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. Loosen the three captive screws securing the CPU cover in sequential order (1 g 2 g 3).

2. Flip open the CPU cover.

3. Remove the CPU carrier from the CPU frame using the handle on the CPU carrier.

4. Using the handle on the CPU carrier insert the new CPU carrier with CPU installed into the CPU

frame.

NOTE: Ensure the CPU is installed in the CPU carrier in the correct orientation,

with the triangle on the CPU aligned to the top left corner of the CPU carrier.

5. Flip the CPU frame with CPU installed into place in the CPU socket.

6. Flip the CPU cover into place over the CPU socket.

7. Tighten the CPU cover screws in sequential order (1 g 2 g 3) to secure the CPU cover in place.

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.

1-5 Installing the M.2 SSD Module

WARNING:

Installation of the thermal pad over the M.2 device is required when installing an M.2 device. Lack

of the thermal pad may result in the system overheating and throttle the system performance.

CAUTION

The position of the stand-off screw will depend on the size of the M.2 device. The stand-off screw

is pre-installed for 22110 cards as standard. Refer to the size of the M.2 device and change the

position of the stand-off screw accordingly.

Follow these instructions to install the M.2 device and heat sink:

1. Insert the M.2 device into the M.2 connector.

2. Press down on the M.2 device.

3. Install the thermal pad of the M.2 device to the M.2 device.

4. Press down on the thermal pad.

5. Secure the M.2 device and its thermal pad to the motherboard with a single screw.

6. Reverse steps 1-5 to remove the M.2 device.

(2x12 Main Power Connector and 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.

Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect

it in the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU

fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat

dissipation, it is recommended that a system fan be installed inside the chassis.
