The IMBA-8654 Super I/O Enhanced Hardware Monitor also monitors the following fan
speeds:
CPU Fan speed
System Fan speed
The values for the above environmental parameters are all recorded in the BIOS
Hardware Health Configuration menu.
2.9.2 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the IMBA-8654 are listed below.
Minimum Operating Temperature: 0ºC (32°F)
Maximum Operating Temperature: 60°C (140°F)
A cooling fan and heat sink must be installed on the CPU. Thermal paste must be
smeared on the lower side of the heat sink before it is mounted on the CPU. Heat sinks
are also mounted on the northbridge and southbridge chipsets to ensure the operating
temperature of these chips remain low.

3.1 Anti-static Precautions
WARNING!
Failure to take ESD precautions during the installation of the
IMBA-8654 may result in permanent damage to the IMBA-8654 and
severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the IMBA-8654. Dry climates are especially susceptible to ESD. It is critical that
the following anti-static precautions are strictly adhered to whenever handling the
IMBA-8654 or any other electrical component.
IMBA-8654 Motherboard
Wear an anti-static wristband - Wearing a simple anti-static wristband can
help to prevent ESD from damaging the IMBA-8654.
Self-grounding - Touch a grounded conducting material before handling and
periodically while handling the IMBA-8654.
Use an anti-static pad - When configuring the IMBA-8654, place it on an
antic-static pad to reduce the possibility of ESD damage.
Only handle the edges of the IMBA-8654 - When handling the IMBA-8654,
hold it by its edges.

3.2 Unpacking
3.2.1 Unpacking Precautions
When the IMBA-8654 is unpacked, please do the following:
Follow the anti-static precautions outlined in Section 3.1.
Make sure the packing box is facing upwards so the IMBA-8654 does not fall
out of the box.
Make sure all the components shown in Section 3.3 are present.
3.3 Unpacking Checklist
NOTE:
If any components listed in the checklist below are missing, do not
proceed with the installation. Contact the IEI reseller or vendor the
IMBA-8654 was purchased from or contact an IEI sales representative
directly by sending an email to sales@iei.com.tw

5.1 Anti-static Precautions
WARNING!
Failure to take ESD precautions during the installation of the
IMBA-8654 may result in permanent damage to the IMBA-8654 and
severe injury to the user.
Electrostatic discharge (ESD) can cause serious damage to electronic components,
including the IMBA-8654. Dry climates are especially susceptible to ESD. It is therefore
critical that whenever the IMBA-8654, or any other electrical component is handled, the
following anti-static precautions are strictly adhered to.
IMBA-8654 Motherboard
Wear an anti-static wristband: Wearing a simple an t i-static wristband 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.
Use an anti-static pad: When configuring the IMBA-8654, place it on an
antic-static pad. This reduces the possibility of ESD damage.
Only handle the edges of the PCB: When handling the PCB, hold it by its
edges.

5.2 Installation Considerations
NOTE:
The following installation notices and installation considerations should
be read and understood before the IMBA-8654 is installed. All
installation notices pertaining to the installation of the IMBA-8654
should be strictly adhered to. Failing to adhere to these precautions
may lead to severe damage of the IMBA-8654 and injury to the person
installing the motherboard.
5.2.1 Installation Notices
WARNING!
The installation instructions described in this manual should be
carefully followed in order to prevent damage to the IMBA-8654 and
injury to the user.
Before and during the installation please DO the following:
Read the user manual:
o The user manual provides a complete description of the IMBA-8654
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 IMBA-8654 on an antistatic pad:
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 IMBA-8654:
Page 81
Page 100
o When working with the IMBA-8654, 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 IMBA-8654 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.
