Lenovo ThinkSystem 1U G4 x16/x16 PCIe Riser1 LP+FH Option Kit

The Lenovo ThinkSystem 1U G4 x16/x16 PCIe Riser1 LP+FH Option Kit is a purpose-built expansion solution designed for high-density 1U ThinkSystem servers. This dual x16 PCIe riser enables robust I/O expansion in compact chassis, delivering flexible card installation options and maximizing rack efficiency. Built to Lenovo’s enterprise reliability standards, this kit helps data centers scale GPU, accelerator, and high-bandwidth PCIe cards without compromising airflow or serviceability. Whether you are deploying AI accelerators, data processing accelerators, high-speed NVMe controllers, or multi-GPU configurations, this riser kit provides the stable, race-ready bandwidth you need in a 1U form factor.

  • Dual x16 PCIe slots for high-bandwidth expansion: This riser delivers two PCIe x16 slots, allowing you to install power-hungry GPUs, FP7 accelerators, or other high-bandwidth PCIe cards without sacrificing 1U space. The design preserves maximum signal integrity and prevents bottlenecks, helping you unlock full-card performance in a compact server footprint.
  • LP+FH mounting options for broad compatibility: The kit includes both Low Profile (LP) and Full Height (FH) brackets, enabling flexible card heights and convenient deployment in diverse ThinkSystem configurations. This versatility is essential when you need to support different card heights within a single 1U chassis or across multiple servers in a rack.
  • Optimized for 1U density and airflow: Engineered to minimize cable routing complexity and to optimize airflow within tight 1U enclosures. The riser’s footprint is designed to reduce interference with motherboard components while maintaining clear access for installation and maintenance, helping to sustain cooling efficiency in demanding data-center environments.
  • Enterprise-grade reliability and secure installation: Lenovo’s design emphasizes sturdy connectors, precise alignment, and secure mounting to withstand vibration and operational wear. The kit ensures repeatable installation, reduces risk of PCIe slot misalignment, and supports long-term uptime for mission-critical workloads.
  • Easy deployment and future upgrades: The Riser1 LP+FH Option Kit is designed for straightforward field serviceability. Clear labeling, tool-friendly fasteners, and compatibility with ThinkSystem chassis simplify initial setup and future expansions, enabling quick upgrades as your workload evolves.

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

  • Power down the server, unplug all cables, and discharge any static electricity before touching internal components.
  • Remove the chassis cover and identify the PCIe riser slot area on the motherboard as specified by the ThinkSystem service guide for your model.
  • Carefully disconnect any existing PCIe cards or riser cables in the vicinity, noting screw positions and connector orientations to ensure a clean reassembly.
  • Align the Riser1 LP+FH kit with the riser slot, ensuring the connector pins mate securely with the motherboard header and that the LP and FH brackets align with the chassis cutouts.
  • Secure the riser kit using the included fasteners in the correct locations. Attach the LP or FH brackets as required by your card height and chassis configuration.
  • Install your PCIe cards into the dual x16 slots, applying even pressure to seat cards fully into the riser connectors. Add any necessary screws to secure each card to the chassis or riser plate.
  • Re-route or manage cables to minimize obstruction of cooling airflow and to prevent accidental card displacement. Ensure that no cables press against the PCIe connectors or bracket edges.
  • Replace the chassis cover, reconnect all power and data cables, and power on the server. Enter the system BIOS/UEFI to verify that the PCIe devices are detected and operating at expected lane configurations.
  • Run a basic post-power-on self-test (POST) and a PCIe device check to confirm stability and correct operation under load. If any device is not recognized, reseat the card or consult Lenovo support resources for troubleshooting guidance.
