Delve into advanced system maintenance with this comprehensive tutorial. Learn the steps for handling air shrouds, expansion card risers, and liquid cooling modules. Follow each step for a thorough understanding of intricate system components.
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.
Remove the air shroud:
Hold the edges of the air shroud, and lift the air shroud out of the system.
Remove the expansion card riser:
Loosen the captive screws on the riser.
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 liquid cooling (LC) 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 liquid cooling modules.
NOTE: The procedure to remove the processor from the liquid cooling module is same as removing the processor from the PHM.
Removing the liquid cooling module:
Using a Phillips #2 screw driver, loosen the captive screw on the liquid cooling ring holder.
Tilt the liquid cooling ring holder to loosen the liquid cooling tubes.
Disconnect the liquid cooling leak detection cable from the LC RIO board.
Remove the liquid cooling tubes from the clip and LC RIO board.
Slightly lift the liquid cooling tubes surrounding the DIMM slots.
Using a Torx #T30 screwdriver, loosen the captive screws on the liquid cooling module.
NOTE: Ensure the anti-tilt wires on the liquid cooling module are in locked position when loosening the captive screws.
Set the anti-tilt wires on the liquid cooling module to the unlock position and lift the liquid 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 liquid cooling module:
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.
Place the module on the processor slot and set all the anti-tilt wires to locked position (outward position).
Route the liquid cooling tubes on the front of the system between DIMM slots and J_SL connector.
Using a Torx #T30 screwdriver, tighten the captive screws (12 in-lbf).
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.
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).
Connect the liquid cooling leak detection cable to the connector on RIO.
Align the rubber ring on the tubes with the liquid cooling ring holder.
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.
Install the expansion card riser:
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.
Install the air shroud:
Align the slot on the air shroud with the standoff on the system.
Lower the air shroud into the system until it is firmly seated.
