4.1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
The objective of corrective maintenance is to detect
whenever an error has occurred, perform the necessary
repair, and bring the sytem back to normal operation.
This is achieved by using the structured troubleshooting
procedures.
An overview of the corrective maintenance tasks is
given in Table 4.1-1.
The tasks are briefly explained below.
The error printout on the maintnance position printer
will provide an entry point to a particular troubleshooting
procedure and by following the descriptions outlined,
the error will be isolated to a particular module.
This is then interchanged with a spare module. A verificatio
test is performed before reloading the application
programs and bringing the system back to normal operation.
The structure of Chapter 4 is as follows:
- Section 4.2 describes a hardware (H/W) breakdown
of the CAMPS system into 5 sub-systems. ach of
the sub-systems is a logically separated unit which
is the first step in the error isolation.
This section gives an overview of the H/W included
in each of the logical sub-systems in which the
Off-line Troubleshooting Tree is divided.
Table 4.1-1
An overview of the corrective maintenance tasks
- Section 4.3 contains the troubleshooting procedures
in which the strategy of tracing a detected error
to a module is described. The troubleshooting procedures
are described by aSystem Troubleshooting Tree and
an Off-line Troubleshooting Tree.
The System Troubleshooting Tree contains the relation
between the error report printed on the maintenance
position printer and the first step (entry point)
in the Off-line Troublesooting Tree.
The Off-line Troubleshooting Tree contains a step-by-step
description of the test procedures necessary to
be executed when tracing a detected error to an
H/W module.
- Section 4.4 describes the replacement procedures
for modules/crtes/units mounted in the racks. These
procedures should be followed after the troubleshooting
procedures have isolated the error to a particular
module/unit/crate.
- Section 4.5 describes the controls, indicators,
switch settings, idle indication and input/output
(I/O) addresses of the modules within the CAMPS
system and is considered as a reference to the
troubleshooting procedures and replacement procedures.
- Section 4.6 describes the task of the on-line error
reporting programs, and he steps of troubleshooting
when an on-line error report is printed on the
maintenance position printer.
- Section 4.7 provides a description of activating
commands, printouts, and interpretation of error
codes for each of the off-line maintenanc & diagnostic
(M&D) test programs.
The off-line M&D test sequences are used in the
off-line troubleshooting procedures.
- Section 4.8 provides for each of the Built-in-Test
(BIT) programs a description of the activating
procedures and results.
