I lost the ports on some indoor devices when a neighbor's house was struck by lightning. The damaged ports were all running off a PoE switch I had spare to use but didn't need the PoE feature. A PC connected to a non-PoE port of the same switch was completely fine. PoE subverts the normal galvanic isolation of UTP Ethernet so beware of using it on important hardware.
