4.1.1.1.4 Power Switch Header
Pins 6 and 8 can be connected to a front panel momentary-contact power switch. The switch must
pull the SW_ON# pin to ground for at least 50 ms to signal the power supply to switch on or off (the
time requirement is due to internal debounce circuitry on the board). At least two seconds must
pass before the power supply will recognize another on/off signal.
4.1.1.2 BIOS Security Jumper
CAUTION
Do not move a jumper with the power on. Always turn off the power and unplug the power cord
from the computer before changing a jumper setting. Otherwise, the board could be damaged.
Figure 9 shows the location of the BIOS Security Jumper. The 3-pin jumper determines the BIOS
Security program’s mode.
