XV9738a自動化設(shè)備,ABB使用過程
執(zhí)行操作系統(tǒng)關(guān)閉。接通交流或直流電源斷開并從系統(tǒng)中卸下交流電源線或直流電源線。
根據(jù)需要卸下機箱或系統(tǒng)蓋，以便訪問VME模塊。
在通電的情況下插入或拆卸模塊可能會導(dǎo)致?lián)p壞至模塊組件。
在這種情況下，存在可能導(dǎo)致死亡的危險電壓設(shè)備搬運、測試和調(diào)整時要格外小心。

避免接觸集成電路的區(qū)域；靜電放電會損壞這些電路。
4.從前面板上卸下PCI填充板圖1-21。MVME2700上的PMC模塊放置5、將PMC模塊的邊緣連接器滑入前面板從后面打開并將PMC模塊放置在基座頂部板PMC模塊下側(cè)的四個接頭然后應(yīng)與相應(yīng)的連接器平滑連接MVME2700上的（J11/12/13/14）。
6.將兩個短Phillips螺釘穿過前部的孔PMC模塊的角落，進入MVME2700上的防區(qū)。擰緊螺釘。7.將MVME2700組件重新安裝到其正確的卡槽中。確保該模塊位于背板連接器中。不要損壞或彎曲接頭針腳。
8.更換機箱或系統(tǒng)護蓋，將系統(tǒng)重新連接到交流或直流電源，并打開設(shè)備電源。PMC承載板安裝PCI夾層卡（PMC）承載板安裝在RAM200上方MVME2700上的夾層和（如果已安裝）PMC模塊。你可以在MVME2700基板上堆疊多達兩個PMC載波板，用于額外的PCI擴展。要安裝下部PMC托架板，請參閱圖1-22，并按以下步驟進行：
1、將靜電帶系在手腕上。連接ESD的另一端將皮帶系在底盤上作為接地。靜電放電帶必須固定在在整個過程中，您的手腕和地面。
2、執(zhí)行操作系統(tǒng)關(guān)機。接通交流或直流電源斷開并從系統(tǒng)中卸下交流電源線或直流電源線。根據(jù)需要卸下機箱或系統(tǒng)蓋，以便訪問VME模塊。
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.
