The Lenovo 4XH7A09847 is a supercapacitor installation kit designed for the ThinkSystem SR635 and SR655 rack servers. Supercapacitors serve as the flash-backup power source for RAID controllers — when mains power drops unexpectedly, the supercap provides enough energy to flush the controller's write cache to non-volatile storage, protecting in-flight data. This kit delivers the hardware needed to add or replace that protection in the SR635/SR655 chassis without sourcing individual components separately.
Designed specifically for the Lenovo ThinkSystem SR635 and SR655 rack servers. These are AMD EPYC-based 1U/2U platforms in the ThinkSystem portfolio. Verify your existing RAID controller model against Lenovo's configurator before ordering — not all SR635/SR655 RAID adapters use the same supercap form factor. This kit is not compatible with Intel-based ThinkSystem platforms (SR630, SR650, SR670) or ThinkAgile/ThinkEdge lines. If you are outfitting a rack server storage environment with multiple nodes, confirm per-slot supercap requirements against your RAID adapter count.
The kit ships at 1.35 lb in a 2.20 × 10.00 × 11.00 in package — standard accessory dimensions for a chassis-internal component. Installation is performed inside the server chassis with the system powered down and grounded per ESD protocol. Consult the SR635/SR655 Hardware Maintenance Manual for exact bay location, cable routing, and retention clip orientation before starting. No special tooling beyond a standard Torx/Phillips set is indicated by the distribution data, but always cross-reference the Lenovo service guide for your specific server revision. For environments running high-availability storage where write-cache protection is mission-critical, plan this installation during a scheduled maintenance window rather than treating it as a hot-swap procedure.
