Cooling

An MPS cabinet can produce a high amount of heat. Therefore, the cabinet is equipped with special
doors and cooling fans. The front is a ventilated door, and the back door has six 6-inch fans to
remove the air from the cabinet. The fans are wired as two separate circuits, one containing two
fans and one containing four.
