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.
Note 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.
