Prerequisites
Follow the safety guidelines listed in the Safety instructions.
Power off the system and all attached peripherals.
Disconnect the system from the electrical outlet and disconnect the peripherals.
If applicable, remove the system from the rack.
Remove the system cover.
Removing the air shroud:
Hold the edges of the air shroud, and lift the air shroud out of the system.
Removing the expansion card risers:
Loosen the captive screws on the riser and system.
Press the blue release tab or blue button on the riser and holding the edges lift the expansion card riser from the riser connector on the system board.
NOTE: The numbers on the image do not depict the exact steps. The numbers are for representation of sequence.
If the risers are not going to be replaced, install riser blanks, and if required tighten the captive screws.
NOTE: You must install a filler bracket over an empty expansion card slot to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.
WARNING: The Direct liquid cooling (DLC) module and processor are too hot to touch for some time after the system has been powered off. Allow the liquid cooling module and processor to cool down before handling them.
NOTE: Rear I/O (RIO) board is different for the system with DLC module.
Removing the Direct Liquid Cooling module:
Using a Phillips #2 screw driver, loosen the captive screw on the DLC ring holder.
Tilt the DLC ring holder to loosen the DLC tubes.
Disconnect the DLC leak detection cable from the LC RIO board.
Remove the DLC tubes from the clip and LC RIO board.
Slightly lift the DLC tubes surrounding the DIMM slots.
Ensure all four anti-tilt wires are in the locked position (outward position), and then using a Torx T30 screwdriver, loosen the captive nuts on the DLC module in the order that is mentioned below:
a. Loosen the first nut three turns.
b. Loosen the nut diagonally opposite to the nut you loosened first.
c. Repeat the procedure for the remaining two nuts.
d. Return to the first nut and loosen it completely.
NOTE: Ensure that the anti-tilt wires on the DLC module are in locked position when loosening the captive nuts.
Set the anti-tilt wires on the DLC module to the unlock position and lift the DLC module from the system.
NOTE: The numbers on the image do not depict the exact steps. The numbers are for representation of sequence.
Installing the Direct Liquid Cooling module
Align the DLC module with the standoff screws on the system board.
NOTE: Ensure that the DLC tubes and liquid cooling leak detection cable are placed towards the rear of the system.
Place the module on the processor slot and set all the anti-tilt wires to locked position (outward position).
Route the DLC tubes to the front of the system and along the DIMM latches.
Using the Torx T30 screwdriver, tighten the captive nuts (8 in-lbf) on the DLC module in the order below:
a. In a random order, tighten the first nut three turns.
b. Tighten the nut diagonally opposite to the nut that you tighten first.
c. Repeat the procedure for the remaining two nuts.
d. Return to the first nut to tighten it completely.
e. Check all the nuts to ensure they are firmly secured.
The tubes leading towards the rear of the chassis and the DLC 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), and then place tube 2 and tube 1 into the clip to ensure that cable does not interfere with the PCIe risers.
Route the rear end of the DLC tubes through the RIO board.
NOTE: Follow the number labels on the DLC tubes and ring holders (1,2).
Connect the DLC leak detection cable to the connector on RIO.
Align the rubber ring on the tubes with the ring holder.
Tilt the DLC ring holder and using a Phillips #2 screwdriver, tighten the captive screw on the DLC 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.
Installing the expansion card risers:
If installed, remove the riser blanks and if required loosen the captive screws.
NOTE: Store the riser blanks for future use. Filler brackets must be installed in empty expansion card slots to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.
Holding the edges or the touch points, align the holes on the expansion card riser with the guides on the system board.
Lower the expansion card riser into place and press the touch points until the expansion card riser connector is fully seated on the system board connector.
Tighten the captive screws on the risers and system if any.
Installing the air shroud:
Tilt the air shroud at an angle and align the air shroud tabs with the system slots.
NOTE: Ensure that the air shroud tabs are below the surface of the cooling cage fan assembly.
Lower the air shroud into the system until it is firmly seated.
Replace the system cover.
If applicable, install the system into the rack.
Reconnect the peripherals and connect the system to the electrical outlet, and then power on the system.
