The Kontron Modular Computers' backplane family includes both 3U and 6U form factor backplanes. 3U form factor backplanes are available with 2, 4, 5, 6, 8, and 11 slots. The 6U form
factor backplanes are available with 4 and 8 slots.
Depending on system requirements, the backplanes can be provided with a wide variety of
power supply connections: bolt type terminal lugs, screw lugs, Faston plug/M4 screw terminals,
ATX power supply connector, DIN type M pluggable power connectors, and Positronic type 47
position pluggable connectors.
In addition, backplanes are available: as 32-bit or 64-bit implementations; with either 33 or 66
MHz PCI clock; with rear IO configurations, telephony configurations; with system management bus (IPMB); with support for power supply redundancy and load sharing; and with support
for various monitor and control devices.
1.1Slot Assignment
A CompactPCI system board (backplane) is composed of up to eight CompactPC slots per
backplane segment with 20.32 mm center-to-center spacing. A CompactPCI backplane segment consists of one system slot and up to seven peripheral slots.
The functionality of the system master controller in the system slot is to provide bus arbitration,
clock distribution, and reset functions for all boards connected to the bus. In addition, it is responsible for performing system initialization and configuration.
The location of the system slot is always identified by a triangle below the corresponding P1
connector on the front side of the backplane. Peripheral slots are indicated by a circle.
Warning!
A system master CPU must be inserted into the system slot. The peripheral
slots may contain simple adapters, intelligent slaves, PCI bus masters or
peripheral master CPUs.
Physically, the system slot may be located at any position of the backplane. However, for simplicity and system expandability (heat-sink, cooling fan etc.), most Kontron Modular Comput-ers’ CompactPCI backplanes have their system slots on the right of the bus segment when
viewing the backplane from the front side.
The physical slot numbering of a backplane always begins at the upper left corner of the backplane and is always indicated on the board with appropriate markings.
The logical slot numbering which is a function of the IDSEL signal and the associated address
used to select the slot may differ from the physical numbering on the backplanes. When the
system slot is on the left of the backplane segment the logical slot numbering is from left to right
starting with one. When the system slot is on the right of the backplane segment the logical slot
numbering is from right to left beginning with one on the right. The relation between the two
numbering systems are shown in Figure 1. All Kontron Modular Computers' backplanes follow
this scheme.
The PICMG 2.0 CompactPCI Specification restricts the length of a bus segment of a given
CompactPCI backplane to 8 slots or less. This restriction has been determined by extensive
simulation and characterization and guarantees an optmimum operation of PCI-compliant integrated circuits. Since the inception of PCI, design engineers have extended this eight-slot restriction by using PCI-to-PCI bridge components. Thanks to the use of such bridge
components, which are put into effect using a special bridge module, the implementation of
CompactPCI backplanes providing more than 8 slots is possible.
P R E L I M I N A R Y
1.3Distinctive Features
The Kontron Modular Computers CompactPCI backplanes can be distinguished according to
the following distinctive features:
•Form factor (height and width)
•Number of slots
•Position of the system slot (primarily to the right)
The system slot provides clock signals for all the PCI peripherals in the system including devices on the system slot board. Each peripheral slot is provided with only one clock signal.
Clock numbering assignment begins with the slot adjacent to the system slot and is numbered
starting from 0.
Figure 2:Backplane Clock Assignment
Clock numbering:
5643210
Note ...
The CompactPCI Specification, 2.0, R2.1 requires only five discrete PCI clocks
to be available. Backplanes and system controller boards which support R2.1
but not R3.0 do not necessarily support seven PCI clocks. For this reason, it is
necessary to refer to the documentation provided with such backplanes or system slot boards to determine the actual clock output and numbering for the system.
Clock skew is the difference between the maximum and minimum propagation delay of any PCI
clock signal. There are two different types of clock skew: backplane and system slot board
clock skew.
The two concepts of backplane and system slot board clock skew are explained as follows.
2.1.2Backplane Clock Skew
A CompactPCI backplane provides the distribution of clock signals for all of the board slots in
the system. The differences in the trace routing and net topologies contribute to skew and also
define the longest clock delay. Particular attention is paid by the Kontron Modular Computers'
system design to meet overall system clock skew requirements namely through simulation,
testing, and qualification.
2.1.3System Slot Board Clock Skew
This is the clock skew that may be attributed to the onboard routing differences (if any) of all of
the PCI clocks as well as the skew specification for the type of integrated circuit driver used for
clock distribution. The onboard clock routing is designed to complement the propagation delays
of distributing the clock to a backplane and still meet overall system skew requirements.
3.Backplane Interfaces
3.1Power Supply Line Input Connections
Distribution of power supply main input power is a function of the individual backplane. Some
backplanes do not have any main input power distribution capability at all whereas others have
several possibilities.
Where a given backplane has distribution capability, main input power is either connected directly to the backplane power supply connector or, if available, to a separate LINE IN connector.
In both cases, AC as well as DC main input power may be connected depending on the type
of power supply to be used.
Refer to the individual backplane documentation for specific information concerning the con-
P R E L I M I N A R Y
nection possibilities.
Warning!
AC/DC power supply units must be installed only with backplanes/systems
connected to an AC mains power and DC/DC power supply units with backplanes/systems connected only to a DC mains power.
Failure to comply with this warning will result in damage to your equipment.
All Kontron Modular Computers’ backplanes and power supplies which use
the DIN type M power connector use contacts B2 and B5 for AC and DC
power supply input power. This differs from the CompactPCI Power Interface
Specification which calls for DC power supplies to use contacts B28 and B31
for input power.
This implementation simplifies backplane and power supply design making it
possible for a given backplane to use either an AC or a DC power supply.
System integrators, however, must ensure that DC power supplies which comply 100% with the CompactPCI Power Interface Specification for connector
pinout are not used with Kontron backplanes which use the DIN type M connector.
Failure to comply with this warning may result in damage to your equipment.
3.2Backplane Input Power Distribution
DC input voltage distribution to backplanes is a function of the individual backplane. Input voltage connection capabilities range from single, bolt type, terminal lugs for individual voltage connections to the 47-contact Positronic type PCIH47 connector. The following table summarizes
the various types of connectors used. For specific information regarding pinouts of backplane
connectors refer to the appropriate product documentation for the backplane in question.

GeneralCPCI Backplane
The following figures illustrate the various types of connectors used with Kontron Modular
Computers’backplanes.
Figure 3:Bolt Terminal, M4 Screw, Faston/M4, and ATX Connectors
Each CompactPCI backplane supports a 5V or a 3.3V signaling environment – V(I/O), and PCI
allows for two types of buffer interfaces for interboard connection. However, a gradual shift to
3.3V is occurring as the semiconductor industry shifts to the lower power interface for speed
and power dissipation reasons. For this reason, the Kontron Modular Computers system backplanes are also designed for 3.3V usage.
Warning!
Using both 3.3V and 5V boards within the same system may result in damage
to your equipment. Please note that the presence of only one 5V board determines a 5V signaling environment. The default setting is 5V.
When changing the signaling environment from 5V to 3.3V or viceversa,
please make sure that coding keys of the appropriate color are used (see Coding Keys section of this chapter).
3.4Rear I/O Connectivity
Rear I/O capability is a function of the individual backplane. Kontron Modular Computers pro-
vides both 3U and 6U backplanes with rear I/O functionality. Refer to Table 3 for information
regarding the rear I/O capability of Kontron’s backplanes. For the exact configuration (slots,
connectors, and pinouts) of rear I/O backplanes refer to the appropriate backplane product documentation.
3.5Flexible Grounding Option
With certain backplane types it is possible to select electrical isolation or connection between
the bus GND and the backpanel support PE (rack), thanks to the fact that every second fastening hole of backplanes is non-conducting. If only these fastening holes are used, there is no
electrical connection between GND and PE on the system bus. If additional holes are used, a
multi-point connection is created such as may be required for EMI protection purposes.
3.6Rack Dividers
P R E L I M I N A R Y
3U boards may be used in a 6U rack. If one or two 3U backplanes are used, a middle bar is
used to hold the 3U boards in place. If the 3U boards are installed on a 6U backplane, a split
kit must be used in place of the backplane’s P3 connector(s). For further information concerning split kits and middle bar separation refer to the appropriate product documentation.
Kontron Modular Computers CompactPCI systems present an advantage in
the form of a special combination of
coding keys. They ensure proper mating
of boards and backplanes in terms of
voltage and function. For this purpose,
two different kinds of coding keys have
been devised, which are described in
the following.
Backplane Keying
Proper board installation is ensured by
the use of colored coding keys for 3.3V
(yellow) or 5V (blue) operation, thus preventing incorrect installation of adapter
boards. This facility also prevents confusion when hot-swapping boards.
Additional Backplane Keying

Yellow: 3.3 V (NCR)
Blue: 5.0 V

The function of the additional board coding key depends on the backplane.
Backplanes equipped with an H110 telephony connector are marked with a red
H110 key. Dual-PCI backplanes use
coding keys for 3.3V (yellow) or 5V
(blue) operation of the upper PCI bus.
Rack Keying
Boards must be fitted into a CompactPCI backplane in a certain order, depending on whether they are bus master
boards or I/O boards. To this end, special asymmetrically shaped coding keys
can be used by the customer to ensure
that the boards are inserted properly.
