Case Open Warning Jumper: CASE OPEN
This connector is used to notify the user when the computer case has been previously opened. To
configure this functionality, your computer case must be equipped with a “ case open” cable which
you need to attach to the CASE OPEN jumper. Also, you must enable CASE OPEN warning
functionality in the BIOS setup utility. When your computer case is opened, your system will display
alert messages upon boot up. Note that your computer case must be equipped with a “case open”
cable.
Front Serial Port Header: COM2
This mainboard supports a front serial header. To use this header, you can install a back panel bracket
(optional) with a wire extending to this header. You can then attach your serial device to the serial
port on the bracket.
