29. An apparatus, comprising:
-
a first power supply module connected with a first side of a midplane board, wherein the first power supply module comprises a first reversible fan; and
a second power supply module connected with a second side of the midplane board, wherein the second power supply module comprises a second reversible fan;
wherein upon determination that the first power supply module is on the first side of the midplane board, the first reversible fan spins in a clockwise direction;
wherein upon determination that the second supply is on the second side of the midplane board, the second reversible fan spins in a counterclockwise direction to move air in a same direction as the first reversible fan. - View Dependent Claims (30, 31, 32)

33. A method, comprising the steps of:
-
determining whether an electronic module is communicatively coupled in a first position or a second position, wherein the electronic module comprises a reversible fan; and
setting a rotation direction of the reversible fan based on whether the electronic module is in the first position or the second position. - View Dependent Claims (34, 35, 36, 37, 38, 39)

40. An apparatus, comprising:
-
means for receiving an electronic module on a first side of a midplane board and a second electronic module on a second side of the midplane board, wherein the first electronic module comprises a first fan and the second electronic module comprises a second fan, wherein a rotational direction of the second fan is reversible; and
means for setting the rotational direction of the second fan to be opposite a rotational direction of the first fan so airflow through the second fan is in a same direction as airflow through the first fan. - View Dependent Claims (41, 42, 43)
