4. Signalling Environment
4.1 V(I/O) Setting
There are two blocks of three high-current terminals (designated as V(I/O)) for connecting
V(I/O) to either the +5V or +3.3V power supply. V(I/O) must be connected either to the +5V or
the +3.3V input power. It is the responsibility of the system integrator to ensure that the
required signalling voltage is implemented and that the backplane P1 connector coding corresponds to the implemented signalling voltage.
Warning!
Using both 3.3V and 5V boards within the same backplane segment
may result in damage to your equipment. Please note that the presence of only one 5V board determines a 5V signalling environment.
The default setting is 5V.
4.2 P1 Connector Coding for V(I/O)
The CompactPCI Specification foresees coding of the P1 connector to correspond to the signalling environment of the PCI bus. For this reason, only boards with universal or the corresponding coding can be physically inserted into the backplane. PEP’s factory default setting
for V(I/O) is +5V and male, 1567 code, brilliant blue coding keys are used.
Warning!
Using boards with an inadequate signalling voltage may result in damage to your equipment. Therefore, when changing the signalling environment from 5V to 3.3V or vice versa, it is mandatory that proper
coding keys are used (refer to chapter 3 of the CPCI Backplane Manual, ID 24229, for details).
5. Interfaces
5.1 Power
This backplane is designed to accommodate several different schemes for power input. Pluggable 3U and 6U power supplies can be used as well as non-pluggable power supplies. In addition it is possible to extend the backplane’s power busses for adding additional power
supplies. Appropriate provisions have been made on both the left side as well as the right side
of the backplane for power bus extension
5.1.1 Terminal Type Power Input
Both bolt type terminals and Faston/M4 type terminals can be provided for inputting DC power
to this backplane. These terminals are primarily designed for extending the DC power busses,
but they can also be used with non-pluggable power supplies for providing primary DC power
input. Refer to Figure 2 for terminal locations.

CPCI Backplane PD11: CP6-BP8-P47-STD
5.1.2 Pluggable Power Supply and Line Input
The V1 ... V4 output voltages from the power supply unit to the backplane are connected via a
47-contact, female, Positronic type power supply connector.
The main power supply input power is connected directly to pins 45, 46, and 47 of the power
supply connector. The is accomplished by means of a single, closed barrel pass-through contact for each pin via the reverse side of the backplane.

5.2 Fan Connectors
The backplane is equipped with four connectors for supplying power for fan(s) and for connecting a fan speed control device. JP21/23 (FAN1/2), are 3-contact male connectors which
supply +12V for fan operation as well as the possibility to connect to a speed control device
for regulating air flow within the system sub-rack. JP22/24 (NTC1/2), are 2-contact male connectors which provide a separate connection for a speed control device and are designed to
be used in conjunction with JP21/23.
For fans that have their own speed control or where no control is required, pins 1 and 2 of
JP21/23 can be used. For external speed control of fans, pins 2 and 3 of JP21/23 and pins 1
and 2 of JP22/24 are used. Pin 3 of JP21/23 and pin 2 of JP22/24 are connected internally on
the board side to each other.
External air flow regulation can be accomplished using a negative thermal coefficient (NTC)
device connected to JP22/24

5.5 System Monitor and Control Connectors JP11 and JP12
This backplane is provided with two connectors for system monitor and control signal interfacing to external devices. Both are 26-contact, male, double pin-row connectors, and have the
same signal pinout configuration. The system management bus (IPMB0), the power supply
monitor and control signals, and push button reset (PRST#) signal are all implemented on
these connectors.
