2. Getting Started
Before You Begin
Before handling your ETXexpress-WPM, read the instructions and safety guidelines on
the following pages to prevent damage to the product and to ensure your own personal
safety.
Always use caution when handling or operating a computer. Only qualified,
experienced, authorized electronics service personnel should access the interior
of a computer. The power supplies produce high voltages and energy hazards,
which can cause bodily harm.
If you have any problems or questions about the unit, please contact Kontron
Post-Sales Technical Support.
WARNING
High voltages are present inside a computer chassis when the
unit’s power cord is plugged into an electrical outlet. Turn off
system power, turn off the power supply, and then disconnect
the power cord from its source before removing the chassis
cover. Turning off the system power switch does not remove
power to components.
Unpacking
When unpacking, follow these steps:
1) After opening the box, save it and the packing material for possible future
shipment.
2) Remove all items from the box. If any items listed on the purchase order are
missing, notify Kontron customer service immediately.
3) Inspect the product for damage. If there is damage, notify Kontron customer
service immediately. Refer to “Guarantee and Warranty Policy” for the return
procedure.

page 14 ETXexpress-WPM User’s Guide
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1) Turn off the computer and any peripherals.
2) Disconnect the computer and peripherals from their power sources or
subsystems to prevent electric shock or system board damage. This does not
apply when hot swapping parts.
3) Follow the guidelines provided in “Preventing Electrostatic Discharge” in the
following section.
4) Disconnect any telephone or telecommunications lines from the computer.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to system boards, wait five seconds after turning
off the computer before removing a component, removing a system board, or
disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. Some cables have a connector with locking tabs. If you are
disconnecting this type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before connecting a cable, make sure
both connectors are correctly oriented and aligned
Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation and
follow proper ESD procedure to reduce the risk of damage to components. Kontron
strongly encourages you to follow proper ESD procedure, which can include wrist straps
and smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
When unpacking a static-sensitive component from its shipping carton, do not
remove the component’s antistatic packing material until you are ready to install
the component in a computer. Just before unwrapping the antistatic packaging,
be sure you are at an ESD workstation or grounded. This will discharge any
static electricity that may have built up in your body.
When transporting a sensitive component, first place it in an antistatic container
or packaging.
Handle all sensitive components at an ESD workstation. If possible, use antistatic
floor pads and workbench pads.

ETXexpress-WPM User’s Guide page 15
Handle components and boards with care. Don’t touch the components or
contacts on a board. Hold a board by its edges or by its metal mounting bracket.
Do not handle or store system boards near strong electrostatic, electromagnetic,
magnetic, or radioactive fields.

page 16 ETXexpress-WPM User’s Guide

ETXexpress-WPM User’s Guide page 17
3. Introduction
ETXexpress-WPM
The ETXexpress-WPM (Type 3 COM Express Module) is based on the Intel® Pentium®
M processor (up to 2 GHz) and the Intel Express chipset Intel 3100 (Whitmore Lake)
that supports up to 12 PCI Express lanes for high I/O bandwidth. The ETXexpress-
WPM (ETXexpress-WPM) is ideal for network equipment and telecom OEMs as well as
test and measurement OEMs. The ETXexpress-WPM Module does not support video
output to CRT or flat panels, nor does it support sound.
This latest addition to Kontron’s line of COM Express compliant Computer-On-Modules
(COMs) supports up to 512MB, 1GB, and 2GB (future) system memory in each of the
two on-board sockets for 244-pin mini-DIMM modules in vertical configuration or 1 on-
board socket in horizontal configuration.
In line with the fact that PCI Express is the primary data path for the vast majority of
future-focused embedded applications, the ETXexpress-WPM has up to 12 PCI
Express lanes. For fast communications, two of the PCI Express lanes that the chipset
supports facilitate the module’s dual Gigabit Ethernet (GbE) capability. A 10/100Base-
Tx Ethernet port also is available, for a total of three Ethernet connections.
Non PCI Express components such as PCI plug-in cards can still be supported with the
PCI 2.1, 32 bit interface that is included in the ETXexpress-WPM Module.
The ETXexpress-WPM provides fast interfaces for external peripherals by way of
support for four USB 2.0 ports and four SerialATA ports (Type I).
Five mounting holes on the board provide secure mounting to better tolerate shock and
vibration.

page 18 ETXexpress-WPM User’s Guide
ETXexpress Module Overview
All Kontron ETXexpress Modules are based upon the COM Express™ Specification,
which Kontron played the lead role in developing.
The international COM Express™ Specification defines five Module Types (1-5) and two
new form factor sizes:
Basic (95mm x 125mm) Module
Extended (110mm x 155mm) Module
The primary difference between the Basic and Extended Modules is that Extended
Modules have a larger board size and a thermal envelope.
Five Module Pin-out Types (1-5) exist for Basic and Extended modules, each offering
different functionalities. The ETXexpress-WPM is a Type 3 Basic Module. For a
complete explanation of the features, pin-outs and signals of each of the Module Pin-out
Types 1-5, please see the COM Express™ Specification. The COM Express™
Specification is available on the PICMG (PCI Industrial Computer Manufacturers Group)
Web site: www.picmg.org. There is a fee for the document.
Understanding ETXexpress Functionality
The ETXexpress-WPM Type 3 Module contains two mounting connectors, each of
which has two rows. The primary connector holds Row A and Row B. The secondary
connector holds Row C and D.
The primary connector (Rows A and B) features the following functionality:
Ethernet
SATA
USB 2.0
LPC, an Intel proprietary low-pin count (LPC), which supports low-speed devices
such as RS-232 serial and parallel ports.
The secondary connector (Rows C and D) provides support for the following buses and
I/O:
PCI Express
PCI
Additional Ethernet Ports

ETXexpress-WPM User’s Guide page 19
ETXexpress Reference Documents
This User Guide serves as one of three principal references for an ETXexpress COM
design. The other two references include:
The COM Express™ Specification, which defines the two COM Express™ form
factors (Basic and Extended), the five module types, pin-outs, and signals. You
should read this document first. You can find the COM Express™ Specification
on the PICMG (PCI Industrial Computer Manufacturers Group) Web site:
www.picmg.org. There is a fee for the document. All Kontron ETXexpress
Modules are based upon the COM Express™ Specification. Kontron played a
leading role in developing the COM Express™ Specification.
The ETXexpress Design Guide serves as a general guide for carrier board design,
with a focus on maximum flexibility to accommodate a range of ETXexpress
modules.
About PCI Express
PCI Express has become the primary data path for upcoming x86 based systems. Non
PCI Express components such as PCI plug-in cards can still be supported with the PCI
2.1 32-bit interface. ETXexpress COMs will continue supporting the PCI bus for legacy
applications.
PCI Express is an international I/O interconnect bus standard that expands on and
doubles the data transfer rates of the original PCI bus standard. PCI Express is a two-
way, serial connection that carries data in packets along two pairs of point-to-point data
lanes, compared to the single parallel data bus of traditional PCI that routes data at a
set rate.
Initial bit rates for PCI Express reach 2.5Gb/s per lane direction, which equate to data
transfer rates of approximately 200MB/s. A group of companies, headed by Kontron,
developed the COM Express™ Specification so that high-speed interconnects such as
USB 2.0 and Gigabit Ethernet would have an I/O architecture suitable for their high
transfer speeds.
