Preparation

This section includes subsections on hardware configuration that may need to be performed
immediately before and after board installation. It includes a brief reminder on setting bits in
control registers, setting jumpers for the appropriate configuration, and other VME data
considerations.

Hardware Configuration

To produce the desired board configuration and to ensure proper operation of the MVME5100,
it may be necessary to perform certain modifications before and after installation. The following
paragraphs discuss the preparation of the MVME5100 hardware components prior to installing
them into a chassis and connecting them.
A software readable header/ switch register (S1) is available on the MVME5100. This switch is
not defined by the hardware and it is shipped in the OFF position, as are all the switches on this
board. This S1 switch is available for user-specific configuration needs via the control registers.
The MVME5100 provides software control over most of its options by setting bits in control
registers. After installing it in a system, you can modify its configuration. For additional
information on the board's control registers, refer to the MVME5100 Single Board Computer
Programmer's Reference Guide listed in
It is important to note that some options are not software-programmable. These specific options
are controlled through manual installation or removal of jumpers, and in some cases, the
addition of other interface modules on the MVME5100. The following table lists the manually
configured jumpers on the MVME5100, and their default settings.
If you are resetting the board jumpers from their default settings, it is important to verify that all
settings are reset properly. For example, the SBC mode requires setting jumpers 4, 10 and 17
for rear Ethernet functions, but it also requires resetting jumpers J6 and J20. Neglecting to
reset J6 and J20 could damage or destroy subsequent PMCs or PrPMCs installed on the base
board at power-up.
