About this task

Important

Gap pad/putty pad replacement guidelines

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

  • Required Tools list in the following section.

  • Gap pad/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.

Required tools

Make sure you have the ConnectX-7 NDR200 Putty Pad Kit to properly replace the component. Putty pad cannot be reused. Whenever a component is removed, putty pads must be replaced with new ones before reinstalling the component.

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.

Note

• For more information on selecting riser slot for PCIe riser installation, see Internal cable routing.

Attention

The type of PCIe riser installed in slot 1 and slot 2 are different. Cable-ended riser must be installed in Slot 1. See the illustration below for proper PCIe riser installation.
