Follow instructions in this section to install a GPU.

About this task

Attention

When the HGX A100 80GB 500W 4-GPU Board is installed and if the ambient temperature is above 30°C, the GPUs may be instructed by the system to enter an emergency power reduction state whereby GPU performance will be impacted.

Important

Removing and installing this component requires trained technicians. Do not attempt to remove or install it without proper training.

Note

Make sure you have an alcohol cleaning pad available.

Attention

• Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

• Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.

• A torque screwdriver is available for request if you do not have one at hand.

Note

To prevent potential thermal issues, change the Misc setting in the BIOS from Option3 (default value) to Option1 if the following two conditions are met:

• The server is equipped with a GPU adapter.

• The UEFI firmware version is U8E128A or later.

For the method of changing the Misc setting, see https://support.lenovo.com/us/en/solutions/TT1832.
