USB Headers

This motherboard contains eight (8) USB 2.0

ports that are exposed on the rear panel of the chassis

(Figure 2). The motherboard also contains two 10-pin

internal header connectors onboard that can be used to

connect an optional external bracket containing four

USB 2.0 ports.

1. Secure the bracket to either the front or rear panel

of your chassis (not all chassis are equipped with the

front panel option).

2. Connect the end of the cable to the USB 2.0

header on the motherboard.
