Preface
Thank you for your purchase of the C24AX industrial embedded motherboard. This design was
based on the Intel® C246 (Coffee Lake) chipset and the 8th and 9th generation Intel Core and XEON
single processor family providing the ideal platform to industrial applications that require reliability
and high performance. With proper installation and maintenance, your board will provide years of
high performance and trouble free operation.
This manual provides a detailed explanation into the installation and use of the C24AX industrial
embedded motherboard. It is written for the novice PC user/installer. However, as with any major
computer component installation, previous experience is helpful and should you not have prior
experience, it would be prudent to have someone assist you in the installation.

Safety Precautions Warning!
Static Electricity Warning!
The C24AX motherboard has been designed as rugged as possible but can still be damaged if jarred
sharply or struck. Handle the motherboard with care.
It contains delicate electronic circuits that can be damaged or weakened by static electricity. Before
removing the board from its protective packaging, it is strongly recommended that you use a
grounding wrist strap. The grounding strap will safely discharge any static electricity build up in your
body and will avoid damaging the motherboard. Do not walk across a carpet or linoleum floor with
the bare board in hand.
FCC Notice

part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio communications. Operation of
this equipment in a residential area is likely to cause harmful interference in which case the user will
be required to correct the interference.
You are cautioned that any change or modifications to the equipment not expressly approved by the
party responsible for compliance could void your authority to operate such equipment.
CE Notice
This equipment has been designed to comply with CE. In a domestic environment this product may
cause radio interference in which case the user may be required to take adequate measures.
