2.9.5 Power LED & K/b Lock (JFP3/PWR_LED & KEY LOCK)
(JFP3/PWR_LED and KEY LOCK) is a five-pin connector for the Power-On LED and
Key Lock function. Refer to Appendix B for detailed information regarding the pin
assignments. The Power LED cable should be connected to Pins 1-3. The key lock
button cable should be connected to Pins 4 and 5.
Three power supply connection modes exist. The first is the ATX power mode, where
the system is powered on/off by momentarily pressing the power button. The second
is the AT power mode, where the system is powered on/off using the power supply
switch. The third is another AT power mode that involves the front panel power
switch. The status differences indicated by the power LED are listed in the following
