这就是为什么表B-1和表B-4显示针脚1没有连接。通常情况下，针脚7（信号接地）只应在一个点连接到底盘接地；如果多个端子与一台计算机一起使用时，该点的逻辑位置在计算机上。端子之间不应存在逻辑接地连接返回和机箱。
57120001-P5中文PDF说明书在线阅读介绍如果CPU板出现问题，请尝试简单的在寻求帮助或将电路板送回维修。一些程序将返回板到工厂调试器环境。董事会在这些情况下才离开工厂。自检可能不会全部运行用户自定义环境。1、确保系统已接通电源。2、检查电路板是否牢固安装在其内部背板或机箱。3、检查所有必要的电缆是否已连接根据本手册提交至董事会。4、检查是否符合系统要求注意事项，根据本手册。审查安装和启动程序，根据本手册。它们包括一步一步通电例行程序。试试看1。断开系统的所有电源。2.检查正确的调试器EPROM或调试器闪存是根据此安装的手册
3、重新接通电源。4、“双键复位”重启系统：按下按钮上的重置和中止开关同时；先释放重置，等待7秒，然后释放中止。5.如果出现调试提示，请转至步骤四或第五步，如图所示。如果调试提示不显示，请转至步骤六。对于VMEmodules，CPU板应位于第一个（最左侧）插槽。
2.同时检查“系统控制器”根据此，板上的功能已启用手册有一个
显示在终端，但输入来自键盘和/或鼠标没有效果。重新检查键盘和/或鼠标连接和权力。
That is why Table B-1 and Table B-4
show no connection for pin 1. Normally, pin 7 (signal ground) should only
be connected to the chassis ground at one point; if several terminals are
used with one computer, the logical place for that point is at the computer.
The terminals should not have a connection between the logic ground
return and the chassis.Introduction
In the event of difficulty with your CPU board, try the simple
troubleshooting steps on the following pages before calling for help or
sending the board back for repair. Some of the procedures will return the
board to the factory debugger environment. The board was tested under
these conditions before it left the factory. The self-tests may not run in all
user-customized environments.1. Make sure the system is plugged in.
2. Check that the board is securely installed in its
backplane or chassis.
3. Check that all necessary cables are connected
to the board, per this manual.
4. Check for compliance with System
Considerations, per this manual.
5. Review the Installation and Startup procedures,
per this manual. They include a step-by-step
powerup routine. Try it1. Disconnect all power from your system.
2. Check that the proper debugger EPROM or
debugger Flash memory is installed per this
manual.
3. Reconnect power.
4. Restart the system by “double-button reset”:
press the RESET and ABORT switches at the
same time; release RESET first, wait seven
seconds, then release ABORT.
5. If the debug prompt appears, go to step IV or
step V, as indicated. If the debug prompt does
not appear, go to step VI.For VMEmodules, the CPU board should be in
the first (leftmost) slot.
2. Also check that the “system controller”
function on the board is enabled, per this
manual. There is a
display on the
terminal, but
input from
the keyboard
and/or mouse
has no effect.Recheck the keyboard and/or mouse connections
and power.
