This jumper allows you to connect PCI/PCI-Express slots to the System Management Bus. The
default setting is open to disable the connection.
USB wake-up (JPUSB1/JPUSB2)
Use the JPUSB jumpers to enable the function of system wake-up via USB devices. This allows
you to "wake-up" the system by pressing a key on the USB keyboard or by clicking the USB
mouse.
JPUSB1 is for back panel USB ports 1/2/3/4/5/6.
JPUSB2 is for front panel USB ports 7/8/9/10 and front accessible USB ports: 11/12.
Notes:
ƒ
Before allowing the system to go into standby mode, be sure to remove all USB devices
from USB ports that have been disabled.
ƒ
The JPUSB jumper settings must match the USB wake-up settings in the BIOS.
Watch dog (JWD)
Watch dog is a system monitor that can reboot the system when a software application hangs.
Close Pins 1-2 to reset the system if an application hangs. Close Pins 2-3 to generate a non-
maskable interrupt signal for the application that hangs. Watch dog must also be enabled in the
BIOS. If this jumper is set to Disabled, the Watch Dog Settings listed in the BIOS will be ignored.
