Cooling Requirements

Motorola VMEmodules are specified, designed, and tested to operate reliably with an incoming air temperature range from 0 degrees C to 55 degrees C (32 degrees F to 131 degrees F) with forced air cooling. Temperature qualification is performed in a standard Motorola VMEsystem 1000 chassis. Twenty-five watt load boards are inserted in the 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 71 CFM per fan, is placed directly under the MVME 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.

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 5 CFM flowing over the module. Less air flow is required to cool the module in environments having lower maximum ambients. Under more favorable thermal conditions it may be possible to operate the module reliably at higher than 55 degrees C with increased air flow. 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 of air flowing over a module.

FCC Compliance

These MVME712 family VMEmodules were tested in an FCC-compliant chassis, and meet 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 modules.

General Information

 

General Description

The MVME712 family modules are I/O transition modules for the MVME1xx VMEmodule families. The LCP2 adapter assembly routes the I/O signals and grounds from the P2 connector on the backplane at the MVME1xx VMEmodule to the MVME712 family module. The MVME712 family module routes the signals to the appropriate industry-standard connectors on its front panel. The MVME712-13 and MVME712AM both have a built-in modem.

The MVME712x has four DB-9 connectors for the serial ports, one 25-pin connector for the printer port, and a Telco modular jack on the front panel. The serial ports are configured for use as to modem and cannot be changed without null modem cables.

HARDWARE PREPARATION

AND INSTALLATION 2

Introduction

This chapter provides unpacking instructions, hardware preparation, and installation instructions for the MVME712 family modules and the LCP2 adapter.

Unpacking Instructions

 

 

 

If the carton is damaged upon receipt, request that carrier's

N

ote

agent be present during unpacking and inspection of

 

 

 

 

 

 

 

 

 

 

equipment.

Unpack equipment from shipping carton. Refer to packing list and verify that all items are present. Save packing material for storing and reshipping of equipment.

MVME712x Module Preparation

To select the desired configuration and ensure proper operation of the MVME712x module, certain changes may be made before installation. These changes are made through jumper arrangements on the headers. The locations of the headers and connectors for the MVME712x are illustrated in Figure 2- 1 through Figure 2-4.

The modules have been factory tested and are shipped with factory-installed jumper configurations that are shown in the following paragraphs with each header description. The modules are operational with the factory-installed jumpers. The modules are configured to provide the system functions required for a VMEbus system. Changes may be made for the following reasons:

DSR Line Pull Up Select (J8, J9, J13, J14)

Serial Port 2/Modem Port 2 Select (J16, J17)

Hardwired as DTE (to modem). With the exception of the DSR line, no headers are provided on the module to change this configuration. To use the module as DCE (to terminal), a null modem cable must be attached.

Hardware Preparation and Installation

SCSI Termination

2

Because the MVME712x has no provision for SCSI connection, you must ensure that the SCSI bus is terminated properly. The LCP2 adapter has sockets (R1, R2, R3) for terminating the SCSI lines using three 8-pin SIP resistors. Refer to the Installation Instructions for use of the terminators.

MVME712B Module Preparation

No preparation of the MVME712B is necessary. The location of the connectors is illustrated in Figure 2-5.
