Safety Summary
The following general safety precautions must be observed during all phases of operation, service, and repair of this
equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual could result
in personal injury or damage to the equipment.
The safety precautions listed below represent warnings of certain dangers of which Motorola is aware. You, as the
user of the product, should follow these warnings and all other safety precautions necessary for the safe operation of
the equipment in your operating environment.
Ground the Instrument.
To minimize shock hazard, the equipment chassis and enclosure must be connected to an electrical ground. If the
equipment is supplied with a three-conductor AC power cable, the power cable must be plugged into an approved
three-contact electrical outlet, with the grounding wire (green/yellow) reliably connected to an electrical ground
(safety ground) at the power outlet. The power jack and mating plug of the power cable meet International
Electrotechnical Commission (IEC) safety standards and local electrical regulatory codes.
Do Not Operate in an Explosive Atmosphere.
Do not operate the equipment in any explosive atmosphere such as in the presence of flammable gases or fumes.
Operation of any electrical equipment in such an environment could result in an explosion and cause injury or damage.
Keep Away From Live Circuits Inside the Equipment.
Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other
qualified service personnel may remove equipment covers for internal subassembly or component replacement or any
internal adjustment. Service personnel should not replace components with power cable connected. Under certain
conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, such personnel
should always disconnect power and discharge circuits before touching components.
Use Caution When Exposing or Handling a CRT.
Breakage of a Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion). To prevent
CRT implosion, do not handle the CRT and avoid rough handling or jarring of the equipment. Handling of a CRT
should be done only by qualified service personnel using approved safety mask and gloves.
Do Not Substitute Parts or Modify Equipment.
Do not install substitute parts or perform any unauthorized modification of the equipment. Contact your local
Motorola representative for service and repair to ensure that all safety features are maintained.
Observe Warnings in Manual.
Warnings, such as the example below, precede potentially dangerous procedures throughout this manual. Instructions
contained in the warnings must be followed. You should also employ all other safety precautions which you deem
necessary for the operation of the equipment in your operating environment.
Warning
To prevent serious injury or death from dangerous voltages, use extreme
caution when handling, testing, and adjusting this equipment and its
components.

About This Manual
MVME162P4 VME Embedded Controller Installation and Use provides
instructions for hardware preparation and installation; a board-level
hardware overview; and firmware-related general information and startup
instructions for the MVME162P-2xx and -3xx series of embedded

Terminology
A character precedes a data or address parameter to specify the numeric
format, as follows (if not specified, the format is hexadecimal):
An asterisk (∗) following a signal namefor signals thatarelevelsignificant
denotes that the signal is true or valid when the signal is low. An asterisk
(∗) following a signal name for signals that are edge significant denotes
that the actions initiated by that signal occur on high to low transition.
In this manual, assertion and negation are used to specify forcing a signal
to a particular state. In particular, assertion and assert refer to a signal that
is active or true; negation and negate indicate a signal that is inactive or
false.Thesetermsare usedindependentlyof thevoltagelevel(highor low)
that they represent.

Installation
Introduction
This chapter provides unpacking instructions, hardware preparation
guidelines, and installation instructions for the MVME162P4 VME
Embedded Controller. Hardware preparation of the MVME712 series

Unpack the equipment from the shipping carton. Refer to the packing list
and verify that all items are present. Save the packing material for storing
and reshipping of equipment.
!
Caution
Avoid touching areas of integrated circuitry; static discharge can damage
circuits.
ESD Precautions
This section applies to all hardware installations you may perform that
involve the MVME162P4 board.
Use ESD
Wrist Strap
Motorola strongly recommends the use of an antistatic wrist strap and a
conductive foam pad when you install or upgrade the board. Electronic
components can be extremely sensitive to ESD. After removing the board
from the chassis or from its protective wrapper, place the board flat on a
grounded, static-free surface, component side up. Do not slide the board
over any surface.
If no ESD station is available, you can avoid damage resulting from ESD
by wearing an antistatic wrist strap (available at electronics stores). Place
the strap around your wrist and attach the grounding end (usually a piece
of copper foil or an alligator clip) to an electrical ground. An electrical
ground can be a piece of metal that literally runs into the ground (such as
an unpainted metal pipe) or a metal part of a groundedelectrical appliance.
An appliance is grounded if it has a three-prong plug and is plugged into a
three-prong grounded outlet. You cannot use the chassis in which you are
installing the MVME162P4 itself as a ground, because the enclosure is
unplugged while you work on it.
!
Warning
Turn the system’s power off before you perform these procedures. Failure
to turn the power off before opening the enclosure can result in personal
injuryor damage to the equipment. Hazardousvoltage, current, and energy
levels are present in the chassis. Hazardous voltages may be present on
power switch terminals even when the power switch is off. Never operate
the system with the cover removed. Always replace the cover before
powering up the system.

Hardware Preparation and Installation

Preparing the Board
To produce the desired configuration and ensure proper operation of the
MVME162P4, you may need to reconfigure hardware to some extent
before installing the module.
Most options on the MVME162P4 are under software control: By setting
bits in control registers after installing the module in a system, you can
modify its configuration. (The MVME162P4 registers are described in
Chapter 3 under ENV – Set Environment, and/or in the MVME1x2P4 VME
EmbeddedControllerProgrammer'sReferenceGuideaslistedin “Related
Documentation” in Appendix E.)
Some options, though, are not software-programmable. Such options are
either set by configuration switches or are controlled through physical
installation or removal of header jumpers or interface modules on the base
board.
MVME162P4 Configuration
Figure 1-1 illustrates the placement of the jumper headers, connectors,
configuration switches, and various other components on the
MVME162P4. Manually configurable jumper headers and configuration
switches on the MVME162P4 are listed in the following table.
Note Jumper J3 is not listed, as it is provided for manufacturing
purposes only and cannot be configured.
