CompactPCI Connectors
The complete CompactPCI connector configuration comprises five connectors named J1 to J5. Their functions are as fol-
lows:
•
J1, J2: management, IPMB and power, PCI is not supported
•
J3, J4 and J5 have rear I/O interface functionality, providing GbE to the backplane or RIO module and an RS232 inter-
face to a RIO module
The board supports signaling voltages V(I/O) of either 3.3 V or 5 V. No keying is required on J1 which designates universal
V(I/O).
The CP6940 is compatible with all standard 6U CompactPCI passive backplanes with rear I/O support on the system slot.
For accessing the GbE interfaces signals on connectors J3, J4 and J5 with a rear I/O module, a backplane with I/O support
is necessary.
