Airflow for OS7700 Switches
1. Air Intake.
The fan tray
pulls air from the three air
intake vents located at the
bottom of the chassis.
2. Airflow.
The air from the
intake vents is directed up
through the chassis’ module
compartment and past the NI
and CMM circuit boards.
This airflow provides
required cooling for the mod-
ules and other chassis com-
ponents.
3. Air Exhaust.
The air-
flow is exhausted through
the fan tray at the rear of
the chassis.
