Abstract
A reversible fan tray device is provided for a power supply unit. The fan tray device includes a mounting panel to be removably mounted to the power supply, a fan unit secured to the mounting panel to provide airflow through the electronic device, and an interconnection board secured to the mounting panel to provide an electrical connection between the fan unit and the power supply unit. The mounting panel can be positioned in either of two orientations, the first orientation to draw external air into the power supply unit and the second orientation to force internal air out of the power supply unit. The interconnection board mates with a connector on the power supply unit when the fan tray cassette is in either of the two orientations. The interconnection board provides an airflow direction indication to the power supply unit for an existing orientation of the two orientations.
