I live in Florida, and it’s been an extremely active storm season with lots of electrical storms near my house. I have had two close strikes about a week apart, and have lost a modem and a switch between the two, despite having a surge protector. I am wondering there’s anything I might be able to do to mitigate losses from strikes. I am looking at adding a UPS, and also running an earth ground to the network rack, but haven’t found anything by way of a “best practices”. Any help would be much appreciated.
In AZ here with monsoon & associated thunder storms; I unplug the dsl line from modem and don’t worry about ac mains power but do turn everything off. I saw a local news broadcast after one storm where a strike excavated the isp coax line and a 2" strip of asphalt that was above it all the way across the residential street.
Everything was plugged into a Startech RKPW081915.
It is still reporting surge protection, though I’m not sure I trust it. I have been doing some digging, and there are some other potential culprits. There’s a powered coax splitting in my junction box that was NOT grounded as it should have been. I also have a few POE cameras that run through the attic. That cable is not shielded, but I didn’t think it needed to be as it’s all within the structure. Apparently “induced” strikes are a thing, which I plan to mitigate in the near a future with some ethernet grounding blocks such as these.
