Lenovo 4X97A80413 SR650 V2 2.5 Front BP2 Sas/sata CBL V2

Lenovo 4X97A80413 SR650 V2 Front Backplane SAS/SATA Cable

Overview

The Lenovo 4X97A80413 is a replacement and spare SAS/SATA backplane interconnect cable designed specifically for the ThinkSystem SR650 V2 rack server platform. If you're servicing or expanding storage in an SR650 V2 and need to restore or extend the 2.5-inch front drive backplane signal path, this is the part that does it — a purpose-built internal cable routed between the server's second front backplane (BP2) and its storage controller or expander. Weighing just 0.50 lb and measuring 9.50 × 5.90 × 2.20 inches, the 4X97A80413 fits within the SR650 V2's chassis geometry without modification.

Key Features

• Dual-protocol SAS/SATA interface: Supporting both SAS and SATA signaling on the same cable run means you're not locked into a single drive technology. You can populate BP2 with enterprise SAS drives for higher IOPS and reliability, or SATA SSDs/HDDs where cost-per-terabyte matters more — without changing the cable.
• SR650 V2 platform-specific fit: This cable is engineered to the exact connector positions and routing path of the SR650 V2's 2.5-inch front backplane 2 (BP2) slot. Using a generic or mismatched cable in a server this dense risks connector stress, improper seating, and intermittent drive faults that are difficult to diagnose. The 4X97A80413 eliminates that risk.
• Compact, chassis-optimized form factor: At 9.50 × 5.90 × 2.20 inches, the cable assembly is sized to thread cleanly through the SR650 V2's internal cable management channels. Proper routing in 1U/2U rack servers directly affects airflow — a misrouted or oversized cable can impede cooling across the drive bay.
• Low-weight serviceability: The 0.50 lb weight keeps the internal cable load minimal during hot-plug drive operations, reducing mechanical stress on backplane connectors over time — relevant in high-turnover storage environments where drives are swapped regularly.
• UNSPSC 43211600 classification: Categorized under Computer Storage Devices and Accessories, this part aligns with standard procurement taxonomy used by enterprise purchasing systems, simplifying PO generation and asset tracking in environments that enforce commodity code compliance.
• Factory-new genuine component: Sourced through channel-direct distribution — factory-new, no grey-market, no parallel imports. For a server platform where cable integrity directly affects drive data paths, using genuine components matters: third-party cables introduce connector tolerance variability that can manifest as intermittent CRC errors under load.

Integration & Compatibility

The 4X97A80413 is designed for the Lenovo ThinkSystem SR650 V2 server, specifically the 2.5-inch front backplane 2 (BP2) configuration. It carries SAS and SATA signals, making it compatible with the range of SAS/SATA drives and storage controllers supported in that platform. Before ordering, confirm your SR650 V2's specific backplane topology — Lenovo offers multiple front drive configurations on the SR650 V2 (8-bay, 16-bay, 24-bay, NVMe variants), and the correct cable depends on which backplane slot is being served. This cable is designated for the BP2 position in a SAS/SATA build; NVMe backplane configurations require different cabling. Cross-reference the SR650 V2 maintenance manual or Lenovo server accessories listings to confirm the right part for your chassis configuration.

For broader SR650 V2 storage builds, pair this cable with compatible server storage components and ensure your HBA or RAID controller has the corresponding mini-SAS HD port available. If you're sourcing multiple internal server cables or planning a storage expansion, reviewing a storage architecture guide for the SR650 V2 platform will help map controller port assignments to backplane positions before you pull the server from the rack.

Frequently Asked Questions

Q: What server platform is the Lenovo 4X97A80413 designed for?

A: The 4X97A80413 is designed for the Lenovo ThinkSystem SR650 V2 rack server, specifically for the 2.5-inch front backplane 2 (BP2) SAS/SATA cable position.

Q: Does the 4X97A80413 support both SAS and SATA drives?

A: Yes. The cable supports both SAS and SATA interface protocols, giving you flexibility to populate BP2 with either SAS or SATA drives depending on your performance and capacity requirements.

Q: What are the physical dimensions of the 4X97A80413?

A: The cable assembly measures 9.50 × 5.90 × 2.20 inches (L × W × H) and weighs 0.50 lb.

Q: Will the 4X97A80413 work in other Lenovo SR650 configurations or earlier SR650 revisions?

A: Based on available evidence, this cable is specified for the SR650 V2 platform. Compatibility with the original SR650 (V1) or other ThinkSystem models is not confirmed in the source data — consult Lenovo's parts compatibility tool before ordering for a different chassis revision.

Q: Is this cable compatible with NVMe backplane configurations in the SR650 V2?

A: No. The 4X97A80413 is a SAS/SATA backplane cable. NVMe front drive configurations on the SR650 V2 require separate, NVMe-specific cabling — this part does not carry PCIe/NVMe signals.

Ted Perry

The 4X97A80413 is one of those parts that looks trivial until you're standing in front of a half-populated SR650 V2 with a backplane BP2 that won't initialize. At 9.50 inches long and 0.50 lb, the cable is a precision fit for Lenovo's 2.5-inch front drive topology — and on a dual-protocol SAS/SATA path, a damaged or misrouted cable doesn't just drop one drive, it takes out the entire backplane segment.

Technical Highlights:

• SAS/SATA dual protocol: A single cable carries both SAS and SATA signaling to BP2, so you're not committed to a drive type at cable-ordering time. Swap drive technology without rewiring.
• Chassis-matched geometry (9.50 × 5.90 × 2.20 in): The dimensions match the SR650 V2's internal cable routing channels exactly — critical in a 2U chassis where airflow resistance from a poorly routed cable can push hotspot temps above drive operating thresholds during sustained read/write.
• Factory-new genuine part: Connector tolerance on backplane cables is tight. Third-party alternatives often introduce marginal seating depth that passes initial POST but generates intermittent CRC errors under sustained sequential writes — the kind of fault that doesn't show up until a storage stress test or a real workload event.

Deployment Considerations:

• Before installing, confirm which backplane slot your SR650 V2 is configured for — Lenovo sells multiple front-bay options (8, 16, 24 drives; SAS/SATA vs NVMe). The 4X97A80413 is BP2-specific; ordering the wrong variant means the connector keying won't mate correctly.
• On a production SR650 V2, always power down fully before replacing internal SAS/SATA cables — unlike hot-plug drives, the backplane interconnect is not a live-swap component, and connector damage under voltage can corrupt the entire storage pool.

This part makes the most sense as a stocked spare for data centers running multiple SR650 V2 nodes on SAS/SATA storage tiers — particularly in surveillance NVR infrastructure or backup-target servers where BP2 is fully populated and a cable fault creates a hard service window.
