Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years from the date of pur-
chase. This warranty does not apply to any products which have been repaired or
altered by persons other than repair personnel authorized by Advantech, or which
have been subject to misuse, abuse, accident or improper installation. Advantech
assumes no liability under the terms of this warranty as a consequence of such
events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out-
of-warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid
to your dealer.

vii MIC-7420 User Manual
The fuses must be replaced by service person. Service person shall fully disconnect
the power before servicing to avoid the risk of electric shock.
Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive elec-
tronic components.
Always disconnect the power cord from the chassis when making adjustments. Do
not connect when the power is on. A sudden rush of power can damage sensitive
electronic components. Only experienced electronics personnel should open the
chassis. Always ground yourself to remove any static electric charge before touching
the motherboard, backplane, or add-on cards. Modern electronic devices are very
sensitive to static electric charges. Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative surface or in a static- shielded bag.

2.3 Jumpers and Connectors
2.3.1 Jumper Description
You may configure the MIC-7420 to match the needs of your application by setting
jumpers. A jumper is a metal bridge used to close an electric circuit. It consists of two
metal pins and a small metal clip (often protected by a plastic cover) that slides over
the pins to connect them. To close a jumper, you remove the clip. Sometime a jumper
will have three pins, labelled 1, 2 and 3. In this case you would connect either pins 1
and 2, or 2 and 3.
The jumpers setting are schematically depicted in this manual as follows.

MIC-7420 User Manual 8
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
2.3.2 Jumper and Connector Location
The board has a number of connectors and jumpers that allow you to configure your
system to suit your application. The table below lists the function of each of the con-
nectors and jumpers. The locations of jumpers and connector on the board are
shown in Figure 2.3.
