Jumper Settings

Power-on Select

JP6 is used to select the method of powering on the system. If you want the
system to power-on whenever AC power comes in, set JP6 pins 2 and 3 to On. If
you want to use the power button, set pins 1 and 2 to On.

When using the JP6 “Power On” feature to power the system back on after a
power failure occurs, the system may not power on if the power lost is resumed
within 5 seconds (power flicker).

Note:
In order to ensure that power is resumed after a power failure that re-
covers within a 5 second period, JP6 must be set to pins 2-3 and the
“PWRON After PWR-Fail” in CMOS is set to “On”.
