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.
Removing a Power Supply/Cooling Fan Module
CAUTION: Many repairs may only be done by a certified service technician. You must only
perform troubleshooting and simple repairs as authorized in your product documentation, or as
directed by the online or telephone service and support team. Damage due to servicing that is
not authorized by Dell is not covered by your warranty. Read and follow the safety instructions
that came with the product.
NOTE: If you remove a fully functioning power supply/cooling fan module, the fan speed in the
remaining module increases significantly to provide adequate cooling. The fan speed decreases
gradually when a new power supply/cooling fan module is installed.
