For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
As a precaution and in case of danger, the power connector must be easily accessible. The power connector is the
product’s main disconnect device.
Warning
All operations on this product must be carried out by sufficiently skilled personnel only.
Electric Shock!
Before installing a non hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This also applies to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair, and maintenance operations
on this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing any work on this product.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected. The earth ground cable shall be the last cable to be disconnected or the first
cable to be connected when performing installation or removal procedures on this product.
Special Handling and Unpacking Instruction
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care
must be taken during all handling operations and inspections of this product, in order to
ensure product integrity at all times.
Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it is
otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is not
guaranteed, it is important for the user to be electrically discharged before touching the product with his/her hands
or tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,
jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the product is not placed
on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage the
batteries or conductive circuits on the product.

1/ Introduction
1.1. Product Description
COM-HPC Client Evaluation Carrier (ADHC) is an evaluation, testing and validation carrier board (baseboard) for COM-
HPC® modules in ATX form factor. The ADHC will allow more flexibility with respect to the 10 GbE configurations. Main
purpose of this carrier board is to bring out all the signals from COM-HPC® connector of COMh modules to industry
standard interfaces. The key features are:
Support of 64 PCIe lanes via various PCIe and M.2 slots
8x SFP28 cages
1x 10/1GBase-T interface
4x USB 3.2 Gen2.1
2x SATA
BIOS POST-Code display

1.2. Product Naming Clarification
COM-HPC® defines a Computer-on-Module, or COM, with all the components necessary for a bootable host computer,
packaged as a super component. The product name for Kontron COM-HPC® Computer-On-Modules consists of:
Industry standard short form
COMh-
Two different pin-out types:
c = client
s = server
Module form factor
a = 95 mm x 120 mm
b = 120 mm x 120 mm
c = 160 mm x 120 mm
d = 160 mm x 160 mm
e = 200 mm x 160 mm
The COM-HPC Client Evaluation Carrier (ADHC) fits all types of modules.
1.3. Understanding COM-HPC® Functionality
All Kontron COM-HPC® extended, basic and compact modules contain two 2x 100pin connectors; each of it has two
rows called Row A & B on primary connector and Row C & D on secondary connector. The COM-HPC® Computer-On-
Module (COM) features the following maximum amount of interfaces according to the PCI Industrial Computer
Manufacturers Group (PICMG) module Pin-out type.

1.4. COM-HPC® Documentation
The COM-HPC® Specification defines the COM-HPC® module form factor, pin-out, and signals. This document is
available at the PICMG® website by filling out the order form.
1.5. COM-HPC® Benefits
COM-HPC® modules are compact and highly integrated computers. All modules feature a standardized form factor
and connector layout which carry a specified set of signals. Each COM is based on the COM-HPC® specification. This
standardization allows designers to create a single-system baseboard that can accept present and future COM-HPC®
modules.
The baseboard designer can optimize exactly how each of these functions implements physically. Designers can
place connectors precisely where needed for the application on a baseboard designed to optimally fit a system’s
packaging.
A single baseboard design can use a range of COM-HPC® modules with different sizes and pin-outs. This flexibility
can differentiate products at various price/performance points. The modularity of a COM-HPC® solution also ensures
against obsolescence when computer technology evolves. A properly designed COM-HPC® baseboard can work with
several successive generations of COM-HPC® modules.
A COM-HPC® baseboard design has many advantages of a customized computer-board design and, additionally,
delivers better obsolescence protection, heavily reduced engineering effort, and faster time to market.
