Lenovo 4X97A80402 SR645 6+4 AnyBay 2.5-Inch SAS/SATA Backplane Cable V2

Overview

The Lenovo 4X97A80402 is a replacement and expansion backplane signal cable designed for the ThinkSystem SR645 rack server, connecting the 6+4 AnyBay 2.5-inch drive backplane to the system board or RAID adapter. If you are reconfiguring an SR645 storage bay or replacing a damaged signal path, this is the part number to source — it carries both SAS and SATA signaling in a single cable assembly, giving the AnyBay backplane the flexibility it was engineered for.

The V2 designation indicates a revised assembly that aligns with later SR645 configurations. At 2.00 lb, this is a standard internal cable assembly — weight is relevant if you are shipping a field-repair kit or managing parts inventory by weight for logistics. The dual SAS/SATA interface support means the backplane can serve either drive protocol without swapping cables, which is the practical value of the AnyBay design: one bay, one cable run, and you choose SAS or SATA drives at the slot level based on workload and budget.

Compatibility and Integration

The 4X97A80402 is specific to the Lenovo ThinkSystem SR645 platform. If you are integrating this into a Lenovo server build or field-servicing an SR645 within a rack server environment, verify the chassis generation and backplane revision against Lenovo's SR645 parts documentation before ordering — AnyBay backplane cable revisions are not universally cross-compatible across all SR645 production runs. The SAS/SATA dual interface aligns with standard server storage configurations where mixed drive populations or phased upgrades are planned. Consult a storage networking or server infrastructure guide if you are designing the full drive bay and HBA/RAID topology for the SR645.

Frequently Asked Questions

Q: What server platform is the Lenovo 4X97A80402 designed for?

A: The 4X97A80402 is designed for the Lenovo ThinkSystem SR645 rack server, specifically for the 6+4 AnyBay 2.5-inch drive backplane configuration.

Q: Does the 4X97A80402 support both SAS and SATA drives?

A: Yes. The cable assembly carries both SAS and SATA signaling, which is the purpose of the AnyBay backplane design — allowing either drive protocol to be used at the slot level without a cable swap.

Q: Is this a factory-new genuine Lenovo part?

A: Yes. This is a factory-new, genuine Lenovo component sourced through distribution channels — not a grey-market or parallel-import substitute.

Q: How much does the 4X97A80402 weigh?

A: The assembly weighs 2.00 lb, which is useful to know when planning field-repair kits or logistics for parts shipments.

Q: Is the V2 version of this cable backward compatible with earlier SR645 backplane revisions?

A: Backplane cable revisions on the SR645 platform should be verified against Lenovo's official SR645 parts compatibility documentation for your specific chassis production run before assuming cross-revision compatibility.

Karl Wilson

The 4X97A80402 is the kind of part that gets overlooked until a drive bay goes dark or an SR645 storage reconfiguration stalls mid-project. What matters here is the dual SAS/SATA interface on a single cable — that is the functional core of the AnyBay backplane and the reason you do not need separate cable assemblies for each drive protocol in the same bay group.

Technical Highlights:

• Dual SAS/SATA Interface: A single cable run supports both SAS and SATA drive protocols at the backplane level, eliminating the need to swap cables when mixing drive types or transitioning from SATA to SAS in a phased storage upgrade on the SR645.
• AnyBay 6+4 Configuration: The 6+4 bay layout gives the SR645 flexibility to mix NVMe, SAS, and SATA drives in the same physical backplane — this cable is the signal path that makes that flexibility work in practice.
• V2 Revision: The V2 designation tracks with later SR645 production configurations; using the correct cable revision matters for signal integrity and fit within the chassis cable routing.

Deployment Considerations:

• Confirm your SR645 chassis generation and backplane part revision before ordering — Lenovo AnyBay backplane cables are not always interchangeable across all SR645 production runs, and a mismatch will require a second sourcing cycle.
• At 2.00 lb, this is a heavier assembly than a simple signal cable; handle with care during installation to avoid connector stress on the backplane socket.

The 4X97A80402 is the right sourcing target for SR645 deployments that need field cable replacement or are reconfiguring a storage bay to support mixed SAS/SATA drive populations — particularly in data center environments running the SR645 as a primary storage node where bay flexibility is part of the original design intent.
