Chapter 2: Installation
Before you install the motherboard, study the conguration of your chassis to ensure
that the motherboard ts into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
Do not over-tighten the screws! Doing so may damage the motherboard.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity,
NEVER place your motherboard directly on the carpet or the like. Also
remember to use a grounded wrist strap or touch a safety grounded object
before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded antistatic pad or
in the bag that comes with the component.
Before you install or remove any component, ensure that the power is
switched o󰀨 or the power cord is detached from the power supply.
Failure to do so may cause severe damage to the motherboard, peripherals,
and/or components.

12
2.3 Installation of Memory Modules (SO-DIMM)
This motherboard rovides two 204-pin DDR4 (Double Data Rate 4) SO-DIMM slots.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM
matches the break on the slot.
1. The SO-DIMM only ts in one correct orientation. It will cause permanent damage
to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at
incorrect orientation.
2. Please do not intermix di󰀨erent voltage SO-DIMMs on this motherboard.
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clips at both
ends fully snap back in place and the SO-DIMM is properly seated.

13
2.4 Expansion Slots (M.2 Slots)
There are 2 M.2 slots on this motherboard.
M.2 for SSD: 1 x M.2 (KEY M, 2242/2260/2280) with PCIe x1 and SATA3 for SSD.
* M.2 Key M 2280(Supported by bracket)
M.2 for Wi-Fi: 1 x M.2 (Key E, 2230) with PCIe x1 and USB 2.0 for Wireless.

2.5 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 jumper cap
is placed on these 2 pins.
Clear CMOS Jumper 1-2: Auto Clear (PWR OFF)
(3-pin CLRMOS1) 2-3: Clear CMOS
(see p.8, No. 3)
Note: CLRMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn o󰀨 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 nish updating the BIOS, you must boot up
the system rst, and then shut it down before you do the clear-CMOS action.
Please be noted that the date, time, user default prole and MAC address will
be cleared only if the CMOS battery is removed.
CLRMOS1 allows you to clear the data in CMOS automatically when AC pow-
er on. The data in CMOS includes system setup information such as system
password, date, time, and system setup parameters. To clear and reset the
system parameters to default setup, please turn o󰀨 the computer and unplug
the power cord, then use a jumper cap to short the pins on CLRMOS1.
SIO_AT1 Open: ATX Mode (Default)
(2-pin SIO_AT1) Short: AT Mode

2.6 Onboard Headers and Connectors
Onboard headers and connectors are NOT jumpers. Do NOT place
jumper caps over these headers and connectors. Placing jumper caps
over the headers and connectors will cause permanent damage of the
motherboard!
SATA3 Port This Serial ATA3 (SATA3)
(SATA3_1: see p.8, No. 7) connector supports SATA data
cables for internal storage
devices. The current SATA3
interface allows up to 6.0 Gb/s
data transfer rate.
USB 2.0 Connector There is one USB 2.0
(9-pin USB2_6_7) connector on this
(see p.8, No. 5) motherboard.
COM Port Header (RS232/422/485)
(9-pin COM1: see p.8, No. 6)
* This motherboard supports RS232/422/485 on COM1 port. Please
refer to below table for the pin denition. In addition, COM1 port
(RS232/422/485) can be adjusted in BIOS setup utility > Advanced
Screen > Super IO Conguration. You may refer to our user manual for
details.

System Panel Header This header accommodates
(9-pin PANEL1) several system front panel
(see p.8, No. 9) functions.
Connect the power switch, reset switch and system status indicator on the
chassis to this header according to the pin assignments below. Note the
positive and negative pins before connecting the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may congure
the way to turn o󰀨 your system using the power switch.
RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset
switch to restart the computer if the computer freezes and fails to perform a
normal restart.
PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The LED
is on when the system is operating. The LED keeps blinking when the sys-
tem is in S1 sleep state. The LED is o󰀨 when the system is in S4 sleep
state or powered o󰀨 (S5).
HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The LED
is on when the hard drive is reading or writing data.
The front panel design may di󰀨er by chassis. A front panel module mainly
consists of power switch, reset switch, power LED, hard drive activity LED,
speaker and etc. When connecting your chassis front panel module to this
header, make sure the wire assignments and the pin assign-ments are
matched correctly.
