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 modications 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
shielded I/O cables.

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.
Hardware Installation

10
Intel H55-ITX series Motherboard
Preparing the Motherboard
The motherboard shipped in the box does not contain a CPU or memory DIMM. You need to
purchase them to complete this installation.
Installing the CPU
Be very careful when handling the CPU. Make sure not to bend or break any pins on the back.
Hold the processor only by the edges and do not touch the bottom of the processor.
The following illustration shows CPU installtaion components
1. Unhook the socket lever by pushing down
and away from the socket.
2. Lift the socket lever and the load plate to
fully open position.
3. Use your thumb and forenger to lift the cap
up vertically.
● Be careful not to touch the socket contacts.
4. Hold the processor with your thumb and
forenger. Insert the processor into the socket
vertically.
● Align the CPU pin 1 mark with the pin 1
corner of the CPU socket.
5. Make sure the CPU is fully seated, and then
replace the load plate.
● Be sure that the front end of the load
plate is under the shoulder screw.
6. Secure the load lever to its locked location.

11
Installing the CPU Fan
There are many different fan types that can be used with this motherboard. Follow the instruction
that came with your fan assembly. Be sure that the fan orientation is correct for your chassis type
and your fan assembly.
Installing Memory DIMMs
Your new motherboard has two 1.5V 240-pin slots for DDR3 memory. These slots support 1
GB/2 GB/4 GB DDR3 technologies. They also support dual channel DDR3 memory technology
up to 10.7 GB/s. There must be at least one memory bank populated to ensure normal operation.
Refer to the following recommendations to install memory DIMMs.
q One DIMM: Install it into slot 1 or 2. You can install the DIMM into any slot, however, slot 1
is preferred.
q Two DIMMs: Install them into slot 1 and slot 2.
Refer to the following procedure to install memory DIMMs into the slots on the motherboard.
Note that there is only one gap near the center of the DIMM slot. This slot matches the slot on
the memory DIMM to ensure the component is installed properly.
1. Unlock a DIMM slot by pressing the module clips outward.
2. Align the memory module to the DIMM slot, and insert the module vertically into the DIMM
slot. The plastic clips at both sides of the DIMM slot automatically lock the DIMM into the
connector.

Intel H55-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 assem
-bly 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 airow
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.
