HUCD420038R0001工控设备有关五排P2适配器的基本准备，请参阅下一节五排适配器在MVME761-011上，MVME761的五行适配器为68针母连接器（J1）承载来自MVME2700的16位SCSI信号基板。MVME761五行P2适配器的准备包括在以下情况下，在标头J5上安装跳线以启用SCSI端接电阻器：必需的图1-19显示了跳线头的位置连接器和SCSI终端电源保险丝（多路开关）R4。有关准备过渡模块和P2适配器，请参阅中列出的MVME761用户手册附录D，相关文件。硬件安装以下各节讨论了夹层卡在MVME2700基板，安装完整的MVME2700VME模块组装和转换模块到VME机箱中，以及与安装相关的系统注意事项。在安装之前MVME2700，确保串行端口和所有标头跳线根据需要配置。在大多数情况下，夹层卡是RAM200 ECC DRAM模块，可选PCI夹层（如适用）和可选载体板对于额外的PCI扩展（如果适用）-已在MVME2700。用户可配置跳线可通过安装夹层。如果有必要在基板上安装夹层，请参阅以下各节简要介绍了安装过程。使用ESD腕带摩托罗拉强烈建议您使用防静电腕带和安装或升级系统时使用导电泡沫垫。电子的组件，如磁盘驱动器、计算机板和内存模块，对静电放电（ESD）极为敏感。之后从其保护包装或系统中移除组件，将部件平放在接地的无静电表面上（在这种情况下对于电路板，元件面朝上）。不要将部件滑过任何表面如果ESD站不可用，您可以避免因以下原因造成的损坏：佩戴防静电腕带进行静电放电（电子商店有售）连接到有源接地的。请注意，系统机箱如果拔掉插头，则可能不接地。
P2 Adapter Preparation
The MVME761 transition module uses a three-row or five-row P2 adapter
to transfer serial, parallel, and Ethernet signals to and from the
MVME2700 series VME module.
Three-Row Adapter
On the MVME761-001, three-row P2 adapter, a 50-pin male connector
(J2) also carries 8-bit SCSI signals from the MVME2700 board.
Preparation of a three-row P2 adapter for the MVME761 consists of
installing a jumper on header J1 to enable the SCSI terminating resistors if
necessary. Figure 1-30 illustrates the location of the jumper header and
connectors on the MVME761’s three-row P2 adapter.
For basic preparation of the five-row P2 adapter, refer to the next sectionFive-Row Adapter
On the MVME761-011, five-row adapter for the MVME761, a 68-pin
female connector (J1) carries 16-bit SCSI signals from the MVME2700
base board.
Preparation of a five-row P2 adapter for the MVME761 consists of
installing a jumper on header J5 to enable the SCSI terminating resistors if
necessary. Figure 1-19 illustrates the location of the jumper header, the
connectors, and SCSI terminator power fuse (polyswitch) R4.
For further information on the preparation of the transition module and the
P2 adapter, refer to the user’s manual for the MVME761, listed in
Appendix D, Related Documentation.
Hardware Installation
The following sections discuss the placement of mezzanine cards on the
MVME2700 base board, the installation of the complete MVME2700
VME module assembly and transition module into a VME chassis, and the
system considerations relevant to the installation. Before installing the
MVME2700, ensure that the serial ports and all header jumpers are
configured as desired.
In most cases, the mezzanine cards—the RAM200 ECC DRAM module,
the optional PCI mezzanine (if applicable), and the optional carrier board
for additional PCI expansion (if applicable)—are already in place on the
MVME2700. The user-configurable jumpers are accessible with the
mezzanines installed.
Should it be necessary to install mezzanines on the base board, refer to the
following sections for a brief description of the installation procedure.
Use ESD
Wrist Strap
Motorola strongly recommends that you use an antistatic wrist strap and a
conductive foam pad when installing or upgrading a system. Electronic
components, such as disk drives, computer boards, and memory modules,
can be extremely sensitive to electrostatic discharge (ESD). After
removing the component from its protective wrapper or from the system,
place the component flat on a grounded, static-free surface (and, in the case
of a board, component side up). Do not slide the component over any
surface.
If an ESD station is not available, you can avoid damage resulting from
ESD by wearing an antistatic wrist strap (available at electronics stores)
that is attached to an active electrical ground. Note that a system chassis
may not be grounded if it is unplugged.
