2. DESCRIPTION
The Fan Filter and Fan Filter Housing Assembly 
function together to filter air drawn from outside the 
shelf by the 19-Inch Fan Assembly (P/N 1182006L1).  
The Fan Assembly draws air through the Total Access 
shelf to cool the modules and vent heat through the rear 
of the Heat Baffle and Fiber Tray. The Fan Filter and 
Fan Filter Housing Assembly prevent dust and debris 
from collecting on the modules and PCB components, 
minimizing potential module performance degradation.

This product is intended to be used with the
Total Access 19-Inch Heat Baffle and Fiber
tray only.

After unpacking the unit, inspect it for damage. If 
damage is found, file a claim with the carrier, then 
contact ADTRAN Customer Service. (Refer to the 
Warranty and Customer Service section of this 
practice.)
