Use this information to remove a PCIe riser assembly with ConnectX-7 NDR 200 adapter.

About this task

Required tools

Make sure you have the following kits at hand to properly replace the component:
  • Miscellaneous parts kit

  • CX7 NDR200 Thermal Kits (only damaged conduction plate needs to be replaced)

  • ConnectX-7 NDR200 Putty pad kit

Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Turn off the corresponding DWC tray that you are going to perform the task on.

  • Disconnect all external cables from the enclosure.

  • Use extra force to disconnect QSFP cables if they are connected to the solution.

Procedure

  1. Make preparations for this task.
    1. Remove the tray from the enclosure. See Remove a DWC tray from the enclosure.
    2. Remove the tray cover. See Remove the tray cover.
    3. For shared I/O or socket direct configurations, disconnect the cable from the system board. See Internal cable routing.
  2. Loosen the PCIe riser assembly.
    1. Loosen the captive screw on the clamp bracket and remove it.
    2. Loosen the screw on the front of the PCIe riser assembly
    3. Loosen the captive screw on the rear of the PCIe riser assembly.
    4. Remove the two long screws that secure the riser assembly.

    2. Release the interface plate with a flat head screwdriver. (If a flat head screwdriver is not available, the DIMM tool can also be used.)
      1. There are two openings (marked with black triangle in the illustration below) on the bottom side of the interface plate for inserting a flat head screwdriver—select the one that is accessible for the flat head screwdriver.

      2. Insert a flat head screwdriver into the opening; then, slightly rotate the screwdriver to release the interface plate from the water loop cold plate.
