When the AC power is turned on for the first time, the enduring power should turn on and the next voltage should develop.

Voltage Standby [SBY 5V], SBY 3.3V on some models] and the CNPSS connector for all voltages is enabled.

This requires power codes of power 1 and greater than 2 and come from PWB Dig Main CN-63. Approximately two minutes later, less than a quick start will activate, a relay click will actually be heard, and the CNPPS voltage will shut down the devices.

When quick start is enabled, electrical controls 1 and high, 2 and all of the above voltages remain on.
