The AMC filler boards act as an air baffle and filler panel for empty slots in MicroTCA chassis. They plug into unused slots in the chassis to redirect or contain airflow, helping to keep cool air within the critical areas of the enclosure and improving overall thermal performance. The cards also act as a filler board, preventing open slots and helping to protect the chassis from outside elements. The AMC air-baffle/filler boards come in both full and mid sizes and in single-module formats. Other sizes, including double module or compact size are available upon request.
