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.

  • SD665-N V3 Water Loop Service Kit (The water loop carrier in the Service Kit is reusable, it is recommended to keep it at the facility where the server operates for future replacement needs.)

  • SD665-N V3 Water Loop Putty Pad Kit

  • SD665-N V3 SXM5 PCM Fixture

  • SXM5 PCM Kit (for removing PCM from GPU)

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

  • Screws and screwdrivers

    Prepare the following screwdrivers to ensure you can install and remove corresponding screws properly.

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.

  • To avoid damaging the water loop, always use the water loop carrier when removing, installing or folding the water loop.

  • A torque screwdriver is available for request if you do not have one at hand.

Firmware and driver download: You might need to update the firmware or driver after replacing a component.
