System Cooling Fans Do Not Rotate
Note:
In addition to the cooling fans that are an integral
part of each power supply, the system has an option board
fan and four CPU fans. The four CPU fans are redundant in
configuration. This means if one fan fails, its associated fan
changes its rotating speed to high. There are no serviceable
components inside the power supply. If the power supply is
opened, the manufacturer's warranty is voided.
