Power Supply and Cooling Fan Features

The MD3200 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" on page 216.

CAUTION: A power supply/cooling fan module can be removed from a powered- on enclosure for a maximum period of 5 minutes. Beyond that time, the system may automatically shut down to prevent damage.
