Hi all,

Now that we're heading into the stormy summer season, I'm reviewing our standard deployment specs for outdoor edge devices—specifically long-run IP cameras and gate controllers on dedicated metal poles.

In the past, we've used standard inline PoE surge protectors, but we still see occasional port blowouts on the switch side after heavy lightning storms nearby, even when the pole itself is properly grounded.

I’m curious about your real-world setups:

1. Do you automatically budget for surge suppression at both ends (at the device and before entering the patch panel)?

2. Are there specific brands you've found to actually survive a near-miss, or do you treat them as sacrificial items that you replace annually?

Just trying to cut down on warranty truck rolls this summer. Would love to hear what's working for you guys in the field.

I dunno, I see switches blow ports just because an electrician flicks power on off a few times

Put in different model and no problem, I wonder if it's are voltage problem aswell , but mostly they were tplink

Dlink seemed to survive and so do many cheap Chinese versions , which ususally die completely when they do

That’s an interesting take on the power flicking, @al-yeti. I hadn't closely tracked the on/off cycles, but now that you mention it, transient voltage spikes from messy electrical cutovers make total sense for blowing those sensitive port components.

It's funny about TP-Link vs D-Link and the cheaper alternatives. I've noticed similar patterns—some of the generic units seem to have beefier component tolerances on the front end, or they just act as a hard fuse and die completely to save the upstream link, whereas others let the spike leak through and ruin the specific switch port.

Are you guys adding any simple power conditioners or miniature UPS units at the head-end to smooth out those dirty power flips before it hits the PoE switch, or is that just overkill for smaller multi-site deployments?
