I have an outdoor shaded box with a USW Flex in it. That one box kills them quickly. I doubt it gets over 110-120F, so the root cause is a bit of a mystery.

I have an outdoor shaded box with a USW Flex in it. That one box kills them quickly. I doubt it gets over 110-120F, so the root cause is a bit of a mystery. Any suggestions for a more robust model?
The box has a long PoE run and then it redistributes out the PoE to 3-4 other PoE devices. The wattage is well within spec, but they usually drop to 100MBit from 1GBit a few months before permanently failing, so there could be some sort of signal integrity problem or over-driving of the phy, etc.
I'm kind of considering trying a Flex Mini, since at least they're cheaper. (The box is waterproof.)
- xethos 3y agoMaybe I'm wrong, so confirm by opening your previously-killed equipment and looking for corrosion, but: > The box is waterproof to me just means any water (or humidity) that's in the box when you seal it, stays in the box. Maybe add a dessicant that you can replace every few months?
- woleium 3y agoUsed to do this with a tin can full of potassium permanganate (potassium manganate 7 in newspeak). Just heat it till it’s white then put it back after it’s turned purple from absorbing water (I.e. recycle it) Not even sure if you can buy it now, it’s useful for nefarious things. Used to be in survival kits, it’s a fire starter, disinfectant and mouthwash too.
