Power Supply/Cooling Fan Module

NOTE: Your storage array includes two integrated, hot-swappable power supply/cooling fan
modules.
The array supports two hot-swappable power supply/cooling fan modules. While the array can operate
temporarily with one module, both the modules must be present for proper system cooling.
CAUTION: A single power supply/cooling fan module can be removed from a powered-on array
for a maximum period of 5 minutes. Beyond that time, the array may automatically shut down to
prevent damage.
