1 Safety
1.1 Intended Application
The CompactPCI (CPCI) system subrack, described in this manual, is intended
as a platform for a microcomputer system based on the CompactPCI Standard
PICMG 2.0 Rev.3.
The CPCI system subracks are designed for protection class IP 20 and can be
used only in the resp. environments.
For higher protection requirements, e.g. IP 54/55 you must install the system
subrack in a protective case.
CPCI system subracks are not end-products, so there is no valid approval for
this unit. In order to enable stand-alone functionality, additional elements are
required. An operational system is achieved only by way of appropiate CPCI
boards.
The completion and final testing of the units have been carried out, or at least
supervised, by qualified technicians. These instructions are directed exclusively
to these qualified technicians i.e.engineers, trained and qualified electricians
etc.
Make sure that:
• the finished system complies with the safety regulations currently applicable
in the country it is going to be used.
• the finished system complies with all other regulations and specifications at
the place and country of use, e.g. interference limits, approval by the tele-
communications authorities.

2.5 Power Supply
Power is provided through a 250 W ATX power supply with wide range input.
The power supply is located to the right of the card cage behind a perforated
front panel. The AC input is via an IEC 320-C14 connector at the back.
The mains on/off switch is located at the back close to the AC input connector.
With a DC switch at the front you can switch-off the DC outputs of the power
supply.
2.5.1 Grounding/Earthing
Hazardous voltage!
Parts of the power supply may be exposed with hazardous voltage. Always
remove mains/line connector before carry out any assembly work.
Caution!
Your system has not been provided with a AC power cable. Purchase a
AC power cable that is approved for use in your country. The AC power cable
must be rated for the product and for the voltage and current marked on the
product's electrical ratings label. The voltage and current rating of the cable
should be greater than the ratings marked on the product.
Caution!
The unit is designed inaccordance with protection class 1! It must therefore be
operated with protective earth/GND connection. Use only a three conductor
AC power cable with a protective earth conductor that meets the IEC safety
standards!

2.6 Cooling
Figure 3: Fan Tray
The CPCI boards are cooled by forced air convection through two 12 VDC axial
fans (109 m³/h (64 cfm) each).
The operating temperature is from 0°C to 50°C, but note that the power supply
starts derating at 50°C.
2.7 Remove/Install Fan Tray
The Fan Tray is locked into the chassis by a mini compression latch with
indicator red/green. In closed position the indicator shows green, in open
position the indicator shows red.
Remove Fan Tray:
• Turn the knob counterclockwise until the indicator shows red.
• Pull out the Fan Tray:
Install Fan Tray:
• Insert the Fan Tray into the slot
Turn the knob clockwise until the Fan Tray is locked into the chassis.(By turning
the knob clockwise, the cam is put into the latched position and the green
indicator appears. Once latched, a further turning of the knob makes the cam
starts its compression feature until the Fan Tray is locked.)

3 Installation
3.1 General Installation Guidelines
3.1.1 Unpacking
Consider the following when unpacking and storing the system:
• Leave the system packed until it is needed for immediate installation.
• After unpacking the system, save and store the packaging material in case
the system must be returned.
If the packaging is damaged and possible system damage is present, report to
the shipper and analyze the damage.
3.1.2 Ensuring Proper Airflow
• Install the system in an open rack whenever possible. If installation in an
enclosed rack is unavoidable, ensure that the rack has adequate ventilation.
• Maintain ambient airflow to ensure normal operation. If the airflow is blocked
or restricted, or if the intake air is too warm, an over temperature condition
can occur.
• Ensure that cables from other equipment do not obstruct the airflow through
the systems.
• Use filler panels to cover all empty chassis slots. The filler panel prevents
fan air from escaping out of the front of an open slot.
Caution!
When opening the shipping carton, use caution to avoid damaging the system.
Caution!
To maintain proper airflow, all open slots must be covered with filler panels.
The filler panel should include an airflow baffle that extends to backplane.

3.2 Rack-Mounting
This subrack system can be installed in 19“ equipment racks. The rack must be
accessible from the front and rear for equipment installation.
Mounting Instructions:
• Ensure that the rack is constructed to support the weight and dimensions of
the system.
• Install any stabilizers that came with your equipment rack before mounting
or servicing the system in the rack.
• Load the rack from the bottom to the top, with the heaviest system at the
bottom, avoid uneven mechanical loading of the rack.
3.3 Initial Operation
• Ensure that the system has not been damaged during transport, storage or
assembly.
• Check the Protective Earth (PE) resistance, should be < 0,1 Ohm.
• Switch on the system and check all CPCI voltages directly on the
backplane connectors before the board assembly.
Note: The ATX power supply requires a minimum load!
• Plug-in the boards
• Cover all open Slots with filler panels.
Warning!
Voltages over 60 VDC can be present in this equipment. This equipment is
intended to be accessed, to be installed and maintained by qualified and
trained service personnel only.
This eqipment is designed in accordance with protection class 1!
It must therefore be operated only with protective GND/earth connection!

4.2 Declaration of Conformity
SCHROFF CompactPCI system subracks are developed and manufactured
according to EN 60950-1.
SCHROFF CompactPCI system subracks are not end-products with
independent functionality as described in the definition of the EMC regulations,
and therefore a CE marking is not required. However, when CPCI cards are
assembled according to specification, the systems fulfill the requirements in
accordance with EMC Directive 2004/108/EG and Low-voltage Directive
2006/95/EG.
Interferenceresistanceandinterferenceemissionsarefactors which areheavily
influenced by the type and quantity of CPCI cards used in the system assembly.
Through the use of high quality line filters and EMC optimized enclosure design,
SCHROFF offers CPCI systems which serve as an ideal base for system
integrators, which comply with the prescribed limits of EN 6100-6-3 and
EN 61000-6-2
The systems are generally equipped with power supplies which possess
CE markings in accordance with EN 60950-1, EN 61000-6-3, EN 61000-6-2).
Before delivery a high-voltage, protective earth and functionality test is carried
out on each individual system.
