Racks

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

Type	Functional Features	Application Examples
19" Open Frame Rack	Lightweight, ventilated structure with adjustable mounting	Data center network switches
23" Cabinet Rack	Legacy standard with enclosed design	Telecom legacy equipment
Wall-Mount Rack	Space-saving vertical mounting	Branch office servers
4-Post Server Rack	Reinforced load-bearing for heavy equipment	Enterprise data centers
Portable Rack	Mobile solutions with casters and shock absorption	Field deployment systems

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

Parameter	Value Range	Importance
Rack Unit (RU)	1U=1.75" (44.45mm)	Standardized height measurement
Load Capacity	50-2000kg	Equipment safety and structural integrity
Material Thickness	1.2-6.0mm	Vibration resistance and durability
Cooling Efficiency	0.5-5.0m /s	Thermal management performance
Seismic Rating	0.2-2.0g	Earthquake protection compliance

5. Application Fields

Data Centers: Server clusters, storage arrays
