JP2 functionality is broken in rev1. In rev2, "JP2 Warm Start" should do what you want: * When you apply AC power, the board turns on. * It will turn off if: 1) a software shutdown command is received, or, 2) if a hardware fault occurs, or, 3) the front panel power button is pressed. * To power it back on, press the front panel power button or cycle the AC power.
"JP1 Force On" forces power on whenever AC is applied, bypassing all onboard safety monitoring, the front panel power switch etc. No matter what, it will turn on if there's AC power plugged in. This is your only option on rev 1 boards.
