Changes in the jumpers settings may only be implemented by appropriately trained staff.
The illustration shows how jumpers are setup. When the jumper cap is placed on pins, the
jumper is “Short”. If no j
umper
cap is placed on pins, the
jumper is “Open”. The illustration shows a 3

Jumper N°2 of the motherboard
CLEAR CMOS
CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the system parameters to default setup, please
turn off the computer and unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper
cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However, please do not clear the CMOS right after you
update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system
first, and then shut it down before you do the clear-CMOS action. Please be noted that the password, date, time, user
default profile and MAC address will be cleared only if the CMOS battery is removed.
Default PSR1 factory setting: 1-2
