Claim 5:
6. The server chassis of claim 2, wherein the plurality of return lines comprise a main return line and a backup return line, the first bidirectional connector being connected to the backup return line, the second bidirectional connector being connected to the main return line, a first connector being closed sealing the first bidirectional connector from the cooling module, a fourth connector being closed sealing the second bidirectional connector from the main return line, a second connector being open to fluidly connect the first bidirectional connector to the backup return line, a third connector being open to fluidly connect the second bidirectional connector to the cooling module, and the side gate to be in the first position, thereby returning the cooling liquid carrying the heat back from the cooling module to a rack fluid unit via the backup return line when the main return line is disconnected from the second bidirectional connector, and wherein a blocked main return line becomes unblocked, the fourth connector being configured to open to fluidly connect the second bidirectional connector to the main return line, the side gate configured to move to the second position to seal the second bidirectional connector from the first bidirectional connector, thereby returning the cooling liquid carrying the heat back from the cooling module to the rack fluid unit via the second bidirectional connector and the main return line.
