3 Engineering Committee - Network Distribution Nodes - Project No. 3-0092. n Participants include: u Architecture & Engineering Firms u Consultants u End Users u Manufacturers n The Standard will become TIA-942. n To be submitted for approval by ANSI and CSA. Status of the Standard n 2nd draft released for industry ballot July 2003. n Draft posted to IEEE website n Ballot comments to be resolved October 2003. n Liaison with other standards organizations (IEEE, CENELEC, BICSI, ISO,ASHRE). n Liaison with data center industry organizations (7X24 Exchange,Uptime Institute). n Liaison with network and computer equipment manufacturers n Final approval expected sometime in 2004. Purpose of the Standard n Enabling planning for data centers to occur earlier in the building development process (architectural, facilities, and IT).

4 N Fill a void by providing standards for planning of data centers, computer rooms, server rooms, and similar spaces. n The Standard encompasses much more than just Telecommunications Infrastructure . n Close to half of the technical content deals with facility specifications. Purpose of the Standard n Specifications for data center Telecommunications cabling, pathways and spaces n Recommendations on media and distance and restrictions for data center applications over structured cabling system (TIA 232, TIA 561, T1, E1, T3, E3, 1 & 10 Gigabit Ethernet, Fibre Channel). n Establish a Standard for data center tiers to replace several proprietary standards . The TIA data center tier Standard is: A tool to evaluate existing data centers A tool to communicate design requirements Study Group: Telecommunications Cabling Infrastructure for Network Distribution Nodes Scope: Develop cabling topology, recognized media types, cabling requirements, and requirements for pathways & spaces for data centers n Cabling Design n Network Design n Facility Design n Informative annex: Provide best practices Design Elements: Cabling Design: n Copper and fiber cabling performance n Connectors, cables, distribution hardware n Cabling distances n Space management Facility Design.

5 NData center sizing nPower distribution methodologies nPathways and spaces nHVAC, security, operations, and administration. nFlexibility, scalability, reliability and space management Design Elements: Network Design: nSupport legacy systems nEnable rapid deployment of new technologies such as the emerging 10 Gb/s applications.
