To avoid error, connect fiber-optic cable so that the farthest slot to the right represents the east port, and

the farthest slot to the left represents the west port. Fiber connected to an east port at one node must plug

into the west port on an adjacent node.

Do not provision the BLSR east and west ports on the same OC-N card.

Plan your fiber connections. Use the same plan for all BLSR nodes.

Plug the fiber into the Tx connector of an OC-N card at one node and plug the other end into the Rx

connector of an OC-N card at the adjacent node. The card displays an SF LED if the transmit and receive

fibers are mismatched.
