Lightning damaging Switches PoE modules

[jmprats]

Hi, I have problems with the network devices every time there is a thunderstorm . Always suffer the PoE module of some switches, also some indoor access points and some network cards from PC's or printers.

It seems closed to the circuit Switch PoE - Indoor Access Point or Network devices
What is the explanation?
What can I do to avoid it?

Can the lightning enter through the indoor network cabling?

Or maybe through some network device not connected to UPS?

Thanks

Hi @jmprats

It is perfectly possible. You need revise your electric circuits and install lightning rod properly.
