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. Each module contains two separate cooling fans. 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 replacing the modules, see
"Power Supply/Cooling Fan Module" on page 204.
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.
