Lenovo 4XF7B08941 SR860 V4 E3.S Chassis Slide Rail

Lenovo 4XF7B08941 SR860 V4 E3.S Chassis Slide Rail

Overview

The Lenovo 4XF7B08941 is a chassis slide rail designed for the ThinkSystem SR860 V4 E3.S platform — the mechanical hardware that lets you pull a fully populated server chassis clear of the rack without disconnecting cables, a routine necessity during drive swaps, PCI card service, and quarterly maintenance windows in high-density data center environments. At 10 lb, the rail assembly reflects the structural mass required to support a fully loaded 4U enterprise server. Manufactured in Mexico and carrying UNSPSC commodity code 43211600 (Computer Equipment), the 4XF7B08941 is a genuine Lenovo field replacement and configuration component sourced through standard commercial channels.

Key Features

• SR860 V4 E3.S Platform Fit: Engineered specifically for the ThinkSystem SR860 V4 E3.S chassis geometry — not a universal rail. This matters because SR860 V4 uses a 4U footprint with specific latch and bracket positions; a mismatched rail creates rack clearance problems and unsafe extension loads.
• 10 lb Rail Assembly Weight: The 10 lb weight indicates a full-depth, heavy-duty slide mechanism rather than a lightweight static shelf bracket — appropriate for a 4U server that can exceed 100 lb fully populated. Proper slide rail mass directly correlates with safe extension load ratings.
• Factory-New Genuine Component: Sourced as a factory-new Lenovo part, not a third-party or refurbished substitute. For slide rails, genuine fit is non-negotiable — aftermarket rails frequently introduce binding, incomplete extension travel, and void the server's structural support warranty.
• UNSPSC 43211600 — Computer Equipment: Correctly classified under the Computer Equipment commodity code, which matters for procurement teams running eProcurement systems (SAP Ariba, Coupa, Oracle iProcurement) that route purchases by UNSPSC category for approval and budget tracking.
• MX Country of Origin: Manufactured in Mexico, relevant for procurement compliance teams tracking TAA eligibility, USMCA sourcing, or supply chain provenance requirements on government and enterprise contracts.

Integration and Compatibility

The 4XF7B08941 is designed for the Lenovo ThinkSystem SR860 V4 E3.S server chassis. Confirm rack unit depth and rail mounting standard (square-hole, round-hole, or threaded) against your existing rack infrastructure before ordering — SR860 V4 rails are engineered for standard 19-inch EIA-310 racks but depth compatibility varies by rack brand. For full Lenovo server accessories and complementary rack components, cross-reference the SR860 V4 hardware maintenance manual for the correct rail part number per rack type. Organizations building out data center rack systems should also verify cable management arm compatibility if CMA options are in use alongside this rail kit.

Frequently Asked Questions

Q: What server model is the Lenovo 4XF7B08941 slide rail compatible with?

A: The 4XF7B08941 is designed for the Lenovo ThinkSystem SR860 V4 E3.S chassis. It is a platform-specific rail, not a universal fit — confirm your exact server model before ordering.

Q: What is the weight of the 4XF7B08941 rail assembly?

A: The rail assembly weighs 10 lb as listed in Lenovo's distribution data. This reflects the structural hardware required for a full-depth 4U enterprise server slide mechanism.

Q: Where is the Lenovo 4XF7B08941 manufactured?

A: The 4XF7B08941 is manufactured in Mexico (Country of Origin: MX), which may be relevant for USMCA sourcing or enterprise supply chain compliance documentation.

Q: Is the 4XF7B08941 a genuine Lenovo part or an aftermarket component?

A: The 4XF7B08941 is a genuine Lenovo component sourced through commercial distribution channels — factory-new, not aftermarket or refurbished.

Q: What UNSPSC code applies to the 4XF7B08941?

A: The applicable UNSPSC code is 43211600 (Computer Equipment), which is used for eProcurement classification in systems like SAP Ariba, Coupa, and Oracle iProcurement.

Ted Perry

The 4XF7B08941 is one of those parts that gets overlooked until it's urgently needed — the SR860 V4 E3.S chassis slide rail that makes a 4U enterprise server serviceable in a live rack environment. At 10 lb, this is a full-depth mechanical slide, not a static shelf bracket, and that weight is structural: it has to safely extend a fully populated server chassis during maintenance without deflection or binding.

Technical Highlights:

• Platform-specific fit: Engineered for the SR860 V4 E3.S chassis geometry — latch positions, bracket spacing, and extension travel are matched to Lenovo's 4U design. This is not interchangeable with SR650 or SR860 V2 rails.
• 10 lb assembly mass: Indicates a robust full-depth slide mechanism. Lightweight rails on heavy servers are a safety and serviceability risk; this assembly is sized for the load.
• MX manufacturing origin: Relevant for procurement teams tracking USMCA compliance or validating supply chain provenance on government or regulated-enterprise contracts.

Deployment Considerations:

• Verify your rack's mounting standard (square-hole, round-hole, or threaded) before installing — SR860 V4 rails are 19-inch EIA-310 compatible but depth and adapter requirements vary by rack manufacturer.
• Evidence for this part is limited to distribution data; cross-reference Lenovo's SR860 V4 Hardware Maintenance Manual for the correct rail SKU per rack type before purchasing — there may be rack-specific variants.

This rail is the right order for data center teams maintaining ThinkSystem SR860 V4 E3.S deployments who need a platform-matched replacement or initial-build slide mechanism — not a general-purpose rack accessory.
