Steps
1. Align the liquid cooling module with the standoff screws on the system board.
NOTE: Ensure that the liquid cooling tubes and liquid cooling leak detection cable are placed towards the rear of the
system.
2. Place the module on the processor slot and set all the anti-tilt wires to locked position (outward position).
3. Route the liquid cooling tubes on the front of the system between DIMM slots and J_SL connector.
4. Using a Torx #T30 screwdriver, tighten the captive screws (12 in-lbf).
5. The tubes leading towards the rear of the chassis and the liquid cooling leak detection cable are placed in between the PSU
2 and the clip of rear I/O board (RIO).
NOTE: Leak detection cable must be placed first into the clip (underneath the cooling tubes), then place tube 2 and
tube 1 into the clip to ensure cable does not interfere with the PCIe risers.
6. Route the rear end of the liquid cooing tubes through the RIO board.
NOTE: Follow the number labels on the liquid cooling tubes and ring holders (1,2).
7. Connect the liquid cooling leak detection cable to the connector on RIO.
8. Align the rubber ring on the tubes with the liquid cooling ring holder.
9. Tilt the liquid cooling ring holder and using a Phillips #2 screwdriver, tighten the captive screw on the liquid cooling ring
holder to secure it in place.
NOTE: The numbers on the image do not depict the exact steps. The numbers are for representation of sequence.
