Install the GPU complex adapter plate

Follow instructions in this section to install the GPU complex adapter plate. The procedure must be executed by a trained technician.

About this task

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.
  • Two people and one lifting device on site that can support up to 400 lb (181 kg) are required to perform this procedure. If you do not already have a lifting device available, Lenovo offers the Genie Lift GL-8 material lift that can be purchased at Data Center Solution Configurator. Make sure to include the Foot-release brake and the Load Platform when ordering the Genie Lift GL-8 material lift.
Note
Make sure you have the required tools listed below available to properly replace the component:
  • Torque screwdriver which can be set to 0.6 newton-meters, 5.3 inch-pounds
  • Torx T15 extended bit (6-inch long)
Note
The GPU complex adapter plate might look different from the illustration.
