Abstract
Systems and methods are provided for cooling an electronics rack, which includes a heat-generating electronics subsystem across which air flows from an air inlet to an air outlet side of the rack. First and second modular cooling units (MCUs) are associated with the rack and configured to provide system coolant to the electronics subsystem for cooling thereof. System coolant supply and return manifolds are in fluid communication with the MCUs for facilitating providing of system coolant to the electronics subsystem, and to an air-to-liquid heat exchanger associated with the rack for cooling air passing through the rack. A controller monitors the system coolant and automatically shuts off flow of system coolant through the heat exchanger, using at least one isolation valve, upon detection of failure at one of the MCUs, while allowing the remaining operational MCU to provide system coolant to the electronics subsystem for liquid cooling thereof.
