SPECIAL INSTRUCTIONS:
When replacing a fan, it is important to know, how to distinguish between a CPU/front fan and a Rear fan (blower).

The CPU fans will be reported as FT0/FMx (x= 0,1,2) and the rear fan (blower) reported as FT2 (in prtdiag, showenvironment and ALOM logs).

- Output from "sc> showenvironment"

Fans Status:
