Chapter 14 Add and Remove Nodes
NTP-A240 Remove a BLSR Node
Step 10
Complete the
“DLP-A442 Verify Pass-Through Circuits” task on page 21-23
to verify that circuits
passing through the target node enter and exit the node on the same STS and/or VT. K3 extension byte
mapping is supported on all ONS 15600 OC-48 and OC-192 line cards, as well as the ONS 15454 OC-48
AS card.
Step 11
From the View menu, choose
Go to Network View
.
Step 12
Referring to the diagram created in
, complete the
“DLP-A303 Initiate a BLSR Force Ring
at each node that connects to the target (removal) node to force traffic away
from it. You must perform a Force switch at each port connected to the target node. For example, in
, you would perform a Force switch on the east port of Node 3 and the west port of Node 1.
Step 13
Click the
Alarms
tab.
a.
Verify that the alarm filter is not on. See the
“DLP-A227 Disable Alarm Filtering” task on
as necessary.
b.
Verify that no unexplained alarms appear on the network. If alarms appear, investigate and resolve
them before continuing. Refer to the
Cisco ONS 15454 Troubleshooting Guide
for procedures.
Step 14
Remove the fiber connections between the node being removed and the two neighboring nodes.
Step 15
If the two nodes that will be connected after the BLSR node is removed have OC-48 AS trunk (span)
cards and their K3 bytes were remapped, complete the
“DLP-A422 Verify BLSR Extension Byte
. If not, continue with
.
Step 16
Reconnect the fiber of the two neighboring nodes directly, west port to east port. For example, in
, the east port of Node 3 (Slot 12) connects to the west port of Node 1 (Slot 5).
Step 17
Complete the following substeps:
a.
From the View menu, choose
Go to Other Node
.
Choose one of the newly connected nodes and
click
OK
.
b.
Click the
Provisioning > BLSR
tabs.
c.
Choose the BLSR that originally contained the removed node, and then click
Ring Map
.
d.
Wait until the removed node is no longer listed.
e.
Repeat steps
through
for the other newly connected node in the BLSR.
Step 18
Complete the
“DLP-A196 Delete a BLSR from a Single Node” task on page 18-68
Step 19
Click the
History
tab. Verify that the BLSR_RESYNC condition appears for every node in the BLSR.
Step 20
Complete the
“DLP-A194 Clear a BLSR Force Ring Switch” task on page 18-66
to remove the Force
protection switches.
Step 21
According to local site practice, complete the
“NTP-A175 Two-Fiber BLSR Acceptance Test” procedure
.
Step 22
Complete the
“DLP-A371 Remove Pass-through Connections” task on page 20-55
Step 23
Log back into a node on the reduced ring. In the CTC Login dialog box, uncheck the
Disable Network
Discovery
check box.
Note
The deleted node will appear in network view until all SDCC terminations are deleted. To delete
SDCC terminations, complete the
“DLP-A156 Delete a Section DCC Termination” task on
Step 24
Click the
Circuits
tab and verify that no incomplete circuits are present. If incomplete circuits appear,
repeat Steps
