Procedure 19
Connecting the shelf 0 FIJI Ring cables (ascending)
Create Fiber Ring 0. Connect the FIJI cards in all Network shelves 0 in
ascending order, from Tx to Rx ports (see
on page 72
).
The shortest Fiber Cable must always be used.
The cables from group 0 to group 1 must always be the
same length as the cables from the last group back to
group 0.
The distance between the lengths of each fiber ring from
group 0 to any other group must not exceed 50'. Rings
are directional. Ring 0 is ascending and ring 1 is
descending.
Note: When adding an additional network group, fiber
cables must be changed to adhere to the rules above.
Remove the black cap from the end of each cable before it is connected.
Note: Each end of the NTRC48xx cable is labeled "Tx" or Rx" in the
factory.
1 Start with group 0, shelf 0.
2 Connect a NTRC48xx FIJI Fiber Ring cable of the appropriate length from
the Tx (J1) port of the FIJI card in Group 0, shelf 0 to the Rx (J2) port of
the FIJI card in Group 1, shelf 0.
3 Connect a NTRC48xx FIJI Fiber Ring cable of the appropriate length from
the Tx (J1) port of the FIJI card in Group 1, shelf 0 to the Rx (J2) port of
the FIJI card in Group 2, shelf 0.
