Physical port setting guidelines

It is recommended that you use the default settings listed in
Consider the Port class to be a superset containing the E_Port, FOP_Port, and FCU_Port
subclasses. If you make a change to a default setting for an area in the Port class, it applies to all of
the subclasses. This is convenient if you have determined that changes you plan to make to the
default settings for the subclasses are the same for certain areas. In this case, you only need to
make the changes to the Port class. Note, however, that if you make a change to one of the
subclasses, that change overrides the Port class setting.
