Lenovo 4XH7A96823 SR630 V4 X16 G5 Riser 1 FH

Lenovo 4XH7A96823 SR630 V4 PCIe x16 Gen5 Riser 1 Full-Height

Overview

The Lenovo 4XH7A96823 is a PCIe Gen5 x16 Riser 1 full-height expansion module designed for the ThinkSystem SR630 V4 rack server. Riser cards in this class exist to extend the server's native PCIe slot count and reposition expansion cards within a 1U chassis — critical when deploying GPU accelerators, high-speed network adapters, or storage controllers that require full-height form factor clearance. If your SR630 V4 build requires a Gen5-speed x16 slot in the Riser 1 position, the 4XH7A96823 is the specific assembly to specify.

Compatibility

This riser is designed exclusively for the Lenovo ThinkSystem SR630 V4 platform. It is not interchangeable with SR630 V3, SR650, or other ThinkSystem generations — riser bay dimensions, backplane connectors, and PCIe generation differ across the V3-to-V4 transition, so substituting a prior-generation riser will result in a mechanical or electrical mismatch. Confirm your chassis is specifically the SR630 V4 before ordering. For server expansion components across the ThinkSystem line, verify the riser slot assignment (Riser 1 vs. Riser 2/3) against your SR630 V4 configuration guide, as each position has a distinct part number.

Installation Notes

Install into the Riser 1 bay of the SR630 V4 chassis following Lenovo's hardware maintenance guide for that platform. PCIe Gen5 x16 risers are sensitive to proper seating — an incomplete connection will prevent the installed adapter from being recognized. The full-height designation means the riser supports standard full-height (FH) add-in cards; low-profile cards are not compatible without a separate bracket. Consult the SR630 V4 server accessory compatibility matrix to confirm supported adapter types and thermal envelope before installing high-TDP cards in this slot.
