The system tray includes a fan assembly consisting of three managed 40x40x48 mm dual-
rotor, multi-speed fans. Three fans are using the same 8-pin fan connectors. 

They provide the primary cooling for the processors, memory, and the hard drive bays on the 
front panel. Each fan is designed for tool-less insertion to or removal from the fan module 
housing.  

The system fan module is designed for ease of use and supports several management 
features that the server board management system can use. 

Note: The fans are NOT hot-swappable. You must turn off the system to replace a failed fan. 

Each fan within the module is capable of supporting multiple speeds. Fan speed changes 
automatically when internal ambient temperature of the system or processor temperature 
changes. The fan speed control algorithm is programmed into the server board’s BIOS. 

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 system fault LED on front 
panel will light.  

Note: There is a spare fan kit that contains six system cooling fans. 

The fan connector pin-out definition is in chapter 2.7.1.7.  

Each power supply module supports one non-redundant 40 mm fan. The fans control the 
cooling of the power supply and some drive bays. These fans are not replaceable. 
Therefore, if a power supply fan fails, you must replace the whole power supply unit.

 

 

Each tray in the chassis requires the use of an air duct module to direct airflow over critical 
areas within the system. The following provides a summary and description of Air Duct 
Module.
