1 Safety
1.1 Intended Application
The VME64x Tower System, 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 Tower Systems 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.

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.

2.5 Thermals
The front boards are cooled by forced air convection through 2 speed controlled
24 VDC axial fans (each fan 170 m³/h (100 cfm)).
The fans are assembled at the rear panel.
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 upper plenum, turns 90°, and is exhausted out the rear of the
subrack by fans.
The fan speed is controlled by the Fan Control Module (FCM) depending on the
exhaust temperature. The NTC temperatue sensor is located above the card
cage.
Figure 5: 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
• 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.

2.7 Display Module
Figure 7: Display Module
The Display Module is located at the upper 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.

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
• 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 Basic Functional Check
Before starting the system with VME boards the following tests have to be done:
• Ensure that the unit does not get damaged during tranport.
• Check the Protective Earth (PE) resistance, should be < 0,1 Ohm.
• Switch on the system and check all VME voltages on the Backplane
connectors before you plug in the VME boards.
Note: The +12 V output requires 10% minimum load, i.e. a resistor
12 Ohm / 12 W.
• Plug in the VME boards.
• Cover all open Slots with filler panels.
• Tighten the rear panel mounting screws.
• Power-on the system and determine the actual current consumtion.
• Replace the mains fuses suitable to the actual current.
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!
The fuse value has been determined in factory for the maximum power
delivered by the power supply. The fuse value must be adjusted to the actual
current consumtion of the completed system.
Maximum value is 8 A slow blow.

4 Service
4.1 Technical support and Return for Service Assistance
For all product returns and support issues, please contact your Schroff sales
distributor or www.schroff.biz.
We recommend that you save the packing material. Shipping without the original
packing material might void the warranty.
4.2 Declaration of Conformity
Microcomputer packaging systems are not complete units which can be
delivered directly to the end user, other items need to be fitted.
As it is defined in the EMC standard, it is not designated as a device.
A CE symbol is therefore not required. However, the systems comply with all
requirements. Each individual component complies to the EMC standard
89/336/EWG and to the low frequency standard 73/23/EWG.
These systems are generally equiped with power supplies having the
CE symbol (EN 60950, EN 61000-6-3, EN 61000-6-2).
The choice of the mains filter is carried out by considering the limited values‘
curve, according to EN 55022 class B.
To warrant the interference immunity according to EN 61000-6-2, the shielding
attenuation is measured in the frequency range from 30 MHz to 1000 MHz
according to VG 95 373, Part 15.
The systems are developped and manufactured according to EN 60950. High-
voltage tests, protective earth tests and functions tests are done on each series
system.
