The SPM provides a PMC I/O Module (PIM) interface that the SCM can use.
A connector is provided that is designed to support a unique processor daughter card that could
be used as a shelf manager on the SPM if a PIM is not used and no other shelf manager is
available in the shelf (see Figure 9, Interior connectors, on page 25).
