Component ejection for fluid leak isolation

A sensor may detect a coolant leak at or near an appliance that is slidable between a seated position and an ejected position relative to a rack. In the seated position, a coolant supply line may be coupled with a conduit of the appliance to convey coolant past the appliance. A biaser can bias the appliance toward the ejected position, and a latch may secure the appliance in a seated position against the biaser. A releaser can release the latch in response to coolant leak detection by the sensor and permit the biaser to move the appliance toward the ejected position, for example, which may cause the conduit to become disconnected from the coolant supply line to cut off flow to the leak.
