These jumpers are used to select the power of the USB ports. Selecting 5VSB will allow you to use the Wake-On-USB Key- board function.

On the G4H875-N and G4H875-C system boards, JP3 is for setting USB 1-4 that are at the rear I/O panel. USB 3-4 are not present at the rear I/O panel of the G4H875-B system board, therefore JP3 on this board is for setting USB 1-2 only.

On the G4H875-B system board, JP4 is for setting the external ports connected to J12 (USB 3-4 connector).

BIOS Setting:

“USB KB WakeUp From S3(S4)” in the Power Management Setup submenu of the BIOS must be set to Enabled. Refer to chapter 3 for more information.

Important:

If you are using the Wake-On-USB Keyboard function for 2

USB ports, the 5VSB power source of your power supply must support 2A.

If you are using the Wake-On-USB Keyboard function for 3

or more USB ports, the 5VSB power source of your power supply must support 2A.
