Power Supply and Cooling Fan Features

The MD3400 and MD3420 Series storage array includes two integrated, hot-swappable power supply/
cooling fan modules. Both modules must be installed to ensure proper cooling. The system requires at
least one of the cooling fans to function, to avoid overheating.
A power supply/cooling fan module can be replaced without powering down the system. For information
on removing and installing the modules, see
