Lenovo 4XF7B08886 SR850 V4 2.5 Chassis Left Latch Option

Lenovo 4XF7B08886 SR850 V4 2.5" Chassis Left Latch Option

Overview

The Lenovo 4XF7B08886 is the OEM left latch option for the ThinkSystem SR850 V4 server platform configured with a 2.5" drive bay chassis. If you are rebuilding, repairing, or commissioning a replacement SR850 V4 chassis assembly and the left latch is missing, damaged, or was not included with a secondary unit, this is the exact Lenovo-sourced part that restores correct mechanical function and chassis integrity. Using the genuine OEM latch — rather than a fabricated substitute — ensures the drive bay door seats and releases correctly under repeated rack service cycles without deforming the retention mechanism or voiding the platform's mechanical warranty coverage.

Key Features

• Platform-specific fit: Designed and sourced exclusively for the SR850 V4 2.5" chassis form factor — not a universal latch, not cross-compatible with the 3.5" variant. Ordering the correct side (left) matters; confirm your chassis orientation before purchasing.
• Genuine Lenovo hardware: Factory-new OEM component sourced through the Lenovo distribution channel. No aftermarket substitutes, no grey-market or parallel-import parts — the latch engages the chassis precisely as the SR850 V4 platform was designed to operate.
• Weight — 10 lb: At 10 lb, this option ships as a standalone unit. Factor the weight into freight planning if ordering alongside other rack components in the same shipment.
• Country of origin — Mexico: Manufactured in Mexico (MX), consistent with Lenovo's North American supply chain for ThinkSystem platform components.

Integration & Compatibility

The 4XF7B08886 is validated for the Lenovo ThinkSystem SR850 V4 server with a 2.5" drive bay chassis configuration. It is not validated for SR850 V3 or earlier generations, the SR860 platform, or any 3.5" chassis variant of the SR850 V4. If you are unsure which latch your chassis requires, cross-reference your SR850 V4 order code against the Lenovo ThinkSystem SR850 V4 product guide — the chassis type (2.5" vs. 3.5") and latch side (left vs. right) are both encoded in the system configuration string.

Frequently Asked Questions

Q: Is the 4XF7B08886 compatible with the SR850 V3?

A: No. The 4XF7B08886 is specified for the SR850 V4 2.5" chassis. Compatibility with earlier SR850 generations is not confirmed by available evidence — verify against your chassis generation before ordering.

Q: Is this the left or right latch?

A: This is the left latch option for the SR850 V4 2.5" chassis. If you need the right-side latch, verify the correct Lenovo option part number before purchasing.

Q: Is the 4XF7B08886 a genuine Lenovo part?

A: Yes. It is a factory-new OEM component sourced through the Lenovo distribution channel — no aftermarket or grey-market substitutes.

Q: Does this part work with the SR850 V4 3.5" chassis?

A: No. This latch is specific to the 2.5" drive bay chassis configuration of the SR850 V4. The 3.5" chassis variant requires a different option part number.

Ted Perry

The 4XF7B08886 is a straightforward OEM mechanical replacement — a left latch for the Lenovo ThinkSystem SR850 V4 2.5" chassis. At 10 lb, it ships as a standalone unit and the weight is the only spec available from distribution data, which tells you exactly what this part is: a structural chassis component with no electronics, no firmware, no configuration.

Technical Highlights:

• Platform specificity: Designed for SR850 V4 2.5" chassis only — the latch geometry is not interchangeable with 3.5" variants or prior SR850 generations, so ordering the wrong part means a return, not a workaround.
• Genuine OEM sourcing: Factory-new Lenovo-channel part eliminates the fitment risk of aftermarket latches, which often have looser tolerances and can cause recurring drive bay door misalignment under rack vibration.
• Weight: 10 lb: Heavier than expected for a latch assembly — factor this into freight consolidation if ordering with other rack options in the same PO.

Deployment Considerations:

• Confirm your SR850 V4 chassis is the 2.5" configuration before ordering — the 3.5" variant uses a different latch part number and the two are not interchangeable.
• Evidence is limited to distribution feed attributes only; no Lenovo product guide or field replacement documentation is in evidence, so cross-reference the Lenovo ThinkSystem SR850 V4 Parts Reference for torque specs and installation sequence before replacing in a production chassis.

The right fit for a data center team maintaining an SR850 V4 fleet where a damaged or missing left latch is blocking chassis reassembly after a drive bay service event.
