Jumpers Setup

The illustration shows how jumpers are

setup. When the jumper cap is placed on

pins, the jumper is “Short”. If no jumper cap

is placed on pins, the jumper is “Open”. The

illustration shows a 3-pin jumper whose pin1

and pin2 are “Short” when jumper cap is

placed on these 2 pins.

PS2_USB_PWR1

Short pin2, pin3 to enable

(see p.8,  No. 1)

+5VSB (standby) for PS/2 or

USB wake up events.

Note: To select +5VSB, it requires 2 Amp and higher standby current provided by

power  supply.

JL1 / JR1 Jumper

(see p.8,  No. 27)

Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel

audio connectors can work.

Clear CMOS Jumper

(CLRTC1)

(see p.8,  No. 14)

Note: CLRTC1 allows you to clear the data in CMOS. The data in CMOS includes

system setup information such as system password, date, time, and system

setup parameters. To clear and reset the system parameters to default setup,

please turn off the computer and unplug the power cord, then use a jumper

cap to short pin2 and pin3 on CLRTC1 for 3 seconds. Please remember to put

the jumper cap back to the default setting (short pin1 and pin2) after clearing

the CMOS.
