+5VSB_MB Chassis Signal GND 10. Chassis Intrusion header (4-1 pin CHASSIS) This header is for a chassis-mounted intrusion detection sensor or switch. Connect one end of the chassis intrusion sensor or switch cable to this connector. The chassis intrusion sensor or switch sends a high-level signal to this connector when a chassis component is removed or replaced. The signal is then generated as a chassis intrusion event. CHASSIS 11. Clear CMOS header The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM in the CMOS, which contains the date, time, system passwords, and system setup parameters. CLRTC +3V_BAT GND To erase the RTC RAM: PIN 1 1. Turn OFF the computer and unplug the power cord. 2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds. 3. Plug the power cord and turn ON the computer. 4. Hold down the key during the boot process and enter BIOS setup to re-enter data. DO NOT short-circuit the pins except when clearing the RTC RAM. Short-circuiting or placing a jumper cap will cause system boot failure! If the steps above do not help, remove the onboard button cell battery and short the two pins again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the button cell battery. RXD DTR DSR CTS 12. COM Port header This header is for a serial (COM) port. Connect the serial port module cable to COM this header, then install the module to a slot opening at the back of the system chassis. PIN 1 The COM port module is purchased separately. DCD TXD GND RTS RI 13. Front Panel Audio header This header is for a chassis-mounted front panel audio I/O module that supports HD audio standard. Connect one end of the front panel audio I/O module cable to this header. AAFP AGND NC SENSE1_RETUR SENSE2_RETUR • We recommend that you connect a high-definition front panel audio module to this header to avail of the motherboard's high-definition audio capability. • If you want to connect a high-definition front panel audio module to this header, set the Front Panel Type item in the BIOS Setup to [HD Audio]. By default, this header is set to [HD Audio]. PORT1 L PORT1 R PORT2 R SENSE_SEND PORT2 L HD-audio-compliant pin definition 1-4 Chapter 1: Product Introduction
