Replacing Cooling Fan Modules
The SC180 expansion enclosure supports five cooling fan modules. If one cooling fan module fails, the
remaining cooling fan modules continue to cool the expansion enclosure.
NOTE: When a cooling fan module fails, the cooling fan speed in the remaining modules increases
significantly to provide adequate cooling. The cooling fan speed decreases gradually when a new
cooling fan module is installed.
