Power Supply and Cooling Fan Modules
The SCv3000 and SCv3020 storage system supports two hot-swappable power supply/cooling fan modules.
The cooling fans 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
significantly 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.
SCv3000 and SCv3020 Storage Controller Features and Indicators
