1.9 Power Backplane
The Schroff CompactPCI Serial power backplane accepts a pluggable power supply with SSI-
type connector. The power backplane provides +12 V payload power and for wake-up events
an additional +5 V Standby voltage. More information in the backplane‘s user manual,
order no.: 63972-334

1.10 Power Supply
The CPCI Serial system is powered by 300 W CPCI Serial plug-in power supplies with wide
range input (100 - 240 VAC). They provide 12 V payload power and 5 V standby power for CPCI
Serial boards.
The power supplies are plugged-in in dedicated slots at the left front side. The power supply
contacts via a SSI-type connector to a Power backplane.
The power input is provided by an AC mains/line module with IEC 320-C14 connector,
integrated mains/line fuses and line filter.
The fuse rating is 10 A slow blow (10AT).
Figure 6: AC mains/line module
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 an 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.

10 Cooling R1.0, January 2016
2 Cooling
The CPCI Serial boards and the power supplies are cooled by forced air convection through
three 12 VDC axial fans located in a hot-swappable fan tray.
2 different fan trays are available:
• Fan Tray with Fan Control Module (FCM), status LEDs and RESET button
(3 fans with 220 m³/h (130 cfm)).
• Fan Tray with constant speed fans
(3 fans with 140 m³/h (85 cfm)).
An air filter is available as an option for both fan trays.
Figure 8: Fan Tray with FCM
The fan speed is determined by a temperature sensor above the card cage. Up to 40 °C the
PWM is 20%, from 40 °C to 60 °C the PWM is increased continously from 20% to 100%.
This control characteristics can be changed by a DIP switch on the FCM. (See user manual,
order no.: 63972-312)

2.1 Air Filter
An air filter is avalaible as an option. The air filter can be fixed with a mounting frame at the
bottom of the fan tray.
The filter meets the requirements of the Telcordia Technologies Generic Requirements GR-
78-CORE specification.

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
mustbe 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 sys-
tems.
• 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 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.
• Plug-in the boards.
• Cover all open Slots with filler panels.
•Switch on the system.
Warning!
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 Service
4.1 Technical support and Return for Service Assistance
We generally recommend to return the complete system. For all product returns and support
issues, please contact your Schroff sales distributor.
We recommend that you save the packing material. Shipping without the original packing
material might void the warranty.
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 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.
Interference resistance and interference emissions are factors which are heavily 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.
