  • Causes of lightning strikes on PoE switches

    Causes of lightning strikes on PoE switches

    PoE powering is often used indoors because outdoor cabling requires unshielded network cables and causes PoE switches to be damaged by lightning strikes. By sending data and electrical power over a single cable, PoE simplifies installations and powers devices such as IP cameras, wireless access points and VoIP phones. But with great convenience comes vulnerability. Another key factor is that PoE combines two things on the same pairs: high-speed differential data signals and DC power delivery. It suddenly stops supplying power to the APs after a period of time. Feb 28 2020 14:35:50 hwPoePowerOff_active(l):CID=0x0-alarmID=0x08012266;PD powered off.
