Sure, you can also wash them with 90% isopropyl alcohol.  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.

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?
