Lenovo 4X97B05773 CBL Conn 160MM MCIO Cable for ThinkSystem SR650 V3

Overview

The Lenovo 4X97B05773 is a 160mm MCIO (Mini Cool Edge IO) cable connector assembly designed for the ThinkSystem SR650 V3 server platform. MCIO is the high-density, high-bandwidth connector standard used in modern 2U rack servers to interconnect NVMe storage backplanes, PCIe expansion modules, and internal riser cards — replacing the older SlimSAS and OCuLink interfaces in current-generation Lenovo server configurations. When internal cabling fails, becomes damaged during a hardware swap, or is missing from a populated chassis, the 4X97B05773 is the correct factory replacement to restore full backplane connectivity without compromising signal integrity.

This is a genuine, factory-new Lenovo cable assembly sourced through the Lenovo server components supply chain — not an aftermarket substitute. Proper fit-and-finish matters in dense 2U chassis: an incorrect cable length or connector type can block airflow, prevent drive cage installation, or cause intermittent NVMe errors that are difficult to diagnose. At 160mm, this assembly is sized for specific internal routing paths within the SR650 V3 chassis — confirm the exact cable position (backplane port, riser slot) against the SR650 V3 Hardware Maintenance Guide before ordering.

Key Features

• MCIO Connector Standard: Supports the high-density PCIe Gen 4/5 signaling requirements of the ThinkSystem SR650 V3's NVMe backplane and storage subsystem — necessary for full-bandwidth NVMe performance.
• 160mm Fixed Length: Matched to specific internal routing paths in the SR650 V3 chassis. Using an incorrect length risks improper seating, strain on connectors, or blocked drive bay access.
• Factory-New Genuine Part: Manufactured in Mexico (MX), shipped as a new Lenovo OEM assembly — avoids the signal-integrity risks of grey-market or reconditioned cable alternatives in production server environments.
• UNSPSC 26121620 Classified: Correctly classified as an electronic connector/cable assembly component, consistent with enterprise server parts and accessories procurement workflows and ERP system coding.

Integration & Compatibility

This cable is designed specifically for the ThinkSystem SR650 V3 platform. It is not a universal MCIO cable — Lenovo's internal cable assemblies are chassis-specific due to length, keying, and routing constraints. Do not substitute this part into SR650 V2, SR630, SR850, or other ThinkSystem models without verifying the exact part number against Lenovo's Hardware Maintenance Guide or Field Replaceable Unit (FRU) list for that chassis. If you are unsure which cable position requires the 4X97B05773, consult the SR650 V3 FRU documentation before procurement — MCIO cables are directional and position-specific. For complete server cable management planning in dense rack environments, verify cable routing diagrams against your installed drive cage and riser configuration.

Frequently Asked Questions

Q: Is the 4X97B05773 compatible with the ThinkSystem SR650 V2?

A: This cable is designed for the ThinkSystem SR650 V3. The SR650 V2 uses a different chassis layout and internal cable routing. Verify the correct FRU part number in the SR650 V2 Hardware Maintenance Guide before ordering.

Q: What connector type does the 4X97B05773 use?

A: The 4X97B05773 uses MCIO (Mini Cool Edge IO) connectors, the current-generation high-density interface used in ThinkSystem SR650 V3 for NVMe backplane and PCIe storage connectivity.

Q: What is the cable length on the 4X97B05773?

A: The cable assembly is 160mm in length, sized for specific internal routing positions within the SR650 V3 chassis. This is a fixed-length assembly — not adjustable.

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

A: The 4X97B05773 is a genuine, factory-new Lenovo cable assembly, manufactured in Mexico and sourced through the Lenovo distribution channel — not an aftermarket or grey-market substitute.

Q: What does this cable connect inside the SR650 V3?

A: MCIO cables in the SR650 V3 interconnect NVMe storage backplanes, PCIe riser cards, and internal storage expansion modules. The exact connection point for this specific 160mm assembly should be confirmed against the SR650 V3 Hardware Maintenance Guide or FRU list for your chassis configuration.

Marty Allison

The 4X97B05773 is a part number I see come up almost exclusively in two scenarios: post-warranty drive cage swaps where the original cable was damaged during removal, and pre-populated SR650 V3 chassis builds where a specific storage configuration requires a cable that wasn't included in the base ship kit. The 160mm length is the critical detail — MCIO cables in the SR650 V3 are not interchangeable by length, and ordering a 250mm or 300mm variant to 'make it work' causes routing problems that affect airflow across the mid-plane.

Technical Highlights:

• MCIO Interface: Supports PCIe Gen 4 and Gen 5 NVMe signaling — the correct interface for full-bandwidth storage performance in the SR650 V3's backplane architecture.
• 160mm Fixed Length: Position-specific within the SR650 V3 chassis; confirms to the chassis routing path without slack management issues that longer cables introduce in 2U environments.
• Mexico (MX) Origin: Manufactured under Lenovo's North American supply chain — relevant for TAA-sensitive government and federal procurement environments where country of origin documentation is required.

Deployment Considerations:

• Confirm the exact cable position number in the SR650 V3 Hardware Maintenance Guide before ordering — the chassis uses multiple MCIO cable assemblies of different lengths for different backplane ports, and the 4X97B05773 is length-specific, not a universal fit.
• This cable weighs 10 lb as shipped (packaged weight) — the cable assembly itself is lightweight; the listed weight reflects packaging and is not indicative of cable mass.

Best fit: SR650 V3 installations requiring a replacement or supplemental 160mm MCIO cable for NVMe backplane or PCIe riser connectivity — particularly in federal, healthcare, or financial data center environments where genuine OEM parts are required for compliance documentation.
