Motorola MVME2600 manual System Considerations

Hardware Preparation and Installation

6.Secure the MVME761 in the chassis with the screws provided, making good contact with the transverse mounting rails to minimize RF emissions.

Note The cabling can be configured in a number of ways to accommodate various device and system configurations.

Figure 1-22shows one possible configuration. For more detailed information on installing the P2 adapter board and the MVME761 transition module, refer to the user’s manual (listed in Appendix D, Related Documentation).

7.Replace the chassis or system cover(s), making sure no cables are pinched. Cable the peripherals to the panel connectors, reconnect the system to the AC or DC power source, and turn the equipment power on.

Note Not all peripheral cables are provided with the MVME761; you may need to fabricate or purchase certain cables. (To minimize radiation, Motorola recommends shielded cable for peripheral connections where possible.)

System Considerations

The MVME2603/2604 draws power from VMEbus backplane connectors P1 and P2. P2 is also used for the upper 16 bits of data in 32-bit transfers, and for the upper eight address lines in extended addressing mode. The MVME2603/2604 may not function properly without its main board connected to VMEbus backplane connectors P1 and P2.

Whether the MVME2603/2604 operates as a VMEbus master or as a VMEbus slave, it is configured for 32 bits of address and 32 bits of data (A32/D32). However, it handles A16 or A24 devices in the address ranges indicated in Chapter 2, Operating Instructions. D8 and/or D16 devices in the system must be handled by the PowerPC processor software. Refer to the memory maps in Chapter 2, Operating Instructions.
