Cooling Fans

Your system supports up to six cooling fans. For a system with only one processor, a dummy fan is pre-installed on the
sixth cooling fan slot (FAN6). You must remove the dummy fan and install a cooling fan in the FAN6 slot when you install
a second processor.
NOTE: In the event of a problem with a particular fan, the fan number is referenced by the system's management
software, allowing you to easily identify and replace the proper fan by noting the fan numbers.

Removing A Cooling Fan

WARNING: Opening or removing the system cover when the system is on may expose you to a risk of electric
shock. Exercise utmost care while removing or installing cooling fans.
