1 Safety
1.1 Intended Application
The CompactPCI Serial system, described in this manual, is intended as a
platform for a microcomputer system based on the CompactPCI Standard
CPCI Serial CPCI-S.0.
The case systems are designed for protection class IP 20 and can be used only
in the resp. environments.
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 appropriate CPCI
Serial 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.

2.5.2 Load Resistor
TheATX PSU requiresminimumloads atthe 5V andthe 12V outputs.Because
the CPCI Serial Backplane need only 12 V supply voltage, a load resistor (10
Ohms / 5 W) is connected to the 5 V output.

2.5.3 Grounding/Earthing
12311823
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
The boards are cooled by forced air convection through two 12 VDC axial fans
(140 m³/h (85 cfm)).
The fans are located in a hot-swappable fan tray.
The operating temperature is from 0°C to 50°C.
Figure 6: Airflow
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 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
• 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 should
include an airflow baffle that extends to backplane. 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.

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 thebottom to the top, withthe 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 the supply voltage 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.
Mounting Kit
A rack mounting kit comes with the system.
Warning!
This equipment is intended to be accessed, to be installed and maintained by
qualified and trained service personnel only.

This equipment 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 systems are developed and manufactured according
to EN 60950-1.
SCHROFF CompactPCI systems 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 Serial 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.
Interferenceresistanceand interferenceemissionsarefactors whichareheavily
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.
