Each fan is designed for tool-less insertion and extraction from the fan assembly
Fan speed for each fan is controlled by integrated platform management. As system thermals
fluctuate high and low, the integrated BMC firmware will increase and decrease the speeds
to specific fans within the fan assembly to regulate system thermals
Each fan has a tachometer signal that allows the integrated BMC to monitor its status
On top of each fan is an integrated fault LED. Platform management illuminates the fault LED
for the failed fan.

4.4 Power Supply Module Fans
Each installed power supply module includes embedded (non-removable) 40-mm fans. They are
responsible for airflow through the power supply module. These fans are managed by the fan
control system. Should a fan fail, the power supply will shut down.
