1 Safety
1.1 Intended Application
The VME system subrack, described in this manual, is intended as a platform
for a microcomputer system based on the VME bus system (VME (VITA 1-1994)
and VME64x (VITA 1.1-1997)).
The VME64x system subracks are designed for protection class IP 20 and can
be used only in the resp. environments.
For higher protection requirements, a.e. IP 54/55 you must install the system
subrack in a protective case.
VME64x 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 VME or
VME64x 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 assembled unit complies with the safety regulations currently applicable
in the country it is going to be used.
• the overall unit complies with all other regulations and specifications at the
place and country of use, e.g. interference limits, approval by the telecom-
munications authorities.

2.6 Power Supply
The subrack system has a open frame AC power supply with wide range input.
The power supply is assembled on a drawer at the rear bottom side.
The power input is provided by a AC mains/line module with IEC 320-C14
connector, integrated mains/line fuses and line filter.
A mains/line switch is located at the lower rear side.
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.
The maximum fuse values is:
• 8 A at 230 VAC Mains voltage
• 15 A at 110 VAC Mains voltage
2.6.1 Grounding
There is a M6 threaded stut located at the back side. This connector is only for
equipotential bonding. Grounding is achieved through the protective earth
conductor of the power cable!
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.
Caution!
The unit is designed in accordance 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!

2.7 Thermals
The 10 U VME64x system subrack contains two interchangeable Fan Trays.
The Fan Trays are plugged-in at the rear top of the system behind a bottom-
hinged front panel and are hot-swappable.
Each Fan Tray contains a 24VDC radial fan (500 m³/h (295 cfm) each).
The air enters the subrack at the lower front into the bottom air plenum and turns
90° upward. 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 Fan Trays, 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. The average temperature increase at full load is 12 K.
Figure 6: Air Flow
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.

2.8 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
• Controls the Display Module
• 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 temperature sensors can be connected to 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.
The FCM also controls a Display Module. 4 green LEDs signal the 4 VME64x
voltages, two red LEDs signal over-temperature and fan fail events.

2.9 Chassis Monitoring Module (CMM) -optional-
The Chassis Monitoring Module (CMM)
• monitors the four VME64x voltages
• can monitor two additional voltages with a range of ±24 VDC
• can monitor up to seven NTC temperature sensors
• can communicate with the Fan Control Module (FCM)
• provides 16 digital inputs
• provides 10 digital outputs
The CMM is an optional assembly and not included with the subrack by default..
The CMM allows communication and remote monitoring via RS-232 or Ethernet
interface. The front panel provides a RJ45 connector (Ethernet) an a D-Sub9
connector (RS-232).
A user interface via HTML page is available.
The CMM can monitor the 4 VME64x voltages and two additional voltages (up
to ±24 VDC). The error status can be displayed by LEDs, through the RS-232
serial interface or via ethernet as a HTML page.
Up to 7 NTC temperature sensors can be connected to the CMM.Two alarm
thresholds between 20° C and 70° C can be set.
The CMM provides 16 digital inputs and 10 digital outputs for custom specific
applications. Four digital outputs are open collector outputs, isolated by opto-
couplers, six digital outputs are TTL-compatible non-isolated.
The CMM is connected to the FCM. The temperature values and the fan speeds
are transferred to the CMM.
For more information see the CMM’s User Manual, Order No.: 73972-084 and

2.10 Display Module
Figure 8: Display Module
The Display Module is located at the lower front side of the subrack. 4 green
LEDs signal the 4 VME64x voltages, two red LEDs signal over-temperature and
fan fail events.
The Display Module is controlled by the FCM.
When a CMM is present, the Display Module is controlled by the CMM.

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.

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 brackets and a rack mount kit come with the system. Allow sufficient
clearance around the rack for system maintenance.
Mounting Instructions:
• Ensure that the rack is constructed to support the weight and dimensions of
the Shelf.
• 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.
• We recommend to use also chassis support brackets.
Warning!
Do NOT move the a full equipped system by yourself. Due to the weight at
least two persons are needed to accomplish this task
Warning!
Do NOT stack the system on top of any other equipment. If the system falls, it
can cause severe bodily injury and damage the equipment.
