I have this alarm plus a COM_OFF alarm . All on 3 nodes that are connected together.
Welcome to the community, Charles! I'm sharing your question with members of our Optical Transport forum members should they have experience seeing the alarms and can provide insights and recommendations.
Can you please confirm the product and version? I'll also recruit some of our SMEs to help troubleshoot and provide a recommendation.
They are OME6500 transport nodes connected via CPL .
Thank you Charles!
Are you observing this alarm in OneControl ?
This indicates that the nodes have lost remote management on OneControl.
Please check if you are able to login the nodes through Site Manager.
Need to check for alarms appearing in the adjacent nodes (which are connected to unmanaged nodes and have remote management) to analyze further for the problem with unmanaged nodes.
If only management is lost and traffic is working, there could be issue with DCN configurations.
Yes I see it in One Control and I cannot login in through site manager .
Also no alarms on the adjacent nodes
In that case, there can be problem with Data Comms settings of the node.
Please refer to the Technical Document 323-1851-101_(Datacomms_Planning_Procedures) for Data Comms configurations in the node.
If you need any technical assistance for troubleshooting the issue, you may always open a case for Technical Support.
