Lenovo 4X97A90342 SR650 V3 2.5IN FIO BP2 NVME CBL KIT

Lenovo 4X97A90342 SR650 V3 2.5-Inch FIO BP2 NVMe Cable Kit

Overview

The Lenovo 4X97A90342 is a factory-new NVMe cable kit designed for the ThinkSystem SR650 V3 server, specifically supporting the 2.5-inch Front I/O (FIO) Backplane 2 (BP2) configuration. When expanding or retrofitting NVMe drive capacity on an SR650 V3, the correct signal cabling between the backplane and the system board is non-negotiable — missing or mismatched cables prevent the backplane from presenting drives to the controller. The 4X97A90342 supplies the exact Lenovo-spec wiring needed to complete a BP2 installation without sourcing generic cables that may not seat correctly or meet signal integrity requirements.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V3 in the 2.5-inch FIO BP2 drive bay configuration. This kit addresses the second backplane (BP2) position — not the primary BP1 backplane. Confirm your SR650 V3 chassis is configured for FIO (Front I/O) and that you are populating or servicing the BP2 backplane before ordering; SR650 V2 and earlier generations use different cable assemblies and are not compatible. If you are working with server storage components across multiple SR650 V3 units, verify the specific backplane slot designation in Lenovo's SR650 V3 hardware maintenance guide before procurement.

Installation Notes

NVMe backplane cabling on the SR650 V3 is keyed and position-specific — route cables per Lenovo's published cable routing diagram for the BP2 slot to avoid improper seating. Ensure the server is fully powered down and discharged before handling internal cable assemblies. The NVMe interface requires secure connector seating at both the backplane and motherboard ends; partial insertion will prevent drive enumeration without producing an obvious physical indicator. Cross-reference the SR650 V3 storage configuration guides for cable routing paths if installing alongside additional server accessories in a dense drive configuration.
