Engineering Notes

• Always maintain ≥20% PoE headroom for inrush current and future expansion.
• PoE++ (IEEE 802.3bt) supports up to 90W per port for high-power devices.
• Consider dedicated PoE switches for AV devices to isolate from IT traffic.
• Cable length affects delivered power — use shorter runs for high-wattage devices.
