H87E-ITX/ac 2.5 Jumpers Setup The illustration shows how jumpers are setup. When the jumper cap is placed on the pins, the jumper is "Short". If no jumper cap is placed on the pins, the jumper is "Open". Clear CMOS Jumper (CLRCMOS1) (see p.1, No. 14) 2-pin Jumper Short: Clear CMOS Open: Default CLRCMOS1 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 the pins on CLRCMOS1 for 3 seconds. Please remember to remove the jumper cap after clearing the CMOS. 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. 1. The Clear CMOS Switch has the same function as the Clear CMOS jumper. 2. If you clear the CMOS, the case open may be detected. Please adjust the BIOS option "Clear Status" to clear the record of previous chassis intrusion status. English 23

Jumpers Setup
°e illustration shows how jumpers are setup. When the jumper cap is placed on
the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper is
“Open”.
Clear CMOS Jumper
(CLRCMOS1)
(see p.1, No. 14)
Short: Clear CMOS
Open: Default
CLRCMOS1 allows you to clear the data in CMOS. °e 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
the pins on CLRCMOS1 for 3 seconds. Please remember to remove the jumper
cap aſter clearing the CMOS. 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.
2-pin Jumper
1.
°e Clear CMOS Switch has the same function as the Clear CMOS jumper.
2. If you clear the CMOS, the case open may be detected. Please adjust the BIOS option “Clear
Status” to clear the record of previous chassis intrusion status.
