Cooling Fan Modules
The SCv3000 and SCv3020 storage system supports two hot-swappable power supply/cooling fan modules.
The cooling fans that cool the storage system and the power supplies are integrated into the power supply/cooling fan module and cannot
be replaced separately. If one power supply/cooling fan module fails, the second module continues to provide power to the storage system.
NOTE: When a power supply/cooling fan module fails, the cooling fan speed in the remaining module increases signicantly to
provide adequate cooling. The cooling fan speed decreases gradually when a new power supply/cooling fan module is installed.
CAUTION: A single power supply/cooling fan module can be removed from a powered-on storage system for no more than 90
seconds. If a power supply/cooling fan module is removed for longer than 90 seconds, the storage system might shut down
automatically to prevent damage.
