instructions. If you are already logged in, continue with Step 2.
Install the OC-N cards that will serve as the BLSR trunk (span) cards if they are not already installed.
Step 2

runs on Nodes 4, 5, 6, and 7 and represents the subtending ring added by this procedure. Two BLSR
rings, Ring 1 and Ring 2, are provisioned on Node 4. Ring 1 uses cards in Slots 1 and 2, and Ring 2 uses
cards in Slots 3 and 4.
