Avaya 9012FC IO Manual page 31

Each 9012FC cooling module or 9012FCHS cooling module has eight fans. The platform polls all
I/O module and CP module sensors, and adjusts the 9012 fan speed accordingly.
Front-to-back cooling
Airflow moves from front-to-back to cool the Switch Fabric and auxiliary modules. Two 9012RC
cooling modules, at the top back of the Virtual Services Platform 9012, provide the air movement
and have adjustable fan speed that depends on system temperature.
Figure 8: 9012RC cooling module
In the Virtual Services Platform 9012, two fans exist in each 9012RC cooling module and pull air
from front-to-back. The platform polls all Switch Fabric module sensors and adjusts the 9012RC fan
speed accordingly.
Note:
Do not place the Virtual Services Platform 9012 directly against a wall, equipment, or other
obstruction. Avaya recommends 36 inches (91 centimeters) of free space in both the front and
back of the machine, and 6 inches (15.2 centimeters) on each side extra. Depending on the
circumstances, increase the free space at the side to allow for more airflow or cool airflow into
the Virtual Services Platform 9012.
