If the voltage was too high or had spikes it could certainly have done that. Kinda the reverse of the Netonix problem.

That's what fixed it for sure. The AP is sitting here in the lab and doing gigabit for 3 days now, happily. The POE and surge card are in the trash. I'm wondering if it's possible the POE fried all of those surge cards on Saturday/Sunday/Monday/Tuesday. If that's possible?

I presume that means the POE power supply. So try a new one. I am probably not understanding the situation.

After several cards I have to imagine it's the POE or the AP. We replaced those two at the same time. Does it make sense the POE was doing something weird to fry them or more sense the AP was pulling too many amps? AP seems perfectly fine in the office for 36 hours, so I'm inclined to believe it's the POE.

The one I took down this morning looks perfectly clean and I can't get pins 7/8 through it. At this point I'm thinking the (AC) POE is the cause of all our issues (Cambium, so that pair is positive 24v and data).

That will remove any water. Need to make sure there is no corrosion. Wash out the jacks extra good too. If they have not had too large of a surge, they are totally self resetting. From: Josh Luthman Sent: Tuesday, September 11, 2018 7:25 AM To: AFMUG Subject: [AFMUG] Surge suppression failure gigE APC HV There's a cause and I'm pretty confident it's not the cards themselves. This weekend an AP started having eth link issues. Look at it and the card/rj45 is full of water. Replaced the line. Problem returns about 12 hours later. I plug in my continuity tester and pin 7 blinks quickly and fades away. Headed up the tower now for a new AP and already did a new Poe (no power until AP replaced). Is it possible the Poe/AP are damaging the surge card? We've gone through 5-6 cards since Saturday, and I thought it was all water related. It stopped raining on Sunday after card 3 + new line. Any other ideas? Can I wait a minute and reuse the dry cards, are they self resetting (I tried power cycling the POE for 5 seconds with no change) after a length of time?
