The tmnxCardEquippedType indicates the IOM card type that is physically
inserted into this slot in this chassis. If the slot has been
pre-provisioned, tmnxCardAssignedType is not equal to 1 (unassigned),
and the value of tmnxCardEquippedType is not the same as
tmnxCardAssignedType, a mis-match alarm will be raised.
A value of 0 indicates the IOM card type is not recognized by the
software.
