First Claim
Patent Images
1. A system, comprising:
- a first reversible power supply fan of a first power supply module that rotates in a clockwise direction if the first power supply module is communicatively coupled into a first position in the system and a counterclockwise direction if the first power supply module is communicatively coupled into a second position in the system;
a midplane board; and
a second reversible power supply fan of a second power supply module;
wherein the first power supply module is communicatively coupled with the midplane board in the first position, wherein the second power supply module is communicatively coupled with the midplane board in the second position.

14. An apparatus, comprising:
-
a fan controller that drives a reversible fan of an electronic module in a clockwise direction if the electronic module is communicatively coupled in a first position and a counterclockwise direction if the electronic module is communicatively coupled in a second position; wherein the electronic module is communicatively coupled with a midplane board in the first position or the second position; wherein the first position is located on a first side of the midplane board, wherein the second position is located on a second side of the midplane board; wherein a first end portion of the electronic module connects with either a first face of the midplane board in the first position or a second face of the midplane board in the second position; wherein the fan controller determines whether the electronic module is connected to the first face or the second face of the midplane board to determine whether to drive the reversible fan in the clockwise direction or the counterclockwise direction. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. 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 (25, 26, 27)

28. A method, comprising the steps of:
-
determining whether a first power supply module is communicatively coupled in a first position or a second position, wherein the first power supply module comprises a first reversible power supply fan; setting a rotation direction of the first reversible power supply fan based on whether the first power supply module is in the first position or the second position, wherein a second power supply module is communicatively coupled in either the first or second position, wherein the second power supply module comprises a second reversible power supply fan; and driving the first and second reversible power supply fans in opposite rotation directions so the first and second reversible power supply fans generate airflow in a same direction. - View Dependent Claims (29, 30, 31, 32, 33)

34. An apparatus, comprising:
-
means for receiving a first power supply module on a first side of a midplane board and a second power supply module on a second side of the midplane board, wherein the first power supply module comprises a first fan and the second power supply module comprises a second fan, wherein a rotational direction of the second fan is reversible; means for determining whether the second power supply module is communicatively coupled with the first side or the second side of the midplane board; and means for setting the rotational direction of the second fan to be opposite a rotational direction of the first fan to drive the second fan either in a clockwise direction or a counterclockwise direction based on whether the second power supply module is communicatively coupled with the first side or the second side of the midplane board so airflow through the second fan is in a same direction as airflow through the first fan. - View Dependent Claims (35, 36)
