Cabling Changes: Recognizes single balanced twisted-pair cable for horizontal cabling and recommends a minimum of two optical fibers for backbone cabling . Tier III (Concurrently Maintainable): Now requires that you

• Tier III (Concurrently Maintainable): Now requires that you can replace a liquid cooling pump without shutting down any racks.
• Tier IV (Fault Tolerant): New rules for "Cyber-Physical Systems" – your BMS (Building Management System) must have redundant network paths separate from the IT network.

The ANSI/TIA-942-C standard, published in May 2024, is the latest revision of the globally recognized Telecommunications Infrastructure Standard for Data Centers. It provides a comprehensive framework for designing and building resilient, scalable, and efficient data centers, ranging from small edge facilities to massive hyperscale environments. Key Scope and Infrastructure Pillars
