Look at the English on the line interface, the power switch is a signal to stimulate the ATX power supply to the motherboard and other devices, the power switch on the chassis panel is used to turn on/off the power (soft shutdown). When connecting the power switch cable, first from the chassis panel cable to find the two-pin plug labeled "Power SW", respectively, white and brown two colors, and then inserted in the motherboard marked with "PWR SW" or "PWR and plug it into the pin labeled "PWR SW" or "PWR" on the motherboard, no need to pay attention to the positive and negative connections. The reset switch is used to restart the computer. When connecting the reset switch cable, first from the chassis panel cable to find marked "Reset SW" two-pin plug, respectively, white and blue two colors, and then inserted in the motherboard marked "Reset" or "RST "on the motherboard marked with" Reset "or" RST "on the pins can be, do not need to pay attention to the positive and negative connection. The power indicator can indicate whether the motherboard is currently powered on. Connect the power indicator cable, first from the chassis panel cable to find a three-pin plug labeled "Power LED", the middle of a line is vacant, the two ends of the white and green colors, and then inserted in the motherboard marked with "PWR LED" or "P LED". P LED" on the motherboard pin labeled "PWR LED" or "P LED". Since the power indicator is a light-emitting diode, the connection is directional. Some motherboards will be labeled "P LED +" and "P LED -", we need to connect the green end of the corresponding P LED + pin, the white wire connected to the P LED - pin can be. The hard disk indicator can indicate the working status of the hard disk, this light is blinking, indicating that the hard disk is being accessed. When connecting the hard disk indicator cable, first from the chassis panel cable to find marked "H.D.D. LED" two-pin plug, respectively, white and red two colors, and then inserted in the motherboard marked with "HDD LED" or "IDE LED". "IDE LED" on the motherboard. The connection of the HDD LED is also directional. Some motherboards are labeled "HDD LED+" and "HDD LED-", we need to connect the red end to the HDD LED+ pin and the white wire to the HDD LED- pin. The speaker is a small speaker on the main chassis, which can provide some power-on self-test error signal ringing work. When connecting the HDD LED cable, first find the four-pin plug labeled "Speaker" from inside the chassis, the middle two wires are vacant, and the two ends are red and black respectively, and then plug it into the motherboard labeled "Speaker" or "SPK". "SPK" on the motherboard. Speakers are theoretically differentiated into positive and negative poles, with red plugging in the positive level and black plugging in the negative level, but in practice they can be reversed to produce sound. --From the forum
