Boards 8
The Boards option allows qualified service personnel to add a module to the
next available slot. The system must be idle to use this option. This option is not
available from the system programming console.
The Boards option is also available in Surrogate mode. In Surrogate mode, you
can assign trunk and extension modules (boards) to slots, even though the
modules have not actually been installed. This type of board is referred to as a
“phantom” or “null” board.
You cannot use the Boards option to change an actual module type. All
modules assigned with the Boards option, including phantom modules, are
cleared (unassigned) if you perform a board renumber (System
→Board
Renum).
■ You must assign phantom modules to higher slot numbers than those you
assign to any real modules. If you assign a phantom module to a lower slot
number than a real module, the control unit does not recognize the real
module or modules that follow the phantom module.
