VIBRO 200-566-101-012模块使用流程
更换机箱或系统护盖，确保没有电缆挤压。用电缆将外围设备连接到面板连接器，然后重新连接将系统接至交流或直流电源，并转动设备打开电源。注：并非所有外围电缆均配备MVME761；你可能需要制造或购买某些电缆。（最小化辐射，摩托罗拉建议外围设备使用屏蔽电缆尽可能连接。）系统注意事项MVME2603/2604从VMEbus背板连接器供电P1和P2。
VIBRO 200-566-101-012模块使用流程P2还用于32位传输中的高16位数据，对于扩展寻址模式中的上八个地址行。这个如果没有主板，MVME2603/2604可能无法正常工作连接到VMEbus背板连接器P1和P2。MVME2603/2604是作为VMEbus主机还是作为VMEbus从机，配置为32位地址和32位数据（A32/D32）。然而，它处理地址范围内的A16或A24设备如第2章操作说明所示。D8和/或D16设备系统必须由PowerPC处理器软件处理。提到第2章操作说明中的内存映射。MVME2603/2604包含共享的板载DRAM（以及可选的，二级缓存），其基址是软件可选择的。二者都板载处理器和非板载VMEbus设备可以看到此本地DRAM在基本物理地址$00000000处，由固件编程。这可以通过软件更改为任何其他基址。请参阅MVME2600系列单板计算机程序员参考有关更多信息，请参阅附录D相关文件中列出的指南信息如果MVME2603/2604试图以不存在的方式访问非车载资源位置，并且不是系统控制器，如果系统没有全局总线超时，MVME2603/2604永远等待VMEbus循环完成。这将导致系统锁定。只有一个系统可能缺少此全局总线超时的情况：当MVME2603/2604不是系统控制器，也没有全局总线系统中其他位置超时。可以在单个VME机箱中安装多个MVME2603/2604。在里面一般支持硬件多处理器功能。
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.
