18 - 32 kg (39 - 70 lb)32 - 55 kg (70 - 121 lb)
CAUTION
Use safe practices when lifting.
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)
Firmware and driver download: You might need to update the firmware or driver after replacing a component.

Procedure

  1. Hold the handles (1) on both sides of the GPU baseboard in the correct orientation as illustrated; then, align the GPU complex with the thirteen standoffs on the GPU complex adapter plate, and gently place it onto the adapter plate.
    Attention
    Make sure two people stand on either side of the GPU complex, and lift it by holding the two handles (1).

  2. Follow the sequence shown in the illustration below to fasten the thirteen Torx T15 captive screws to secure the GPU complex.
    Important
    Do not overtighten the screws to avoid damage.
    Note
    Loosen or tighten the screws with a torque screwdriver set to the proper torque. For reference, the torque required for the screws to be fully loosen or tighten is 0.6 newton-meters, 5.3 inch-pounds.
