16 peripheral elements can be connected
•
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:

elements the socket connectors for the
electrical Ax peripheral bus have to be
selected (for example: slots C4 and C5
socket connectors AXPE-C4 and AXPE-C5)
