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 GPU fan cage:
Using a Phillips 2 screwdriver, release the two thumb screws on the rear fan cage.
Using both hands pull the left and right handles outward together and pull the complete module out until the safety latch engages with the chassis.
Push the button on both sides to disengage the latch from chassis, then pull GPU fan cage out of the chassis.
Removing the GPU tray:
Using a Phillips 2 screwdriver, release ten capture screws on both side of the chassis.
NOTE: The screw torque is 10 in-lbs and requires additional effort to release the screws.
Using both hands, rotate the handle and slowly pull the GPU tray toward the rear of the system.
Press and release the safety latch on both sides of the GPU tray.
Hold the GPU lifting handle and pull the tray out from the rear of the chassis.
Removing the GPU top cover:
Press the buttons on both sides of the GPU tray top cover and slide the top cover forward.
Lift the GPU top cover from the GPU module.
Removing a H100 GPU:
Identify the failed GPU and lift the NVIDIA plastic cover from the GPU heatsink.
Using Torx 15 screwdriver, release the four outer corner screws securing the GPU and heatsink module.
NOTE:H100/H800 GPU and heatsink module is one part and is removed together.
NOTE:A flashlight will be helpful in locating and identifying the screws clearly.
Using both hands, lift the GPU and heatsink module from the GPU baseboard.
Installing a H100 GPU:
Align and insert the GPU and heatsink module on the GPU socket.
NOTE:H100/H800 GPU and heatsink module is one part and is installed together.
Using Torx 15 screwdriver, tighten the four outer corner screws securing the GPU and heatsink module. Assembly order: 1, 2, 3, 4.
NOTE:Dotted lines represent guiding pins on GPU and heatsink module used for correct alignment and orientation of GPU and Heatsink module.
Align and insert the NVIDIA plastic cover on the GPU heatsink.
Installing the GPU top cover:
Align and place the GPU top cover down.
Push the GPU top cover from the front toward the rear of the GPU tray until it auto-locks by latch on both sides.
Installing the GPU tray:
Lift and align the GPU tray with the rear of the chassis to ensure correct orientation.
NOTE:Two people are needed to carry the GPU tray from each side.
Using both hands, slowly push GPU tray along the track from the rear of the chassis.
NOTE:The GPU tray will slide forward and connect to the connector.
Using both hands, push the handle until it is in a vertical position and self-locks at the same time
Using a Phillips 2 screwdriver, tighten the ten capture screws on both side of the chassis.
NOTE: The screw torque is 10 in-lbs and requires additional effort to tighten the screws.
Installing the GPU fan cage:
Hold the fan cage module and align it with the rear of the system.
NOTE:Ensure that the TOP side mark on the fan cage is in the correct position.
Press the fan cage module firmly into the chassis until it reaches the hard stop position.
Push the fan cage module into the chassis until the handles touch the middle plane.
NOTE:Ensure that the rear fan cage is level and not slanted.
Rotate the left and right handles inward by hand.
Using a Phillips 2 screw driver, tighten the two thumb screws on the rear fan cage.
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.
