Jumpers Setup - ASROCK iEP-7020E Series User Manual

4.2 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 a jumper cap is placed on these 2
pins.
Chassis Intrusion Header
(2-pin CI1)
(see p. 60, No. 6)
This motherboard supports CASE OPEN detection feature that detects if the chassis cover has
been removed. This feature requires a chassis with chassis intrusion detection design.
Digital Input/Output Default Value Setting
(3-pin JGPIO_SET1)
(see p. 60, No. 7)
The header is used for GPIO default value setting for either pull high or pull low.
Pulling the header to a high/low value means the voltage is anchored to VCC/GND, in a
stable, non-floating state.
Clear CMOS Jumpers
(3-pin CLRMOS1)
(see p. 60, No. 8)
Note: CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system pa-
rameters 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 CLRMOS1 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 updat-
ing 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 date, time and user default profile
will be cleared only if the CMOS battery is removed.
