1. GENERAL
This practice is an installation and maintenance guide
for the ADTRAN Total Access®19-Inch Fan Filter
(P/N 1182970L1), illustrated in Figure 1 with the
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.

Installation and Maintenance Practice

261182970L1-5B
NOTE
The fans must be turned off prior to Fan Filter
removal to prevent dust from entering the sys-
tem while filters are being changed.
The Fan Filter is replaced by first removing the Fan
Filter Housing Assembly from the Heat Baffle and
Fiber Tray. Next, disassemble the housing by removing
the four phillips-head screws on the backside of the
housing and removing the rear housing panel. Discard
the old filter and install the new filter into the front
housing panel by pressing the filter down and around
the four screw holes. Replace the rear panel and mount
housing to the Heat Baffle and Fiber Tray.
The Fan Filter Housing Assembly mounts to the front of
the Heat Baffle and Fiber Tray directly beneath the
shelf. In a typical scenario, a Total Access shelf will be
mounted with a Heat Baffle and Fiber Tray above and
beneath. The Fan Assembly mounts to the rear of the
Heat Baffle and Fiber Tray above while the Fan Filter
Housing Assembly mounts to the front of the Heat
Baffle and Fiber Tray beneath. See Figure 2 for illustra-
tion of air flow through the Total Access system.
Figure 2. Total Access Air Flow
Using the two screws provided and a flat-tip screw-
driver, position and attach the Fan Filter Housing
Assembly onto the front of the Total Access Heat Baffle
and Fiber Tray. The two mounting holes are located on
the front of the Heat Baffle and Fiber Tray.
4. MAINTENANCE
The Fan Filter should be routinely replaced when it
begins to impede airflow. The life span of the filter will
vary depending upon the environment.
NOTE
When replacing the Fan Filter, it is not neces-
sary to order a complete Fan Filter Housing
Assembly. A single replacement filter can be
ordered using part number 1182970L1.
