Lenovo 4XH7A96828 SR630 V4 X16 Gen5 Riser 2 Low-Profile Kit
Overview
The 4XH7A96828 is a PCIe Gen5 x16 Riser 2 low-profile kit for the Lenovo ThinkSystem SR630 V4 rack server. It installs into the Riser 2 slot position and provides a full-bandwidth x16 PCIe Gen5 connection in a low-profile card form factor — critical when you need to add a second expansion card (GPU, HBA, NIC, or capture card) to a 1U chassis that cannot physically accommodate a full-height adapter. Without a riser kit like this one, the SR630 V4's internal slot architecture limits you to a single populated riser position; adding this kit opens the second slot for parallel workloads or redundant connectivity.
Compatibility
Designed and qualified for the Lenovo ThinkSystem SR630 V4 server platform exclusively. The x16 Gen5 electrical interface and low-profile mechanical form factor are specific to the SR630 V4 chassis — this kit is not interchangeable with SR630 V3, SR650, or other ThinkSystem series riser assemblies, which use different slot geometries, latch mechanisms, and PCIe generations. Confirm your chassis generation before ordering; Lenovo riser kits are model-specific and non-transferable across generations. Compatible low-profile adapters (half-length, half-height) are required — full-height cards will not fit the bracket included with this kit.
Installation Notes
Install into the designated Riser 2 bay of the SR630 V4 chassis with the server fully powered down and de-energized per standard ESD protocol. The kit ships with the riser card assembly and bracket hardware; no tools beyond a standard Torx screwdriver are required for the riser cage itself. Slot the riser assembly into the motherboard connector with firm, even pressure until the retention latch engages — partial seating causes PCIe link negotiation failures at boot. Populate only low-profile, half-length PCIe adapters; oversized cards will prevent chassis closure and can stress the motherboard connector. Verify PCIe slot assignment in the SR630 V4 server components configuration guide to confirm Riser 2 is enabled in firmware before installing an adapter card.
