Side Cover
The VXIpc 770/870B Series is housed in a metal enclosure comprised of
a top and bottom cover to improve EMC performance and provide easy
handling. To access the jumper settings or install modules such as RAM or
PCI cards, you must remove the component side cover.
Remove the top cover by removing the screws that attach it to the module.
