Sorry, thought I had used the word 'Failure' somewhere. We had an issue recently where a module failed, that much so that it not longer showed available in the slot. The customer was concerned that they did not get a specific alarm for that type of failure. The only alarms they got where link failures but only failures of links on the remote side that had noticed the status change, the core itself remained error free (I believe), because the links no longer showed available. Thanks.
