Overview

SIST EN 300 119-7 V1.1.1:2015 is a European standard developed under the Environmental Engineering (EE) series, focusing on the engineering requirements for subracks used in harmonized racks and cabinets with extended features in telecommunication environments. Published by SIST, this standard provides specifications that ensure interoperability, safety, and streamlined installation of subracks within standardized network infrastructure. These requirements apply to subracks supplied fully assembled, unequipped, partially equipped, or fully equipped with plug-in units.

This standard is vital for telecommunications equipment manufacturers, network infrastructure designers, and system integrators aiming to achieve high compatibility across various rack systems while accommodating advanced cabling and seismic needs.

Key Topics

• Harmonized Subrack Dimensions
  Defines height, width, and depth for subracks, including allowances for plug-in units and accessories. Specifications enable consistent fitting in both 300 mm and 600 mm deep racks, allowing for flexible installations, including back-to-back mounting in 600 mm racks.

• Mounting Solutions
  Addresses depth adjustment of subrack mounting brackets, making bracket positioning adaptable and supporting both European and international practices such as the EIA rack standards.

• Accessibility
  Ensures that subracks for 300 mm deep racks require only front access, facilitating installations against walls or back-to-back configurations.

• Weight Specifications
  Sets maximum weight for unequipped subracks (18 kg) for safe handling. Also includes guidance on providing equipped subrack weights for floor load calculations in data centers and telecom facilities.

• Extended Cabling Space
  Specifies additional front space to accommodate optical and electrical I/O cabling, improving cable management and accessibility.

• Seismic Considerations
  Aims to harmonize with international seismic requirements by aligning the mounting planes and rack depths to support earthquake-resistant installations.

Applications

• Telecommunication Networks
  Designed for public telecommunication networks and data center environments, ensuring that all housed subracks are compatible with harmonized racks and cabinets featuring extended mechanical and cable management features.

• Equipment Manufacturer Guidance
  Provides manufacturers with standardized design and assembly requirements, reducing customization overhead and promoting the development of interoperable plug-in units and systems.

• System Integration
  Streamlines the installation and maintenance process for system integrators managing different equipment from various suppliers, lowering installation complexity and ensuring consistent cable routing and access.

• Facility Planning and Safety
  Supports facility planners in meeting seismic, loading, and accessibility requirements, essential factors for safe, long-term operation in critical telecom and IT infrastructure.

Foreword
This draft European Standard (EN) has been produced by ETSI Technical Committee Environmental Engineering (EE),
and is now submitted for the combined Public Enquiry and Vote phase of the ETSI standards EN Approval Procedure.
The present document is part 7 of a multi-part deliverable aimed at setting out, on a common basis, the engineering
requirements for telecommunication practice, for housing equipment forming part of a public telecommunications
network. ETSI EN 300 119-1 [i.1] is a general introduction and explains the terminology used. ETSI EN 300 119-2 [i.2]
specifies the engineering requirements for racks and cabinets and ETSI EN 300 119-3 [i.3] specifies the engineering
requirements for miscellaneous racks and cabinets. ETSI EN 300 119-5 [i.5] covers the preferred thermal management
solutions for subracks, racks/cabinets and miscellaneous racks/cabinets installed indoors in restricted access locations,
for the removal of heat dissipated by one or more subracks in an rack complying to the requirements of this multi-part
standard. The present document specifies the engineering requirements for subracks mounted in harmonized racks and
cabinets with extended features.
The present document applies to all telecommunications equipment forming part of the public telecommunications
network.
The present document, ETSI EN 300 119-7, is defining extension to the existing parts of the standard to harmonize
dimensions and to extend rack installation capabilities.
These extended features are:
• mounting bracket depth adjustment only on subrack level (as normally done in many other standardized
equipment practices; see 19 inches)
• common position of mounting brackets for both 300 mm and 600 mm depth
• recessed subrack mounting plane compared to ETSI EN 300 119-3 [i.3] and ETSI EN 300 119-4 [i.4] to allow
more room for cable management and better cable access from front/rear aisle
• design subrack mounting plane in a manner so that not only 600 mm deep rack is a earthquake proof design
but also the 300 mm rack (600 mm: ~7 inches deep upright; 300 mm ~3,5 inches deep upright; commonality
with EIA rack standard for SNBF)
• make ETSI mounting principle similar to SNBF (5 inches deep upright) which is used in USA
telecommunication offices to gain more commonality for international markets
• define extra front side cabling space for accommodating optical and electrical I/O cables
