CP3004-SA
2.7.8 CompactPCI Interface
The CP3004-SA supports a flexible CompactPCI interface with a hot plug power interface (no PCI hot
swap). In the system slot the PCI interface is in transparent mode, and in the peripheral slot the Com-
pactPCI interface is isolated so that it cannot communicate with the CompactPCI bus. This mode is
known as "passive mode".
2.7.8.1 Board Functionality when Installed in System Slot
In a system slot, the CompactPCI interface is provided as 32-bit / 33 MHz (66 MHz upon request) PCI
interface. The CP3004-SA supports up to seven peripheral slots through a CompactPCI backplane.
Note:
The PCI clock signals to unpopulated peripheral slots must be disabled by using the
kboardconfig uEFI Shell command. This is essential to maintain conformity to the CE
mark and the FCC EMI requirements. Please contact Kontron for further information.
Note:
The CP3004-SA supports universal PCI V(I/O) signaling voltages with one common resistor
configuration. For both 5V and 3.3 V PCI signaling voltages, 2.7 k
Ω
pull-up resistors are
used.
2.7.8.2 Board Functionality when Installed in Peripheral Slot (Passive Mode)
In a peripheral slot, the board receives power but does not communicate on the CompactPCI bus; all
CompactPCI signals are isolated.
2.7.8.3 Front / Rear I/O Configuration
The CP3004-SA is available in two versions:
»
CP3004-SA front I/O version
»
CP3004-SA rear I/O version
Please ensure that the correct version is stated on the order. If the CP3004-SA is ordered with rear I/O
configuration, various I/O interfaces and signals are available via the CompactPCI connector J2, such
as USB, SATA, GbE, VGA, COM, power and management signals. If the CP3004-SA is ordered with front
I/O configuration, the I/O interfaces and signals mentioned above are isolated from the CompactPCI
connector J2.
Note:
The CP3004-SA front I/O version does not provide 64-bit CompactPCI terminations to the
backplane via the CompactPCI connector J2. With regard to this aspect, the CP3004-SA dif-
fers from previous boards such as CP307 or CP308 where 64-bit CompactPCI terminations
are provided.
2.7.8.4 Board Insertion / Replacement under Power
The following features are implemented on the CP3004-SA:
»
Power ramping
»
ENUM signal handling (hot swapping of peripheral boards)
