Chapter 4 - Jumper Settings

Power-on/ Clear CMOS

Power-on
JP5 is used to select the method of powering on the system. If you want the system to pow-
er-on whenever AC power comes in, set JP5 pins 3 and 5 to On. If you want to use the power
button, set pins 1 and 3 to On.
When using the JP5 "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, JP5 must be set to pins 3-5 and the "AC Power Lose" in CMOS is set
to "On".
