2.7 System Fans 

 

Subdividing the SIM board area and the backplane area is a metal cage that holds the system 
fans. This server contains 12 system fans which are located inside the chassis. These system 
fans maintain the ideal temperature for the SIM boards, backplanes and disk drives. 

 

The sequence of system fans is shown below for your reference:
