Lenovo 4X97A80399 SR665 2.5" Front 16x NVMe Backplane Cable Kit V2

Overview

The Lenovo 4X97A80399 is the V2 cable kit designed for the ThinkSystem SR665 server, connecting the 2.5-inch front drive bays to NVMe backplane positions 1 and 2 — supporting configurations of up to 16 NVMe drives in the front bay. If you are expanding NVMe storage capacity in an SR665 chassis or replacing a damaged cable assembly, this is the factory-matched component for that specific backplane layout. Lenovo server components like this ship as precisely matched cable assemblies — using a non-OEM substitute risks connector incompatibility and voids the server's coverage.

Key Features

• SR665-Specific Design: Engineered for the ThinkSystem SR665 2.5-inch front bay configuration — connector routing, cable length, and backplane keying are matched to this chassis, so installation does not require modification or adapter hardware.
• 16x NVMe Support via BP1+2: Provides signal and power routing across both backplane 1 and backplane 2 positions, enabling full 16-drive NVMe configurations in the front bay — relevant for storage-dense or high-IOPS workloads where every slot counts.
• V2 Revision: The V2 designation indicates a revised assembly versus prior releases in the same product line — verify your SR665 firmware and backplane hardware revision are compatible with V2 before ordering.
• Compact and Pre-Terminated: At 2.00 lb, the 4X97A80399 ships as a ready-to-install assembly — no field crimping or custom-length cuts required, which reduces installation time during server build-out or maintenance.

Integration & Compatibility

This cable kit is designed for use in the Lenovo ThinkSystem server line, specifically the SR665 platform. Verify your chassis configuration — front bay drive count, NVMe backplane revision, and server generation — against Lenovo's compatibility matrix before deploying. For server component builds requiring NVMe storage expansion, confirm the backplane part numbers already installed in your SR665 match the BP1+2 layout this cable serves. If your SR665 uses a different drive count or a SAS/SATA backplane arrangement rather than NVMe, a different cable assembly will be required. Consult Lenovo's server accessories documentation or pre-sales engineering for multi-node or high-density rack configurations before finalizing your data center component order.

Frequently Asked Questions

Q: Which server platform is the 4X97A80399 designed for?

A: The 4X97A80399 is designed for the Lenovo ThinkSystem SR665 server, specifically supporting the 2.5-inch front bay 16x NVMe configuration via backplane positions 1 and 2.

Q: Does the 4X97A80399 support SAS or SATA drives?

A: Based on the product designation, this cable kit is specific to NVMe backplane connections (BP1+2). It is not confirmed to support SAS or SATA drive configurations — verify with Lenovo's compatibility matrix for your specific SR665 build.

Q: What does the V2 designation mean for the 4X97A80399?

A: V2 indicates a revised version of this cable assembly. Before ordering, confirm that your SR665 chassis and backplane hardware revision are compatible with the V2 iteration, as connector or routing changes may apply versus earlier versions.

Q: How much does the 4X97A80399 weigh?

A: The 4X97A80399 ships at 2.00 lb.

James Everett

The 4X97A80399 is one of those components that looks minor on a BOM but stops a build cold if it is missing or mismatched. This is the V2 cable assembly that bridges the SR665's 2.5-inch front NVMe bays to backplane positions 1 and 2 — without it, none of the 16 NVMe slots in that front zone are functional. At 2.00 lb it ships as a pre-terminated, ready-to-seat assembly, which matters during rack build-outs where technician time is the bottleneck.

Technical Highlights:

• 16-Drive NVMe Span: BP1+2 coverage means this single cable kit serves all 16 front-bay NVMe positions — you are not stacking multiple partial assemblies to reach full bay population.
• V2 Revision: The revision designation matters in high-density NVMe configurations where backplane connector changes between generations can cause silent non-detection rather than an obvious hard fault — confirm your SR665 backplane part numbers before procurement.
• Pre-Terminated Assembly: Factory-terminated cables eliminate field-crimping variables; at 2.00 lb the assembly is manageable inside a populated 2U chassis without cable management tools.

Deployment Considerations:

• Validate the SR665 chassis generation and existing backplane revision against Lenovo's compatibility matrix before ordering — the V2 designation indicates this is not a universal drop-in for all SR665 variants.
• If the SR665 in scope uses a mixed SAS/NVMe backplane layout rather than a pure NVMe BP1+2 arrangement, this cable will not be the correct assembly — pull the server's configuration report first.

The 4X97A80399 is the right specification for SR665 deployments targeting maximum front-bay NVMe density — storage-heavy workloads, all-flash database nodes, or HPC scratch storage configurations where all 16 front slots need to be active and cabled from day one.
