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 merchandise
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.
Initial Inspection
Before you begin installing your motherboard, please make sure that the following
materials have been shipped:
AIMB-503 Intel LGA1150 Core i7/i5/i3 Micro ATX Motherboard
SATA HDD cable x 2
I/O port bracket x 1
Startup manual x 1
Driver CD x 1
Warranty card x 1
COM port cable kit x 3
If any of these items are missing or damaged, contact your distributor or sales repre-
sentative immediately. We have carefully inspected the AIMB-503 mechanically and
electrically before shipment. It should be free of marks and scratches and in perfect
working order upon receipt. As you unpack the AIMB-503, check it for signs of ship-
ping damage. (For example, damaged box, scratches, dents, etc.) If it is damaged or
it fails to meet the specifications, notify our service department or your local sales
representative immediately. Also notify the carrier. Retain the shipping carton and
packing material for inspection by the carrier. After inspection, we will make arrange-
ments to repair or replace the unit.

1.4 Jumpers and Connectors
Connectors on the AIMB-503 motherboard link it to devices such as hard disk drives
and a keyboard. In addition, the board has a number of jumpers used to configure
your system for your application.
The tables below list the function of each of the board jumpers and connectors. Later
sections in this chapter give instructions on setting jumpers. Chapter 2 gives instruc-
tions for connecting external devices to your motherboard.

1.7 Safety Precautions
Warning! Always completely disconnect the power cord from chassis whenever
you work with the hardware. Do not make connections while the power
is on. Sensitive electronic components can be damaged by sudden
power surges. Only experienced electronics personnel should open the
PC chassis.
Caution! Always ground yourself to remove any static charge before touching the
motherboard. Modern electronic devices are very sensitive to electro-
static discharges. As a safety precaution, use a grounding wrist strap at
all times. Place all electronic components on a static-dissipative surface
or in a static-shielded bag when they are not in the chassis.
Caution! The computer is provided with a battery-powered real-time clock circuit.
There is a danger of explosion if battery is incorrectly replaced. Replace
only with same or equivalent type recommended by the manufacturer.
Discard used batteries according to manufacturer's instructions.
Caution! There is a danger of a new battery exploding if it is incorrectly installed.
Do not attempt to recharge, force open, or heat the battery. Replace the
battery only with the same or equivalent type recommended by the man-
ufacturer. Discard used batteries according to the manufacturer’s
instructions.

1.8 Jumper Settings
This section provides instructions on how to configure your motherboard by setting
the jumpers. It also includes the motherboards's default settings and your options for
each jumper.
1.8.1 How to Set Jumpers
You can configure your motherboard to match the needs of your application by set-
ting the jumpers. A jumper is a metal bridge that closes an electrical 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” (or turn ON) a jumper, you connect the pins
with the clip. To “open” (or turn OFF) a jumper, you remove the clip. Sometimes a
jumper consists of a set of three pins, labeled 1, 2, and 3. In this case you connect
either pins 1 and 2, or 2 and 3. A pair of needle-nose pliers may be useful when set-
ting jumpers.
1.8.2 CMOS Clear (CMOS1)
The AIMB-503 motherboard contains a jumper that can erase CMOS data and reset
the system BIOS information. Normally this jumper should be set with pins 1-2
closed. If you want to reset the CMOS data, set CMOS1 to 2-3 closed for just a few
seconds, and then move the jumper back to 1-2 closed. This procedure will reset the
CMOS to its default setting.
