Step 2 Complete the following steps if you have not provisioned the path protection that you will interconnect
in a path protection DRI. If the path protection are created, go to Step 3.

Step 3 Verify that the path protection DRI interconnect nodes have OC-N cards installed and have fiber
connections to the other interconnect node:

This procedure provisions path protection in an integrated dual ring
interconnect (DRI) topology. In the integrated DRI, the path protection
OC-N trunk cards for both path protection are installed on the same shelf.

The OC-N cards that will connect the path protection must be installed at the interconnect nodes.
The OC-N cards in the path protection nodes and the interconnect nodes must be the same type.
The interconnect nodes must have the correct fiber connections. An example is shown in
on page 4-28. This example shows a path protection DRI with two rings, Nodes 1 through 4 and 5
through 8. In the example, an additional OC-N is installed in Slot 4 at Node 4 and connected to an
OC-N in Slot 2 at Node 6. Nodes 3 and 5 are interconnected with OC-N cards in Slot 2 (Node 3) and
Slot 4 (Node 5).
