ANSI/TIA/EIA-942标准

The Purpose of ANSI/TIA/EIA-942
Telecommunications Infrastructure Standard for Data Centers
• The purpose of this standard is to provide requirements and guidelines
for the design and installation of a data center or computer room.
• It is intended for designers who need a comprehensive understanding
of the data center design including the facility planning, the cabling
system, and the network design.
• It facilitates the planning for data centers to occur earlier in the building
development process (architectural, facilities, and IT).
Data centers support a wide range of transmission protocols. Some of these
protocols impose distance restrictions that are shorter than those imposed
by this standard. When applying specific transmission protocols, consult
standards, regulations, equipment vendors, and system service suppliers
for applicability, limitations, and ancillary requirements. Consider consolidating
standardized and proprietary cabling into a single structured cabling system.
The Standard Specifies:
• Cabling design
• Network design
• Facilities design
• Informative annexes containing “best practices”
and availability requirements
• Spaces
• Pathways
• Racks/cabinets
