TIA-942, Standard for Data Centers has been updated

The Telecommunications Industry Association (TIA) have updated their standard TIA 942 and made it available to purchase through IHS. 
The standard contains 118 pages and costs $464 and is available as a hardcopy or pdf file.
The TIA 942 standard specifies the minimum requirements for telecommunications infrastructure of data centres and computer rooms including single tenant enterprise data centres and multi-tenant Internet hosting data centres. The topology proposed in this document is intended to be applicable to any size data centre.

The major modifications in ANSI/TIA-942-A from ANSI/TIA-942 include:
  • ANSI/TIA-942-A has been harmonized with the TIA-568-C series including the topology, terms, and environmental classifications described in ANSI/TIA-568-C.0, and component specifications in ANSI/TIA-568-C.2 and ANSI/TIA-568-C.3.
  • The content of the addenda - ANSI/TIA-942-1 and ANSI/TIA-942-2 - has been incorporated into this Standard and these two documents will be superseded at the time of publication of ANSI/TIA-942-A.
  • Category 3 and category 5e are no longer recognised for horizontal cabling. Recognised balanced twisted-pair cable types for horizontal cabling are category 6 or category 6A.
  • Recognised multimode optical fibre cable for horizontal and backbone cabling has been changed to OM3 and OM4 850 nm laser-optimized 50/125 m multimode optical fibre cable.
  • The Intermediate Distribution Area (IDA) has been added to the data center topology.
  • Recommendations for energy efficiency have been added.
  • The terms 'Equipment Outlet' (EO) and 'External Network Interface' (ENI) from ISO/IEC 337 24764 have been added.
