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.

Disconnect the cables from the connector on the system board and the storage tray.

Remove the VSB from the system board and keep it on the storage tray and no need to disconnect from the PDB2:
Using the Phillips 2 screwdriver, remove the screws to disengage the VSB cable from the VSB board connected to the system board.
Disconnect the signal cable from the VSB.
Lift the plunger and slide the VSB tray to rear of the system.
Disengage the VSB tray from the system board and lift it out of the system.
NOTE: The procedure to remove the left and right VSB is similar.
For Intel GPU configurations, remove the storage tray, and then disconnect the VSB cables from the PDB of the bottom layer and disconnect the VSB cables from the system board.
For NVIDIA GPU configurations, disconnect the VSB cables from the system board. Disconnect the VSB cables from the PDB2 of the storage tray. Remove the storage tray. Disconnect the power cable from the PBD of the bottom layer connected on to the PDB2 on the storage tray. Remove the system board tray. Disconnect the VSB cables from the PDB on the bottom layer.
Remove all the screws and lift the VSB from the VSB tray.

Remove the storage tray:
Using a Phillips 1 screwdriver, remove the screws on the drive cage.
Rotate the handle at an angle and slide the storage tray toward the front of the chassis.
Lift the storage tray out of the system.

Remove the risers and keep the risers away from the system board tray and no need to disconnect the cables from the PSB:
For Riser 1B and Riser 4B, using a Phillips 2 screwdriver, loosen the blue thumb screw on the riser.
Remove the turtle shell.
Pull the plunger toward the front of the chassis to unlock the riser.
Disconnect any cables that are connected to the expansion card or the risers from the system board.
Lift the expansion card riser from the riser connector on the system board and keep it away from the system board.
Slide out the system board tray. Disconnect the riser cables connected on the PSB of the bottom layer.

Disconnect all the cables from the system board and make note of all the cable connections.

Remove the lower brace bracket:
Using two fingers press the touch point on the lower brace cover to release it from the lower brace.

Disconnect the liquid cooling tubes 11 and 12 from the Manifold for DLC module and keep in on the system board and make sure do not damage any connectors on the system board.

Slide out the system board tray:
Unlock all the four blue plungers on the system board tray. Rotate the handle upward, and then lock the two blue plungers near to the handle.
Slide the system board tray toward the rear of the chassis until it locks at its position.

Unplug the cold plate tubes from the Manifold Liquid cooling module.

Remove the System board tray:
Unlock all the four blue plungers on the system board tray.
Rotate the handle upward, and then lock the two blue plungers near to the handle. Slightly (around 2 cm) slide out the system board tray until system board tray triangle mark is fully aligned with chassis triangle mark. Using both the hands, one hand holding the handle and another one holding the system handle, lift the tray out of the chassis.

Removing the Manifold module:
Using the Phillips 2 screwdriver, loosen the thumb screws on the lower brace of the chassis. Lift up the lower brace away from the chassis.
Using the Torx 15 screwdriver, remove the screws from the manifold. Lift the tube out of the channel. Slide the manifold toward rear of the chassis along the T-pin and lift up the manifold from the slots on the chassis.

Installing the Liquid cooling Manifold:
First insert the hot tube into the holder and push manifold toward front of the chassis. Using the Torx 15 screwdriver, tighten the screws to secure on the manifold at the front of the chassis. Then insert the cold tube in the holder.
Using the Torx 15 screwdriver, tighten the screws to secure on the manifold at the front of the chassis.
Align and install the lower brace into the chassis. Using the Phillips 2 screwdriver, tighten the thumbscrews to install the lower brace into the chassis.

Plug the GPU cold plate tubes to the Manifold Liquid cooling module.

Slide in the system board tray:
Hold the system board tray handles, slide it toward front of the chassis until the tray firmly locks in its place.
Unlock the two blue plungers near to the handle to release the handle. Rotate the handle and slide the system board tray again to lock in its position. Release the handle until it firmly locks into the chassis. Lock the four blue plungers.

Reconnect the liquid cooling tubes 11 and 12 from the Manifold for DLC module.

Install the lower brace bracket:
Using two fingers press the touch point on the lower brace cover to release it from the lower brace.

Reconnect all the cables onto the system board.

Install the risers:
Reconnect the Riser 1B and Riser 4B cable connectors on the PSB of the bottom layer.
Slide in the system board tray.
For Riser 1B and Riser 4B, holding the blue 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.
Pull the release tab toward the rear of the chassis to lock the riser.
Using a Phillips 2 screwdriver, tighten the blue thumb screw to secure the riser on the chassis.

Install the storage tray:
Align and insert the storage tray on the guiding slots of the chassis.
For tray installation, press down the handle and slide the tray into the chassis toward the rear of the system until it is firmly seated.
Using a Phillips 1 screwdriver, tighten the screws to secure on the drive cage.
NOTE: There is label to show the Storage tray lock and unlock on the left side of the chassis.

Install the VSB cables on the system board:
Align the VSB on the tray and using the Phillips 2 screwdriver, tighten the screws to secure the VSB on to the VSB tray.
Align the VSB on the system board tray. Lift the plunger, align the VSB tray to the system board and slide it toward the front of the system.
Align the power cable to the VSB and secure the cables with the screws. Using the Phillips 2 screwdriver, tighten the screws with torque force 10 in-lbf to secure the VSB on to the VSB tray.
NOTE: The procedure to install the left and right VSBs are same.
For Intel GPU configurations, reconnect the VSB cables on the PDB of the bottom layer. Install the system board tray, and then install the storage tray into the chassis. Reconnect the VSB cables on the system board.
For NVIDIA GPU configurations, reconnect the VSB cables on the PDB of the bottom layer. Install the system board tray, and then install the storage tray into the chassis. Reconnect the VSB cables on the PBD2 of the storage tray and on the system board.
Reconnect the signal cable on to the VSB.

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.
