Install the GPU shuttle

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

Procedure

1. Place the free ends of the three rear fan control board cables over the L-shaped edge at the rear-right corner of the system shuttle (as viewed from the rear), ensuring they hang outside the shuttle to prevent damage.
2. Install the GPU shuttle.
   1. Hold the GPU shuttle by the two handles (1) on the GPU baseboard. Then, align the GPU shuttle with the opening at the rear of the system shuttle, and carefully insert it partway.
   2. Push the two handles (1) down.
   3. Push the GPU shuttle fully into the system shuttle until it passes the arrowed lines stamped on the rear of the system shuttle.
   Note

   • DO NOT lift the GPU shuttle by the OSFP support tray.
   • Make sure two people stand on either side of the GPU shuttle, and install it by holding the two handles on the GPU baseboard.

3. Tighten the six screws in the following sequence to secure the GPU shuttle.
   1. First, tighten the two screws marked with F-1.
   2. Then, tighten the four screws marked with F-2.
   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 1.7 newton-meters, 15 inch-pounds.
