5. Connect fibers between Nodes B through D and Nodes D through C.
6. Verify the topology sees Node D.
7. Log on to Node C and remove the Forced Switch on the East Interface.
8. Log on to Node B and remove the Forced Switch on the West Interface.

Remove a Node from a Complete Ring

NOTE
• Mark the fibers before removing any fibers. Identify new fibers and mark
accordingly. Perform an OTDR to make sure the fiber span is clean and
note any TX and RX values.
• This process assumes that a four‐node ring exists and that the fourth node
is being removed. The first node will be identified as A, the second node as
B, the third node as C, and the fourth node as D.
• For more information on performing a Manual or Forced Switch, refer to
"Perform a Manual or Forced Switch" on page M‐2.
To remove Node D from the Node Ring, complete the following:
1. Verify that No Services are configured on the rest of the Nodes to the Node that is being
2. Log on to Node C and perform a Manual Switch on the East Interface.
3. Perform a Forced Switch on the East Interface.
4. Log on to Node B and perform a Forced Switch on the West Interface.
5. Disconnect the fibers to both the TX and RX on the East Interface on Node C. Disconnect
6. Connect the East RX of Node C to the West TX of Node B. Connect the East TX of Node C
7. Verify the topology sees a complete ring with Node C and B now being neighbors.
8. Log on to Node C and remove the Forced Switch on the East Interface.
9. Log on to Node B and remove the Forced Switch on the West Interface.
M-6
Disconnect both RX and TX on the West Interface on Node B and both RX and TX on the
East Interface on Node C.
Connect the East TX of Node C to the West TX/RX of Node D. Connect the East TX of
Node C to the West RX of Node D.
Connect the West RX of Node B to the East TX of Node D. Connect the West TX of Node
B to the East RX of Node D.
