Each row entry represents a CPM card or module in a chassis in the
system. Entries cannot be created and deleted via SNMP SET
operations. When a tmnxChassisEntry is created, a tmnxCpmCardExtnEntry
is created for each CPM card or module in that chassis. Before a
tmnxChassisEntry can be deleted, each tmnxCpmCardEntry for that
chassis must be in the proper state for removal.
