Installing the Baffle
Purpose: Redirect air coming into, and objects falling down toward, the FTTN shelf. Follow the steps in
the table below to attach a baffle above the FTTN shelves for all CO or customer premise applications.
The baffle has two purposes: 1) redirect air toward the back isle so that components located below the
FTTN shelves will not over heat, and 2) Keep objects from falling into the FTTN shelf. The baffle can
either be fixed at a height above the Fan Shelf to allow for three CPS3200U Shelves or be removed and
reattached every time a CPS3200U shelf is added.
Note: There are two to airflow options provided for different applications: Airflow direction optimized
for CO deployments provided by the FTTN fan shelf is downward. Airflow direction for OSP
applications is bottom to top. Baffles should be oriented to direct cold air from the aisle through the
converter shelf and out the back of the rack. A filter is available and should be utilized in high
contaminant areas with proper filter maintenance.
