Clear CMOS data Jumper
If the CMOS data becomes corrupted or you
forgot the supervisor or user password,
clear the CMOS data to reconfigure the
system back to the default values stored in
the ROM BIOS.
To CMOS Clear data, please follow the steps below.
1. Turn off the system.
2. Change the jumper from “1-2” to “2-3” position
for a few seconds.
3. Replace the jumper on to the “1-2” position.
4. Turn on the system and hold down the <Del>
key to enter BIOS setup.

JCPU_FAN / JSYS_FAN:
CPU/Chassis Fan Power Connectors
JCPU_FAN: The CPU must be kept cool by using a
heatsink with fan assembly.
JSYS_FAN: The chassis fan will provide adequate
airflow throughout the chassis to prevent overheating the CPU.
