After last thunderstorm I've got couple of hAP ac and they're currently in the box for recycling. I connected couple of them to the power the they all behave the same - PWR & SFP led are lit up, there's a beep at the beginning but nothing after (no dobule-beep). They're not booting, there's nothing visually burned on the board, they don't smell any more horrible that before
Also there's no response to reset button.
What's funny while we replaced them with power supplies the ones which were connected to them seems to be alive.
Any debug steps I can try or they're scrap?
