I would begin by referencing the grounding section here: https://www.blm.gov/sites/blm.gov/files/Lands_ROW_Motorola_R56_2005_manual.pdf Of utmost importance is that everything is bonded to the same potential. This means that if they have stuff on a roof, outdoor antennas or APs, whatever, it ground needs to be bonded to the building's AC electrical service entrance ground, ufer ground if one exists, and so forth. This is probably the lowest cost ohm meter that is suitable for real world use: https://www.amazon.com/Extech-382252-Ground-Resistance-Tester/dp/B00390G3YA The WISP community has over the past twenty years of painful experience learned to use a combination of high quality ethernet surge protectors (previously mentioned McCown Tech suppressors or their competitors) and comprehensive grounding.

I'm working with a client site that has been hit twice, very close by lightening. I did lots of electrical work/upgrades/grounding but now I want to focus on protecting Ethernet connections between core switching/other devices that can't be migrated to fiber optic. I was looking for surge protection devices for Ethernet but have never shopped for anything like this before. Was wondering if anyone has deployed a solution? They don't have a large presence on site (I have been moving all of their core stuff to AWS) but they still have core networking / connectivity and PoE cameras / APs around the property. Since migrating their onsite servers/infra to the cloud, now their connectivity is even more important. This is a small site, maybe about 200 switch ports, but I would only need to protect maybe 12 core ones. but would be something I could use in the future with larger deployments. it's just a 1Gbe network BTW. Hope someone with more experience can help make hardware recommendations? Thanks in advance. - Javier
