Install a PCIe riser assembly (ConnectX-7 NDR 200)

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

About this task

Required tools

Make sure you have the ConnectX-7 NDR200 Putty Pad Kit to properly replace 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.

Important

Gap pad/putty pad replacement guidelines

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

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

• Go to Drivers and Software download website for ThinkSystem SD665 V3 to see the latest firmware and driver updates for your server.

• Go to Update the firmware for more information on firmware updating tools.
