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.The MVME2603/2604 contains shared onboard DRAM (and, optionally,
secondary cache memory) whose base address is software-selectable. Both
the onboard processor and offboard VMEbus devices see this local DRAM
at base physical address $00000000, as programmed by the firmware. This
may be changed via software to any other base address. Refer to the
MVME2600 Series Single Board Computer Programmer’s Reference
Guide, listed in Appendix D, Related Documentation, for more
information.
If the MVME2603/2604 tries to access offboard resources in a nonexistent
location and is not system controller, and if the system does not have a
global bus timeout, the MVME2603/2604 waits forever for the VMEbus
cycle to complete. This will cause the system to lock up. There is only one
situation in which the system might lack this global bus timeout: when the
MVME2603/2604 is not the system controller and there is no global bus
timeout elsewhere in the system.
Multiple MVME2603/2604s may be installed in a single VME chassis. In
general, hardware multiprocessor features are supported.
