4.3 System Fans
Six managed dual rotor 40mm x 56mm system fans and an embedded fan for each installed power supply,
provide the primary airflow for the system. The following table provides the volumetric air flow requirements for
different 2U system configurations.

The system is designed for fan redundancy when configured with two power supply modules. Should a single
fan fail (system fan or power supply fan), platform management will adjust air flow of the remaining fans and
manage other platform features to maintain system thermals. Fan redundancy is lost if more than one fan is in
a failed state.
