The university I worked at used ITW Linx surge arrestors for years, never had any issues.

Never had issues with the CAT6-75 model, worked perfect with Cisco equipment. We also used the CAT6-LAN models where POE was not needed, as they clamp to 16v vs the 75v of the CAT6-75 model.

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
