4.3 System Fans
Five 60x38-mm fans and an embedded fan for each installed power supply, provide the primary airflow for the
system. 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.
