Abstract

According to one embodiment, a leak segregation system for a rack that includes a rack liquid manifold. The system includes at least one leak segregation structure that is mounted to the manifold, the structure having a top opening, a bottom that includes at least one opening, a back opening for receiving a manifold connector of the manifold, and a front opening for receiving a connector of an electronics component mounted within the rack, where the structure contains the manifold connector and at least partially contains the connector when the connectors are coupled together. The system also includes a leak detection structure that is positioned below the leak segregation structure and includes a leak detection sensor that is configured to detect a presence of liquid from the leak segregation structure.
