Data Transfer Between Redundant BSE Pairs
•
Data exchange between the redundant BSE-
pairs is carried out only external via Ethernet
•
On each CP-2017 a SM-2556 has to be
equipped
•
The slots for the redundant BSE-pairs are
predefined, in fact: 1+2, 4+5, 7+8, (10+11,
13+14 only in 17 slots mounting rack). (green:
representation in the picture)
•
The electrical connection between Central
Fibre Switch and SICAM 1703 component can
be up to 100 m
•
Depending on the slots of the basic system
elements the socket connectors for the
electrical Ax peripheral bus have to be
selected (for example: slots C1 and C2
socket connectors AXPE-C1 and AXPE-C2)
•
Power supply has to be redundant!
•
Redundant BSEs have to have identical
configuration and identical functionality
