Lenovo 4X97A59819 SR650 V2 32x 2.5" NVMe Cable Kit
Overview
The Lenovo 4X97A59819 is a factory-matched NVMe cable kit designed for high-density ThinkSystem SR650 V2 server configurations using the 32x 2.5" drive backplane. When you're building out a full 32-bay all-flash NVMe storage configuration in an SR650 V2, the signal cabling between the backplane and the system board is not discretionary — Lenovo specifies exact cable assemblies to ensure proper lane mapping, signal integrity, and mechanical routing in the 2U chassis. This kit supplies the complete cable set for that topology, eliminating guesswork during build-out or field expansion.
Compatibility
Designed for the Lenovo ThinkSystem SR650 V2 server platform configured with the 32x 2.5" NVMe hot-swap backplane. This kit is specific to the NVMe (PCIe) drive interface — it is not interchangeable with SAS/SATA backplane cable sets used in hybrid or SAS-only configurations. Verify your SR650 V2 backplane part number before ordering; the 24-bay and 8-bay NVMe configurations use different cable assemblies. If you are sourcing cables for a server storage expansion project, confirm the exact backplane topology against the SR650 V2 Hardware Maintenance Manual.
Installation Notes
Route cables per the SR650 V2 cable routing guide — NVMe cables are length- and connector-keyed for specific backplane ports and PCIe slots; forcing mismatched connectors risks damaging the backplane signal pins. Ensure the server is fully powered down and discharged before installation. This kit weighs 10 lb, which reflects the full 32-drive cable assembly count; plan accordingly for shipping and handling during rack staging. Interface standard is NVMe; do not substitute SAS or SATA cable assemblies in this bay configuration.
