3/4) CPU_FAN/SYS_FAN (Fan Headers)

The motherboard has a 4-pin CPU fan header (CPU_FAN) and a 4-pin system fan header (SYS_FAN). Each fan header supplies a +12V power voltage and possesses a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed with color-coded power connector wires. A red power connector wire indicates a positive connection and requires a +12V voltage. The black connector wire is the ground wire. The motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.

• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating. Overheating may result in damage to the CPU or the system may hang.

• These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.

5) FDD (Floppy Disk Drive Connector)

This connector is used to connect a floppy disk drive. The types of floppy disk drives supported are: 360 KB, 720 KB, 1.2 MB, 1.44 MB, and 2.88 MB. Before connecting a floppy disk drive, be sure to locate pin 1 of the connector and the floppy disk drive cable. The pin 1 of the cable is typically designated by a stripe of different color.

Hardware Installation- 23 -

6) IDE (IDE Connector)

The IDE connector supports up to two IDE devices such as hard drives and optical drives. Before attaching the IDE cable, locate the foolproof groove on the connector. If you wish to connect two IDE devices, remember to set the jumpers and the cabling according to the role of the IDE devices (for example, master or slave). (For information about configuring master/slave settings for the IDE devices, read the instructions from the device manufacturers.)

9) BATTERY

The battery provides power to keep the values (such as BIOS configurations, date, and time information) in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low level, or the CMOS values may not be accurate or may be lost.

You may clear the CMOS values by removing the battery:

1. Turn off your computer and unplug the power cord.

2. Gently remove the battery from the battery holder and wait for one minute.

(Or use a metal object like a screwdriver to touch the positive and

negative terminals of the battery holder, making them short for 5 seconds.)

3. Replace the battery.

4. Plug in the power cord and restart your computer.

• Always turn off your computer and unplug the power cord before replacing the battery.

• Replace the battery with an equivalent one. Danger of explosion if the battery is replaced

with an incorrect model.

• Contact the place of purchase or local dealer if you are not able to replace the battery by yourself or uncertain about the battery model.

• When installing the battery, note the orientation of the positive side (+) and the negative side (-) of the battery (the positive side should face up).

• Used batteries must be handled in accordance with local environmental regulations.
