Management: Installing Array Components 257
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.
