The motherboard has USB ports installed on the rear edge I/O port array.

Locate the F_USB1/F_USB2 header on the motherboard.
2.
Plug the bracket cable onto the F_USB1/F_USB2 header.

Remove a slot cover from one of the expansion slots on the system
chassis. Install an extension bracket in the opening. Secure the
extension bracket to the chassis with a screw.
