Product warranty
Advantech warrants to you, the original purchaser, that each of its products
will be free from defects in materials and workmanship for one year from the
date of purchase.
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 conse-
quence 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 defective, 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 on-screen 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 mer-
chandize 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.

1.1 General Information
The MIC-3451/MIC-3451H is a 6U-sized general-purpose backplane
that provides eight 32-bit or 64-bit (optional) CompactPCI slots. It
accepts a 2-slot (8TE) or 3-slot (12TE) wide processor module and
seven peripheral modules.
The MIC-3451/MIC-3451H includes standard IDE and floppy
interface connectors on the backplane. Users can easily connect IDE
devices and floppy drives to the backplane through the P3 connector
on the system slot.
In order to provide users with a flexible system configuration, the
MIC-3451/MIC-3451H includes two standard ATX power connectors
and an optional two IEC 603-2 (DIN 41612) connectors to accept two
ATX power supplies or two 3U size plug-in power modules.
The MIC-3451/MIC-3451H provides a 6-pin connector for connect-
ing to up to 4 cooling fans. A 20-pin connector can be used for
connecting an external alarm module (MIC-3920/MIC-3921) to
detect system internal conditions, such as bus voltages and fan speed.
The MIC-3451H complies with PICMG 2.1 Hot-Swap Specification
providing full hot-swapping capability. Users can build a hot-swap
system using hot-swap plug-in boards and software.
1.2 Features
- Eight 32-bit CompactPCI slots (64-bit upon request)
- Supports hot-swappable modules (MIC-3451H)
- Accepts twoATX power supplies or two plug-in power modules
(optional, upon request)
- IDE and floppy drive interface
- Alarm board interface
- Fan interface

2.2 Slot Assignments
The CompactPCI specification defines slot numbering seperating for
physical and logical slots. Each slot has a physical number and a
logical number (refer to the CompactPCI specification version 2.0
R2.1 for further information on slot assignments). The physical
numbers are printed on the backplane, enclosed in circles or triangles,
below each slot. Slot 8, marked by a triangle, is the system slot and
can only be used by a processor module. The other slots (slot 1~7) are
peripheral slots and can be used by peripheral modules.
The logical number of each slot is defined according to the IDSEL
signal and the associated address used to select the slot. Table 2-2
shows the system slot to peripheral slot relationships on the
MIC-3451/MIC-3451H. Physical slot 8 (system slot) has a logical
number 1, physical slot 7 has a logical number 2, physical slot 6 has a
logical number 3, ..., and physical slot 1 has a logical number 8. The
connectors in logical slot 1 are designated as 1-P1, 1-P2, and 1-P3.
Nomenclature for connectors in other slots is similar, such as 2-P1,
2-P2, 3-P1, 3-P2, etc.
Connector 1-P1 is a keyed connector providing 32-bit CompactPCI
busing between the system slot and the peripheral slots (2-P1~8-P1).
Connector 1-P2 is an un-keyed connector providing 64-bit Compact-
PCI busing between the system slot and the peripheral slots (2-P2~
8-P2). Connector 1-P3 is an un-keyed 19-row connector providing
IDE device and floppy drive interfaces (Advantech’s Definition).

2.3 IDE Interface (CN1 and CN3)
The CN1 and CN3 connectors are routed to the 1-P3 connector for
connection of IDE devices such as hard disk drives and CD-ROM
drives. When using Advantech’s 6U-sized processor module, users
can connect IDE devices to the backplane, instead of direct cabling to
the processor board. This shortens the MTTR (Mean Time To Repair)
for replacing the processor board. The CN1 connector is for the
primary IDE channel and the CN3 connector is for the secondary
channel. Each channel can connect up to two IDE devices.

2.4 Floppy Disk Interface (CN4)
The CN4 connector is routed to the 1-P3 connector for connecting
floppy disk drives. With Advantech’s 6U-sized processor module,
users can connect floppy disk drives to the backplane, instead of
direct cabling to the processor board. This shortens the MTTR for
replacing the processor board. Up to two floppy disk drives can be
connected to CN4.
2.5 Alarm Board Interface (CN2)
The 20-pin connector CN2 is an interface for an external monitoring
and alarm module, such as MIC-3920/MIC-3921, which monitors the
system conditions. It contains bus voltages 3.3V, 5V, 12V and -12V,
and utilizes four fan tachometer signals and an on-off control signal.
