Server filter maintenance is dependent on the environmental air quality in which the server is installed. The filter should be checked, at a minimum, annually and cleaned or replaced if there is evidence of airflow blockage. In environments with high particulate matter, the filter should be checked, cleaned or replaced more often. Should the filter require cleaning, remove the filter from the server. See Remove the Air Filter. Take the filter to an open area and blow the particles from the filter using a can of compressed air. Do not use a coarse brush or anything abrasive since they may damage the filter.
Before You Begin
Caution - Do not open the bezel when the server is on a flat surface. Open the bezel while the server is installed in a rack or the front of the server (including the bezel) is hanging over the edge of a flat surface.

Note - Do not operate the server without an air filter.
