accompanying 19-Inch Fan Filter Housing Assembly
(P/N 1182971L1).

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.
