Chapter 2: Installation
This is a Mini-ITX form factor (6.7” x 6.7”, 17.0 x 17.0 cm) motherboard. Before you
install the motherboard, study the conguration of your chassis to ensure that the
motherboard ts into it.
motherboard. Failure to do so may cause physical injuries to you and
damages to motherboard components.
Make sure to unplug the power cord before installing or removing the
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.
20
2.3 Installation of Memory Modules (SO-DIMM)
This motherboard provides two 260-pin DDR4 (Double Data Rate 4) SO-DIMM
slots.
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 dierent voltage SO-DIMMs on this motherboard.

2.4 Expansion Slots
There is 1 mini-PCIe slot, 2 M.2 sockets and 1 PCI Express slot on this mother-
board.
mini-PCIe slot:
MINI_PCIE1 (mini-PCIe slot; half/full size) is used for PCI Express mini
cards.
M.2 sockets:
1 x M.2 (M2_2) (Key E, 2230) with PCIe x1, CNVI and USB2.0 for
Wireless.
1x M.2 (M2_1) (Key M, 2242/2260/2280) with shared SATA3 for SSD
PCIE slot:
PCIE1 (PCIE x16 slot) is used for PCI Express x16 lane width cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched o or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screws for later use.
Step 4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

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 illus-
tration shows a 3-pin jumper whose pin1 and
pin2 are “Short” when jumper cap is placed on
these 2 pins.

2-3 : Clear CMOS
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 password,
date, time, user default prole and MAC address will be cleared only if the CMOS
battery is removed.

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 congure
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/S3 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 dier 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.
