1. GENERAL

19-Inch Fan Filter
Section 61182970L1-5B
Issue 2, May 2003

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.

NOTE
NOTE
The fans must be turned off prior to Fan Filter removal to prevent dust from entering the sys­tem 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 illustra­tion of air flow through the Total Access system.
When replacing the Fan Filter, it is not neces­sary to order a complete Fan Filter Housing Assembly. A single replacement filter can be ordered using part number 1182970L1.
ADTRAN cautions against performing major repairs in the field. Repair services are available if damaged units are returned to ADTRAN. (Refer to the Warranty and Customer Service section of this practice.)
