Notes:
Up to eight fans are supported by the hardware, but not all devices will
contain eight installed fans. The number of fans depend on the cooling
requirements of the device. For fans in a '0 RPM' FAULT state, please
verify that the number of 'GOOD' labels represent the amount of installed fans.
