3.1 Non-redundant Fan Module

This option provides the primary airflow for system configurations that do not require redundant
cooling.

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 and 2 use an 80mm fan,
while system fan 3 uses a 60mm fan.
• Each fan is designed for tool-less insertion to or removal from the fan module housing.
Note: The fans are NOT hot-swappable. The system must be turned off in order to
replace a failed fan.
• 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 the 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.
