The subrack system has 19“ AC power supplies with wide range input.
The power supplies are plugged-in in two dedicated slots at the left and right
side of the backplane. The power supplies contact via a P47 connectors to the
backplane.
The power input is provided by a AC mains/line module with IEC 320-C14
connector, integrated mains/line fuses and line filter.
With a DC switch at the front side you can switch the power supply to standby
mode, i.e. the supply voltages to the backplane are shut off.
Maximum fuse value is 10 A.
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.
Warning!
The fuse value has been determined in factory for the maximum power
delivered by the power supply. The fuse value must be changed to the actual
current of the complete equipped system.

2.5 Thermals
The front boards are cooled by forced air convection through 3 speed controlled
24 VDC axial fans (290 m³/h (170 cfm) each.
The fans are assembled on a drawer behind the perforated front panel at the
bottom of the system.
The air enters the subrack at the lower front intothe bottom air plenum turns90°
upward and passes an air filter. As the air passes across the hot components on
the Front Boards, heat is carried away by forced convection. The air exits the
Subrack at the top, is drawn into the upper plenum, turns 90°, and is exhausted
out the rear of the subrack.
The fan speed is controlled by the Fan Control Module (FCM) depending on the
exhaust temperature. 3 NTC temperature sensors are located above the card
cage.
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.

2.6 Fan Control Module (FCM)
The Fan Control Module (FCM):
• Monitors and controls up to four fans
• Monitors the signals from up to four temperature sensors
• Speed up the fans in case of a failure of one fan
• Is able to communicate with the optional Chassis Monitoring Module (CMM)
Up to four NTC temperaturesensors can be connectedto the FCM.The highest
temperature level is the reference for the fan speed. If one ore more sensors
exceed 60° C the output for the temperature fail LED and a digital output are
activated. Since the fan speed is temperature controlled by the FCM, the fans
rotate with the lowest speed possible. Lower speeds reduce acoustic noise and
increase the longevity of the fans.

3 Installation
3.1 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.
3.1.1 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.
