14.4.22 BLSROSYNC
•
Major, Service-Affecting
The BLSR out of sync (BLSROSYNC) alarm occurs when the mapping table needs to be updated. To
clear the alarm, a new ring map must be created and accepted. Before you create a new ring map,
complete Steps 1 to 4 of the
“Clear the BLSROSYNC Alarm” procedure on page 14-19
.
Procedure: Clear the BLSROSYNC Alarm
Step 1
Prior to accepting a new mapping table, verify that each node has a unique node ID number:
a.
Login to a node on the ring.
b.
Click the
Provisioning >
Ring
tabs.
c.
Record the node ID number.
d.
Repeat Steps a to c for all nodes in the ring.
e.
If two nodes have the same node ID number, change one node ID number, so the node ID number is
unique within that ring.
f.
Click
Apply
.
Step 2
Verify that each node has a ring ID that matches the other node ring IDs:
a.
Login to the next node on the ring.
b.
Click the
Provisioning >
Ring
tabs.
c.
Record the ring ID number.
d.
Repeat Steps a and b for all nodes in the ring.
e.
If a node has a ring ID number that does not match the other nodes, change the ring ID to match all
the other nodes in the ring.
f.
Click
Apply
.
Step 3
Verify correct configuration of the east port and west-port optical fibers. (See the
.)
Step 4
If it is a four-fiber BLSR system, make sure that each protect fiber connects to another protect fiber, and
each working fiber connects to another working fiber. The software does not report any alarm if there is
a working fiber misconnected to a protect fiber.
Step 5
If the east-to-west configuration changes, click
Apply
.
The BLSR Ring Map Change window appears.
Step 6
Click
Yes
to accept the ring map.
Step 7
If the alarm does not clear, check the ring map for each ONS 15327 in the network and verify that each
node is visible to the other nodes.
