Lenovo 4X97A80409 SR650 V2 3.5 MID BP Sas/sata CBL V2

Lenovo 4X97A80409 SR650 V2 3.5" Mid Backplane SAS/SATA Cable

Overview

The Lenovo 4X97A80409 is a factory-new SAS/SATA backplane cable assembly designed specifically for the ThinkSystem SR650 V2 server platform, targeting the 3.5" mid-bay backplane configuration. If you're expanding drive capacity in an SR650 V2 or replacing a damaged signal cable in an existing mid-bay build, this is the part to source — it matches the connector routing and backplane signaling requirements Lenovo engineered for this chassis generation. At 2.00 lb, it ships as a discrete cable assembly, not a generic aftermarket substitute.

SAS and SATA are both supported over this single cable run, which matters when your SR650 V2 mid-bay population is mixed — enterprise SAS HDDs alongside SATA SSDs on the same backplane segment without requiring a separate cable for each interface type. That flexibility reduces the parts count in dense storage builds and eliminates the need to pre-commit your drive bay allocation to one interface protocol at cabling time.

Key Features

• Dual-protocol SAS/SATA support: A single cable handles both SAS and SATA drive types in the SR650 V2 mid-bay — relevant when populating mixed HDD/SSD configurations without doubling your cable infrastructure.
• SR650 V2 platform-specific fit: Engineered to Lenovo's connector placement and routing for the 3.5" mid backplane position — not a universal substitute that requires guesswork on connector orientation or cable length.
• 2.00 lb assembly weight: Lightweight enough to handle without removing adjacent components, but substantial enough to confirm this is a complete cable assembly rather than a bare connector kit.
• UNSPSC 43211600 classification: Falls under computer storage device components — consistent with how procurement and asset management systems should classify this part for PO and inventory tracking purposes.

Integration & Compatibility

The 4X97A80409 targets the Lenovo ThinkSystem SR650 V2 specifically. Verify your chassis generation — SR650 (V1) and SR650 V2 use different backplane cable routing and connector positions; substituting across generations risks a misfit or signal integrity issue. Confirm your backplane position (mid versus front or rear) before ordering, as Lenovo offers multiple cable variants for different bay configurations within the same chassis. No VMS, NVR, or network integration is applicable to this component — it operates strictly at the server hardware layer.

Frequently Asked Questions

Q: Is the 4X97A80409 compatible with the SR650 V1 or other ThinkSystem models?

A: This cable is specified for the SR650 V2 3.5" mid backplane configuration. SR650 V1 and other ThinkSystem chassis use different backplane and cable designs — confirm chassis generation and bay position before ordering.

Q: Does the 4X97A80409 support both SAS and SATA drives simultaneously?

A: Yes. The cable supports both SAS and SATA interfaces, allowing mixed drive populations in the mid-bay without requiring separate cables per protocol.

Q: What does the 2.00 lb weight indicate about the assembly?

A: It reflects a complete cable assembly with connectors and routing hardware — not a bare wire or partial kit. Verify this matches what your SR650 V2 mid-bay position requires before installation.

Q: Is this a genuine Lenovo part or a third-party substitute?

A: The 4X97A80409 is a factory-new, genuine Lenovo component sourced through authorized distribution channels — no grey-market or parallel imports.

Jerry Tildsen

The 4X97A80409 is a position-specific cable — the SR650 V2 mid-bay 3.5" backplane has a defined connector layout, and Lenovo engineers this cable to match it exactly. I've seen integrators attempt cross-generation substitutions with SR650 V1 cables and end up with connectors that physically fit but route incorrectly, causing intermittent drive drops under vibration. Don't treat backplane cables as interchangeable within a product family.

Technical Highlights:

• SAS + SATA dual-protocol: One cable supports both enterprise SAS HDDs and SATA SSDs in the mid-bay — eliminates the need to stock two cable part numbers when deploying mixed-media storage pools on the SR650 V2.
• Platform-matched geometry: Connector placement and cable routing match the SR650 V2 mid-bay backplane precisely — reduces assembly time and eliminates connector stress from forced routing.
• 2.00 lb complete assembly: Weight confirms this ships as a finished cable assembly with all connectors attached, not a field-crimp kit requiring additional tooling on-site.

Deployment Considerations:

• Verify the exact backplane position (mid vs. front vs. rear) in your SR650 V2 build — Lenovo publishes separate cable part numbers for each bay zone within the same chassis, and ordering the wrong zone cable is the most common fulfillment mistake on SR650 V2 storage builds.
• The SR650 V2 generation distinction matters: V1 and V2 backplane connectors are not pin-compatible in all positions — confirm your chassis nameplate before submitting the PO.

This cable is the correct call for SR650 V2 deployments adding or replacing mid-bay 3.5" drive capacity in high-density storage builds — surveillance NVR backends, media asset servers, or any workload requiring reliable SAS/SATA backplane signal integrity in a 2U rack footprint.
