7) SATA3_0/1/2/3/4/5 (SATA 6Gb/s Connectors)
The SATA connectors conform to SATA 6Gb/s standard and are compatible with SATA 3Gb/s and SATA
1.5Gb/s standard. Each SATA connector supports a single SATA device. The AMD SB950 South Bridge
supports RAID 0, RAID 1, RAID 5, RAID 10, and JBOD. Refer to Chapter 5, "Conguring SATA Hard
Drive(s)," for instructions on conguring a RAID array.
A RAID 0 or RAID 1 conguration requires at least two hard
drives. If more than two hard drives are to be used, the total
number of hard drives must be an even number.
A RAID 5 conguration requires at least three hard drives.
(The total number of hard drives ••does not have to be an
even number.)
A RAID 10 conguration requires four hard drives.
Please connect the L-shaped end of
the SATA cable to your SATA hard
drive.
8) BAT (Battery)
The battery provides power to keep the values (such as BIOS congurations, 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.
