®
19-Inch Fan Filter
(P/N 1182970L1), illustrated in
accompanying 19-Inch Fan Filter Housing Assembly
(P/N 1182971L1).
Revision History
This is the second issue of this practice. This issue
includes a maintenance note concerning filter
replacement.
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.
3. INSTALLATION
NOTE
This product is intended to be used with the
Total Access 19-Inch Heat Baffle and Fiber
tray only.
