POE goes over pins 4,5,7,8
I do not think the suggested Ethernet surge protectors would have helped Roscoe.
The spike that killed his equipment probably came over the other conductors
As you well know, if a direct lightning strike occurs, all bets are off. The best we can hope for is to protect against HV/HF spikes either entering the property via power , data, antenna or communications wiring. It is not enough to protect only at the point of entry to the premises, secondary protection is required in the building: certainly at subpanels, but also at point-of-use for critical and expensive gear/appliances/etc. This is needed because a close-by strike will mean induced voltages everywhere.
To that end, a variety of suppressors (including power line and coaxial) should be employed at point-of-entry along with a second set of suppressors right where cables connect to anything you cringe at buying again: air conditioner controls, laundry and kitchen appliances, everything networked via copper, televisions, etc.
The links I sent have a large variety of gear available. Not just POE and Ethernet protectors, unless I sent the wrong links. And that is always a possibility, just like lightning striking.
