4.1 Anti-static Precautions

Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the IMB-9452. (Dry climates are especially susceptible to ESD.) It is therefore
critical that whenever the IMB-9452 (or any other electrical component) is handled, the
following anti-static precautions are strictly adhered to.

 Wear an anti-static wrist band: Wearing a simple anti-static wrist band can

help to prevent ESD from damaging the board.

 Self-grounding: Before handling the board touch any grounded conducting

material. During the time the board is handled, frequently touch any
conducting materials that are connected to the ground.

4.2 Installation Considerations

IMB-9452 Motherboard

NOTE:

The following installation notices and installation considerations should be
read and understood before the motherboard is installed. All installation
notices pertaining to the installation of the motherboard should be strictly
adhered to. Failing to adhere to these precautions may lead to severe
damage of the motherboard and injury to the person installing the
motherboard.

4.2.1 Installation Notices

Before and during the installation of the IMB-9452, please do the following:

 Read the user manual

o The user manual provides a complete description of the IMB-9452,

installation instructions and configuration options.

 Wear an electrostatic discharge cuff (ESD)

o Electronic components are easily damaged by ESD. Wearing an ESD cuff

removes ESD from the body and helps prevent ESD damage.

 Place the motherboard on an antistatic pad

Page 80

IEI® Technology, Corp.

IMB-9452 Motherboard

o When installing or configuring the motherboard, place it on an antistatic

pad. This helps to prevent potential ESD damage.

 Turn off all power to the IMB-9452

o When working with the motherboard, make sure that it is disconnected

from all power supplies and that no electricity is being fed into the system.

Before and during the installation of the IMB-9452 DO NOT:

 remove any of the stickers on the PCB board. These stickers are required for

warranty validation.

 use the product before verifying all the cables and power connectors are

properly connected.

 allow screws to come in contact with the PCB circuit, connector pins, or its

components.

4.3 Unpacking

NOTE:

If any of the items listed below are missing when the IMB-9452 is
unpacked, do not proceed with the installation and contact the IMB-9452
reseller or vendor.

4.3.1 Unpacking Precautions

Before installing the IMB-9452, unpack the motherboard. Some components on IMB-9452
are very sensitive to static electricity and can be damaged by a sudden rush of power. To

WARNING!

CPUs are expensive and sensitive components. When installing the CPU
please be careful not to damage it in anyway. Make sure the CPU is installed
properly and ensure that a heat sink and CPU cooling fan is properly installed
before the motherboard is run or else both the CPU and the board may be
damaged.

To install an Intel 479-pin CPU onto the motherboard, follow the steps below:

Step 1: Is the CPU retention screw in an unlocked position? When shipped, the

retention screw of the CPU socket should be in the unlocked position. If it is not
in the unlocked position, use a screwdriver to position it in an unlocked position.
(See

Figure 4-1)

Figure 4-1: Make sure the CPU socket retention screw is unlocked

Step 2: Inspect the CPU socket. Make sure there are no bent pins and make sure the

socket contacts are free of foreign material. If any debris is found, re move it with
compressed air.

Step 3: Correctly position the CPU. Make sure the pin 1 mark matches the cut edge

on the CPU socket. Carefully place the CPU on top of the socket. When properly
placed, the CPU should be easily inserted into the socket.

Step 4: Insert the CPU. To insert the CPU into the socket, hold the CPU by its edges

and follow the instructions below:

Step 5: Correctly orientate the CPU with the IHS (Integrated Heat Sink) side facing

upward.
