how to install Lenovo ThinkSystem 1U G3 X16/x16 PCIe Riser1 LP+FH Option Kit

• Power down the server, unplug all power sources, and discharge static electricity before beginning any work.
• Remove the server cover or service access panel to expose the motherboard and PCIe riser area.
• Ground yourself and verify you have all required mounting screws and tools per Lenovo documentation.
• Locate the existing PCIe riser slot or the designated riser area for the ThinkSystem 1U G3 chassis; remove any existing module if upgrading.
• Align the PCIe Riser1 LP+FH assembly with the riser slot, ensuring proper orientation to match connector pins and mounting holes.
• Insert the riser gently but firmly into the slot until it seats securely; use the supplied mounting screws to fasten the riser to the chassis or riser bracket as specified by Lenovo.
• Connect PCIe expansion cards to the riser’s x16 sockets, selecting the appropriate slot height (low-profile or full-height) based on card form factors.
• Double-check all connections for security, reseat cards if necessary, and reassemble the server chassis.
• Reconnect power, boot the system, and enter BIOS/UEFI to confirm that the PCIe devices are recognized and operating at the expected speeds; install any required firmware or driver updates.
• Run a baseline stress and performance test to ensure stability and that cooling remains within design specifications under load.
