Dongya network cabinets typically follow standard 19-inch rack specifications with customizable heights, widths, and depths to suit various IT equipment and installation needs.

Standard Dimensions

Most network cabinets, including those from Dongya, adhere to the EIA-310 standard, which specifies a 19-inch internal mounting width for rack-mounted equipment . Heights are measured in rack units (U), where 1U = 1.75 inches (44.45 mm). Common heights include:

• 42U (approx. 73.5 inches tall)
• 48U (approx. 84 inches tall)
• Compact options: 22U–27U for smaller installations Depths vary depending on equipment and airflow requirements, with typical options including 24″, 36″, 42″, 48″, and 59″. Wider outer dimensions (e.g., 24″–31.5″) allow for cable management and ventilation . Dongya also offers customized sizes to meet specific client requirements, including non-standard widths or depths for specialized equipment .

Key Features Affecting Size Selection

• Ventilation: Mesh or perforated doors provide 60–80% open area for airflow, critical for high-density server setups .
• Cable Management: Cabinets include vertical managers, brush plates, and finger ducts, which may require additional internal depth.
• Security: Lockable doors and removable side panels can slightly affect usable internal space.
• Mobility and Stability: Optional castor wheels or leveling feet may influence overall footprint.
• Power Distribution: Built-in or optional PDUs may require extra space for installation and airflow .

Customization Options

Dongya Engineering provides custom network cabinets for clients, including Fortune 500 companies, allowing adjustments in:

• Rack height (U)
• Depth and width
• Door type (hinged, sliding, mesh, or solid)
• Additional accessories like shelves, rails, and PDUs

Practical Considerations

When selecting a Dongya network cabinet, consider:

1. Total equipment height in U to ensure sufficient rack space.
2. Depth for cable routing and airflow.
3. Environmental factors such as dust, moisture, or EMI, which may require hybrid or filtered panels.
4. Future expansion, ensuring modularity for additional equipment . By combining standard 19-inch rack dimensions with Dongya's customization capabilities, you can select a network cabinet that balances space efficiency, cooling, security, and scalability for your IT infrastructure.
