Power Supply Fans
The fans in the power supply module are used for cooling the power supply module itself while system-level
cooling is provided by fans within the chassis. The power supplies do not depend on the system-level fans
for cooling. Fan failure is determined by fan-rotation sensors.
The fans in the power supply modules will run as soon as the power supply is plugged in, even if the power
switch is in the Standby position.
