The Telecommunications Industry Association (TIA) ANSI/TIA-942-A Telecommunications Infrastructure Standard for Data Centers[1] is an American National Standard (ANS) that specifies the minimum requirements for structured cabling work defined in TIA/EIA-568, and is often cited by companies such as ADC Telecommunications[2] and Cisco Systems.[3] The standard was updated with an addendum ANSI/TIA-942-A-1 in April 2013 from the TR-42.1 Commercial Building Telecommunications Cabling Subcommittee, the formulating group that oversees development of the standard.[4] The Telecommunications Industry Association does not offer certification programs or certify compliance to TIA standards. In many cases, there are other organizations and consultants that can provide those services. However, TIA does not certify these organizations or consultants. This is similar to how organizations like ISO operate where they rely on Certification Bodies to ensure that there is oversight over organizations performing such activities.

On October 15, 2015, the TIA TR-42.1 Subcommittee voted to start the revision process of ANSI/TIA-942-A. The standard will undergo updates during 2016. The new version of ANSI/TIA-942 which will be labelled as ANSI/TIA-942-B is slated for release in July 2017.

The ANSI/TIA-942-A specification references private and public domain data center requirements for applications and procedures such as:

  • Network architecture
  • Electrical design
  • File storage, backup and archiving
  • System redundancy
  • Network access control and security
  • Database management
  • Web hosting
  • Application hosting
  • Content distribution
  • Environmental control
  • Protection against physical hazards (fire, flood, windstorm)
  • Power management
