Chapter 2: Installation
This is a PICO-ITX (3.9-in x 2.8-in) form factor motherboard. 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 off 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.

13
2.3 Installation of Memory Module (SO-DIMM)
SOM-P102 provides one 204-pin DDR3 (Double Data Rate 3) SO-DIMM slot.
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.

14
2.4 Expansion Slots (M.2 and mini-PCIe/mini-SATA
Slots)
There is 1 M.2 slot and 1 mini-PCIe/mini-SATA slot on this motherboard.
M.2 slot:
M2_1 (Key-E M.2 slot) is used for type 2230 for WiFi + BT Module.
mini-PCIe/mini-SATA slot:
MINI_SATA1 (mini-PCIe/mini-SATA slot; full size) is used for PCI Ex-
press mini cards or mSATA cards.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off 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.

15
2.5 Onboard Headers and Connectors
1. 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!
2. Jumper Guide link: http://asrock.pc.cdn.bitgravity.com/Manual/
Jumper/SOM-P102.pdf
Item 13~16: The pin denition of these headers depend on each M/B
manufacturer, please double-check the pin denition before testing.
SATA3 Connector This Serial ATA3
(SATA3_1: see p.8, No. 1) (SATA3) 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 Header There is one USB 2.0
(9-pin USB2_4_5) headers on this motherboard.
(see p.8 No. 3)
System Panel Header This header accommodates
(9-pin PANEL1) several system front panel
(see p.9 No. 15) 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 off 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 off when the system is in S3/S4 sleep
state or powered off (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 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 assign-ments are
matched correctly.

the chassis must support HDA to function correctly. Please follow the
instruction in our manual and chassis manual to install your system.
2. If you use AC’97 audio panel, please install it to the front panel audio
header as below:
A. Connect Mic_IN (MIC) to MIC2_L.
B. Connect Audio_R (RIN) to OUT2_R and Audio_L (LIN) to OUT2_L.
C. Connect Ground (GND) to Ground (GND).
