Lenovo 4X97A80408 SR650 V2 3.5 Rear BP Sas/sata CBL V2

Lenovo 4X97A80408 SR650 V2 3.5-Inch Rear Backplane SAS/SATA Cable

Overview

The Lenovo 4X97A80408 is a factory-new SAS/SATA interconnect cable engineered specifically for the ThinkSystem SR650 V2 server platform, serving the 3.5-inch rear backplane assembly. If you are rebuilding a storage configuration, adding a rear drive bay to an existing SR650 V2, or replacing a damaged cable assembly, this is the OEM component that matches the original routing, connector keying, and signal spec — no improvised aftermarket substitutions required. At 2 lb, this is a substantive cable assembly, not a thin patch lead; expect a multi-connector harness sized to the SR650 V2 chassis geometry.

Key Features

• Dual-Protocol Interface (SAS and SATA): Supporting both SAS and SATA on the same cable means you can populate the rear backplane with enterprise SAS drives, cost-optimized SATA drives, or a mixed configuration without swapping cables. This matters in environments where storage tiers are decided post-deployment.
• SR650 V2 Rear Backplane Targeting: This cable is specific to the 3.5-inch rear backplane position on the ThinkSystem SR650 V2. Installing the correct OEM cable eliminates the guesswork around connector positions, cable length, and strain-relief routing — all of which are chassis-specific on rack servers.
• Factory-New OEM Component: Sourced as a genuine Lenovo part, the 4X97A80408 ships factory-new. For datacenter deployments where server hardware is under a service agreement or hardware maintenance contract, using the original Lenovo part number preserves compatibility with Lenovo support and warranty frameworks.

Integration & Compatibility

The 4X97A80408 is designed for use within the ThinkSystem SR650 V2 server platform, specifically the rear 3.5-inch drive backplane assembly. Confirm your SR650 V2 build uses the V2-generation rear backplane before ordering — the SR650 (original) and SR650 V2 share a chassis family but differ in internal backplane and cable routing. The SAS/SATA dual-protocol interface is compatible with standard SFF-8087, SFF-8643, or similar mini-SAS/SAS-to-SATA backplane connectors depending on the specific SR650 V2 backplane option installed; verify your backplane variant against Lenovo's SR650 V2 hardware maintenance documentation before procurement. UNSPSC classification 43211600 (Computer Communications) confirms this is an internal server interconnect component, not an external host bus cable.

Frequently Asked Questions

Q: What server platform is the Lenovo 4X97A80408 designed for?

A: The 4X97A80408 is designed for the Lenovo ThinkSystem SR650 V2 server, specifically the 3.5-inch rear backplane SAS/SATA cable assembly. It is not a universal cable — confirm your exact SR650 V2 backplane configuration before ordering.

Q: Does the 4X97A80408 support both SAS and SATA drives?

A: Yes. The cable supports both SAS and SATA interfaces, allowing you to populate the rear backplane with either drive type or a mixed configuration depending on your storage tier requirements.

Q: What does this cable weigh, and does that matter for installation?

A: The 4X97A80408 weighs 2.00 lb, which reflects a multi-connector harness assembly rather than a simple patch cable. Plan for appropriate cable management inside the SR650 V2 chassis — the weight and bulk are typical for a full backplane cable assembly.

Q: Is this the same cable used in the original SR650 (non-V2)?

A: No. The SR650 and SR650 V2 differ internally, and backplane cables are chassis-generation specific. The 4X97A80408 is specific to the V2 generation. Using a cable from the original SR650 may result in connector mismatches or incorrect cable length.

Karl Wilson

The 4X97A80408 comes up in SR650 V2 deployments when a rear drive bay is being added post-initial-build or when a cable is being replaced under a maintenance event. The dual SAS/SATA interface is the detail that matters most here — it gives you flexibility on the rear backplane without swapping cables if your storage tier decision changes between provisioning and go-live.

Technical Highlights:

• SAS/SATA Dual Interface: A single cable assembly that handles both protocols means the rear bay isn't locked to one drive class at installation time — useful when procurement and storage architecture decisions don't always land simultaneously.
• 2.00 lb Assembly Weight: At 2 lb, this is a harness-class cable, not a lightweight patch lead. That weight reflects multiple connectors and protective sleeving appropriate to a rack server environment — but it also means you need to account for routing and strain relief inside the SR650 V2 chassis during installation.
• OEM Part Specificity: Lenovo part numbers like the 4X97A80408 are generation-specific. The V2 suffix in the cable name is not cosmetic — the SR650 V2 rear backplane differs from the original SR650, and substituting a non-V2 cable risks connector mismatches that won't be obvious until the backplane fails to enumerate.

Deployment Considerations:

• Before ordering, cross-reference your SR650 V2 rear backplane option code against Lenovo's hardware maintenance manual to confirm the 4X97A80408 matches your specific backplane variant — the SR650 V2 supports multiple rear bay configurations, and not all use the same cable.
• This cable is not compatible with the original SR650 (non-V2). The chassis generations share a family name but differ internally; ordering by server model family alone without confirming the V2 generation is a common procurement error on mixed-fleet datacenter rebuilds.

The 4X97A80408 is the right call for an SR650 V2 rear backplane replacement or expansion where the OEM cable specification needs to be maintained — particularly in environments running Lenovo hardware maintenance contracts where non-OEM substitutions affect support eligibility.
