(*1) RMTSHTDN and GENDI use the same contact (switched by the RAS software setting).
RMTPWRON and GENDI2 use the same contact (switched by the jumper pin setting). For details,
see "6.6 Enabling the Remote Power On Function".
(*2) When you use an RMTPWRON function, make sure no noise is added to the external contact.
If the contact is closed for 15 ms or more during the soft power off mode due to noise or other
reasons, the power may be turned on unexpectedly. As a side note, while the OS or BIOS is running
after power on, the RMTPWRON function is disabled and the contact can be used as a GENDI2
input.
