Maintenance Architecture

The maintenance subsystem is that part of the software that is responsible for

initializing and maintaining the system. This software continuously monitors

system health and maintains a record of errors detected in the system. The

maintenance subsystem also provides a user interface for on-demand testing.

This chapter provides a brief description of the R6r maintenance strategy, and

presents background information on the system’s overall functions. For detailed

descriptions of components and subsystems, refer to related topics in

Chapter 9,

‘‘Maintenance Object Repair Procedures’’. Sections on the following MOs are

particularly useful for gaining an understanding of how the system works:

■ STBY-SPE

■ PNC-DUP

■ EXP-PN

■ SNI-BD

■ DUP-INT

■ SYNC
