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.

Procedure

1. Align the GPU complex adapter plate with the guide pins in the bottom of the system shuttle; then, lower the adapter plate into the shuttle.

2. Locate the fourteen screw holes marked with an arrow; then, follow the sequence shown in the illustration below to fasten the fourteen screws to secure the GPU complex adapter plate.
   Note

   Tighten the screws with a torque screwdriver set to the proper torque. For reference, the torque required for the screws to be fully tighten is 0.5 newton-meters, 4.3 inch-pounds.

3. 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 standoffs on the GPU complex adapter plate, and gently place it onto the adapter 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).

4. Follow the sequence shown in the illustration below to fasten the eighteen 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±0.024 newton-meters, 5.3±0.212 inch-pounds.

6. Install the bulkhead.
   1. Hold the bulkhead in the correct orientation as illustrated, and slide it into the system shuttle.
   2. Locate the eight screw holes marked with A on both sides of the system shuttle; then, fasten the eight screws to secure the bulkhead.
   
   
   
7. Install the support bracket.
   1. Hold the bracket in the correct orientation as illustrated, and lower it into the system shuttle.
   2. Fasten the two screws to secure the support bracket.
   
   
   
8. Push the PCIe switch shuttle fully into the system shuttle.
   1. Press the two front lock latches on both sides of the PCIe switch shuttle.
   2. Push the PCIe switch shuttle fully into the system shuttle.
   3. Rotate the two release levers until they lock into place.
