Power Supply or 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.

NOTE: If you remove a fully functioning power supply/cooling fan module, the fan speed in the remaining module increases
