Warning
Turn the system’s power off before you perform these
procedures. Failure to turn the power off before opening the
enclosure can result in personal injury or damage to the
equipment. Hazardous voltage, current, and energy levels are
present in the chassis. Hazardous voltages may be present on
power switch terminals even when the power switch is off.
Never operate the system with the cover removed. Always
replace the cover before powering up the system.
Preparing the Board
To produce the desired configuration and ensure proper operation of the
MVME172LX, you may need to carry out certain hardware modifications
before installing the module.
The MVME172LX provides software control over most options: by
setting bits in control registers after installing the module in a system, you
can modify its configuration. (The MVME172LX registers are described
in Chapter 3 under ENV – Set Environment, and/or in the MVME172 VME
Embedded Controller Programmer's Reference Guide as listed in “Related
Documentation” in Appendix E.)
Some options, however, are not software-programmable. Such options are
controlled through manual installation or removal of header jumpers or
interface modules on the base board.
MVME172LX Configuration
Figure 1-1 illustrates the placement of the jumper headers, connectors, and
various other components on the MVME172LX. Manually configurable
jumper headers on the MVME172LX are listed in the following table (with
default settings enclosed in brackets).
