Lenovo 4X97A80416 SR650 V2 2.5 Rear BP Sas/sata CBL V2

Lenovo 4X97A80416 SR650 V2 2.5-Inch Rear Backplane SAS/SATA Cable Assembly

Overview

The Lenovo 4X97A80416 is the factory-designated SAS/SATA cable assembly for the ThinkSystem SR650 V2 rear 2.5-inch backplane — a purpose-built internal cable kit that connects the rear drive backplane to the system's storage controller. When you are adding rear hot-swap drive capacity to an SR650 V2, this cable is not optional: the correct signal path from backplane to controller depends on the exact connector configuration this assembly provides. Using an off-spec substitute risks signal integrity issues and falls outside validated Lenovo SR650 V2 storage configurations.

At 2 lbs, the 4X97A80416 ships as a genuine factory component, ensuring physical fitment within the SR650 V2 chassis without modification. The UNSPSC code 43211600 classifies this as computer storage and peripheral hardware — consistent with its role as a direct storage subsystem interconnect, not a generic cable.

Key Features

• Dual-Protocol Interface (SAS and SATA): Supporting both SAS and SATA signaling on a single cable assembly means the rear backplane can host either enterprise SAS drives (higher endurance, dual-port failover) or cost-effective SATA drives interchangeably — without swapping cables. This matters when you are building a mixed-tier storage configuration in the SR650 V2.
• SR650 V2 Platform Fit: Engineered specifically for the ThinkSystem SR650 V2 2.5-inch rear backplane position. Lenovo validates storage configurations at the platform level — using the correct OEM cable (4X97A80416) keeps your storage configuration within supported parameters for firmware and serviceability.
• Factory-New Genuine Component: Sourced as a genuine factory part, not a grey-market or parallel-import substitute. Physical connector keying, cable gauge, and shielding match the SR650 V2 design specification — differences in off-brand alternatives are invisible until they cause intermittent storage faults under load.

Integration & Compatibility

The 4X97A80416 is validated for use with the Lenovo ThinkSystem server line, specifically the SR650 V2 platform with a rear 2.5-inch hot-swap backplane option installed. Before ordering, confirm your SR650 V2 is configured with the rear drive cage option — this cable serves the rear backplane position only and is not interchangeable with front backplane assemblies. For full server storage component compatibility, cross-reference your SR650 V2 system configuration guide to verify the backplane assembly already installed in your chassis matches this cable's connector endpoints. If you are planning a storage expansion project and need to validate the full rear-bay drive configuration, consult your server's product guide for supported storage controller and backplane pairings before selecting drives.

Frequently Asked Questions

Q: What server platform is the 4X97A80416 compatible with?

A: The 4X97A80416 is designed for the Lenovo ThinkSystem SR650 V2 server, specifically connecting the rear 2.5-inch hot-swap backplane to the storage controller. It is not validated for other ThinkSystem platforms.

Q: Does the 4X97A80416 support both SAS and SATA drives?

A: Yes. The cable assembly supports both SAS and SATA interfaces, allowing the rear backplane to accommodate either drive type within the SR650 V2's supported storage configurations.

Q: Is this cable compatible with the front drive backplane on the SR650 V2?

A: No. The 4X97A80416 is specifically for the rear backplane position. Front backplane cable assemblies are separate Lenovo part numbers — verify your system configuration before ordering.

Q: What is the weight of the 4X97A80416?

A: The 4X97A80416 weighs 2.00 lbs as shipped.

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

A: This is a genuine, factory-new Lenovo component sourced through commercial distribution channels — no grey-market or parallel imports.

The 4X97A80416 is one of those parts that only matters when it is missing — and when it is missing, you know it immediately because the rear backplane shows no drives to the controller. This is the designated SAS/SATA signal cable for the SR650 V2 rear 2.5-inch bay configuration, and its dual-protocol interface is what gives you the flexibility to populate that rear cage with either SAS or SATA media depending on workload tier.

Technical Highlights:

• SAS + SATA Dual Interface: A single cable assembly handles both protocols, which means rear-bay drive selection is a procurement decision, not a cabling constraint — swap between SAS enterprise drives and SATA nearline without touching the cable.
• SR650 V2 Platform Specificity: This is not a generic SAS cable — it is a platform-specific assembly with connector placement and keying matched to the SR650 V2 chassis geometry. Off-spec cables may seat but will not conform to Lenovo's validated storage configurations.
• 2.00 lb Packaged Weight: Reasonable indicator that this is a multi-conductor shielded assembly rather than a bare pigtail — the weight is consistent with proper shielding and strain-relief hardware for a rack server environment.

Deployment Considerations:

• Confirm the rear drive cage option is physically installed in your SR650 V2 before ordering — this cable has no function without the rear backplane assembly present in the chassis.
• Evidence covers SAS and SATA interface support only; if your configuration requires NVMe rear drives, verify compatibility with Lenovo's SR650 V2 configuration guide, as NVMe backplane cabling is a different part family.

The 4X97A80416 is the right order when you are commissioning or expanding rear hot-swap storage in a Lenovo ThinkSystem SR650 V2 and need to stay within validated platform configurations — particularly in environments where storage controller firmware compliance and serviceability coverage matter.
