How to install Lenovo ThinkSystem V3 1U x16/x16 PCIe G4 Riser1 LP+LP Option Kit

• Power down the server and disconnect it from power. Ground yourself to prevent electrostatic discharge (ESD) before handling components.
• Remove the chassis cover or access panel to expose the motherboard and PCIe riser area, following the Lenovo ThinkSystem service guide for your specific model.
• Locate the designated PCIe riser connectors and the mounting points for the Riser1 LP+LP kit. Verify that the chassis clearance and backplane support dual x16 expansion cards.
• Align the riser connectors with the motherboard riser slots and firmly seat the Riser1 LP+LP into place. Ensure full engagement with the connectors and that the riser sits flush against the mounting points.
• Secure the riser bracket with the supplied screws or fasteners, as specified in the ThinkSystem hardware manual. Double-check that no cables or cards interfere with the riser’s position.
• Install the PCIe expansion cards into the riser slots as required (GPU, NIC, NVMe controller, etc.), making sure each card is fully seated and properly latched.
• Replace the chassis cover, reconnect power, and boot the server. Enter the BIOS/UEFI to confirm that the newly installed PCIe devices are recognized and configured correctly. Install any necessary drivers or firmware updates from Lenovo or the device manufacturers.
• Once configured, monitor system temperatures and performance to ensure that cooling remains adequate and no thermal throttling occurs in the 1U chassis.

Frequently Asked Questions

Is this riser kit compatible with all Lenovo ThinkSystem V3 1U servers?

The Lenovo ThinkSystem V3 1U x16/x16 PCIe Gen4 Riser1 LP+LP Option Kit is designed for ThinkSystem V3 1U servers and related chassis that support LP+LP dual x16 PCIe Gen4 risers.
