The Lenovo 4XH7A08779 is a PCIe riser card engineered for ThinkSystem rack servers that use a 2U chassis. Installed in the Riser 1 location, it presents a single PCIe slot capable of operating at x16 or x8 depending on the system board and the card you choose to add. By turning a vertical motherboard connector into a horizontal bay, it lets you integrate expansion hardware such as GPUs, high-speed network adapters, or storage controllers while staying within the height limits of a standard rack.
This riser is fully qualified for the ThinkSystem SR550, SR590, and SR650 platforms, giving administrators a straightforward path to expand compute, networking, or storage performance in mixed-workload environments. Its tool-free design matches the serviceability of the broader ThinkSystem family, so upgrades can be completed quickly during routine maintenance without disrupting airflow or cable routing. Each unit carries part number 4XH7A08779 and barcode 889488461356 to simplify inventory tracking in data centers or IT storage rooms.
