Lenovo 4M17A61304 SR630 V2 Supercap Holder Kit
Overview
The Lenovo 4M17A61304 is a supercapacitor holder kit designed for installation in Lenovo ThinkSystem servers. The supercap holder physically secures the RAID controller's supercapacitor module inside the chassis — keeping it properly seated and protected during operation and transit. Without a correctly mounted holder, the supercap can shift under vibration or during cable management, risking loss of RAID cache-protection that guards against data loss during unexpected power failures. Part number 4M17A61304 covers the SR630 V2 platform and is the factory-correct fitment for that chassis geometry.
Compatibility
This holder kit is designed for the Lenovo ThinkSystem SR630 V2 rack server. Verify your specific RAID controller and chassis revision against Lenovo's compatibility matrix before ordering — supercap holder geometry varies across ThinkSystem generations and the SR630 V2 chassis differs from the original SR630. This part is not interchangeable with holders for the SR650, SR550, or first-generation SR630 without confirmation. For broader server accessory fitment questions across the ThinkSystem line, cross-reference the SR630 V2 product guide or server components listing for your generation.
Installation Notes
The kit weighs 0.30 lb and measures 4.00 x 9.00 x 2.50 in — a compact, tool-friendly form factor suited to the SR630 V2's internal bay layout. Follow the ThinkSystem SR630 V2 rack server maintenance manual for supercap installation sequence: the holder must be secured before connecting the supercap cable to the RAID controller to avoid stress on the connector. No torque specifications or special tooling are documented in the available evidence for this kit beyond standard Lenovo server assembly practices.
