Installation Notices for the M.2 and SATA Connectors: Due to the limited number of lanes provided by the Chipset, the availability of the SATA connectors may be affected by the type of devices installed in the M2A_32G connector. The M2A_32G connector shares bandwidth with the SATA3 0 connector. Refer to the following table for details.

The system reports system startup status by issuing a beep code. One single short beep will be heard if no problem is detected at system startup. •• HD (Hard Drive Activity LED): Connects to the hard drive activity LED on the chassis front panel. The LED is on when the hard drive is reading or writing data. •• RES (Reset Switch): _S Connects to the reset switch on the chassis front panel. Press the reset switch to restart the computer if the computer freezes and fails to perform a normal restart. •• CI (Chassis Intrusion Header): Connects to the chassis intrusion swit_cBh/sensor on the chassis that can detect ifBthSBe_ chassis cover has been removed. This function requires a chassis with a chassis intrusion switch/sensor. •• 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 thSe Bw_ire assignments and the pin assignments are matched correctly.
