8) M2P (M.2 Socket 3 Connector)
The M.2 connectors support M.2 SATA SSDs or M.2 PCIe SSDs and support RAID conguration. Please
note that an M.2 PCIe SSD cannot be used to create a RAID set with a SATA hard drive. To create a RAID
array with an M.2 PCIe SSD, you must set up the conguration in UEFI BIOS mode. Refer to Chapter 3,
"Conguring a RAID Set," for instructions on conguring a RAID array.
Follow the steps below to correctly install an M.2 SSD in the M.2 connector.
Step 1:
Use a screwdriver to unfasten the screw on the heatsink and then remove the heatsink rst. If you want
to install an M.2 2242 or 2260 SSD, get a screw and a standoff from the included M.2 screw kit and follow
the pictures below to install.
1. 2242 size:
Fasten standoff A to the "42"
hole on the PCH heatsink.
2. 2260 size:
Fasten standoff B to the "60"
hole on the motherboard.

Step 2:
Slide the M.2 SSD into the connector at an angle.
Step 3:
Press the M.2 SSD down and then secure it with the screw. Replace the heatsink and secure it to the
original hole.
Standoff A Standoff B
If you want to install an M.2 2260 or 2280 SSD, be sure not to fasten standoff A to the heatsink, or
the M.2 SSD may be damaged.
Select the proper hole for the M.2 SSD to be installed and refasten the screw and standoff.

17) CLR_CMOS (Clear CMOS Jumper)
Use this jumper to clear the BIOS conguration and reset the CMOS values to factory defaults. To clear
the CMOS values, use a metal object like a screwdriver to touch the two pins for a few seconds.
•Always turn off your computer and unplug the power cord from the power outlet before clearing
the CMOS values.
•After system restart, go to BIOS Setup to load factory defaults (select Load Optimized Defaults) or
manually congure the BIOS settings (refer to Chapter 2, "BIOS Setup," for BIOS congurations).
Open: Normal
Short: Clear CMOS Values
18) 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. Unplug the the battery cable from the battery cable header and wait for one minute.
3. Plug in the battery cable.
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. Damage to your devices may occur 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.
