The cooling system in ACX5000 routers consists of fan modules and a single fan in each power supply.
The number of fan modules vary depending whether the size of the router is 1 U or 2 U high. All routers
can be set up to work in the following airflow direction:
•
Airflow Out (AFO)—Air comes into the router through the vents in the front panel.

Fan Modules
The fan modules in ACX5000 routers are hot-insertable and hot-removable field-replaceable units (FRUs).
These fan modules are designed for air to enter from the ports to the FRU–Airflow Out. The fan modules
are installed in the fan module slots on the management panel of the router next to the power supplies.
