• Abstract:

  This part of European Telecommunication Standard (ETS) 300 119 details requirements for miscellaneous racks and cabinets supplied unequipped. The miscellaneous racks/cabinets shall be used for housing telecommunication equipment forming part of a public telecommunication network installed either on the public telecommunication operators' sites or in the premises of operator's customers. The miscellaneous racks/cabinets shall be able to accommodate various equipments, e.g. subracks (see ETS 300 119-4 [3]) and shall have provision for doors or covers. Part 1 of this ETS (ETS 300 119-1 [1]) defines the meaning of rack or cabinet in the context of this ETS.

Overview

SIST ETS 300 119-3 E1:2006 defines the engineering requirements for miscellaneous racks and cabinets used for housing telecommunication equipment within public telecommunication networks. Published by the Slovenian Institute for Standardization (SIST) and aligned with European Telecommunications Standards Institute (ETSI) practices, this standard ensures that unequipped racks and cabinets facilitate interoperability, flexibility, and reliability in network infrastructure. It covers configurations intended for both network operator sites and customer premises, supporting the installation of subracks and various telecommunication components.

Key Topics

• Dimensional Requirements

  • Specifies standard heights (2200 mm), widths (600 mm), and depths (300 mm or 600 mm) for racks and cabinets.
  • Includes allowances for covers, doors, castors, and height adjustment for uneven floors.
  • Stresses compatibility between units from different suppliers to ensure seamless line-ups.

• Accessibility and Arrangement

  • Mandates front alignment for racks of different depths.
  • Supports configurations such as back-to-back placement or wall mounting for 300 mm depth units.
  • Ensures maintenance access is not obstructed by doors or covers.

• Floor and Structural Loading

  • Sets maximum permitted load per unit area (up to 20 kN/m²) for fully equipped racks.
  • Addresses point loading to prevent floor damage.
  • Requires calculation of cabling and overhead support weight to avoid exceeding building load limits.

• Cable Access and Management

  • Demands both top and bottom access points for routing cables via overhead structures or raised floors.
  • Specifies dedicated areas for cable passage, supporting efficient wiring and minimizing congestion.

• Packaging Dimensions

  • Limits shipping dimensions (maximum 2500 mm x 1200 mm x 900 mm) for ease of transport through standard lifts and hallways.

Applications

The requirements in SIST ETS 300 119-3 E1:2006 benefit a wide range of stakeholders in the telecommunications sector:

• Telecom Network Operators: Ensures the racks and cabinets they deploy meet unified European standards, promoting reliability and ease of maintenance.
• Equipment Manufacturers: Supports design and production of rack-mount solutions and subracks that are compatible with standardized enclosures.
• System Integrators and Installers: Facilitates planning of telecom rooms and equipment layout with predictable dimensions and load characteristics.
• End-User Enterprises: Offers assurance that telecom infrastructure delivered to customer premises meets recognized safety and interoperability standards.
• Building Managers and Architects: Simplifies mechanical planning in data centers, exchange sites, and customer locations through well-defined size and loading parameters.

Related Standards

SIST ETS 300 119-3 E1:2006 is part of a comprehensive series of equipment engineering standards supporting European telecommunication practices:

• SIST ETS 300 119-1: Introduction and terminology, which clarifies the context and definitions used throughout the series.
• SIST ETS 300 119-2: Engineering requirements for racks and cabinets, covering standard solutions.
• SIST ETS 300 119-4: Requirements for subracks within miscellaneous racks and cabinets, enabling modular and scalable designs.
• IEC 917-2: International standard underpinning coordination dimensions for the 25 mm equipment practice, referenced for mechanical interface consistency.

By following SIST ETS 300 119-3 E1:2006, organizations ensure compatibility, efficiency, and safety across Europe’s telecommunication infrastructure, supporting robust public and private network deployment.

Foreword
This European Telecommunication Standard (ETS) has been produced by the Equipment Engineering
(EE) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS is part 3 of a 4 part ETS aimed at setting out, on a common basis, the installation engineering
requirements for telecommunication practice, for housing equipment forming part of a public
telecommunications network.
Part 1 is a general introduction, and explains the terminology used, Part 2 specifies the engineering
requirements for racks and cabinets. This part, Part 3, specifies the engineering requirements for
miscellaneous racks and cabinets, Part 4 covers engineering requirements for subracks in miscellaneous
racks and cabinets.
This ETS applies to all telecommunication equipment forming part of the public telecommunications
network. The requirements for miscellaneous racks and cabinets which this part lays down are based on
the work of IEC Sub Committee 48D (see Annex B).
Illustrative figures are contained in Annex A.
