Protecting 1Gb Ethernet From Lightning Strikes

+1 on the Ubiquiti surge protectors specifically designed for PoE gear
in mind (other brands like Cambium that are outdoor AP or camera
oriented may work equally as well). I would also recommend continuing to
isolate and protect as much as possible. For example, connecting your
outdoor PoE cameras or APs to dedicated PoE switches that connect back
to the core or aggregation switches via fiber. The PoE switches powering
the outdoor gear could be connected to power on dedicated PDUs that are
connected to dedicated circuits. I would imagine that PDUs that provide
surge protection or on-line/line-interactive UPS units would be
preferred over standby UPS units or PDUs that do not provide surge
protection. Would also be nice to keep spare parts on-site or
conveniently accessible, but not connected to power (e.g. focus on cold
spares before focusing on hot spares).
