Lenovo 4X97A90339 SR650 V3 2.5IN Middle BP GEN5 NVME CBL

Lenovo 4X97A90339 SR650 V3 2.5-Inch Middle Backplane Gen5 NVMe Cable

Overview

The Lenovo 4X97A90339 is a factory-new internal NVMe cable designed for the ThinkSystem SR650 V3 server platform, specifically routed to the 2.5-inch middle drive backplane. If you are expanding or replacing storage interconnects in an SR650 V3 build, this is the OEM-matched cable that keeps the Gen5 NVMe signal path intact without adapting or compromising the backplane interface. Genuine Lenovo components sourced from channel-direct distribution — no grey-market, no parallel imports.

The 4X97A90339 connects the middle backplane position in a 2.5-inch drive configuration, supporting PCIe Gen5 NVMe bandwidth. In dense server storage deployments where drive throughput directly impacts workload performance — database hosting, VM storage, video surveillance NVR back-ends — using the correct OEM cable is not optional. A mismatched or third-party cable in a Gen5 NVMe path risks signal integrity errors, reduced link speeds, or backplane detection failures that are difficult to diagnose under load.

Weighing 10.00 lb (shipping weight inclusive of packaging), this cable ships from Mexico and carries UNSPSC code 26121624, classifying it within the standard power and signal cable category for enterprise procurement systems. If your organization's purchasing workflow requires UNSPSC codes for category matching, 26121624 is the correct value to reference for this line item.

Key Features

• NVMe Gen5 Interface: Maintains the full PCIe Gen5 signal path between the SR650 V3 processor complex and the middle 2.5-inch backplane — any downgrade in cable spec here bottlenecks the NVMe drives installed behind it, negating the performance of Gen5 SSDs.
• OEM Lenovo Part: Engineered and validated for the SR650 V3 chassis geometry and backplane connector layout. Field-replacement or build-out installations should use this part to avoid routing clearance issues or connector mismatch that affect cable life under chassis airflow.
• Middle Backplane Position: Specifically routed for the middle bay in a 2.5-inch drive configuration — not interchangeable with front or rear backplane cables in the same server platform without verification against the SR650 V3 cabling guide.

Integration & Compatibility

The 4X97A90339 is designed for use with the Lenovo ThinkSystem SR650 V3 server. Confirm your chassis configuration (drive bay count, backplane model, and processor board revision) against the Lenovo SR650 V3 maintenance manual before ordering. Lenovo's server infrastructure cabling lineup includes separate part numbers for front and rear backplane positions — verify the correct cable by backplane slot position in your BOM. For procurement teams sourcing multiple Lenovo server accessories, cross-reference the Lenovo server accessories catalog to confirm part alignment.

Frequently Asked Questions

Q: What server is the Lenovo 4X97A90339 designed for?

A: The 4X97A90339 is designed for the Lenovo ThinkSystem SR650 V3 server, specifically for the 2.5-inch middle drive backplane position with a Gen5 NVMe interface.

Q: Is the 4X97A90339 compatible with earlier SR650 versions (V1 or V2)?

A: The available evidence does not confirm compatibility with SR650 V1 or V2. This cable is specified for the SR650 V3 platform. Confirm against Lenovo's SR650 V3 maintenance documentation before installing in earlier chassis generations.

Q: What interface does the 4X97A90339 support?

A: The 4X97A90339 supports NVMe (PCIe Gen5), connecting the middle backplane to the system board in the SR650 V3 2.5-inch drive configuration.

Q: Can the 4X97A90339 be used for the front or rear backplane in the SR650 V3?

A: This part is specified for the middle backplane position. Lenovo uses separate cable part numbers for front and rear backplane connections in the SR650 V3 — verify the correct part number against your chassis configuration before ordering.

Q: Where is the 4X97A90339 manufactured?

A: Country of origin is Mexico (MX).

Karl Wilson

The 4X97A90339 is a position-specific NVMe Gen5 cable — the middle backplane slot in the SR650 V3 2.5-inch bay configuration. That distinction matters more than it might appear: Lenovo's SR650 V3 cabling architecture uses discrete part numbers for each backplane position, and substituting the wrong cable in a Gen5 NVMe path is the kind of mistake that shows up as intermittent drive detection or degraded link speeds under sustained I/O, not on bench power-on.

Technical Highlights:

• PCIe Gen5 NVMe Path: Gen5 doubles the per-lane bandwidth of Gen4 — installing a non-spec cable here limits throughput before the drive even becomes the bottleneck. Use the correct OEM part.
• Middle Backplane Specific: The SR650 V3 routes middle-bay drives on a separate signal path from front and rear bays. This cable is not interchangeable across positions — verify bay assignment in your build BOM.
• OEM Sourcing: Factory-new, genuine Lenovo part sourced through channel-direct distribution. Counterfeit or aftermarket cables in high-speed NVMe paths are a known failure vector in dense server deployments.

Deployment Considerations:

• Before ordering, confirm the backplane part number installed in your SR650 V3 matches the 4X97A90339 cable routing spec — Lenovo publishes the cabling matrix in the SR650 V3 maintenance manual, available through the Lenovo Support portal.
• At 10.00 lb shipping weight, budget this into rack freight calculations when ordering multiple cable kits for a larger SR650 V3 fleet deployment.

This part fits cleanly into SR650 V3 deployments being commissioned or expanded for NVMe-intensive workloads — think high-density surveillance NVR back-ends, VM storage clusters, or database servers where the middle-bay drives are part of a tiered NVMe storage configuration.
