Install the VR conduction plate for water loop replacement

Use this information to install the VR conduction plate for water loop replacement in the SD665-N V3 tray.

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.

  • VR Conduction Plate 12.0

  • VR 2.5 mm Putty Pad

  • VR 1.5mm Putty Pad

    Putty pad cannot be reused. Whenever the water loop is removed, putty pads must be replaced with new ones before reinstalling the water loop.

Attention

Procedure

Attention
This procedure is ONLY for installing a new water loop. Skip this procedure if you are reinstalling the water loop after replacing the system board, processor, or power distribution board.

  1. Replace the VR conduction plate on the system board with VR Conduction Plate 12.0 .

    1 Shielding cables



For system board with shielding cables

  1. Paste VR 2.5 mm Putty Pad to the VR Conduction Plate 12.4 (including washers).
    1. Remove the two M3 screws to remove the VR conduction plate out of the system board.
    2. Discard the VR conduction plate.

  2. Install the VR Conduction Plate 12.4 (including washers) to the system board.
    1. Locate the screw holes for shielding cable 1/2 and shielding cable 3.

      2 Screw hole for shielding cable 3
      Figure 3. 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 4. Aligning shielding cable 1/2 and shielding cable 3 with screw holes

    3. 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.

    4. 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 6. Pressing on the VR conduction plate

    5. 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.

For system board without shielding cables

  1. Replace the VR conduction plate on the system board with VR Conduction Plate 12.0 .
    1. Remove the two M3 screws to remove the VR conduction plate out of the system board.
    2. Discard the VR conduction plate.
