4.3Jumpers

This section describes and illustrates the jumpers on the motherboard.

1 . USB device wake-up (3-pin USBPWR12, USBPWR34, USBPWR56)

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, S4, and S5 sleep mode (no power to CPU, DRAM in slow refresh, power supply in reduced power mode).

The USBPWR12 jumper is for the rear USB ports. The USBPWR34 and USBPWR56 jumpers are for the internal USB connectors that you can connect to additional USB ports.

•The motherboard provides 0.5A for each USB port and 1.5A for all devices requiring +5VSB power. To use the USB device wake-up feature, the total +5VSB power for all connected devices must not exceed 1.5A.

•The total current consumed must NOT exceed the power supply capability (+5VSB), whether under normal condition or in sleep mode.

•Make sure to set the jumpers to +5VSB if you want to wake up the system from S3, S4, and S5 sleep mode.
