Hardware Installation
1-1 Installation Precautions
The motherboard contains numerous delicate electronic circuits and components which can
become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read
the user's manual and follow these procedures:
• Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or
warranty sticker provided by your dealer. These stickers are required for warranty validation.
• Always remove the AC power by unplugging the power cord from the power outlet before
installing or removing the motherboard or other hardware components.
• When connecting hardware components to the internal connectors on the motherboard,
make sure they are connected tightly and securely.
• When handling the motherboard, avoid touching any metal leads or connectors.
• It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic
components such as a motherboard, CPU or memory. If you do not have an ESD wrist
strap,keepyourhandsdryandrsttouchametalobjecttoeliminatestaticelectricity.
• Prior to installing the motherboard, please have it on top of an antistatic pad or within an
electrostatic shielding container.
• Before unplugging the power supply cable from the motherboard, make sure the power
supply has been turned off.
• Before turning on the power, make sure the power supply voltage has been set according to
the local voltage standard.
• Before using the product, please verify that all cables and power connectors of your
hardware components are connected.
• To prevent damage to the motherboard, do not allow screws to come in contact with the
motherboard circuit or its components.
• Make sure there are no leftover screws or metal components placed on the motherboard or
within the computer casing.
• Do not place the computer system on an uneven surface .
• Do not place the computer system in a high-temperature environment.
• Turning on the computer power during the installation process can lead to damage to
system components as well as physical harm to the user.
• If you are uncertain about any installation steps or have a problem related to the use of the
product,pleaseconsultacertiedcomputertechnician.
• To avoid any potential short circuit of the DIMM slots, please remove any stand-offs from the
chassis that will be located underneath the DIMM slots, before installing the motherboard
into the chassis.

Hardware Installation
1-3 Installing and Removing the CPU
Read the following guidelines before you begin to install the CPU:
• Make sure that the motherboard supports the CPU.
• Always turn off the computer and unplug the power cord from the power outlet before installing
the CPU to prevent hardware damage.
• Unplug all cables from the power outlets.
• Disconnect all telecommunication cables from their ports.
• Placethesystemunitonaatandstablesurface.
• Open the system according to the instructions.
WARNING!
Failure to properly turn off the server before you start installing components may cause serious
damage. Do not attempt the procedures described in the following sections unless you are a
qualiedservicetechnician.
Follow these instructions to Install the CPU:
1. Align and install the processor on the carrier.
NOTE: Apply thermal compound evenly on the top of the CPU. Remove the protective cover from
the underside of the heat sink.
2. Carefullyiptheheatsinkcover.Theninstallthecarrierassemblyonthebottomoftheheatsink
and make sure the gold arrow is located in the correct direction.
3. Remove the CPU cover.
NOTE: Save the CPU cover in the event that you need to remove the CPU from the socket.
4. Align the heat sink with the CPU socket by the guide pins and make sure the gold arrow is located
in the correct direction. Then place the heat sink onto the top of the CPU socket.
5. Position the rotating wires into the latch position. Tighten the screws in a sequential order
(1g2g3g4).
NOTE: When dissembling the heat sink, loosen the screws in reverse order (4g3g2g1) and
then move the rotating wires into the unlatch position.

1-4 Installing and Removing Memory
Read the following guidelines before you begin to install the memory:
•Make sure that the motherboard supports the memory. It is recommended to use memory of the
same capacity, brand, speed, and chips.
•Always turn off the computer and unplug the power cord from the power outlet before installing
the memory to prevent hardware damage.
•Memory modules have a foolproof design. A memory module can be installed in only one
direction. If you are unable to insert the memory, switch the direction.

Hardware Installation
1/2/3) ATX1/P12V_PCIE/P12V_AUX1/P12V_AUX2
(2x12 Main Power Connector and 2x3/2x4 12V Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the components
onthemotherboard.Beforeconnectingthepowerconnector,rstmakesurethepowersupplyisturnedoff
and all devices are properly installed. The power connector possesses a foolproof design. Connect the power
supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies
power to the CPU. If the 12V power connector is not connected, the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high
power consumption be used (500W or greater). If a power supply is used that does not provide the
required power, the result can lead to an unstable or unbootable system.
