2.7.23 Front Panel LEDs and Switches
HD-LED: Primary/Secondary IDE LED
This LED will light when the hard drive is being accessed.
ATX-SW: ATX Power Switch
Depending on the setting in the BIOS setup, this switch is a “dual
function power button” that will allow your system to enter the Soft-
Off or Suspend mode. Refer to “Soft-Off By PWR-BTTN” in the
Power Management Setup (Chapter 3).
RESET: Reset Switch
This switch allows you to reboot without having to power off the
system thus prolonging the life of the power supply or system.
SPEAKER: Speaker Connector
This connects to the speaker installed in the system chassis.
KEYLOCK: Power/Standby LED and Keylock Connector
Use pins 15 to 17 to connect to the Power/Standby LED. When the
system’s power is on, this LED will light. When the system is in the
S1 (POS - Power On Suspend) state, it will blink every second.
When the system is in the S3 (STR - Suspend To RAM) state, it will
blink every 4 seconds.
Note:
If a system did not boot-up and the Power/Standby LED did
not light after it was powered-on, it may indicate that the CPU
or memory module was not installed properly. Please make
sure they are properly inserted into their corresponding socket.
