2. P-LED(Power LED Connector):

The power indicator LED shows the system's power status. It is important to pay attention to the correct cable and pin orientation (i.e., not to reverse the order of these two connectors.)

3. G-BTN/G-LED(Green Button Switch/LED Connector):

Some ATX cases provide a Green button switch, which is used to put the system in Suspend mode. In Suspend mode, the power supply to the system is reduced to a trickle, the CPU clock is stopped, and the CPU core is in its minimum power state. The system is activated whenever the keyboard or mouse is touched. The system resumes in different ways as defined by Power Management Setup screen in BIOS.

For Green LED connector please refer to Section 2.6 CBOX™ 2

4. RESET (System Reset Switch Connector):

This connector should be connected to the reset switch on the front panel of the system case. The reset switch allows you to restart the system without turning the power off.

5. SPEAKER (Speaker Connector):

This 4-pin connector connects to the case-mounted speaker.

6. HD-LED(IDE Activity LED Connector):

The IDE activity LED lights up whenever the system reads/writes to the IDE devices.

FD1 (Floppy Connector)

The motherboard provides a standard floppy disk drive connector that supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types, use this connector to connect 34 pins of Floppy.
