1. Overview

Racks are standardized frame systems designed to house and organize electronic equipment, providing mechanical support, cable management, and environmental protection. Defined by international standards (e.g., EIA-310), they ensure interoperability across industries. Their importance lies in enabling scalable infrastructure for data centers, telecommunications, industrial automation, and mission-critical systems.

2. Main Types and Functional Classification

3. Structure and Components

Typical racks feature:

• Vertical mounting rails with tapped holes (10-32 UNF)
• Adjustable horizontal supports
• Integrated cable management (vertical/horizontal)
• Material options: Steel (2-4mm thickness), Aluminum alloys
• Accessories: PDU units, fan trays, security locks

4. Key Technical Specifications

5. Application Fields

• Data Centers: Server clusters, storage arrays
• Telecommunications: 5G base stations, fiber distribution hubs
