Reversible fan module

A system, comprising:

• a reversible fan module that creates an airflow, comprising:
• a set of attachment members, disposed on a face of the reversible fan module, adapted to secure the reversible fan module in one selected from a group consisting of a first orientation and a second orientation,
• a chassis, comprising:
• a divider that divides an interior region of the chassis into a front compartment and a rear compartment,
• a window, disposed on the divider, that allows airflow between the front compartment and the rear compartment,
• a first opening in the chassis that opens the front compartment to a first external region,
• a second opening in the chassis that opens the rear compartment to a second external region,
• a bay adapted to receive the reversible fan module,
• a first power supply module, disposed in the rear compartment, adapted to be cooled by at least one selected from a group consisting of a forward airflow and a reverse air flow,
• a second power supply module, disposed in the rear compartment, adapted to be cooled by at least one selected from the group consisting of the forward airflow and the reverse air flow, and
• a set of attachment receptacles adapted to mate with the set of attachment members,
• wherein when the reversible fan module is received in the first orientation, the forward airflow is directed into the first opening, through the front compartment, into the rear compartment, through the second power supply module, through the reversible fan module, through the first power supply module, and out of the second opening,
• wherein when the reversible fan module is received in the second orientation, the reverse airflow is directed into the second opening, into the rear compartment, through the first power supply module, through the reversible fan module, through the second power supply module, into the front compartment, and out of the first opening.
