XV9738a自动化设备,ABB使用过程
执行操作系统关闭。接通交流或直流电源断开并从系统中卸下交流电源线或直流电源线。
根据需要卸下机箱或系统盖，以便访问VME模块。
在通电的情况下插入或拆卸模块可能会导致损坏至模块组件。
在这种情况下，存在可能导致死亡的危险电压设备搬运、测试和调整时要格外小心。

避免接触集成电路的区域；静电放电会损坏这些电路。
4.从前面板上卸下PCI填充板图1-21。MVME2700上的PMC模块放置5、将PMC模块的边缘连接器滑入前面板从后面打开并将PMC模块放置在基座顶部板PMC模块下侧的四个接头然后应与相应的连接器平滑连接MVME2700上的（J11/12/13/14）。
6.将两个短Phillips螺钉穿过前部的孔PMC模块的角落，进入MVME2700上的防区。拧紧螺钉。7.将MVME2700组件重新安装到其正确的卡槽中。确保该模块位于背板连接器中。不要损坏或弯曲接头针脚。
8.更换机箱或系统护盖，将系统重新连接到交流或直流电源，并打开设备电源。PMC承载板安装PCI夹层卡（PMC）承载板安装在RAM200上方MVME2700上的夹层和（如果已安装）PMC模块。你可以在MVME2700基板上堆叠多达两个PMC载波板，用于额外的PCI扩展。要安装下部PMC托架板，请参阅图1-22，并按以下步骤进行：
1、将静电带系在手腕上。连接ESD的另一端将皮带系在底盘上作为接地。静电放电带必须固定在在整个过程中，您的手腕和地面。
2、执行操作系统关机。接通交流或直流电源断开并从系统中卸下交流电源线或直流电源线。根据需要卸下机箱或系统盖，以便访问VME模块。
Perform an operating system shutdown. Turn the AC or DC power
off and remove the AC cord or DC power lines from the system.
Remove chassis or system cover(s) as necessary for access to the
VME modules.
Inserting or removing modules with power applied may result in damage
to module components.
Dangerous voltages, capable of causing death, are present in this
equipment. Use extreme caution when handling, testing, and adjusting.
3. Carefully remove the MVME2700 from its VMEbus card slot and
lay it flat, with connectors P1 and P2 facing you.
Avoid touching areas of integrated circuitry; static discharge can damage
these circuits.
4. Remove the PCI filler from the front panelFigure 1-21. PMC Module Placement on MVME2700
5. Slide the edge connector of the PMC module into the front panel
opening from behind and place the PMC module on top of the base
board. The four connectors on the underside of the PMC module
should then connect smoothly with the corresponding connectors
(J11/12/13/14) on the MVME2700.
6. Insert the two short Phillips screws through the holes at the forward
corners of the PMC module, into the standoffs on the MVME2700.
Tighten the screws.
7. Reinstall the MVME2700 assembly in its proper card slot. Be sure
the module is well seated in the backplane connectors. Do not
damage or bend connector pins.
8. Replace the chassis or system cover(s), reconnect the system to the
AC or DC power source, and turn the equipment power on.PMC Carrier Board Installation
PCI mezzanine card (PMC) carrier boards mount above the RAM200
mezzanine and (if installed) PMC module on the MVME2700. You can
stack up to two PMC carrier boards on the MVME2700 base board for
additional PCI expansion. To install the lower PMC carrier board, refer to
Figure 1-22 and proceed as follows:
1. Attach an ESD strap to your wrist. Attach the other end of the ESD
strap to the chassis as a ground. The ESD strap must be secured to
your wrist and to ground throughout the procedure.
2. Perform an operating system shutdown. Turn the AC or DC power
off and remove the AC cord or DC power lines from the system.
Remove chassis or system cover(s) as necessary for access to the
VME modules.
