Lenovo 4X97A80411 SR650 V2 2.5" Front BP1 Sas/sata Cbl V2

Lenovo 4X97A80411 SR650 V2 2.5" Front Backplane SAS/SATA Cable

Overview

The Lenovo 4X97A80411 is the factory-replacement SAS/SATA front backplane cable (BP1, V2 revision) designed specifically for the ThinkSystem SR650 V2 rack server. If you're building out or repairing an SR650 V2 storage subsystem, this is the OEM cable that connects the 2.5-inch front drive backplane to the system board or HBA — replacing it with a generic alternative risks signaling issues at SAS speeds and is unsupported under Lenovo's service agreements. At 1.20 lb and 11.60 x 9.90 x 2.10 inches, it's dimensioned for the SR650 V2 chassis routing without modification.

Key Features

• Dual-interface SAS/SATA support: The cable carries both SAS and SATA signaling, meaning the SR650 V2 backplane can host a mixed population of SAS HDDs, SATA HDDs, and SATA SSDs on the same BP1 bay group — useful in tiered storage configurations where you're mixing capacity and performance drives without adding a separate expander.
• SR650 V2-specific routing geometry: At 11.60 x 9.90 x 2.10 inches, the cable assembly is routed and terminated to fit the SR650 V2 chassis layout precisely. Forcing a V1 or non-matched cable into the same slot risks connector stress and intermittent drive detection errors — a failure mode that's difficult to diagnose under load.
• V2 revision designation: The V2 suffix on this cable corresponds to the updated SR650 V2 platform. Confirm your server's model badge and service tag against Lenovo's parts matrix before ordering — the SR650 (V1) uses a different cable assembly and the connectors are not interchangeable.
• UNSPSC 43211600 classification: Cataloged under computer storage device cables and interconnects, confirming this is a structured cabling component for enterprise server storage — not a peripheral or power cable.

Integration & Compatibility

The 4X97A80411 is engineered for the Lenovo ThinkSystem SR650 V2, specifically the 2.5-inch front drive bay BP1 backplane. Verify chassis generation before ordering — the SR650 V2 platform revision changes connector placement and cable length relative to earlier SR650 units. For broader server infrastructure planning or to explore compatible storage components for the ThinkSystem line, cross-reference Lenovo's SR650 V2 parts documentation with your service tag. This cable is also relevant to integrators provisioning high-density NVR storage nodes built on SR650 V2 platforms, where reliable backplane connectivity is a prerequisite for sustained write performance across 24/7 recording workloads.

Frequently Asked Questions

Q: Is the 4X97A80411 compatible with the original ThinkSystem SR650 (V1)?

A: No. The 4X97A80411 is designed for the SR650 V2 platform. The V1 and V2 revisions use different backplane connector placements and cable routing geometries. Use your server's service tag to confirm the exact generation before ordering.

Q: Does this cable support both SAS and SATA drives simultaneously?

A: Yes. The cable carries SAS and SATA signaling, so the BP1 backplane can host a mixed population of SAS and SATA devices — HDDs and SSDs — within the same 2.5-inch front bay group.

Q: What is the weight and physical size of the 4X97A80411?

A: The assembly weighs 1.20 lb and measures 11.60 x 9.90 x 2.10 inches, sized to route within the SR650 V2 chassis without modification.

Q: Is this a genuine Lenovo part or an aftermarket cable?

A: This is a genuine, factory-new Lenovo component sourced through distribution — not an aftermarket or grey-market substitute.

Marty Allison

When an SR650 V2 backplane starts dropping drives intermittently, the first thing I check after firmware is the cable — and the 4X97A80411 is the part you need if the BP1 assembly is the culprit. The dual SAS/SATA interface means you're not locked into a single drive protocol on that front bay group, which matters when you're mixing NL-SAS spinners with SATA SSDs in a tiered write configuration.

Technical Highlights:

• SAS + SATA dual-protocol: A single cable assembly handles both protocols across the 2.5-inch front BP1 bay — no secondary adapter or expander needed for mixed drive populations.
• Precise chassis fit (11.60 x 9.90 x 2.10 in): The dimensions are specific to the SR650 V2 routing path. A mismatched cable length or connector angle creates strain at the backplane header — a failure mode that shows up as intermittent SMART errors rather than an outright dead drive, making it harder to catch.
• V2 revision specificity: The V2 designation is not cosmetic — it reflects a physical change in the SR650 platform that makes this cable non-interchangeable with SR650 V1 assemblies.

Deployment Considerations:

• Always cross-reference the server's Lenovo service tag against the parts matrix before ordering — the SR650 and SR650 V2 share a similar chassis profile externally but differ internally at the backplane interface.
• This is a replacement/spare part, not a field-upgrade cable. If you're adding a second backplane to expand bay count, that requires a separate expansion kit; this cable services the BP1 position only.

Best fit for data center teams maintaining SR650 V2 nodes in surveillance storage or enterprise NAS roles where backplane cable integrity directly affects drive array reliability under sustained write loads.
