Lenovo 7XH7A05891 ThinkSystem SR530/SR570 x8 PCIe Low-Profile Riser 2 Kit
Overview
The Lenovo 7XH7A05891 is a low-profile PCIe Riser 2 Kit designed to expand the I/O capacity of ThinkSystem SR530 and SR570 rack servers. It provides an x8 PCIe slot via a dedicated riser assembly, enabling you to install an additional low-profile expansion card — such as a network adapter, HBA, or capture card — in systems where the onboard slot count would otherwise be the limiting factor. This is the correct kit when a deployment requires a second expansion slot and the system's chassis supports the Riser 2 position.
Compatibility
The 7XH7A05891 is designed specifically for the Lenovo ThinkSystem SR530 and SR570 1U rack servers. It is not a universal riser — do not attempt to install it in SR550, SR630, SR650, or other ThinkSystem models, as chassis geometry and backplane connector positions differ. Confirm your server's riser bay configuration supports the Riser 2 slot before ordering; some SR530/SR570 configurations ship with this position unpopulated rather than absent entirely.
Installation Notes
This kit ships from Mexico (country of origin: MX) and weighs 0.55 lb. Physical dimensions are 10.00 x 6.00 x 2.00 in, consistent with a standard 1U low-profile riser assembly. Installation requires powering down and fully de-energizing the server before seating the riser. Low-profile card height is enforced by the riser bracket — full-height cards will not fit. Consult the SR530/SR570 hardware maintenance guide for the correct riser bay slot assignment and any torque specifications for the retaining screws.
