Circuit Board Removal and Replacement
Peripheral circuit boards in iControl and in the iLink cartop box are connected along a central,
pluggable bus. The boards are mounted on slide-tracks so that, if you need to replace a board
you can loosen the mounting bolts of the boards above or below it, slide them away, then
loosen, slide, and remove the board you need to replace. In iControl, the central bus extends
both above and below the iBox.

Note
Before using iView to assign or reassign inputs or outputs to I/O boards, consult MCE so that
your job prints can be corrected. Remember that reassigning an input or output will also
require appropriate re-routing of the wiring.
