Apparatus, system, and method for fault tolerant cooling in a redundant power system

An apparatus for fault tolerant cooling in a redundant power system, the apparatus comprising:

• a receiving module that receives power from a common power bus to power one or more power supply fans, the common power bus receiving power from two or more redundant power supplies, the common power bus powering at least an electronic load and the one or more power supply fans wherein each of the one or more power supply fans cools at least a redundant power supply in which the power supply fan resides and components within an electronic device, the components comprising the electronic load;
• a detection module that detects a non-functioning redundant power supply;
• a signal module that receives a fan control signal within a non-functioning redundant power supply;
• and
• a synchronization module that uses the received fan control signal to synchronize a fan speed of one or more power supply fans within the non-functioning redundant power supply, the fan speed synchronized with at least one fan control signal of a power supply fan within a functioning redundant power supply.

A system for fault tolerant cooling in a redundant power system, the system comprising:

• an electronic device comprising one or more components, the components comprising an electronic load;
• a common power bus that receives power from two or more redundant power supplies, the common power bus powering at least an electronic load and one or more power supply fans;
• two or more redundant power supplies that receive input voltage from a power source and provide a regulated output voltage to the common power bus, each redundant power supply comprising one or more power supply fans, each redundant power supply comprising:
• a receiving module that receives power from the common power bus to power one or more power supply fans wherein each of the one or more power supply fans cools at least a redundant power supply in which the power supply fan resides and components within the electronic device;
• a detection module that detects a non-functioning redundant power supply;
• a signal module that receives a fan control signal within a non-functioning redundant power supply;
• and
• a synchronization module that uses the received fan control signal to synchronize a fan speed of one or more power supply fans within the non-functioning redundant power supply, the fan speed synchronized with at least one fan control signal of a power supply fan within a functioning redundant power supply.
