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 ( 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.
