The figures 5.5.1-2 and -3 identify the main assemblies/units
placed in the racks.
Fig. 5.5.1-1/3
5.5.2 C̲R̲8̲0̲D̲,̲ ̲M̲o̲d̲u̲l̲e̲s̲ ̲a̲n̲d̲ ̲A̲s̲s̲e̲m̲b̲l̲i̲e̲s̲
The CR80D system is a modular Processor system.
Three different units/crate assemblies are used in
the CAMPS MAIN SITE:
a) The Processor Unit (PU)
b) The Channel Unit (CU)
c) The Watchdog Processor (WD).
5.5.2.1 C̲R̲8̲0̲D̲ ̲P̲r̲o̲c̲e̲s̲s̲o̲r̲ ̲a̲n̲d̲ ̲C̲h̲a̲n̲n̲e̲l̲ ̲U̲n̲i̲t̲
Fig. 5.5.2-1 shows the assembly layout. The crate
assembly is for 19 inches rack mounting.
Functional modules are inserted in the front magazine
and in the rear magazine. Flatcables interconnect
front-modules with rear-modules.
To be able to access the interconnection cables when
the crate is mounted in racks, the rear crate can be
folded backwards. The depth required for allowing
fold-back is 910 mm.
The main functional modules are placed in the front
magazine.
Each front-module is terminated with 3 PC-Board edge
connectors placed on the rear edge of the module, opposite
the front panel.
Each of the 3 connectors are 86-way connectors.
The 3 connectors connect to 3 levels of motherboards,
placed in the rear end of the front crate, see fig.
5.5.2-2. The two upper motherboards are identical,
and carry the two main buses of the crate. The lower
motherboard provides no interconnection between front
modules, but is used for I/O signals in modules with
external connections.
Connectors for external signal cables are all placed
on the front panel of the rear crate modules. Interconnection
of front-and rear-crate modules is done by flatcable
as shown on fig. 5.5.2-3. The flatcable may be extended
to several Rear-crate-modules, where applicable.
Fig. 5.5.2-3 shows the normal adapter type rear crate
module. To terminate the main buses, main bus terminating
modules are used as indicated on fig. 5.5.2-1. In
the Channel unit is the bus terminating module carrying
the interface to the data channel in the one end (the
Channel Interface Adapter, CIA), see fig. 5.5.2-5.
Connectors for signal cables and external Power cables
(220 alt. 240 V, 50 Hz power source) are indicated
in figs. 5.5.2-4 and -5).
The two power source inputs of the PU connect to the
two power supply modules of the front crate working
in parallel, while the power source inputs A and B
of the CU connect to power supply modules supporting
the two redundant buses A and B.

Fig. 5.5.2-6 shows the assembly layout of the Watchdog
Processor assembly.
The CR80D minicrate used is designed for smaller stand-alone
computer systems.
Functional modules are inserted in the front magazine
and in the rear magazine. Flatcables interconnect
front-modules with rear-modules.
The main functional modules are placed in the front
magazine. Each module is terminated with 3 PC Board
edge connectors placed on the rear edge of the module,
opposite the front panel.
Each of the 3 connectors are 86-way connectors.
The 3 connectors connect to 3 levels of motherboards,
placed vertically in the rear end of the front magazine,
see fig. 5.5.2-6. The right board and the middle board
are identical and carries the two main bases of the
crate.
The left motherboard provides no interconnection between
front modules, but is used for I/O signals in modules
with external connections.
Connectors for external signal cables are all placed
on the front panel of the rear crate modules. Inter-connection
of front- and rear-crate modules is done by flatcable
as shown on fig. 5.5.2-3. The flatcable may be extended
to several Rear-crate-modules, where applicable. The
flatcables are accessed from the upper side of the
crate.
The power module is inserted from the rear and carries
the power source input.
Fans for cooling of front- and rear-modules are built
into the right sidewall of the crate.

5.5.2.3 C̲o̲o̲l̲i̲n̲g̲ ̲o̲f̲ ̲C̲R̲8̲0̲D̲ ̲C̲r̲a̲t̲e̲s̲
The watchdog crate assembly is cooled by built-in fans
blowing vertically through the side walls of crate.
The power supply and the fans have common power input.
The Processor and Channel Units are cooled by the dualized
CR80D fan assembly shown on fig. 5.5.2-7. The fan
assembly is placed beneath the unit to be cooled, see
fig. 5.5.2-8. The air input is at the front of the
fan assembly and air is blown up through the front
and rear magazines of the CR80D crate. The output
air stream is directed backwards and will leave the
rack through perforations in the top plate cover of
the rack.
The fan assembly contains 2 identical levels of fans
sourced by two separate Power inputs. Status indicators
on the front panel indicate errors of the fans. The
fans are easily inspected from the front.

The main switch assemblies are placed in the bottom
position of all racks of the 2 three-bay rack assemblies.
The main switch assemblies of a three-bay rack contain
the following functions:
a) The power lines fed into the racks are branched
into the amount of Power input sources required
by the units and assemblies of the racks.
b) Power switches and elapsed time indicators are
placed on the front panel. Each power input source
is distributed in the rack where the main switch
assembly is positioned and in some cases in the
neighbouring racks as required.
c) The power line filtering required for protection
against noise and spikes entering via the power
lines.
5.5.4.5 I̲n̲t̲e̲r̲m̲e̲d̲i̲a̲t̲e̲ ̲D̲i̲s̲t̲r̲i̲b̲u̲t̲i̲o̲n̲ ̲F̲r̲a̲m̲e̲ ̲(̲I̲D̲F̲)̲
All data exchange channels to users and external circuits
are passed through the IDF facility of rack F.
The principles of the IDF design are shown on fig.
5.5.4-1.
The IDF forms a cavity in the EMI shielding surface
of the racks.
Electrical cables are conducted from the crate/unit
containing LTUs and adapters to a position at the IDF,
where a feed through connector passes the signals through
the EMI shield, formed by the rack. The internal cables
are terminated with RF-filters.
Opto cables are passed through waveguides in the IDF.
All signal cables are leaving the rack through the
attached cable duct.
A cover has to be removed to get access to the connectors
terminating the external electrical cables.
5.5.4.6 P̲o̲w̲e̲r̲ ̲L̲i̲n̲e̲ ̲F̲i̲l̲t̲e̲r̲s̲
The power supply lines are entering the racks through
power line filters.
A power line filter is designed as a box placed on
the inside surface of the rack wall and forming a cavity
in the EMI surface.
Power line filters are placed in the one three-bay
rack-assembly, and the filtered power lines are run
to the other rack assembly through a separate power
cable duct.
Fig. 5.5.4-1
5.5.5 R̲a̲c̲k̲s̲
A CAMPS Main Site Installation includes 6 Racks, named
Rack A, B, C, D, E, and F.
The Racks serve 2 major tasks.
a) They contain a 19 inch Rack-system for mounting
of assemblies, units, and cables.
b) The 2 3-bay rack assemblies provide a TEMPEST shield
reducing electromagnetic radiation from the enclosed
equipment.
5.5.5.1 S̲i̲n̲g̲l̲e̲ ̲R̲a̲c̲k̲ ̲S̲p̲e̲c̲i̲f̲i̲c̲a̲t̲i̲o̲n̲s̲
Fig. 5.5.5-1 shows a single rack. The max. dimensions
shown give the maximum envelope of the rack.
The rack has 2 doors, a front door and a rear door.
The front door allows full access to the mounted equipment.
Front and rear door are of equal size and are hinged
at the same side of the rack.
The doors and the cabinet are made of steel.
Two perforated areas in the front door allow air intake
for cooling of equipment. The air intakes of the assemblies/units
are placed behind the perforated areas in the door
to minimize the pressure drop in each flow of cooling
air.
The top cover plate of the cabinet is perforated to
allow output of cooling airflow.
The gaps between doors and cabinet are blocked by gaskets
of conducting material.
The tightness of these gaskets are important for TEMPEST
performance. The gaskets are wear-out items with a
3 to 5 year service lifetime.
The 19 inch rack mounting panel system included in
the cabinet is mounted on insulation blocks and the
mounted equipment is thus galvanic insulated from the
Tempest Shield.
The "useful depth" of the rack is the distance between
the mounting surfaces of the front and rear mounting
panels. The useful depth is 101 cm.

5.5.5.2.1 T̲E̲M̲P̲E̲S̲T̲ ̲S̲h̲i̲e̲l̲d̲i̲n̲g̲
The 2 3-bay rack cabinets provide the TEMPEST shielding
of the equipment contained within the assembly, when
doors are closed. The 3 cabinets are bolted together
with conducting gaskets inserted. No side walls are
mounted between neighbouring cabinets.
A logical lay-out of 3-bay rack-assembly is shown on
fig. 5.5.5-2.
5.5.5.2.2 P̲o̲w̲e̲r̲ ̲C̲a̲b̲l̲i̲n̲g̲
The power cabling concept is shown on fig. 5.5.5-3.
Two set of tripple power filters are provided, one
set for the disk drives requiring stabilized power
and one set for the remaining assemblies/units.
The power switches indicated are the switches of the
Power Switch assemblies in the bottom position of each
rack panel.

Power and Weight data of the main site equipment racks
are tabulated in fig. 5.5.5-1.
The values shall be considered as typical and are valid
for maximum configuration of the site.
In fig. 5.5.5-2 is shown the phases of Start-up.
a) Initial peak period.
In the initial period is current defined by initial
currents due to saturation in transformers and
load currents for capacitors.
Period length and current waveform are depending
on the characteristics of the power source as well.
Peak current values of 10-50 times the current
value in use and a period length less than 100
ms are expected.
The power line filters inserted on the power lines
entering the CAMPS room will influence the initial
peak period.
b) S̲t̲a̲r̲t̲ ̲P̲e̲r̲i̲o̲d̲
The start period is defined by the start-up of
AC-motors in the racks.
AC motors are used in Disk units and Blower units.
The start period will be in the range 2-20 secs.
c) U̲s̲e̲ ̲P̲e̲r̲i̲o̲d̲
Use period characteristics are the characteristics
of the equipment in normal use after termination
of start-up phenomena.
The power and weight data of the individual racks are
tabulated in fig. 5.5.5-3.
The values shall be considered as typical.
