Maintenance Architecture
The maintenance subsystem is a part of the software that initializes and maintains
the system. The software continuously monitors system health, and keeps 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 maintenance strategy and the
background information on the system’s overall functions. For detailed
descriptions of components and subsystems, refer to related topics in
‘‘Maintenance Object Repair Procedures’’
How to use the Maintenance book
This procedure begins with the system raising an alarm against a Maintenance
Object (MO), a software module that monitors the components of a circuit pack.
These components can include:
■
Hardware
■
System (processor) availability and conditions
■
Presence of and physical connections (copper, fiber) to other components
■
Presence of certain signals (synchronization, DS1) within specific
parameters
■
Environment (power, cabinet temperature sensors)
