Step 8
Physically reroute the other protect fiber to connect the two end nodes. In the
fiber between Node 1/Slot 5 and Node 2/Slot 5 is rerouted to connect Node 1/Slot 5 to Node 3/Slot 13.
If you are leaving the OC-N cards in place, go to Step 13. If you are removing the cards, complete Steps
9 – 12. (In this example, cards in Node 2/Slots 5 and 13 are removed.)
In the middle node, place the cards in Slots 5 and 13 out of service:
