4.6.1.2 Air Filter
The OLT system has a single air filter located at the left side of the chassis.
Filter maintenance is dependent on the environmental air quality in which the system is installed.
The filter should be checked, at a minimum, annually (8760 hours) 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 Removing 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.
