The RLS and the tape drives are cooled by outside air that is drawn into the RLS en-
closure through an air filter attached to the front of each storage matrix. This filter
keeps dust and dirt from entering the enclosure, as its presence could degrade the re-
liability 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 pe-
riodically check the air filter(s) and replace it when it becomes dirty.
Visually inspect the air filter element in the front of each storage matrix (Figure
1.
7-26 and Figure 7-27).
New air filters in RLS-85XX libraries are green and the filters in RLS-8350
2.
models are black. A color change indicates the presence of some dirt, which is ac-
ceptable. However, if dirt is clinging to the outside filter surface, it is time to re-
place the filter.
