System Fans

Three 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.

Figure 12. System Fan Identification

System Fan Assembly

The system fan assembly is designed for ease of use and supports several features.



Each fan is hot-swappable.



Each fan is designed for tool-less insertion and extraction from the fan assembly. For instructions on

installing or removing a fan module, see the

Intel

JBOD 2000 Family Service Guide



Fan speed for each fan is controlled by integrated platform management as controlled by the PDB

board. As system thermals fluctuate high and low, the PDB 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 PDB to monitor their status.



On top of each fan is an integrated fault LED, although currently this feature is not supported.



Each fan has a10-pin wire harness that connects to a matching connector on the PDB.
