Install a PCIe riser assembly (ConnectX-6)

Use this information to install a PCIe riser assembly with ConnectX-6 adapter.

About this task

Required tools

Make sure you have the following kits at hand to properly replace the component:

  • Miscellaneous parts kit (03KH873)

  • Conduction plate parts (03KH864) (only damaged parts need to be replaced)

  • ConnectX-6 Putty pad kit (03LD667)

Important
Gap pad/putty pad replacement guidelines

  • To identify the gap pad/putty pad location and orientation, see Gap pad and putty pad identification and location.

  • 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.

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.

  • After updating XCC firmware, perform virtual reseat via SMM2 to optimize system, see SMM2 User Guide.

Procedure

  1. Remove the blank bezel fillers if they are installed.

Make sure to follow Gap pad/putty pad replacement guidelines.

  1. Install the PCIe riser assembly.
    1. Install one hex standoff screw to the cold plate.
    2. Align the tab on the PCIe riser assembly with the slot on the front of the node; then, insert the PCIe riser assembly onto the system board.
    3. Secure the riser assembly with one screw.

After you finish

  1. Install the tray cover. See Install the tray cover.

  2. Install the tray into the enclosure. See Install a DWC tray in the enclosure.

  3. Connect all required external cables to the solution.
    Note
    Use extra force to connect QSFP cables to the solution.

  4. Check the power LED on each node to make sure it changes from fast blink to slow blink to indicate all nodes are ready to be powered on.
