WARNING!
Federal Communications Commission (FCC) Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance with instructions
contained in this manual, may cause harmful interference to radio and television communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- REORIENT OR RELOCATE THE RECEIVING ANTENNA
- INCREASE THE SEPARATION BETWEEN THE EQUIPMENT AND THE RECEIVER
- CONNECT THE EQUIPMENT INTO AN OUTLET ON A CIRCUIT DIFFERENT FROM
THAT OF THE RECEIVER
- CONSULT THE DEALER OR AN EXPERIENCED AUDIO/TELEVISION TECHNICIAN
NOTE:
Connecting this device to peripheral devices that do not comply with Class B requirements, or
using an unshielded peripheral data cable, could also result in harmful interference to radio or
television reception.
The user is cautioned that any changes or modications not expressly approved by the party
responsible for compliance could void the user’s authority to operate this equipment.
To ensure that the use of this product does not contribute to interference, it is necessary to use

Hardware Installation
This section will guide you through the installation of the motherboard. The topics covered in this
section are:
q Installing Memory Modules
q Installing the Motherboard
q Connecting Cables and Setting Switches
Safety Instructions
To reduce the risk of re, electric shock, and injury, always follow basic safety precautions.
Remember to remove power from your computer by disconnecting the AC main source before
removing or installing any equipment from/to the computer chassis.
10
Hardware Installation
Installing Memory Modules
Your new motherboard has two 1.5V 204-pin slots for SO-DIMM DDR3 memory. These slots
support 1 GB/2 GB DDR3 devices. There must be at least one memory bank populated to ensure
normal operation. Refer to the following recommendations to install memory modules.
1.5V
1.5V
Note that a memory module has a notch, so it can only t in one direction. Refer to the following
procedure to install memory modules into the slots on the motherboard.
1. Unlock a SO-DIMM slot by pressing the module clips outward.
2. Align the memory module to the SO-DIMM slot, and insert the module vertically into the
slot. The plastic clips at both sides of the slot automatically lock the SO-DIMM into the
connector.
DDRIII-1
DDRIII-2
Note: When installing only one SO-DIMM DDR3 module, please insert it into the DDRIII-2
slot.

Intel D2550-ITX series Motherboard
Installing the Motherboard
The sequence of installing the motherboard into the chassis depends on the chassis you are
using and if you are replacing an existing motherboard or working with an empty chassis. Deter-
mine if it would be easier to make all the connections prior to this step or to secure the mother-
board and then make all the connections. It is normally easier to secure the motherboard rst.
Use the following procedure to install the I/O shield and secure the motherboard into the chassis.
Note: Be sure that the CPU fan assembly has enough clearance for the chassis covers
to lock into place and for the expansion cards. Also make sure the CPU Fan assembly is
aligned with the vents on the covers.
Installing the I/O Shield
The motherboard kit comes with an I/O shield that is used to block radio frequency transmis-
sions, protects internal components from dust and foreign objects, and promotes correct airow
within the chassis.
Before installing the motherboard, install the I/O shield from the inside of the chassis. Press the
I/O shield into place and make sure it ts securely. If the I/O shield does not t into the chassis,
you would need to obtain the proper size from the chassis supplier.
Securing the Motherboard into the Chassis
Most computer chassis have a base with mounting studs or spacers to allow the motherboard
to be secured to the chassis and help to prevent short circuits. If there are studs that do not
align with a mounting hole on the motherboard, it is recommended that you remove that stud
to prevent the possibility of a short circuit. In most cases, it is recommended to secure the
motherboard with spacers.
1. Carefully place the motherboard onto the studs/spacers located inside the chassis.
2. Align the mounting holes with the studs/spacers.
3. Align the connectors to the I/O shield.
4. Ensure that the fan assembly is aligned with the chassis vents according to the fan assembly
instruction.
5. Secure the motherboard with screws.
12
Hardware Installation
Installing an mSATA SSD module (optional)
The motherboard supports one mSATA SSD via mini PCIe slot. Users please install the mSATA
SSD module according to the following instructions.
1. Locate the Mini-PCIe slot of the motherboard, and insert an mSATA SSD into the slot at a 45
degree angle.
2. Gently press down on the mSATA SSD with one nger and secure the screws.
Note:
1. The motherboard shipped in the box does not contain an mSATA SSD.
2. You can only use either mSATA or SATA2 device at a time. The default working mode is
SATA2. The SATA2 will become unavailable when mSATA SSD is installed.
3. When the SATA2 device works, the LED indicator D2 red light is on; when the mSATA
device works, the LED indicator D2 green light is on.
