USB5, USB6; USB7, USB8 Connentors and Serial Port Connector(COM2)
(optional)
Besides USB1,2,3,4 on the back panel, XV915 series of mainboards also have two head-
ers on board which may connect to front panel USB cable( optional ) to provide additional
four USB ports. The serial port COM2 is not available on the back panel. Therefore, we
provide a 9-pin header.
