Chapter 2: Installation
This is a 111.76 x 116.84 mm form factor motherboard. Before you install the moth-
erboard, 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)
UTX-115 provides two 204-pin DDR3 (Double Data Rate 3) SO-DIMM slots, which
supports dual channel DDR3L SDRAM only.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM
matches the break on the slot.
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.
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 and SIM Sockets)
There are 2 M.2 sockets and 1 SIM socket on this motherboard.
SIM Socket:
1 x SIM socket connected to M.2 Key B.
M.2 Sockets:
1 x M.2 (KEY E, 2230) socket supports PCIe x1 and USB2.0 for Wire-
less.
1 x M.2 (KEY B, 3042/3052) socket supports USB 2.0+ SATA/PCIex2 +
SIM for 4G.

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
(CLRCMOS1)
(see p.8, No. 13)
Note: CLRCMOS1 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 CLRCMOS1 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 prole and MAC
address will be cleared only if the CMOS battery is removed.

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!

System Panel Header This header accommodates
(9-pin PANEL1) several system front panel
(see p.8, No. 6) 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/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 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.
LPC Header This connector supports a
(19-pin LPC1) Trusted Platform Module (LPC)
(see p.8, No. 11) system, which can
securely store keys, digital
certicates, passwords, and
data. A LPC system also helps
enhance network security,
protects digital identities, and
ensures platform integrity.
