Reset Switch (2-pin RST)
This 2-pin connector connects to the chassis-mounted reset switch for rebooting your
computer without turning your power switch off and on. This is a preferred method of
rebooting your system to prolong the life of your system’s power supply.
Hard Disk Activity LED (2-pin HDD_LED)
This connector supplies power to the chassis's HDD/IDE activity LED. Read and Write
activity by devices connected to the Primary or Secondary IDE connectors will cause the
front panel LED to light up.
Speaker Connector (4-pin SPEAKER)
There is one jumper over pin1 and pin2 (default setting) for the internal buzzer. If you want
to use the external case-mounted speaker instead of the internal buzzer, remove the jumper
and connect the speaker wire to the 4-pin connector.
ATX Power Switch / Soft Power Switch (2-pin PWR_SW)

the button once will switch the system between ON and SLEEP mode. The system power
LED shows the status of the system’s power.
System Power LED (3-pin PWR_LED)
