Lenovo 4XH7A61127 SR635 2.5 Sas/sata/anybay 10BAY X40 CBL

Lenovo 4XH7A61127 SR635 2.5-Inch SAS/SATA AnyBay 10-Bay X40 Backplane Cable

Overview

The Lenovo 4XH7A61127 is a factory-new, genuine internal backplane cable designed for the ThinkSystem SR635 server platform. It services a 2.5-inch, 10-bay drive configuration and carries both SAS and SATA signaling over an X40 connector interface — the specific combination required when populating or replacing drive backplane connections in SR635 chassis builds. If you are expanding storage, replacing a failed cable assembly, or provisioning a fresh SR635 for a network video recorder or data storage role, this is the correct OEM component to maintain signal integrity across your drive bays.

Key Features

• Dual-Protocol SAS/SATA Support: The cable carries both SAS and SATA signaling in a single assembly, so you are not locked into one drive type. Mix enterprise SAS drives with SATA SSDs in the same 10-bay backplane without needing a separate cable run for each protocol — relevant when balancing cost and performance across storage tiers.
• 10-Bay AnyBay X40 Configuration: The X40 interface and 10-bay layout are factory-matched to the SR635 2.5-inch backplane. Using the correct Lenovo part number prevents the connector mismatch and signal errors that come from substituting generic or off-platform cables in a high-density drive shelf.
• 10 lb Verified Weight: At 10 lb, the assembly is within normal handling range for a single technician during a chassis swap or cable replacement. No special lifting equipment required for bench-level installation.
• Genuine OEM Component: Sourced as a genuine Lenovo part — no grey-market, no parallel imports. OEM cabling matters in server environments where a non-spec connector can introduce intermittent drive errors that are difficult to diagnose under load.

Integration and Compatibility

The 4XH7A61127 is designed specifically for the Lenovo ThinkSystem SR635 platform. Before ordering, confirm your SR635 chassis revision and backplane model against Lenovo's compatibility matrix — the SR635 has multiple backplane configurations (NVMe, SAS/SATA, AnyBay) and the X40 cable assembly is not interchangeable with NVMe-only or 3.5-inch backplane variants. Review your server accessories bill of materials or existing cable routing to verify this is the correct replacement. Lenovo's Lenovo server platform documentation lists backplane-to-cable mappings by chassis model and configuration code.

Frequently Asked Questions

Q: What server platform is the 4XH7A61127 designed for?

A: The 4XH7A61127 is designed for the Lenovo ThinkSystem SR635 server, specifically the 2.5-inch, 10-bay SAS/SATA AnyBay backplane configuration using the X40 connector interface.

Q: Does the 4XH7A61127 support both SAS and SATA drives?

A: Yes. The cable supports both SAS and SATA protocols, allowing mixed drive populations within the 10-bay backplane — enterprise SAS and SATA SSDs can coexist in the same configuration.

Q: Is the 4XH7A61127 compatible with NVMe backplane configurations?

A: No. The X40 SAS/SATA AnyBay cable is not interchangeable with NVMe-only backplane assemblies. Confirm your SR635 backplane type before ordering.

Q: How much does the 4XH7A61127 weigh?

A: The assembly weighs 10 lb, consistent with a standard internal cable and connector assembly for a 10-bay backplane configuration.

Q: Is this a genuine Lenovo part or a third-party replacement?

A: This is a genuine, factory-new Lenovo OEM component — not a third-party or aftermarket substitute.

Marty Allison

The 4XH7A61127 is a straightforward but easy-to-get-wrong procurement. The SR635 ships in several backplane configurations — SAS/SATA, NVMe, and AnyBay — and each requires its own cable assembly. This X40 connector cable is specifically matched to the 2.5-inch, 10-bay AnyBay backplane variant. Ordering the wrong part means your technician is standing in front of an open chassis with a connector that physically will not seat, and lead times on OEM server cables are not always forgiving.

Technical Highlights:

• SAS + SATA Dual Protocol: A single cable assembly handles both protocols across all 10 bays — no need to run separate SAS and SATA cable sets when mixing drive types in the same backplane shelf.
• X40 Interface Specificity: The X40 connector is platform-locked to the SR635 AnyBay configuration. This is not a universal server cable — it is the correct OEM part for this exact backplane, which also means it seats and performs to spec without adapter plates or force-fitting.
• 10 lb Assembly Weight: Heavy enough that you will notice it during a chassis pull, but well within single-technician handling range for a standard rack service call.

Deployment Considerations:

• Before ordering, pull your SR635's configuration code and cross-reference against Lenovo's backplane compatibility table. The SR635 AnyBay backplane that uses this cable is distinct from the pure SAS/SATA and NVMe backplane variants — the model number alone does not guarantee fit.
• This cable is intended for internal backplane routing inside the SR635 chassis. It is not an external SAS/SATA cable and should not be used as a general-purpose drive connection outside the intended platform.

The 4XH7A61127 is the right call for SR635 deployments in video surveillance NVR racks, storage-dense edge compute nodes, or any infrastructure build where the 2.5-inch 10-bay AnyBay configuration is specified — and where substituting a non-OEM cable introduces an unnecessary failure point in a system that runs continuously.
