Chapter 1: Motherboard Information

1.9 Jumpers

This section describes and illustrates the jumpers on the motherboard.

1. USB device wake-up (3-pin USBPWR_12,USBPWR_34,USBPWR_56)

Set these jumpers to +5V to wake up the computer from S1 sleep mode

(CPU stopped, DRAM refreshed, system running in low power mode) using

the connected USB devices. Set to +5VSB to wake up from S3 sleep mode

(no power to CPU, DRAM in slow refresh, power supply in reduced power

mode). Both jumpers are set to pins 1-2 (+5V) by default because not all

computers have the appropriate power supply to support this feature.

The USBPWR_12 and USBPWR_34 jumpers are for the rear USB port.

USBPWR_56 is for the internal USB header that you can connect to the front

USB ports.

This feature requires a power supply that can provide at least 2A on

the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the

system does not power up.

The total current consumed must NOT exceed the power supply

capability (+5VSB) whether under normal condition or in sleep mode.
