Chapter 3
Understanding the Types of
Maintenance
There are several types of maintenance on the field replaceable units (FRUs) of the
SPARC M12.
This chapter first describes the types of maintenance and then describes, by model,
which types of maintenance are applicable to each FRU. The maintenance work
procedure varies depending on the type of maintenance. Before starting maintenance
work, fully understand the features of each type of maintenance so as to determine
the type to apply.
