38System architecture

Core/Net modules diagnose faults in field-replaceable units for all core hardware, including cables. In case of a failure, a message appears on the system terminal and on the LCD of the faceplate of the utility card.

Core to Core Ethernet connection (LAN1 to LAN2) between the CP PIV cards allows memory shadowing and dual-CPU operation.

The cCNI Transition cards connect the Core module cards to the 3PE cards in the Network modules. Each Core module contains between one and four cCNI cards. Since each cCNI card can connect up to two Network groups, each Core is connected to a minimum of two groups and a maximum of eight groups. The number of cCNI cards in a system depends on the number of Network groups in that system. The first cCNI card that connects to Network group 0 and group 1 is installed in slot c9 of each Core/Net module. Each additional cCNI card is installed in ascending order from slots c10 to c12.
