Use underfloor air conditioning to cool the SPARC Enterprise M9000 Server (with an extended cabinet).

To use underfloor air conditioning, air-conditioning openings must be provided on the free-access floor under the cabinet. Provide appropriate floor openings by considering the air conditioning capacities required for the cabinet, the floor strength, and the locations of the leveling feet.
