1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
1.1 S̲C̲O̲P̲E̲
This plan provides an overview of the task delegations
within the CAMPS maintenance program. It will describe
the elements in the program and thei implementation.
The maintenance concept will be presented and discussed.
1.2 M̲A̲I̲N̲T̲E̲N̲A̲N̲C̲E̲ ̲C̲O̲N̲C̲E̲P̲T̲
It is a main feature of the on-site maintenance philosophy
that corrective maintenance is carried out down to
module level for both processor eqipment and peripherals.
Defective modules are returned to depot for repair
or other disposition.
In most instances, the level of isolation and replacement
will be plug-in cards and modules. This principle
is especially emphasized in the centralequipment where
also the power supplies are plug-in modules and modules
in the Channel unit can be replaced with power ON so
that the operational integrity of the remaining system
is preserved while one module is being replaced.
The corrective mantenance to components level is restricted
to simple tasks as replacement of fans, fuses etc.
Another significant feature in the on-site maintenance
philosophy is that troubleshooting with open doors
in the EMI racks is kept to a minimum. Most o the
corrective maintenance can be performed from the operator
position terminal and often the doors need only be
open in order to replace the defective module.

2.1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
This section outlines the engineering efforts necessary
prior to commencement of the on-site maintenance.
It describes the toolsnecessary to keep up the versatile
duties connected with the on-site maintenance and explains
the tools which are prerequisites for effective handling
and control of the CAMPS equipment.
2.2 M̲A̲I̲N̲T̲E̲N̲A̲N̲C̲E̲ ̲D̲O̲C̲U̲M̲E̲N̲T̲A̲T̲I̲O̲N̲
The Technical Manual togeter with the various OEM manuals
(test equipment and peripherals) provides all necessary
documentation for maintenance of the CAMPS equipment.
The reference document for site maintenance is the
Technical Manual vol. 1, Maintenance Manual, while
thereference document for depot maintenance is the
Technical Manual vol. 2, Technical Description. Both
manuals are self-contained documents which through
references addresses other relevant documentation.
Thus, both volumes describe the organizatio of manuals
for the applicable maintenance level.
2.2.1 S̲i̲t̲e̲ ̲L̲e̲v̲e̲l̲
Fig. 2.2-1 illustrates the applicable documentation
for the total site maintenance tasks, and the following

The Maintenance Manual is the reference manual for
the complete maintenance of a CAMPS site. It is divided
into sections of which the most important are described
below.
Maintenance Documentation
Fig. 2.2-1…86…1 …02… …02… …02… …02…
2.2.1.1.1 S̲y̲s̲t̲e̲m̲ ̲C̲o̲n̲c̲e̲p̲t̲
The system concept contains a break-down of a CAMPS
site into assemblies and sub-assemblies and it relates
the firmware to both hardware and software thrugh a
system description. The application and function of
the M&D software is discussed and so is also the formats
of error print-outs on the maintenance position Line
Printer.
2.2.1.1.2 F̲a̲i̲l̲u̲r̲e̲ ̲R̲e̲p̲o̲r̲t̲s̲
This section explains in detail the Faiure Reporting
System and describes how to use and fill in failure
reports. (The Failure Reporting System is described
in sec. 2.3).
2.2.1.1.3 L̲o̲g̲b̲o̲o̲k̲
A logbook is supplied to be effective from the start
of the Provisional Site Acceptance (PSA. All irregularities,
errors, and configuration changes, f.inst. due to preventive
maintenance operations, must be written in the logbook.
This section in the manual describes how the logbook
is maintained. (The logbook is described in sec. 2.3.).
2.2.1.1.4 P̲r̲e̲v̲e̲n̲t̲i̲v̲e̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲
This section contains a full description of the preventive
maintenance tasks at a CAMPS site. A major asset is
the preventive maintenance schedules which specifies
whenever a unit needs maintenance. There re schedules
covering all different types of peripherals and instruments,
and corresponding sub-sections will briefly describe
the set-up, prerequisites, tasks, etc.
a) The maintenance of the central equipment is described
in detail. All necessay information about test
instruments, tools, consumables, and test figures
are described.
b) A separate sub-section contains the preventive
maintenance schedule of the peripherals involved.
References are made to the respective OEM manuals
which will serve as the apprpriate documents for
the peripherals. There will be one schedule for
each type of peripheral.
c) The Test Equipment (TE) will generally require
little or no maintenance, but where preventive
maintenance is necessary, the same philosophy as
in "b above applies. If a regular calibration
is necessary this will most probably need to be
done at a depot. In such case a TE Calibration
Schedule will be found and the procedures described.
2.2.1.1.5 C̲o̲r̲r̲e̲c̲t̲i̲v̲e̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲
This section in themaintenance manual contains all
descriptions necessary for the isolation and repair
of an error down to module level. It is based on various
troubleshooting trees which provide a structured troubleshooting
procedure throughout the system. The errr print-out
at the maintenance position (or missing print-out)
will provide an entry point to a particular troubleshooting
tree and by following the descriptions outlined an
effective and time saving troubleshooting path is ensured.
Once the erro is isolated to a particular module, this
is interchanged with a spare module and a verification
test is performed before the application programs are
reloaded and the system brought back to normal operation.
2.2.1.2 T̲e̲c̲h̲n̲i̲c̲a̲l̲ ̲D̲e̲s̲c̲r̲i̲p̲t̲i̲o̲n̲ ̲(̲V̲o̲l̲.̲ ̲2̲)̲
This volume is intended for depot level and will only
be applicable in cases where the interface between
two modules needs to be described
2.2.1.3 I̲n̲s̲t̲a̲l̲l̲a̲t̲i̲o̲n̲ ̲(̲V̲o̲l̲.̲ ̲3̲)̲
This volume is intended for the installation of the
system and will only be applicable in rare cases where
the cabling between the processor equipment and a peripheral
is defective or when the system is being expnded.
2.2.1.4 I̲n̲v̲e̲n̲t̲o̲r̲y̲ ̲(̲V̲o̲l̲.̲ ̲4̲)̲
The inventory manual contains a listing of all items
delivered to a particular site or depot. Refer to
sec. 2.3 for more detailed information.
2.2.1.5 P̲a̲r̲t̲s̲ ̲L̲i̲s̲t̲s̲ ̲(̲V̲o̲l̲.̲ ̲5̲)̲
This volume contains all parts fund in the central
equipment. There are two major sub-sections of which
the Mechanical Parts List shows an illustrated equipment
structure down to module level, while the Electrical
Parts List reflects modules down to components level.
The formeris primarily used at site level while the
latter is aimed at depot level.
2.2.1.6 D̲i̲a̲g̲r̲a̲m̲s̲ ̲&̲ ̲L̲a̲y̲-̲O̲u̲t̲s̲ ̲(̲V̲o̲l̲.̲ ̲6̲)̲
Herein all the detailed diagrams showing the components
are found. This will normally not be used at site
level.
2.2.2 D̲e̲p̲o̲t̲ ̲L̲e̲v̲e̲l̲
Fig. 2.2.2-1 provides a tentative illustration of the
applicable documentation for a depot level. As the
depot philosophy is not yet decided, the contents of

2.3.1 G̲e̲n̲e̲r̲a̲l̲
A Failure Reporting System will be established in order
to maintain the operation and overall performance of
the system. By an analsis of the errors reported,
it is possible to screen systematic failures and proper
action may be taken to avoid unnecessary down-time.
Where action is deemed necessary a resulting Field
Change Notice (FCN) will be generated enabling each
site or epot concerned to perform the retrofit.
Prerequisites for Failure Reports from the sites are
a properly maintained logbook and the documentational
error print-outs appearing on the maintenance position
Line Printer.
The official failure reportig system will start at
the Site Provisional Acceptance (SPA), but in-house
registration and analysis will commence at the start
of factory acceptance test.
2.3.2 I̲n̲f̲o̲r̲m̲a̲t̲i̲o̲n̲ ̲F̲l̲o̲w̲
Any failure occurring at a site or depot will initiate
an informtion flow, refer to fig. 2.3.2-1. A failure
report will be generated (refer to sec. 2.3.4-1) and
sent via SHAPE to CR-ILS which will analyse, file,
and distribute for further examination. If a resulting
change is recommended, an Engineering Chang Proposal
(ECP) is sent to a Configuration Change Board (CCB)
which in turn may issue an Engineering Change Order
(ECO). ILS will then prepare a Field Change Notice
(FCN) under configuration mgmt, QA, and Project Office
control. The FCN will be snt through SHAPE to the
affected sites and/or depots.…86…1 …02… …02… …02… …02…
Information Flow
Fig. 2.3.2-1…86…1 …02… …02… …02… …02…
The FCN, which may prescribe a H/W design change, S/W
modification, or a spare part change, must be implemented
by the RST, and upon completion an acknowledgement
must be returnedthrough SHAPE to CR-ILS' file to close
the item. An FCN is considered closed only when acknowledgement
is received from all sites/depots concerned.
One exception to this information flow exists when
the FCN is concerned with change of spare part in which
case the change will be subject to approval by SHAPE.
In case the spare part change is a consequence of
a H/W design change, an FCN containing all relevant
information will be issued as a proposal to SHAPE within
4 weeks from the H/W chage. After their consent, the
proposal will be promoted to become an FCN. In case
a spare part will no longer be produced the above procedure
applies, now, however, not later than 9 months before
the item will no longer be produced.
It is worth oting that the failure reports' file may
be employed in screening for systematic errors. If
necessary, copies of the logbook and error print-outs
covering the observed time span must be accessible
to CR.
2.3.3 M̲o̲d̲u̲l̲e̲ ̲F̲l̲o̲w̲
If an error occurs a a site, the problem can most often
be traced down to a defective module which will be
replaced, usually from stock. The module is returned
to a repair depot and simultaneously another spare
module is sent to the site from a depot which will
be relenished from the repair depot. Refer to sec.
6.3.
The shipment from a site to the repair depot must be
covered by a failure report.
2.3.4 F̲a̲i̲l̲u̲r̲e̲ ̲R̲e̲p̲o̲r̲t̲s̲
When a failure report (refer to fig. 2.3.4-1) is filled
in at a site, one copy is filed for information, one
copy is sent to SHAPE, and one together with a ossible
module to the repair depot. When the repair is completed,
the failure report is also completed and one copy is
filed, one copy is sent to SHAPE, and one copy is filed
at CR.
The failure reports, which are numbered in succession,
contain sections. The first section is the identification
part which is filled in by the originator, the second
section applies only to the sites, while the third
section applies to depots only.…86…1 …02… …02… …02… …02…
