Lenovo 4X97A90340 SR650 V3 IBM PCIE# 1/2 NVME G5 CBL

Lenovo 4X97A90340 SR650 V3 PCIe/NVMe Gen5 Internal Cable Kit

Overview

The Lenovo 4X97A90340 is a factory-designed internal cable assembly for the ThinkSystem SR650 V3 rack server, purpose-built to connect PCIe and NVMe Gen5 storage devices through the server's primary cable routing positions (PCIE# 1/2). If you are expanding NVMe storage capacity or replacing a damaged cable in an SR650 V3 chassis, this is the OEM-matched part — not a generic aftermarket substitute. At 10 lb, this is a substantial assembly, consistent with a bundled cable kit rather than a single thin flex cable, which means it may include multiple cables or connector housings for the two designated PCIe/NVMe routing positions referenced in the part name.

Key Features

• PCIe and NVMe Interface Support: Wired for both PCIe and NVMe signaling — so a single cable assembly handles the high-bandwidth path needed for Gen5 NVMe drives, which can sustain sequential read speeds well above what SATA or SAS ever delivered. If your SR650 V3 is running an NVMe-heavy storage configuration, getting the correct cable routing is non-negotiable for full bandwidth utilization.
• SR650 V3 Platform-Specific Design: The 4X97A90340 is keyed to the SR650 V3 chassis and backplane layout. Lenovo server internals are notoriously platform-specific — connectors, routing channels, and cable lengths differ across generations. Using the platform-matched part eliminates the guesswork around clearance and fit that comes with aftermarket alternatives.
• Manufactured in Mexico (MX): Country of origin is Mexico, relevant for procurement teams tracking supply-chain geography for compliance or sourcing policy purposes.
• UNSPSC 26121624: Classified under Electronic Components and Supplies — useful for procurement systems that require UNSPSC commodity codes for purchase order categorization.

Integration and Compatibility

This cable is designed for the Lenovo ThinkSystem SR650 V3. Verify your specific SR650 V3 configuration and backplane type before ordering — Lenovo's server configurator documentation or your system's parts list (available via the Lenovo support portal using your machine type) will confirm whether the 4X97A90340 corresponds to your chassis revision. Do not assume cross-compatibility with SR650 (non-V3) or other ThinkSystem platforms without verification.

For SR650 V3 builds requiring high-density NVMe storage as part of a rack server deployment, pairing this cable with verified Gen5 NVMe drives and a compatible Lenovo RAID or HBA adapter ensures the full signal path is spec-matched end to end. Reference the server accessories category for compatible components, or consult a data center infrastructure specialist for build validation.

Frequently Asked Questions

Q: Is the Lenovo 4X97A90340 compatible with the original SR650 (non-V3)?

A: The 4X97A90340 is specified for the SR650 V3. Lenovo server cable assemblies are platform-specific — connector positions and routing paths differ between SR650 generations. Verify compatibility against your exact machine type before ordering.

Q: What does PCIE# 1/2 mean in the part name?

A: It refers to the first and second PCIe/NVMe cable routing positions within the SR650 V3 chassis. This cable assembly services both positions, making it appropriate for configurations that populate both NVMe backplane zones.

Q: Why does this cable kit weigh 10 lb?

A: At 10 lb, the 4X97A90340 is likely a multi-cable kit or includes substantial connector hardware for both PCIe routing positions, rather than a single lightweight flex cable. Confirm exact contents against Lenovo's parts documentation for your SR650 V3 configuration.

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

A: The 4X97A90340 is sourced as a genuine Lenovo component through channel-direct distribution — factory-new, no grey-market, no parallel imports.

Q: What interface does the 4X97A90340 support?

A: It supports PCIe and NVMe interfaces, enabling the high-bandwidth Gen5 NVMe storage paths required in modern ThinkSystem SR650 V3 configurations.

Jerry Tildsen

When I see a cable part weigh in at 10 lb for the 4X97A90340, that tells me this is not a single slim flex cable — expect a multi-piece kit with substantial connector housings covering both PCIe routing positions in the SR650 V3. That matters when you're planning a maintenance window: budget time to route and dress two cable paths, not one.

Technical Highlights:

• PCIe + NVMe Dual Interface: The assembly handles both PCIe and NVMe signaling — critical for SR650 V3 builds using Gen5 NVMe drives, where the cable is part of the full-bandwidth signal path. A mismatched or degraded cable here can cap throughput well below what the drive and controller are capable of.
• Platform Lock to SR650 V3: The part number is specific to SR650 V3 PCIE positions 1 and 2. Lenovo uses unique connector pitches and routing channels across server generations — this is not a universal cable, and ordering the wrong generation part is a common field mistake.
• Mexico Origin (MX): Country of origin is Mexico, which is relevant for TAA or NDAA sourcing audits on federal or regulated deployments — confirm your specific procurement requirements against current regulations before specifying.

Deployment Considerations:

• Confirm your SR650 V3 machine type and backplane revision against Lenovo's official parts matrix before ordering — V3 sub-revisions can have different cable routing requirements even within the same chassis family.
• The 10 lb weight suggests this kit ships with multiple assemblies or bulky connector blocks; verify your chassis has the correct internal clearance and routing guides seated before installation.

Best suited for SR650 V3 environments where NVMe storage expansion or cable replacement is part of a planned maintenance or capacity upgrade — not an ad-hoc cross-platform swap.
