4.1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
The objective of corrective maintenance is to detect
whenever an error has occurred, perform the necessary
repair, and bring the system 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 maintenance 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 verification
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. Each 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 a System 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 Troubleshooting 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/crates/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 the 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 maintenance & 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.
The BIT programs are used in offline troubleshooting
procedures.
4.2 S̲Y̲S̲T̲E̲M̲ ̲B̲R̲E̲A̲K̲D̲O̲W̲N̲
The CAMPS site equipment is broken down into logically
separated subsystems.
Section 4.2 shows the H/W modules included in each
of these subsystems.
The Offline Troubleshooting Tree (Section 4.3.3) is
also based on these subsystems.
The relationship between section 4.2 and 4.3.3 is as
follows:

The troubleshooting procedures of the CAMPS equipment
are described by two troubleshooting trees:
- System Troubleshooting Tree (refer to Section 4.3.2)
- Offline Troubleshooting Tree (refer to Section
4.3.3)
An overview of the main actions in the troubleshooting
procedures of the CAMPS equipment are presented in
Figure 4.3.1-1. An explanation of the Figure is given
below:
a) in Figure 4.3.1-1:
The troubleshooting of the CAMPS equipment starts
when an Error Report is printed at the maintenance
position (All the possible error reports are listed
in Appendix A) or if any deviation is deleted.
b) in Figure 4.3.1-1:
The System Troubleshooting Tree identifies the
first step in the troubleshooting procedure.
If a H/W error report is printed at the maintenance
position the next step in the troubleshooting procedure
is an identification of the first step (the Entry
Point) in the Offline Troubleshooting Tree. The
relation between the Error Report and the first
step in the Offline Troubleshooting Tree is presented
in Figure 4.3.2-1.
A H/W error report is generated by software modules
(ex: device handles) that are controlling a physical
device.
If a S/W error report is printed at the maintenance
position the further procedures are described in
Section 5.
A S/W error report is generated when one or more
errors are detected during the execution of a process
either by the process itself, by an accessed process
or by the central processing element.
If a deviation is detected in the equipment and
no error report is generated then the system troubleshooting
tree contains information about the strategy in
the troubleshooting procedures.
c) in Figure 4.3.1-1:
The Offline Troubleshooting Tree describes the
step-by-step procedures to be executed in order
to delete a H/W error from the CAMPS equipment.
d) in Figure 4.3.1-1:
Section 5.5 describes the procedures to be executed
from the moment of receiving a S/W error and to
the moment when the S/W error is deleted.
e) in Figure 4.3.1-1.
After the error is deleted the CAMPS system is
brought back to normal operation. This is done
by using the commands and procedures described
in the "MAINTENANCE POSITION OPERATION MANUAL".
f) in Figure 4.3.1-1.
When the system is brought back to normal operation,
the paperwork including logbook and Failure Reports
is completed (refer to Section 6).

The Offline Troubleshooting Tree specifies a method
to isolate a detected H/W error to a module.
Section 4.3.3.1 - 4.3.3.5 contains the Step-by-step
procedures to be executed when a H/W error is isolated
to a module.
Section 4.3.3 provides the following information about
the Offline Troubleshooting Tree:

There is a Fold-Out in Appendix C which
shows the relation between the Offline
Troubleshooting Tree and the CAMPS system.
The Appendix C specifies for each module
in the CAMPS configuration the offline
test sequence in the Offline Troubleshooting
Tree which tests the module. The testsequences
are identified by: "STEP".
Note that there is only one test sequence
per type of modules. (An example is
the LTU test sequence STEP 2500 - 2600).
The test sequence makes it possible
to test all modules in the CAMPS system.
Appendix C specifies also the relation
between the on line error reports and
the part of the CAMPS system which the
error reports relate. The on line error
reports are identified by: "REP-ID".
The Appendix C can be used during the troubleshooting
of the CAMPS system to illustrate which part of the
CAMPS equipment:
- the online error report relate.
- the steps in the offline troubleshooting tree test.
The following example illustrates the use of Appendix
C.

position:
This error report indicates that there is an error
in the LTUX-S module No: 11; i.e. the LTUX-S module
situated in slot 3 in the TDX crate # 1. (refer to
Appendix A).
The Fold-Out in Appendix C shows the relation between
the error report (indicated by REP-ID) and the first
step in the Offline Troubleshooting Tree. (indicated
by STEP).
The REP-ID in this example is TMS010. This REP-ID
is presented in the LTUX module in the TDX crate
in Appendix C.
The STEP presented in the LTUX module in Appendix
C shows the ENTRY POINT in the offline Troubleshooting
Tree.
The ENTRY POINT is: 4300.

The offline troubleshooting procedures are described
in step-by-step procedures, i.e. each step contains
a test. The result of this test specifies the next
step and so on until the error is traced to a faulty
module.
The structure of a test step is presented in Figure
4.3.3-1.

- P̲R̲O̲C̲E̲D̲U̲R̲E̲ (refer to the column b) in Figure
4.3.3-1).
The activating procedure of the test is specified
in the PROCEDURE column.
Some of the tests use the following character:
# ̲. The character identifies the module in test.
The exact identification of the module is specified
in Error Report printed at the maintenance position
in the "UNIT NO" column. A detailed description
of the possible "UNIT NO" parameters is given in
Section A.2 (refer to Appendix A).
The following types of activating procedures are
used:
1) An activation of an automatic test sequence. This
type is always activated by a command entered from
the maintenance position VDU.
* * * * * * * * * * * * * * * * * * * * * * * * * *
* *
An example is: TEST ALL (CR)
* * * * * * * * * * * * * * * * * * * * * * * * * *
* *
2) A manually activated test on a module.
* * * * * * * * * * * * * * * * * * * * * * * * * *
* *
An example is: Press the MC button on the front
of the MAP module.
* * * * * * * * * * * * * * * * * * * * * * * * * *
* *
3) Visual Test:
* * * * * * * * * * * * * * * * * * * * * * * * * *
* *
An example is: Check that the POWER LED is "ON"
on all the modules in the CU crate.
* * * * * * * * * * * * * * * * * * * * * * * * * *

Figure 4.3.3-1)
In the OBSERVATION/ACTION column are listed all
possible results of the test activated in the PROCEDURE
column. Each result is marked with an "o", and
contains a specification of the next step in the
troubleshooting procedure.
The correct option (marked with an "o") is selected
in the following way:
When a test is activated and finished the result
of the test is compared with the different results
listed in the OBSERVATION/ACTION column. The option
which is identical with the actual result of the
test contains a specification of the next step
in the troubleshooting procedure, which may be
one of the following types:
1) A̲c̲t̲i̲v̲a̲t̲i̲o̲n̲ ̲o̲f̲ ̲a̲n̲o̲t̲h̲e̲r̲ ̲t̲e̲s̲t̲.̲
The following mnemonics are used to define the
next step in the troubleshooting tree.
CONTINUE: Proceed with the next step in the
test sequence.
GO TO: Jump to another specified step in
the test sequence.
REPEAT: Repeat the same step to check if
an action has removed the error.
2) M̲a̲n̲u̲a̲l̲ ̲a̲c̲t̲i̲o̲n̲: The action is described.
An example of the contents of a OBSERVATION/ACTION
column is shown in Figure 4.3.3-2.
The example is explained below:
* * * * * * * * * * * * * * * * * * * * * * * * * *

E̲X̲A̲M̲P̲L̲E̲:̲
Step 2005 tests if it is possible to enable the FD
Ctrl. or not.
There are 3 different results each depending on the
kind of error in the system.
If the result of the command entered in the "PROCEDURE"
column is:
"FFFF"
" "
then it is possible to enable the FD Ctrl. and the
next step to be executed in step 2010.
If the result of the command entered in the "PROCEDURE"
column is:
"MAP STATUS A[[["
then it is not possible to enable the FD Ctrl. (unexpected
result) and the next step to be executed is step 2015.
If it was not possible to enter the command in the

The part of the CAMPS equipment which is tested
by the Offline Troubleshooting Procecures has to
be taken Offline before the tests begin.
It is, therefore, necessary to close down the Standby
PU, and the part of the CAMPS' equipment, which
will be involved in the Offline tests, before the
Offline troubleshooting starts. It is specified
in the Offline Troubleshooting Tree when it is
necessary to close down a part of the CAMPS equipment.
The close down procedures are described in section
5.3.6 in the "MAINTENANCE POSITION OPERATION MANUAL"
Doc. No. CPS/OPM/005.

This section describes the replacement procedures of
the modules, units, and crates mounted in the CAMPS
racks.
The replacement procedures of the peripherals and racks
are described in the peripheral manuals.
For the replacement of power distribution panels, signal
and power cables refer to the "INSTALLATION MANUAL".
After failure localization, normal system operation
is restored by replacement of the failed module/crate/unit.
The replacement is accomplished by different procedures
dependent on which type of assembly the module/crate/
unit is mounted in.
The different replacement procedures apply to module/crate
mounted in the following sections:

The task of the online error reporting is to report
whenever an error is detected. The report is printed
on the maintenance position line printer.
All the possible error reports are listed in Appendix
A.
When an online error report is printed on the maintenance
position line printer, it is possible via the System
Troubleshooting Tree (section 4.3.2) to identify the
entry point in the Offline Troubleshooting Tree (section
4.3.3).
The system troubleshooting Tree describes the relations
between the error reports and the entry points in the
Offline Troubleshooting Tree.
The Offline Troubleshooting Tree describes the test
procedures necessary when tracing an error to a module.

of the Built-In-Test (BIT) programs.
a) P̲u̲r̲p̲o̲s̲e̲
The purpose of a BIT program is to test the basic
functions in the module.
b) C̲h̲a̲r̲a̲c̲t̲e̲r̲i̲s̲t̲i̲c̲s̲
The test programs are characterized as Built-In-Test
programs. This means that it is an internal test
in the module and that the test program is stored
in the firmware of the module.
The execution time of the test is 5-10 sec.. A
"TEST" LED situated on the front of each module
is turned "ON" during the test.
If the "TEST" LED turns "OFF" after 5-10 sec. then
the test is successfully finished. If the "TEST"
LED remains "ON" then it indicates that the Built-In-Test
(BIT) detected an error in the module.
c) O̲p̲e̲r̲a̲t̲i̲o̲n̲
The BIT program is always executed during the power
up.
In the MAP module it is furthermore possible to
activate the BIT program manually or by a software
command.
