CompactPCI Interface
The CP6000 supports a flexibly configurable, hot swap CompactPCI interface. In the System
Master slot the interface is in the transparent mode, and in the peripheral slot the CompactPCI
interface is isolated so that it cannot communicate with the CompactPCI bus. This mode is
known as "passive mode".
2.3.14.1 System Master Configuration
In a system slot, the CP6000 can communicate with all other CompactPCI boards through a
32-bit/33MHz interface.
The CP6000 supports up to seven CompactPCI loads through a passive backplane.
The CP6000 is fully compliant with the PCI Local Bus Specification Rev. 2.2 for 32-bit/33 MHz.
2.3.14.2 Peripheral Master Configuration (Passive Mode)
In a peripheral slot, the board receives power but does not communicate on the CompactPCI
bus; all CompactPCI signals are isolated.
In this configuration the communication is achieved via the two Gigabit Ethernet ports as de-
fined in the PICMG 2.16 specification. In the passive mode the board may be hot-swapped.
2.3.14.3 Packet Switching Backplane (PICMG 2.16)
The CP6000 supports a dual Gigabit Ethernet link port (Node) on the J3 connector in accor-
dance with the CompactPCI Packet Switching Backplane Specification PICMG 2.16, Version
1.0. The two nodes are connected in the chassis via the CompactPCI Packet Switching back-
plane to the Fabric slots "A" and "B".
The PICMG 2.16 feature can be used in the system slot and in the peripheral slot.
2.3.14.4 Hot Swap Support
To ensure that a board may be removed and replaced in a working bus without disturbing the
system, the following additional features are required:
• Power ramping
• Precharge
• Hot swap control and status register bits
• Automatic interrupt generation whenever a board is about to be removed or replaced
• An LED to indicate that the board may be safely removed
2.3.14.5 Power Ramping
On the CP6000 a special hot swap controller is used to ramp up the onboard supply voltage.
This is done to avoid transients on the +3.3V, +5V, +12V and -12V power supplies from the hot
swap system. When the power supply is stable, the hot swap controller generates an onboard
reset to put the board into a definite state.
2.3.14.6 Precharge
Precharge is provided on the CP6000 by a resistor on each signal line (PCI bus), connected to
a +1V reference voltage. If the board is configured in the system master configuration, the ref-
erence voltage is disabled.
