A conversation-style interview discussing Class 4 Fault Managed Power (FMP), a new power distribution technology that enables touch-safe high-voltage DC delivery up to 400V. Combined with direct liquid cooling, it can reduce data center energy costs by 75% or deliver 2.3x more compute for the same energy. Unlike traditional AC wiring requiring licensed electricians and steel conduit, FMP uses standard cabling practices similar to Power over Ethernet, allowing network engineers to install it safely. The technology is being brought to market through a partnership between Cisco, NTT, and Panduit, with free training available. It addresses growing data center energy demands driven by AI workloads, AC-to-DC conversion losses (3-6 hops in typical data centers), and community pushback against power-hungry facilities.
