I've been a bit lazy about setting up an APU2C4 I bought last year. Anyway, a few days ago I went ahead and installed pfSense on it, but hadn't got around to configuring it.
It was sitting plugged-in for the last 3-4 days and then today I noticed it seems completely dead. None of the LEDs are lighting up, no output on the serial port.
Any ideas on how to troubleshoot this ?
