Numbering on the Submodule Receptacles

Each receptacle for an interface submodule has a submodule receptacle number
assigned to it. The submodule receptacle number depends on the module slot and
on the arrangement of the receptacle on the expansion module or the CPU. You
can see the submodule receptacle numbers in Figure 11-5.

You require these submodule receptacle numbers for configurations that you
undertake in the BIOS setup or for determining the I/O addresses of an interface
module (see the Chapter “M7-400 Expansions”).
