Foreword In today’s rapidly evolving world, headlines often highlight climate change and the rise of Artificial Intelligence (AI), but few address the environmental challenges posed by AI infrastructure, particularly its soaring energy demands. These demands can be addressed with advancements in power generation, storage and distribution. For two decades, Cisco has pioneered Power over Ethernet (PoE), setting new standards for efficient and reliable power delivery in network and building infrastructure. The development of Class 4 Fault Managed Power (FMP) represents another giant leap in power distribution across multiple environments. Established in 2023 under National Electric Code (NEC) Article 726 and UL1400, FMP offers efficient power delivery, simplified infrastructure, improved resiliency, and support for ever-higher power demands. From intelligent buildings to data centers, FMP can offer cheaper, safer, smarter and more efficient electrical distribution solutions. FMP backhaul, PoE last-mile, combined with on-site generation and storage, these are the advancements that can help to empower consumers with data-driven insights and granular control, enabling near-real-time load optimization and full utilization of renewable energy sources while reducing waste and lowering upfront-cost. As innovation continues, the synergy between these emerging technologies can help shape a more sustainable and resilient energy future. Here at Cisco, we are committed to fostering education, awareness, and practical applications for the next generation of power delivery ecosystems.
“At Cisco, we view Fault Managed Power (FMP) as a transformative technology that extends well beyond traditional power distribution methodologies.”
