5.1 Replacing the Air Filter
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
Section 5.1.1,
“Removing the Air Filter” on page 5-1 . 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.
