About this task

S036

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.

• Go to Drivers and Software download website for ThinkSystem SR685a V3 to see the latest firmware and driver updates for your server.

• Go to Update the firmware for more information on firmware updating tools.

Procedure

1. (Optional) Remove the new GPU complex from the package box.
   1. Extend the two handles on both sides of the GPU baseboard.
   2. Hold the two handles, and remove the GPU complex out from the package box.
   Attention

   Make sure two people stand on either side of the GPU complex, and lift it by holding the two handles.

2. Install the GPU complex.
   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 seventeen standoffs on the GPU complex adaptor plate, and gently place it onto the adaptor plate.
   2. Push the two handles (1) down.
   Attention

   Make sure two people stand on either side of the GPU complex, and lift it by holding the two handles (1).

3. Follow the sequence shown in the illustration below to fasten the seventeen 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.

4. (Optional) Complete the following steps for the new GPU complex.
   • Attach the FRU part number label to each GPU and heat sink module.
     1. Remove the protective film from the plastic cover.
     2. Attach the FRU part number label to the plastic cover.
     
     
     
   • Remove the yellow tags from the two handles on both sides of the GPU complex.
     
     
     
5. Flip over the front PCIe switch cable harness.
   1. Flip over the front PCIe switch cable harness, and make sure that it correctly engages the four guide pins on the 8U GPU shuttle.
   2. Locate the ten screw holes marked with C on both sides of the 8U GPU shuttle; then, fasten the ten screws to secure the front PCIe switch cable harness.
