3.2 Backplane Input Power Distribution
DC input voltage distribution to backplanes is a function of the individual backplane. Input volt-
age connection capabilities range from single, bolt type, terminal lugs for individual voltage con-
nections 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.
Warning!
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 com-
ply 100% with the CompactPCI Power Interface Specification for connector
pinout are not used with Kontron backplanes which use the DIN type M con-
nector.
Failure to comply with this warning may result in damage to your equipment.

CONNECTOR TYPE DESCRIPTION
Bolt Terminals Special press-through threaded M3 bolt terminal
Faston/M4
M4 screw connection with and without 6.3mm*0.8mm strip male Faston
connectors.
Single Faston spade type connectors
ATX
20-contact, male, ATX connector for backplane input power supply on the
reverse side of the backplane; the ATX PSUs available on the market are
provided with a matching connector.
DIN Type M
32 position, 29-contact, female DIN type M power supply connector for
power supply input power and backplane input power
Positronic 47-Contact
47-contact, female, Positronic PCIH47 power supply connector for power
supply input power and backplane input power
Power Bar
Copper strapping bar (2.5 mm x 8.1 mm x nn, where nn is function of width
and number of backplanes installed in system)
This type of power connection is designed for backplanes which have no
other type of power connector
