The ATCA Shelf provides a front replaceable air filter. The filter element is an open
cell polyurethane foam specially coated to provide improved fire retardation and
fungi resistance. It features deep loading, large dust holding capacity, low air
resistance, and complies with NEBS-GR-63-CORE.
There is a switch to detect whether an air filter is installed. This switch is exposed to
the Shelf manager as a presence sensor on the Fan Tray.
