Programming with SPM
The Boards option is also available in surrogate mode. In surrogate mode, you
can assign trunk and station modules (boards) to slots, even though those
boards have not actually been installed. Such boards are referred to as
"phantom boards" or "null boards."
NOTE:
If you assign phantom boards, they must be installed in higher slot numbers
than any real boards you assign. If you assign a phantom board to a lower
slot number than a real board, the control unit will not recognize the real
board(s) that follow the phantom board.
The following boards can be selected:

assigned to slots on the control unit. Note that phantom boards as well as real
boards are displayed with the Inspect function; to see phantom board
assignments, you must print the System Information report (System –> More –>
Print –> SysSet-up).
You cannot use this option to change a board type. All boards assigned with
the Boards option, including phantom boards, are cleared (unassigned), if you
perform a Board Renumber (System –> Board Renum).
