P4V533-MX Front Panel Audio Connector

•System Power LED Lead (2-pin PWR LED)

This 2-1 pin connector connects to the system power LED. The LED lights up when you turn on the system power, and blinks when the system is in sleep mode.

•Hard disk activity LED (2-pin HD LED)

This 2-pin connector supplies power to the hard disk activity LED. The read and write activities of any device connected to the primary or secondary IDE connector cause this LED to light up.

•ATX Power Switch / Soft-Off Switch Lead (2-pin PWR BTN)

This connector connects a switch that controls the system power. Pressing the power switch turns the system between ON and SLEEP, or ON and SOFT OFF, depending on the BIOS or OS settings. Pressing the power switch while in the ON mode for more than 4 seconds turns the system OFF.

•Reset Switch Lead (2-pin RESET)

This 2-pin connector connects to the case-mounted reset switch for rebooting the system without turning off the system power.

Important Note:

A system buzzer (BUZZ1) is added to the motherboard. The system buzzer allows you to hear system warning beeps when a PC speaker is not available.
