This object uniquely identifies the managed object on which
this fault is occurring.
For example, suppose a chassis has 2 power supply units PSU1
and PSU2. PSU1 is operational and PSU2 is in a failed state,
hence the MO representing PSU2 has a fault. Suppose the MO Id
of PSU2 is '1234' and its DN is 'sys/chassis-5/psu-1'.
The cucsFaultTable table would have an entry for the PSU fault.
The value of cucsFaultAffectedObjectId would be set to
'psuTable.psuEntry.1.1234'
and the value of cucsFaultAffectedObjectDn would be set to
'sys/chassis-5/psu-1'.
