First of all, let's introduce the connection method of the key, the restart key, the power work indicator, the hard disk work indicator and the pre-buzzer. Please see the figure below. The
Connection method of switch, restart button and indicator light on the front panel of the chassis
The figure above shows the connection method of the front control button that comes with the motherboard specification. In the figure, we can clearly see the connection method of different pins. Among them PLED is the front power working working indicator pin of the chassis, there are "+" "-" two pins, corresponding to the PLED interface on the chassis; IDE_LED is the hard disk working indicator, also has "+" "-" two pins, Corresponds to the IDE_LED interface on the chassis; the PWRSW is the switch button on the chassis panel. It also has two pins. Since the switch key is realized by the two-pin short circuit, there is no "+" or "-" difference, as long as the chassis is corresponding to the PWRSW can be connected to the correct pin. RESET is a restart button. There is also no "+" or "-" division. The SPEAKER is a front-end buzzer, which is divided into "+" and "-" phases; ordinary speakers can take place regardless of how they are connected, but this is rather special. Since the "+" phase provides a +5V voltage value, we must install it properly to ensure that the buzzer sounds.
