Safety Summary
Safety Depends On You
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 violates safety standards of design, manufacture, and intended use of the equipment. Motorola,
Inc. assumes no liability for the customer’s failure to comply with these requirements.
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.
The equipment is supplied with a three-conductor AC power cable. The power cable must either be plugged
into an approved three-contact electrical outlet or used with a three-contact to two-contact adapter, with the
grounding wire (green) firmly 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.
Do Not Operate in an Explosive Atmosphere.
Do not operate the equipment in the presence of flammable gases or fumes. Operation of any electrical
equipment in such an environment constitutes a definite safety hazard.
Keep Away From Live Circuits.
Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or
other qualified maintenance personnel may remove equipment covers for internal subassembly or
component replacement or any internal adjustment. Do not replace components with power cable
connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To
avoid injuries, always disconnect power and discharge circuits before touching them.
Do Not Service or Adjust Alone.
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and
resuscitation, is present.
Use Caution When Exposing or Handling the CRT.
Breakage of the Cathode-Ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion).
To prevent CRT implosion, avoid rough handling or jarring of the equipment. Handling of the CRT should
be done only by qualified maintenance personnel using approved safety mask and gloves.
Do Not Substitute Parts or Modify Equipment.
Because of the danger of introducing additional hazards, 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 safety features are maintained.
Dangerous Procedure Warnings.
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.

Cooling Requirements
The Motorola MVME162 Embedded Controller is specified, designed, and
tested to operate reliably with an incoming air temperature range from 0° to
55° C (32° to 131° F) with forced air cooling at a velocity typically achievable
by using a 100 CFM axial fan. Temperature qualification is performed in a
standard Motorola VMEsystem 3000 chassis. Twenty-five watt load boards
are inserted in two card slots, one on each side, adjacent to the board under
test, to simulate a high power density system configuration. An assembly of
three axial fans, rated at 100 CFM per fan, is placed directly under the VME
card cage. The incoming air temperature is measured between the fan
assembly and the card cage, where the incoming airstream first encounters the
controller under test. Test software is executed as the controller is subjected to
ambient temperature variations. Case temperatures of critical, high power
density integrated circuits are monitored to ensure component vendors
specifications are not exceeded.
While the exact amount of airflow required for cooling depends on the
ambient air temperature and the type, number, and location of boards and
other heat sources, adequate cooling can usually be achieved with 10 CFM
and 490 LFM flowing over the controller. Less airflow is required to cool the
controller in environments having lower maximum ambients. Under more
favorable thermal conditions, it may be possible to operate the controller
reliably at higher than 55° C with increased airflow. It is important to note that
there are several factors, in addition to the rated CFM of the air mover, which
determine the actual volume and speed of air flowing over the controller.
Special Considerations for Elevated Temperature Operation
The following information is for users whose applications for the MVME162
may subject it to high temperatures.
The MVME162 uses commercial grade devices. Therefore, it can operate in an
environment with ambient airtemperatures from 0°C to 70° C. Several factors
influence the ambient temperature seen by components on the MVME162.
Among them are inlet air temperature; air flow characteristics; number, types,
and locations of IndustryPack (IP) modules; power dissipation of adjacent
boards in the system, etc.
A temperature profile of the MVME162-023 was developed in an MVME945
12-slot VME chassis. This board was loaded with one GreenSpring IP-Dual
P/T module (position a) and three GreenSpring IP-488 modules (positions b,
c, and d). One twenty-five-watt load board was installed adjacent to eachside
of the board under test. The exit air velocity was approximately 200 LFM

Specifications
MVME162/D2 1-5

between the MVME162 and the IP-Dual P/T module. Under these conditions,
a 10° C rise between the inlet and exit air was observed. At 70° C exit air
temperature (60° C inlet air), the junction temperatures of devices on the
MVME162 were calculated (from the measured case temperatures) and did
not exceed 100° C.
Caution
For elevated-temperature operation, the user must perform
similar measurements and calculations to determine what
operating margin exists in a specific environment.
The following are some steps that the user can take to help make elevated-
temperature operation possible:
1. Position the MVME162 board in the chassis for maximum airflow over the
component side of the board.
2. Avoid placing boards with high power dissipation adjacent to the
MVME162.
3. Use low-power IP modules only. The preferred locations for IP modules
are position a (J2 and J3) and position d (J18 and J19).
FCC Compliance
The MVME162 was tested without IndustryPacks in an FCC-compliant chassis
and meets the requirements for Class A equipment. FCC compliance was
achieved under the following conditions:
1. Shielded cables on all external I/O ports.
2. Cable shields connected to earth ground via metal shell connectors
bonded to a conductive module front panel.
3. Conductive chassis rails connected to earth ground. This provides the
path for connecting shields to earth ground.
4. Front panel screws properly tightened.
For minimum RF emissions, it is essential that the conditions above be
implemented. Failure to do so could compromise the FCC compliance of the
equipment containing the module.

General Description
The MVME162 is a double-high VMEmodule equipped with an MC68LC040
or optional MC68040 microprocessor. (The MC68040 microprocessor has a
floating-point coprocessor; the MC68LC040 does not.)
The MVME162 has 1MB, 4MB, or 8MB of parity-protected DRAM; 512KB
SRAM (with battery backup); a TOD clock (with battery backup); an optional
LAN Ethernet transceiver interface with DMA, two serial ports (EIA-232-D
and EIA-232-D/EIA-530); six tick timers with watchdog timer(s); optional
SCSI bus interface with DMA; VMEbus interface (local bus to
VMEbus/VMEbus to localbus, with A16/A24/A32,D8/D16/D32 buswidths
and a VMEbus system controller).
Input/Output
Input/Output (I/O) signals are routed through backplane connectorP2. A P2
adapter board or LCP2 adapter board routes the signals and grounds from
connector P2 to an MVME712 series transition module (MVME712-12,
MVME712-13, MVME712A, MVME712AM, or MVME712M). The transition
module routes the signals to the appropriate configuration headers and
industry-standard connectors. Refer to the MVME712-12, MVME712-13,
MVME712A, MVME712AM, and MVME712B Transition Modules and LCP2
Adapter Board User’s Manual or the MVME712M Transition Module and P2
Adapter Board User’s Manual for more information.
Notes
When used with the MVME162, only serial ports 2 and 4 on
the MVME712 are available for use. Serial ports 1 and 3and
the printer port are not connected to any MVME162 circuits
and should not be used.
An I/O device may be connected to serial port 1 (or 2) on the
MVME162 or to serial port 2 (or4) on the MVME712, but not
both. (That is, if an I/O device is connected to MVME162
port 1, no other I/O device should be connected to
MVME712 port 2; they are functionally the same port.)
