Chapter 2 Installation
is is a NUC (4.09-in x 4.02-in x 1.4-in, 10.4 cm x 10.2 cm x 3.6 cm) form factor
motherboard. Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.
2.1 Screw Holes
Place screws into the holes to secure the motherboard to the chassis.
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.
5. Heatsink (e thermal solution of whole system needs to be designed additionally.)
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.
Do not over-tighten the screws! Doing so may damage the motherboard.
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.

NUC-N97
2.3 Installation of Memory Modules
NUC-N97 provides one 260-pin DDR4 (Double Data Rate 4) SO-DIMM slot, and supports
Single Channel Memory Technology.
Step 1. Align a SO-DIMM on the slot such that the notch on the SO-DIMM matches the
break on the slot.
1. e 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 incor-
rect orientation.
2. Please do not intermix dierent voltage SO-DIMM on this motherboard.
Step 2. Firmly insert the SO-DIMM into the slot until the retaining clip at both ends fully
snaps back in place and the SO-DIMM is properly seated.

2.4 Expansion Slots
ere are 2 M.2 sockets on this motherboard.
M.2 for SSD: 1 x M.2 (KEYM, 2242/2260/2280) with PCIe Gen3 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, USB 2.0

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.

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. e LED is on when the
system is operating. e LED keeps blinking when the system is in S3 sleep state. e 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. e LED is on when the
hard drive is reading or writing data.
The front panel design may differ 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 assignments are matched correctly.
