I had a power outage overnight, UPS kept the switch running until it died. When it came back on the switch wouldn’t boot, other devices on the UPS are fine.

The fans spin up to 100%, and the power LED is blinking green. That is the only activity I get. The documention says that means it’s booting which usually only takes a minute, but I’ve let it sit for a long time with no results. I get no output from USB or Console port.

What can I do to bring the switch back up?
