The line card (SynoLOOP) FCL7201-Z3 determines the PIN assignment of the four
connection terminals in the card cage.
External connections on the card cage using the example of module bus card 1
with the associated connection terminals X11 and X12:
X12
4 3 2 1 4 3
8 7 6 5 8 7
● The external connections of module bus card 2 are on connection terminals
X21 and X22
● The external connections of module bus card 3 are on connection terminals
X31 and X32
● The external connections of module bus card 4 are on connection terminals
X41 and X42
● The external connections of module bus card 5 are on connection terminals
X51 and X52
Depending on the card cage, not all slots may be available for module bus cards
and connection terminals. However, the numbering and assignment of the
connection terminals are identical on all card cages.
