Lenovo 7XH7A05903 DCG Thinksystem ST550 4U

Lenovo 7XH7A05903 ThinkSystem ST550 4U Rack Component

Overview

The Lenovo 7XH7A05903 is a factory-new rack-mount component designed for the ThinkSystem ST550 4U server platform. At 1.50 lb and measuring 17.90 × 7.60 × 2.70 inches, the physical profile is consistent with a rail assembly or structural rack accessory — sized to fit standard 19-inch rack enclosures at the 4U form factor. It ships from a Mexico manufacturing origin under UNSPSC commodity code 43201601 (Servers and server components).

If you are provisioning or expanding a ThinkSystem ST550 infrastructure, the 7XH7A05903 is a Lenovo-sourced component intended to keep installations within factory specification — relevant when maintainability, parts interchangeability, or service agreement compliance is a requirement.

Key Features

• 4U Rack Form Factor: Dimensioned at 17.90 × 7.60 × 2.70 inches to fit standard 19-inch EIA rack enclosures at 4U height — no field modification required for ST550 deployments in properly specced rack cabinets.
• Lightweight at 1.50 lb: The sub-2 lb weight simplifies single-technician installation without specialized lifting equipment, keeping rack work efficient during initial build-out or component swap.
• Factory-New, Genuine Part: Sourced through verified distribution channels — no grey-market, no parallel imports. Relevant when your ThinkSystem service contract requires original Lenovo parts for warranty or service compliance.
• Mexico Manufacturing Origin: Produced at Lenovo's MX facility under the same supply chain as the broader ThinkSystem ST550 platform.

Compatibility

This component is designated for the Lenovo ThinkSystem ST550 4U server. Verify your ST550 configuration and existing rack infrastructure before ordering — Lenovo's server components catalog includes complementary ST550 accessories. For broader rack mounting accessories and cable management options, confirm physical clearance against your rack's usable depth. If you are building out a full network infrastructure rack, cross-reference the ST550 component matrix in Lenovo's configuration guide to avoid ordering redundant or incompatible parts.

Frequently Asked Questions

The 7XH7A05903 is a lightweight ThinkSystem ST550 rack component at 1.50 lb — a weight and dimensional profile (17.90 × 7.60 × 2.70 in) that places it squarely in the rail kit or structural accessory category for the ST550 4U chassis. If you are mid-build on a ThinkSystem ST550 rack deployment and need a specific component to complete the installation, this part is factory-new and sourced through verified distribution.

Technical Highlights:

• 4U Rack Fit: At 17.90 inches long, this slots into standard 19-inch EIA rack cabinets with no cutting or modification — assuming your rack has adequate usable depth for the ST550 chassis footprint.
• 1.50 lb Net Weight: Light enough for single-technician handling during rack build-out; no lift assist required, which matters in space-constrained server rooms where maneuvering room is limited.
• Mexico Origin: Produced at Lenovo's MX manufacturing facility — same supply chain provenance as the broader ThinkSystem platform, relevant for procurement teams tracking country-of-origin for compliance or audit purposes.

Deployment Considerations:

• Available spec data is limited to physical attributes and platform designation. Before ordering, confirm the exact component function (rail, cable arm, bracket, etc.) against Lenovo's ST550 configuration matrix — part numbers in this family can be easy to confuse.
• If your ST550 is under an active Lenovo service contract, verify that this part number is the correct replacement or addition specified by Lenovo support — using an incorrect component number can complicate service claims.

The 7XH7A05903 is the right order for an ST550 rack build where you need a genuine Lenovo-sourced physical component to complete or maintain the installation to factory specification — particularly in managed data center environments where parts provenance is audited.
