Motorola Single Board Computer, MVME5100 manual Manually Configured Headers/Jumpers

1

Hardware Preparation and Installation

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.
