Remove a PCIe riser assembly

Follow instructions in this section to remove a PCIe riser assembly. The procedure must be executed by a trained technician.

About this task

Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.
  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.
  • If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover, or remove the chassis from the rack. See Remove the server from rack.
  • Two people and one lifting device on site that can support up to 400 lb (181 kg) are required to perform this procedure. If you do not already have a lifting device available, Lenovo offers the Genie Lift GL-8 material lift that can be purchased at Data Center Solution Configurator. Make sure to include the Foot-release brake and the Load Platform when ordering the Genie Lift GL-8 material lift.
  • The server support up to three PCIe risers, see the following illustration for corresponding locations.

Note
To maintain proper system cooling, do not operate the server without a PCIe riser or a riser filler installed in the CPU complex.
