Press the reset switch to restart the computer if the _S computer freezes and fails to perform a normal restart. •• CI (Chassis Intrusion Header): Connects to the chassis intrusion switch/sen_sor on the chassis that can detect if the chBasSs_is cover has been removed. This function requires a chassis wiBth a chassis intrusion switch/sensor. B •• NC: No connection. The front panel design may differ by chassis. A front panel module mainly consists of power switch, reset switch, power LED, hard drive activity LED, speaker and etc. When connecting your chassis front panel module to this header, make sure the wire assignments and the pin assignments are matched correctly. S B_ B 8) F_AUDIO (Front Panel Audio Header) The front panel audio header supports Intel High Definition audio (HD) and AC'97 audio. You may connect your chassis front panel audio module to this header. Make sure the wire assignments of the module connector match the pin assignments of the_ mSotherboard header. Incorrect connection between the module connector and the motherboard header will make the device unable to work or even damage it.
