4.1 Introduction
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.
