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.
