The enclosed fan is located inside the chassis and cools the system. An arrow on the enclosed
fan indicates what direction air flows out.
When you install the enclosed fan, you make sure that it is facing the correct direction, so that
air blows out of the imagePASS. Failure to do so may result in future damage to the
imagePASS
