Airflow

MTS LiTE:
The card cage has a clear opening in the bottom front and small holes in the side and back. Ambient
airflow enters at the bottom of the front, back and sides and passes up through the modules. The
optimal solution is to allow the air inlet from all sides. At the top of the card cage there is enough space
for the air to distribute and spread before passing out of the venting grill at the top. If there is nothing in
close area to sides, the air can also exit here. The airflow routing is the same with or without fans.

The 2 BR card cage has a clear opening in the bottom front and small holes in the side and back.
Ambient airflow enters at the bottom of the front, back and sides and passes up through the modules.
The optimal solution is to allow the air inlet from all sides. At the top of the card cage there is enough
space for the air to distribute and spread. It then passes up through the filter section and out of the
venting grill at the top. If there is nothing in close area to sides, the air can also exit here. The airflow
routing is the same with or without fans.
