The CPU card and communication card are connected via the Ethernet
connections of the corresponding cards. Both the CPU cards and the
communication card must be connected to each other to ensure redundancy.
When operating with two CPU cards, the network module
(SAFEDLINK, CC)
must be removed from the communication card and fitted on the CPU card!
