Re: Protecting 1Gb Ethernet From Lightning Strikes

[Blake Hudson <blake () ispn net>]

+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).
