Install an OSFP card and the support tray

Follow instructions in this section to install an OSFP card and the support tray. The procedure must be executed by a trained technician.

Procedure

1. Align the OSFP support tray with the corners on both sides of the GPU shuttle base, and carefully place it onto the GPU shuttle base at an angle as illustrated.
   Figure 1. OSFP support tray installation
   
   
2. Install the OSFP card.
   1. Align the OSFP card with the standoffs on the support tray; then, gently slide and insert the OSFP card into place.
   2. Set the torque screwdriver to 0.9 ± 0.2 newton-meters and tighten the four Phillips #2 screws to secure the OSFP card.

3. If necessary, attach the labels to the end of the UltraPass cables that connect to the GPU baseboard.
   1. Attach the white space portion of the label to one end of the cable.
   2. Wrap the label around the cable and attach it to the white space portion.

4. Connect the UltraPass cables to the GPU baseboard.
   1. Follow the sequence shown in the illustration below ( > > > > > > > ) to install the UltraPass cables (see OSFP card cable routing for more information).
      Figure 4. UltraPass cable installation sequence
      
      
   2. Set the torque screwdriver to 0.59 ± 0.06 newton-meters. Then, loosen the four Torx T8 screws securing the connector cap in the sequence shown in the illustration below ( > > > ) to remove the cap.
      Figure 5. Connector cap removal
      
      
   3. Ensure that a sponge is attached to the inside of the connector cap.
   4. Use an alcohol cleaning pad to clean the UltraPass connector.
   5. Hold the cable by the strain relief area on both sides (1); then, remove the protective cover from the connector.
      Attention

      Make sure to inspect the contact pins and alignment posts on the UltraPass cables. Do not use the cables if any contact pins or alignment posts are damaged.

      Figure 6. Protective cover removal
      
      
   6. Place the protective onto the holder that is located on the wall of the OSFP support tray.

   7. Hold the cable parallel to the GPU baseboard; then, press it straight down into the frame until the latches lock into the slots on the frame.
      Attention

      Do NOT insert the cable at an angle or rotate it within the frame during installation.

   8. Reinstall the connector caps onto the GPU baseboard.
      1. Set the torque screwdriver to 0.15 ± 0.02 newton-meters. Then, fasten the four Torx T8 screws securing the connector cap in the sequence shown in the illustration below ( > > > ).
      2. Set the torque screwdriver to 0.59 ± 0.06 newton-meters. Then, fasten the four Torx T8 screws securing the connector cap in the sequence shown in the illustration below ( > > > ).

   9. Repeat the above steps to connect the remaining cables.
5. If necessary, attach the labels to both ends of the sideband cables.
   1. Attach the white space portion of the label to one end of the cable.
   2. Wrap the label around the cable and attach it to the white space portion.
   3. Repeat to attach the other label to the opposite end of the cable.

   Note

   See the table below to identify the corresponding labels for the cables.

6. Use the OSFP card sideband cable press tool to install the sideband cables to the GPU baseboard and the OSFP cards.
   Attention

   Follow the cable routing instructions to ensure correct cable connections and to prevent misrouting. Incorrect cable connection will cause the GPU baseboard to lose control of the corresponding OSFP connectors.

   • To the GPU baseboard:
     1. Insert the cable into the press tool, ensuring that the grooves on the cable connector face the open side of the tool for correct orientation.
     2. Position the cable so that the closed side of the tool is oriented toward the rear of the GPU baseboard. Keep the cable parallel to the GPU baseboard connector; then, press down firmly until the cable is fully seated.
     3. Repeat to install the remaining cables to the GPU baseboard.

   • To the OSFP card:
     1. Insert the cable into the press tool, ensuring that the grooves on the cable connector face the open side of the tool for correct orientation.
     2. Position the cable so that the closed side of the tool is oriented toward the front of the OSFP card. Keep the cable parallel to the OSFP card connector; then, press down firmly until the cable is fully seated.
     3. Repeat to install the remaining cables to the OSFP card.
