Hot aisles are behind racks and cabinets. If there is an access floor, power distribution cables should be installed here under the access floor on the slab. Outlet in the equipment distribution areaĬabinets and racks shall be arranged in an alternating pattern, with fronts of cabinets/racks facing each other in a row to create “hot” and “cold” aisles.Ĭold aisles are in front of racks and cabinets.Zone outlet or consolidation point in the zone distribution area.Horizontal Cross-Connect (HC) in the telecommunication room, horizontal distribution area or main distribution area.Main Cross-Connect (MC) in the main distribution area.Cross-connect in the entrance room or main distribution area.The basic elements of the data center cabling system structure are the following: Informative annexes containing “best practices” and availability requirements Consider consolidating standardized and proprietary cabling into a single structured cabling system.Ĥ. When applying specific transmission protocols, consult standards, regulations, equipment vendors, and system service suppliers for applicability, limitations, and ancillary requirements. Some of these protocols impose distance restrictions that are shorter than those imposed by this standard. It facilitates the planning for data centers to occur earlier in the building development process (architectural, facilities, and IT).ĭata centers support a wide range of transmission protocols.
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.ģ. The purpose of this standard is to provide requirements and guidelines for the design and installation of a data center or computer room.Ģ. TIA/EIA 942 is the telecommunications infrastructure standard for data centers.
