Procedure 8-6
Deleting an 6200 network element from a
STM-4/OC-12 ring Configuration with 15G MRO XC
circuit pack
Use this procedure to delete an 6200 network element from a ring network.
Consider an STM-4/OC-12 ring with A, B, C, and D as 6200 network elements.
See Figure 8-5 on page 8-21. Network element C is to be deleted from the ring
as shown in Figure 8-6 on page 8-21.
Note: Traffic will be lost temporarily for all unprotected traffic between B
and D while the network element C is being deleted from the ring.
Prerequisites
• Log into the WUI of the immediate neighboring network elements (B and
D) of the network.
• Ensure that you note the following criteria in the neighboring network
elements:
— DCC bytes used
— WAN associations created
— cross-connects created
— synchronization scheme used
Action
Step Action
1 Query the following data of both the network element (B, D) and record the
values.
a. DCC bytes used
b. cross-connects created
c. synchronization scheme used
d. WAN associations created
2 Delete all cross-connections present in the other network elements of the
network, that terminate on the network element C.
