Abstract
A method provides a service mode within a direct-injection liquid-cooled (DL) Rack Information Handling System (RIHS) having at least one liquid-cooled (LC) node. The method includes: in response to detecting selection of the service mode trigger, transmitting a first control signal to cause a proportional valve to move to an open position for enhanced cooling of the node; monitoring a temperature being sensed in the node; and in response to the temperature reaching a pre-established service mode temperature: forwarding a second control signal, to cause the proportional valve to move to a fully closed position; and generating a notification of an entry of the RIHS into a service mode during which an LC node can be re-engaged with the supply and return port, without affecting an operational on-state of the RIHS and without incurring significant hydraulic pressure when re-engaging the LC node with the liquid cooling system.
