Left-to-right cooling
Airflow moves from left to right to cool the Control Processor and interface modules. Two
9012FC cooling modules, located on the front right side of the 9012 chassis, provide this air
movement and have adjustable fan speed that depends on the system temperature.

Each 9012FC cooling module has eight fans. The platform polls all line card and CP card
sensors and adjusts the 9012FC fan speed accordingly.
