Lenovo 4XF7B04324 SR630 V4 Supercap Holder for Full-Height Slot

Overview

The Lenovo 4XF7B04324 is a mechanical retention bracket designed to secure a supercapacitor (supercap) module in the full-height (FH) expansion slot of compatible ThinkSystem SR630 V4 servers. Supercap modules protect RAID cache data during unexpected power loss — this holder keeps the supercap physically anchored inside the chassis so it stays connected and positioned correctly through vibration and transit. Without a properly fitted holder, the supercap can shift and lose contact, leaving RAID write-back cache unprotected.

Compatibility

Designed for the Lenovo ThinkSystem SR630 V4 server platform, specifically the full-height PCIe slot position that accommodates a supercap module. Verify your SR630 V4 configuration uses the full-height slot variant before ordering — Lenovo offers alternate supercap holder configurations for different slot types within the same server family. This part is not interchangeable across other ThinkSystem generations (SR630 V2, SR630 V3, or other SR-series models) without confirming slot mechanical compatibility via Lenovo's ServerProven or parts documentation for your specific chassis build.
