PWR_OK Signal

With the PWR_OK signal on the feature connector (X35), the user can control the SBC's start-up process. When this signal is set to low, the SBC
is kept in reset until the PWR_OK signal is asserted.
When the signal is asserted (set to high), it indicates to the SBC that the supplied power is stable. The SBC then begins its onboard power-up
sequence.

Power Status LEDs

The conga-IA5 provides two LED signals (FP_LED+ and P_LED-) on pins 2 and 4 of the front panel connector X39. The signals indicate the
different power states of the conga-IA5. Possible states and corresponding activity of the LEDs are shown below:
