Overview

SIST EN 300 119-2 V2.1.1:2006 is a European standard specifying engineering requirements for racks and cabinets used in telecommunication environments. Developed by the Slovenian Institute for Standardization (SIST) in alignment with ETSI specifications, the standard outlines practical criteria for the design, installation, and integration of racks and cabinets that house telecommunication equipment in public networks. These requirements ensure compatibility, structural integrity, accessibility, and compliance with electromagnetic compatibility (EMC) directives for equipment deployed in operator sites or customer premises.

Key Topics

1. Coordination Dimensions

• Racks and cabinets addressed in this standard include all covers, feet, and external parts in their dimensions.
• Permitted width options: 150 mm, 300 mm, 600 mm, or 900 mm.
• Depth must be 300 mm or 600 mm, with the inclusion of doors, handles, connectors, and other protruding elements.
• Height regulation allows configurations up to 2,200 mm for telecommunication centers or as agreed for customer locations.

2. Accessibility and Layout

• Design ensures all essential operations are possible without restrictions from doors or covers.
• Allows front-only access for 300 mm depth units, supporting back-to-back or wall installation.
• Ensures alignment of different depth cabinets within the same row, promoting straightforward line-up and integration.

3. Cable Access Solutions

• Cable routing provisions via the top and bottom of the rack/cabinet.
• Supports over-structure or under-floor cable management configurations.
• Facilitates direct cable connections between adjacent racks/cabinets in row arrangements.

4. Structural and Floor Loading

• Defines maximum permissible static and dynamic loading, with strict limits on weight per unit area to protect infrastructure.
• Point loading restrictions prevent floor damage, supporting safe installation in diverse facility types.
• Packaged racks/cabinets must conform to specific maximum dimensions for ease of transportation and handling.

5. EMC and Electrostatic Discharge

• Compliance with European EMC Directive (Council Directive 89/336/EEC) is required.
• Supports selection of equipment and materials in accordance with emerging European and international standards addressing electromagnetic phenomena.

Applications

This standard is critical for:

• Telecommunication Operators: Ensuring that housing infrastructure for network equipment meets European requirements for safety, accessibility, and reliability.
• Data Centers: Integrating network and telecom cabinets that maximize space and promote efficient cable management.
• System Integrators and Installers: Supporting planning, procurement, and compliant deployment of racks and cabinets within public telecom facilities and enterprise environments.
• Manufacturers: Designing and producing compliant racks and cabinets for European and global markets, with a focus on interoperability and EMC performance.
• Facility Managers: Validating that installations meet load and access standards, supporting the long-term durability and flexibility of networked spaces.

Related Standards

• EN 300 119-1: Introduction and terminology for racks and cabinets (foundation for this series).
• EN 300 119-3: Engineering requirements for miscellaneous racks and cabinets.
• EN 300 119-4: Engineering requirements for subracks in miscellaneous racks and cabinets.
• EN 300 119-5: Guidelines for thermal management in telecom racks/cabinets.
• IEC 60917-2: Modular order for the development of mechanical structures - reference for coordination dimensions.

SIST EN 300 119-2 V2.1.1:2006 is a key standard for implementing robust, maintainable, and compliant telecommunication rack and cabinet infrastructures across Europe, supporting efficient network equipment practice and operational reliability.
