Unverified面板AP的PoE网线一根同时承载数据和供电，交换机到AP的网线长度需在100米内，超长会同时导致断电和断网，布线时注意实际线缆走位余量77% similarUnverifiedPoE供电交换机选购必看总功率预算(PoE Budget)，而非端口数：8口PoE若总功率仅60W，实际只能带满2-3个AP(802.3at每口需30W)，需按设备数×单设备功率×1.3余量计算75% similarUnverifiedPoE交换机需注意单口供电标准（PoE 15.4W/PoE+ 30W/PoE++ 60W）和整机供电总功率预算，接入大功率AP或摄像头时供电总功率不足会导致设备掉线74% similarUnverified监控系统选PoE交换机时，需确认单口输出功率与总供电预算：单个IPC约需5-15W，PoE+(802.3at)单口30W，需注意标称总功率往往低于'端口数×单口最大'，8口PoE整机预算通常仅60-130W73% similar
