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 speciÞc 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 be plugged into an approved three-contact electrical 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 ßammable gases or fumes. Operation of any electrical equipment in such an environment constitutes a deÞnite safety hazard.

Keep Away From Live Circuits.

Operating personnel must not remove equipment covers. Only Factory Authorized Service Personnel or other qualiÞed 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 Þrst 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 qualiÞed 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 modiÞcation 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.

Dangerous voltages, capable of causing death, are present in

Speciﬁcations

General specifications for the MVME177 are listed in Table 1-3.

The following sections detail cooling requirements and FCC compliance.

Cooling Requirements

The Motorola MVME177 VMEmodule is specified, designed, and tested to operate reliably with an incoming air temperature range from 0û to 55û C (32û to 131û 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 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 module under test. Test software is executed as the module 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.

Specifications

While the exact amount of airflow required for cooling depends on:

Ambient air temperature

❏

Type of board

❏

Number of boards

❏

Location of boards

❏

Other heat sources

❏

adequate cooling can usually be achieved with 10 CFM and 490 LFM flowing over the module. Less airflow is required to cool the module in environments having lower maximum ambients. Under

1-3

General Information

more favorable thermal conditions, it may be possible to operate the module reliably at higher than 55û 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 a module.

Forced air cooling is required for the Atlas motherboard. Additional cooling is required with the installation of the MPC604 RISC processor. A 3-pin header (J17) is provided on the motherboard for powering a dedicated fan. Refer to the

Requirements

section in the

FCC Compliance

The MVME177 was tested 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 Information

Manual T erminology

Throughout this manual, a convention is used which precedes data and address parameters by a character identifying the numeric format as follows:

$ dollar speciÞes a hexadecimal character % percent speciÞes a binary number & ampersand speciÞes a decimal number

Unless otherwise specified, all address references are in hexadecimal.

An asterisk (*) following the signal name for signals which are level significant denotes that the signal is true or valid when the signal is low.

An asterisk (*) following the signal name for signals which are edge significant denotes that the actions initiated by that signal occur on high to low transition.

1-12

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. These terms are used independently of the voltage level (high or low) that they represent.

Data and address sizes are defined as follows:

❏ A byte is eight bits, numbered 0 through 7, with bit 0 being

the least significant

❏ A word is 16 bits, numbered 0 through 15, with bit 0 being the

least significant

❏ A longword is 32 bits, numbered 0 through 31, with bit 0

being the least significant

Hardware Preparation and Installation

Hardware Preparation

To select the desired configuration and ensure proper operation of the MVME177, certain option modifications may be necessary before installation. The MVME177 provides software control for most of these options. Some options cannot be done in software, so are done by jumpers on headers. Most other modifications are done by setting bits in control registers after the MVME177 has been installed in a system. (The MVME177 registers are described in

Chapter 4, and/or in the Single Board Computers Programmer's Reference Guide as listed in Related Documentation in Chapter 1).

The location of switches, jumper headers, connectors, and LED indicators on the MVME177 is illustrated in Figure 2-1.

The MVME177 has been factory tested and is shipped with the factory jumper settings described in the following sections. The MVME177 operates with its required and factory-installed Debug Monitor, MVME177Bug (177Bug), with these factory jumper settings.

Settings can be made for:

❏ General purpose readable jumpers on header (J1)

2-4

❏ SRAM backup power source select header (J2) (optional)

❏ System controller header (J6)

❏ Thermal sensing pins (J7)

❏ EPROM/Flash configuration jumper (J8)

❏ Serial port 4 clock configuration select headers (J9 and J10)

Refer to Table 2-2 to configure the jumper settings for each header.
