B75H2-M USER MANUAL

5. CASE: Chassis Intrusion Detect Header

This detects if the chassis cover has been removed. This function needs a chassis
equipped with instrusion detection switch and needs to be enabled in BIOS.

The motherboard has two USB 2.0 headers supporting three USB 2.0 ports (one 10-
pin USB 2.0 header supports additional two USB 2.0 ports and one 5-pin USB 2.0
header supports additional one USB 2.0 port).

 

Additionally, some computer cases

have USB ports at the front of the case. If you have this kind of case, use auxiliary USB
connector to connect the front-mounted ports to the motherboard.

6 & 7. F_USB1~2: Front Panel USB 2.0 headers

Please make sure that the USB cable has the same pin assignment as indi-
cated above. A different pin assignment may cause damage or system hang-
up.
