The system fan module has been designed for ease of use and has support for several 
management features that can be utilized by the server board management system.   

•  The fan module houses two different fan sizes.  System fans 1, 2, 3 and 4 use an 80mm 

fan, while system fans 5 and 6 use a 60mm fan. 

•  Each fan is designed for tool-less insertion to or removal from the fan module and can 

be hot-swapped in the event of failure.  

•  Each fan within the module is equipped with a failure LED.  In the event of a fan failure, 

the failure LED on the failing fan can be illuminated by server management. 

•  Each fan within the module is capable of supporting multiple speeds. If the internal 

ambient temperature of the system exceeds the value programmed into the thermal 
sensor data record (SDR), the BMC firmware will increase the speed for all the fans 
within fan module. 

•  Each fan connector within the module supplies a tachometer signal that allows the BMC 

to monitor the status of each fan. If one of the fans should fail, the remaining fans will 
increase their rotation and attempt to maintain the thermal requirements of the system. 

To control airflow within the system, the chassis uses an air baffle and a CPU air duct to isolate 
and direct airflow to three critical zones: the power supply zone, the full height PCI riser zone, 
and the CPU/memory/low profile PCI riser zone. 

An air baffle is used to isolate the air flow of the main system board zones from the zone directly 
behind the power supply.  As the power supply fans pull pre-heated air through the power 
supply from inside the chassis, the zone behind it must remain as cool as possible by drawing 
air from the leftmost drive bays only.  

The full height riser zone is the area between the power supply assembly and the full height 
riser card of the riser assembly.  The air flow through this area is generated by system fan 3 of 
the fan module in a non-redundant fan configuration. In a redundant fan configuration, the air 
flow for this zone is provided by system fans 5 and 6. Air is drawn from the drive bay area 
through the fan and pushed out of the system through ventilation holes the back side of the 
chassis.
