Power Supply and Cooling Fan Features

The MD3800i and MD3820i 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 Power Supply/Cooling Fan Module.
