Claim of US Patent No. 10,143,114

1. A Rack Information Handling System (RIHS) comprising:a rack having chassis-receiving bays;
a liquid cooling subsystem that provides cooling liquid to one or more liquid cooled (LC) nodes received in the chassis-receiving bays;
one or more leak collection structures positioned to receive cooling liquid that leaks from the liquid cooling subsystem;
one or more liquid sensors that detects a presence of leaked cooling liquid in any of the one or more leak collection structures, wherein the one or more liquid sensors include a node-level liquid sensor that detects leaks within a respective LC node; and
a leak detection subsystem communicatively coupled to the one or more liquid sensors and which responds to a detected presence of liquid by providing a leak indication.
