Cooling Fans

Your system contains five or six dual-rotor cooling fans housed in a fan
assembly. Single processor systems require five fans, while a sixth fan (FAN6)
is required for dual-processor systems.
NOTE:
Hot-swap removal or installation of the fans or fan assembly is not
supported.
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 on the fan assembly.
