3.7 Jumpers This section describes and illustrates the jumpers on the motherboard. 1. USB device wake-up (3-pin USB_PWR12, USB_PWR34, USB_PWR56) 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). The USB_PWR12 jumper is for the rear USB ports. The USB_PWR34 and USB_PWR56 jumpers are for the internal USB headers that connect to the front USB ports and USB-CF slot. NOTES This feature requires a power supply that can provide at least 1A 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.

Jumpers
This section describes and illustrates the jumpers on the motherboard.
1.
USB device wake-up (3-pin USB_PWR12, USB_PWR34,
USB_PWR56)
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).
The USB_PWR12 jumper is for the rear USB ports. The
USB_PWR34 and USB_PWR56 jumpers are for the internal USB
headers that connect to the front USB ports and USB-CF slot.
NOTES
This feature requires a power supply that can provide at least 1A 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.
