The ANSI/TIA-942-C standard, released in May 2024, is the latest evolution of the global benchmark for data center infrastructure. It supersedes the previous "B" version (2017) to address modern demands like Artificial Intelligence (AI), edge computing, and sustainability. Data Center Infrastructure Report: ANSI/TIA-942-C 1. Executive Summary
Chapter 9: Power and Grounding
- Dual-Corded loads: Clarified that for Tier III, a server with two power supplies must have each cord on a separate PDU and separate UPS.
- Battery storage: New restrictions on Lithium-Ion battery placement (must be in a 2-hour fire-rated room if > 50kWh).

ANSI/TIA-942-C (Telecommunications Infrastructure Standard for Data Centers) was officially released in The ANSI/TIA-942-C standard, released in May 2024 ,
Key Features of TIA-942-C
1. Recognition of New Technologies The "C" revision modernized the standard to include technologies that have become standard since the "B" revision: Dual-Corded loads: Clarified that for Tier III, a
- Higher Power Densities – Explicit design guidance for racks up to 30 kW and pathways for 100 kW+ (AI/HPC clusters).
- Liquid Cooling Integration – Direct-to-chip and immersion cooling requirements now part of the baseline standard, not an addendum.
- Sustainability Metrics – First TIA-942 revision to include PUE (Power Usage Effectiveness), WUE (Water Usage Effectiveness), and embodied carbon guidance.
- Topology Updates – Simplified star topology plus an approved “collapsed backbone” for smaller edge data centers.
- Cybersecurity Overlays – Links to TIA-942-B’s telecom infrastructure but adds references to NIST SP 800-82 for OT security.
- Fiber & Cabling – Added support for 400 GbE and 800 GbE using OS2 single-mode and OM5 wideband multimode.
