Chapter 2 Alarm Troubleshooting
2.6.8 APSCNMIS
Clear the APSCM Alarm
Step 1
Verify that the working-card channel fibers are physically connected directly to the adjoining node’s
working-card channel fibers.
Caution
Always use the supplied electrostatic discharge wristband when working with a powered
ONS 15600 SDH. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf
assembly.
Step 2
If the fibers are correctly connected, verify that the protection-card channel fibers are physically
connected directly to the adjoining node’s protection-card channel fibers.
Step 3
If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport
for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.
2.6.8 APSCNMIS
Default Severity: Major (MJ), Service-Affecting (SA)
Logical Object: STMN
The APS Node ID Mismatch alarm occurs when the source node ID contained in the incoming APS
channel K2 byte is not present in the ring map. The APSCNMIS alarm could occur and clear when a
MS-SPRing is being provisioned. If so, you can disregard the temporary occurrence. If the APSCNMIS
remains, the alarm clears when a K byte with a valid source node ID is received.
Clear the APSCNMIS Alarm
Step 1
Complete the
“Identify an MS-SPRing Ring ID or Node ID Number” procedure on page 2-122
to verify
that each node has a unique node ID number.
Step 2
If the Node ID column contains any two nodes with the same node ID listed, record the repeated node ID.
Step 3
Click
Close
in the Ring Map dialog box.
Step 4
If two nodes have the same node ID number, complete the
“Change an MS-SPRing Node ID Number”
to change one node ID number so that each node ID is unique.
Note
If the node names shown in the network view do not correlate with the node IDs, log into each
node and click the
Provisioning > MS-SPRing
tabs. The MS-SPRing window shows the node
ID of the login node.
Note
Applying and removing a lockout on a span causes the ONS node to generate a new K byte. The
APSCNMIS alarm clears when the node receives a K byte containing the correct node ID.
Step 5
If the alarm does not clear, use the
“Initiate a Lock Out on a MS-SPRing Protect Span” procedure on
to lock out the span.
