A powered device can be powered using a primary local power source and a secondary PoE power source. To enable consistent behavior by the powered device, a controlled power fallback state can be defined that would ensure limited functionality in the powered device upon a failure of the primary local power source. For example, the limited functionality could include a communication channel to the switch, diagnostic circuitry, etc."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power over ethernet powered device with power fallback states","description":"A power over Ethernet (PoE) powered device with power fallback states.
