Chapter 1: Product introduction

1.11 Jumpers

This section describes and illustrates the jumpers on the motherboard.

1. USB device wake-up (3-pin USBPW12, USBPW34, USBPW56)

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 USBPW12 jumper is for the rear USB port. USBPW34 and USBPW56 are

for the internal USB header that you can connect to 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.
