7.23.1 Air Filter Inspection
The RLS and the Tape Drives are cooled by outside air that is drawn into the RLS en-
closure through an Air Filter. This filter keeps dust and dirt from entering the enclo-
sure, as its presence could degrade the reliability of the Tape Drives and media. If the
filter becomes clogged with dust and dirt, the amount of airflow will be diminished.
Diminished airflow could cause the Tape Drives to run hotter, again degrading their
reliability. Therefore, it is important to periodically check the Air Filter and replace it
when it becomes dirty.
The time between filter changes is very dependent upon the local environment. In-
spect the filter frequently when the RLS is first installed. Then, when the effects of
the local environment become known, adjust the inspection schedule accordingly.
