PoE, power and thermal considerations: With multi-mode PoE (up to higher wattages) now common for IoT, lighting, and building systems, 568.1-E stresses cable bundling effects, temperature rise, and de-rating—arguing for installer awareness of ampacity and thermal derating to avoid reduced performance or safety issues.
