About this task

Important
Gap pad/putty pad replacement guidelines

  • To identify the gap pad/putty pad location and orientation, see:

  • Before replacing the gap pad/putty pad, gently clean the interface plate or the hardware surface with an alcohol cleaning pad.

  • Hold the gap pad/putty pad carefully to avoid deformation. Make sure no screw hole or opening is blocked by the gap pad/putty pad material.

  • Do not use expired putty pad. Check the expiry date on putty pad package. If the putty pads are expired, acquire new ones to properly replace them.

Required tools

Make sure you have the required tools listed below in hand to properly replace the component.

  • Shielding cable 1, 2, and 3

  • Screws and screwdrivers

Procedure

Note

  • Depending on the model, your solution might look slightly different from the illustration.

  1. Identify the shielding cables.
    Shielding cable
    1 Shielding cable 1 (connected with shielding cable 2 by Y cable)
    2 Shielding cable 2 (connected with shielding cable 1 by Y cable)
    3 Shielding cable 3
    4 Shielding cable 4 (attached shielding cage is smaller than shielding cable 3)
    Figure 1. shielding cable 1/2, 3, and 4

  2. Place shielding cable 1/2 and shielding cable 3 on top of the screw holes on system board.
    1. Locate the screw holes for shielding cable 1/2 and shielding cable 3.
      1 Screw hole for shielding cable 1/2
      2 Screw hole for shielding cable 3
      Figure 2. Location of screw holes of shielding cable 1/2 and 3

    2. Align shielding cable 1/2 and shielding cable 3 to the screw holes on system board. Make sure the ring terminals of the cable are placed in the angle shown below.
      Figure 3. Aligning shielding cable 1/2 and shielding cable 3 with screw holes

  3. Install shielding cable 1/2 and 3.
    1. Keep the FRONT marking on the VR conduction plate pointing the front of the tray. Then, place the VR conduction plate on top of the two cable ring terminals.
      Note

      A putty pad is attached to the bottom side of the VR conduction plate. Carefully hold the VR conduction plate to avoid damaging the putty pad.

    2. Slightly press down the VR conduction plate.
      Attention
      The following items will be secured by screw. Make sure they are aligned and do not block each other.

      • Screw hole on the system board

      • The hole on the ring terminal of the shielding cage cable

      • Screw hole on the VR conduction plate

      Figure 5. Pressing on the VR conduction plate

    3. While pressing down the VR conduction plate, place the screws into the two screw holes on the VR conduction plate. Then, fasten the two screws to secure the cables to the system board. DO NOT fasten the screws until both screws are placed into the VR conduction plate.
      Figure 6. Installing shielding cable 1/2 and 3

  4. Locate the screw hole for braided cable 4. Then, align shielding cable 4 to the screw holes on system board as shown below. Make sure the ring terminal of the cable is placed in the angle shown below. Fasten the screw to secure the shielding cable to the system board.

    Figure 8. Installing shielding cable 4

  5. There are labels attached to shielding cable 1, 3, and 4. Roll the label around the cable all the way through to prevent label interfering with system connectors and water loop.
    Figure 9. Rolling label around the shielding cable

  6. From the inside of the shielding cages, hold the tab and peel off the adhesive tapes. Complete the step for all four shielding cages.

  7. Cover the inductors on system board with shielding cages.
    1. Follow the inductors and shielding cable mapping table below.
      Table 1. Shielding cage and inductors mapping table

      Figure 12. Inductors locations on the system board

    2. Before covering the inductors with shielding cages, make sure the FRONT marking on the shielding cage points at the front of the tray.
      Attention
      After covering the inductors with shielding cages, DO NOT remove the shielding cages from the system board to avoid system board damages.
      Figure 13. Front marking on the cage pointing at the front

    3. Attach the inside of the shielding cage to the inductor attaching point. In the graphic below, the dotted lines specify the inductor attaching points for the inside of the cage. The inductor attaching point is where the inside of the cage and the inductors attach to each other seamlessly without any gap.
      Note

      • Shielding cage 1 and 4: one attaching point

      • Shielding cage 2 and 3: two attaching points

      • For the non-attaching-point side of cage 1 and 4, balance the gap between the inside of the cage and inductors.

      1 Shielding cage
      2 Inductor
      3 Inductor attaching point
      Figure 14. Inductor attaching points

    4. Keep the shielding cage attached to the inductor attaching point and make sure the inductors are completely covered; then, lower the cage into the system board.
      Figure 15. Covering the inductors with the shielding cage

    5. Gently press the top of the shielding cage for three seconds to secure the shielding cage to the inductor. To make sure it is secured to the system board, try to gently pull the cage. If it is not moved, then the shielding cage is successfully installed.
  8. Route the shielding cable 1 between CPU 1 socket and the DIMM slots. Make sure all shielding cable are cleared from CPU sockets, DIMM slots, and other system board connectors.
    Note

    Make sure the FRONT marking on the cage points at the front of the tray.

    2 Shielding cable 2 (connected with shielding cable 1 by Y cable)
    3 Shielding cable 3
    4 Shielding cable 4 (attached shielding cage is smaller than shielding cable 3)
    Figure 16. Cable routing for shielding cages

    The shielding cable 1 should be angled toward CPU 1.



    The shielding cable 4 cable should be angled toward the CPU 2.
