2.7.20 Front Panel Connectors
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 PWRBTN” 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 sys-
tem.
SPEAKER: Speaker Connector
This connects to the speaker installed in the system chassis.
PWR-LED: 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.
