CAUTION: Damage can occur if you attempt to install a fan module into a
chassis with a different airflow direction. Compare the router product model
with the airflow marking on the handle to ensure that you are installing a fan
module with the same airflow direction as the chassis. The fan modules are
designed so that they can only be inserted into the ACX5400 product model
that supports the same airflow type. See “Cooling System and Airflow in
ACX5448, ACX5448-D, and ACX5448-M Routers” on page 47 for more
information.
