Engine start up error
• The /ENGRDY signal is not detected even after the specified time
has elapsed after turning the main power on or restoring from
energy saver mode.
• The /ENGRDY signal is detected, but it is negated at an unexpected
occasion*.
* Expected negation occurs when turning the power off, switching
to the energy saver mode (after the engine automatically goes off),
and rebooting the machine.
• The engine board does not start up.
• The connection between the controller board and engine board is
faulty.
Check the connection between the engine board and the controller
board.
• If this problem always occurs, replace the engine board. If the
problem persists, consider replacing the controller board or other
boards between them.
• If this problem occasionally occurs, multiple causes are to be
considered, such as the software, engine board, controller board,
and PSU.
